Principe 7 : le placement interne

Duracell powercheck batteries

The Duracell powercheck batteries use a thin film of resistive material with heat sensitive crystals on top. By pushing the two dots, you close the circuit, and the resistive material will warm up. Depending on the temperature, the heat sensitive crystals change color. The higher the temperature, the more crystals will change color, which in turn is an indication of the shape the battery is in.

Principe 32 : le changement de couleur

Principe 14 : la sphéricité

Micro-Fiber Composite Actuator

A material that can act like "muscles and nerves" has been selected by NASA as the Government Invention of the Year. The composite material is composed of ceramic fibers that can bend or flex when a current is applied to them — much like a muscle. The material also generates a current when it is vibrated or flexed, giving users the ability to use the next-gen piezoelectric material as a vibration detector as well. The primary use of the material has been in helicopter blade research and vibration monitoring on the Space Shuttle launch pad and crawler. Non-aerospace applications include wind turbine blades, noise cancellation in commercial grade appliances, vibration dampening in performance sporting equipment such as skis, and even active vibration damping in the Audi TT drive shaft.

Principe 40 : les matériaux composites

Welding titamium using "bubble welding"

Titanium is a reactive metal that forms compounds with less than optimum properties. Heated in air, the part surface contains brittle carbides, nitrides, and oxides, each of which can reduce the fatigue resistance and notch toughness of the weld and heat-affected zone (HAZ). Not only do you need to protect the surface being welded, you also need to protect the back side of the weld, which is just as sensitive. This is why in many factories titanium welding is done in "glove boxes" in a complete inert environment.

Principe 39 : l'environnement inerte

Mourier Air Purifier

doctor's clinics are prone to attack of bacteria & viriuses from incoming patients. The air and environment in clinics, therefore needs constant purification. Mourier presents air purifier - using natures best oxidizing gas to disinfect bacteria and viruses, its use, eraducates bacteria and viruses contained in air. Also oxidizes and disinfects chemocal gases. It also de-odorizes stale and foul odours rapidly and leaves a pleasent fragrance.

Principe 38 : l'oxydation

Thermal expansion valve

A thermal expansion valve (often abbreviated as TEV, TXV or TX valve) is a component in refrigeration and air conditioning systems that controls the amount of refrigerant flow into the evaporator thereby controlling the superheating at the outlet of the evaporator. Thermal expansion valves are often referred to generically as "metering devices". Flow control, or metering, of the refrigerant is accomplished by use of a temperature sensing bulb filled with a similar gas as in the system that causes the valve to open against the spring pressure in the valve body as the temperature on the bulb increases. As temperatures in the evaporator decrease, so does the pressure in the bulb and therefore on the spring causing the valve to close. An air conditioning system with a TX valve is often more efficient than other designs that do not use one.

Principe 37 : l'expansion thermique

Laser measuring devices

Lasers are devices that use light, through a process of optical amplification, to emit a ray of light that is spatially and temporally coherent. Laser measuring devices are used primarily by surveyors, architects, golfers and hunters to measure the distance between two objects, which displays on an LCD screen. Providing extremely accurate results, lasers save time when measuring between two points such as ceilings and walls. Laser devices used for measuring range in price and technical sophistication depending on your needs.

Principe 35 : le changement d'état physique et chimique d'un objet

Artificial skin

The skin is the largest organ in the human body. Severe damage to large areas of skin exposes the human organism to dehydration and infections that can result in death.Traditional ways of dealing with large losses of skin have been to use skin from other parts of a patient's body (such the thigh) or from a different person/cadaver. The former approach has the disadvantage that there may not be enough skin available, while the latter suffers from the possibility of rejection or infection. To solve these issues, research is being done on artificial skin. Typically, a collagen scaffold is used (the protein that underlies the structure of skin), which can be additionally seeded with patient's own cells, or with foreskin from newborns that was removed during circumcision. Additional technologies, such as an autologous spray-on skin produced by Avita Medical, are being tested in efforts to accelerate healing and minimize scarring.

Principe 33 : l'homogénéité

Injection molding fusible core technique

Fusible core injection molding, also known as lost core injection molding, is a specialized plastic injection molding process used to mold internal cavities or undercuts that are not possible to mold with demoldable cores. Strictly speaking the term "fusible core injection molding refers to the use of a fusible alloy as the core material; when the core material is made from a soluble plastic the process is known as soluble core injection molding. This process is often used for automotive parts, such as intake manifolds and brake housings, however it is also used for aerospace parts, plumbing parts, bicycle wheels, and footwear.

Principe 34 : le rejet et le regénération

Smart packaging on milk bottle

This invention is a good example of a smart packaging and of color change. It features a special ink that possesses an inside ink reacting day after day with a color change, indicating its freshness.

Principe 32 : le changement de couleur

Porous polymer-ceramic bones

BAE Systems and the Office of Naval Research have jointly developed a new type of artificial bone capable of supporting new bone growth and simultaneously porous enough to be absorbed by the body. In current orthopedic implant materials, the affected bone is in danger of becoming too weak before substantial mass loss of the implant. With use of current materials such as copolymerized polylactic and polyglycolic acids (PLA/PGA) as bone fillers, patients may find bones are too weak to carry any load long before significant amounts of bone have grown to replace the eroded prosthesis . The ceramic coated biocompatible plastic would be broken down over the next 18 months by the body after bone cells had filled the pores in the ceramic. All that would remain of the implant would be some of the original polymer core encased in sturdy bone tissue.

Principe 31 : le materiau poreux

Inflatable tent

An inflatable tent is easily mobile, made of durable plastic material, and is resistant to rain, strong winds, and can withstand the harshest of weather conditions. Regular tents, which are in fact good to use for most occasions are not resistant to problems such as leaking seems, complicated set-ups, and the sheer hassle of lugging these things around. Blow-up tents are great for kids parties. These tents come in many styles, colors, and cool designs that kids will love.

Principe 29 : le système hydraulique ou pneumatique

Principe 28 : la reconception

Disposable contact lenses

Disposable contact lenses have become the most popular form of contact around the world. Worn for a set period of time and discarded for a fresh set, they are healthier for the eye and significantly reduce complications of long-term wear. The technology of lenses, as well as the material and comfort have all been improved over the years, and today wearers have more options than ever. Depending on the wearer and their schedule, there is usually a contact lens ideal for them.

Principe 27 : l'éphémère et l'économie

Adjustable Rolling Pin

The adjustable Rolling Pin will take the guess work out of preparing pizza and pie bases, lasagna sheets and filo pastry. The rolling pin has three sets of removable discs which raise the rolling pin to the required thickness of 1/16-inch, 1/4-inch and 3/8-inch off the work surface. This clever devise will ensure that the pastry or dough is rolled to an even thickness throughout. Also etched into the wood is a pastry width measurement guide. Pin made of beech and measures 16-1/2-inch long and 2-1/2-inch diameter.

Principe 24 : l'intermédiaire

Battenfeld Microsystem High Shear Rheology

A Rheometric nozzle capable of holding standard Rosand capillary rheometry dies was attached to the nozzle of the Battenfeld M50 as shown below. A charge of melt is produced by extruding directly into the injection chamber (bypassing the metering piston) and then the machine is told to inject, acting in the same manner as a conventional cappillary rheometer, with the pressure reading taken from the Dynisco force tranducer behind the injection pin. The main disadvantage of this method is that the pressure reading is not a direct melt measurement, it incorporates other forces such as the friction between the injection pin and nozzle. Even with no polymer in the injection chamber, a rise in force/pressure can be seen due to the friction between injection pin and barrel.

Principe 23 : l'asservissement

Noise energy harvester by Hung-Uei Jou

Some of the noisiest places on the planet are the airport runways. But designer Hung-Uei Jou decided to makes use of noise pollution to turn it into electricity. He designed a gadget dubbed Green Noise that is able to identify, trap and transform sound energy into power that can be used to power runways lights. The Green Noise has the shape of a conical speaker, which allows the device to catch sound waves easier. It stands on a tripod base and can work in any weather.

Principe 21 : l'accélération

The Igus C-chain

Igus has developed the igus C-Chain, which is claimed to be the world's first continuously circulating energy chain. The igus C-Chain can supply grippers, sensor systems and other devices with energy (electrical or pneumatic), data and other media without the need for non-productive starts and return runs. Not only are igus C-Chains lightweight and reliable, but with speeds of up to 8m/s they can also be used in high-speed machinery and in applications where short machine cycle times are required; depending on customer specifications, travels of 30m or more are possible. Numerous different carriages can serve rotating grippers, suction cups or electromagnets, for example, which can pick up work pieces, hold them, manipulate them and set them down again. Also, processing tools required for turning, clamping, adhesion or drilling can be supplied.

Principe 20 : la continuité d'une action utile

Peristaltic pump

A peristaltic pump, or roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained within a flexible tube fitted inside a circular pump casing (though linear peristaltic pumps have been made). A rotor with a number of "rollers", "shoes" or "wipers" attached to the external circumference compresses the flexible tube. As the rotor turns, the part of tube under compression closes (or "occludes") thus forcing the fluid to be pumped to move through the tube. Additionally, as the tube opens to its natural state after the passing of the cam ("restitution" or "resilience") fluid flow is induced to the pump. This process is called peristalsis and used in many biological systems such as the gastrointestinal tract.

Principe 19 : l'action périodique

Vibratory feeders

The bowl feeder, including an out feed accumulation track to convey parts along and discharge into the assembly machine are supplied in many shapes and sizes. The drive unit, available in both electromagnetic and pneumatic drives, vibrates the bowl feeder, forcing the parts to move up a circular, inclined track. The track is designed to sort and orient the parts in consistent, repeatable positions. The track length, width, and depth are carefully chosen to suit the application and component shape and size. Special track coatings are applied according to shape size and material of the parts which aids traction, damage to the product and lower acoustic levels. A variable speed control box is used for controlling the vibration of the bowl feeder and stops the flow of parts to the out feed track via sensors. Vibratory feeders are utilized n many industries including, pharmaceutical, automotive, electronic, food, Fast Moving Consumable Goods (FMCG), packaging and metal working industries. It also serves other industries such as glass, foundry, steel, construction, recycling, pulp and paper, and plastics. Vibratory feeders offer a cost-effective alternative to manual labour, saving manufacturer’s time and labour costs. Several factors must be considered when selecting a parts feeder, including the industry, application, material properties, and product volume.

Principe 18 : la vibration mécanique

Suma 3D controller mouse

The gaming industry is evolving at a momentum that’s sometimes makes it real hard to keep track of. With controllers being designed with all kinds of technology to enhance your gaming experience and some technology that don’t even require controllers like the much awaited Project Natal, it’s not just overwhelming but kind seemingly of expensive as well. Suma also introduced a new kind of 3D technology for the gaming industry with a new system of controlling games. Their 3D controller is constructed of sensors, an accelerometer and a squeezable foam core neatly packed into an oval form that looks like a little football with a wire.

Principe 17 : le changement de dimension

Dual flush toilets

Dual flush toilets handle solid and liquid waste differently from standard American style toilets, giving the user a choice of flushes. It's an interactive toilet design that helps conserve water that has caught on quickly in countries where water is in short supply, like Australia, and in areas where water supply and treatment facilities are older or overtaxed. The Environmental Protection Agency (EPA) reports that by the year 2013, an estimated 36 states will experience water shortages as a result of increased water usage and inefficient water management from aging regional infrastructures. Using less water to flush liquid waste makes sense everywhere.

Principe 16 : l'action partielle ou excessive

Dyson's Ballbarrow

The Ballbarrow was a type of wheelbarrow designed by James Dyson and released in 1974 in the UK. It featured a moulded plastic hopper on a steel frame and a spherical plastic wheel. This benefited all-terrain use as the ball did not dig into the ground like a conventional wheel and steering was much easier. The original design featured a galvanised steel hopper, which was so robust that many are still in use today. Later, the design was changed to a plastic hopper. The plastic hopper was considered easier to clean than galvanized steel alternatives; however, it was less robust, less suitable for mixing cement in and tended to age quickly in the sheds and garages it was typically stored in.

Principe 14 : la sphéricité

Wind tunnels

Wind tunnels were first proposed as a means of studying automobiles (primarily airplanes) in free flight. The wind tunnel was envisioned as a means of reversing the usual paradigm: instead of the air's standing still and the aircraft moving at speed through it, the same effect would be obtained if the aircraft stood still and the air moved at speed past it. In that way a stationary observer could study the aircraft in action, and could measure the aerodynamic forces being imposed on the aircraft.

Principe 13 : l'inversion

Self watering systems for plants

Self Watering Probes are a simple and effective way of watering your plants while you are on vacation. Just soak them in water for a couple of minutes to prepare the tips, then insert the probes into the soil of your potted plants and place the hose ends in a water reservoir nearby. The water will be slowly emitted through the ceramic cones, automatically watering your plants without the need to set timers or worry about electronic devices being turned on while you are away.

Principe 12 : l'équipotentialité

Lightweight cushioning material for transport protection

Some residual volume often remains unused in cartons or crates. The products to be transported can therefore be shaken about and become damaged. Air cushions are particularly suitable for fixing goods reliably in the shipping carton. Handling is very easy: a tube consisting of an air-filled film is divided into individual cushions at regular intervals. A perforation enables the air cushions to be easily separated, so that the right length can be adjusted perfectly – customized to suit your individual needs. This lightweight type of plastic packaging protects your goods against impact, scratches or other external forms of damage.

Principe 11 : la prévention

Manufacturing of mold cavities in injection molding

When cavities are designed in injection molding of plastic parst. The designer must take into consideration the shrinkage of the polymer being injected. This value is important since beforehand the dimetionning of the cavities must be different from the final dimetionning, taking into consideration the directional shrinkage of walls, holes and other surfaces. Sometimes, when the part is particularilly complex, the cavity is far from looking like the negative of the part due to the evolution of the cavity dimetionning.

Principe 9 : l'action inverse préalable

Prepasted wallpaper

In prepasted wallpaper, a thin layer of glue is applied to the back of the paper. This process takes place in the factory before the wallpaper is packaged for distribution and sale. The quality of the adhesive used varies from manufacturer to manufacturer and even from batch to batch. For its activation, the adhesive on the back of prepasted wallpaper must be activated before applying to the walls. This is generally done using water. A sponge saturated with water can be used or small pieces of the wallpaper can be soaked in a tray of water for several seconds. There are some alternatives to using water for activation. A special adhesive activator can be purchased that is made specifically for prepasted wallpaper. It is applied like paste and eliminates the need for water. There is also a product known as One Step Wallpaper Prep and Adhesive for prepasted wallpaper.

Principe 10 : l'action préalable

Exhaust Manifold Heat Riser

Heat riser valves are located between the exhaust manifold and the head pipe and are used to hasten the warm up of a cold engine. A malfunctioning or frozen valve can cause loss of power or exhaust manifold damage. To treat this problem, lubricate both ends of the shaft to which the heat-riser counterweight is connected. This is done with the engine cold.

Principe 8 : le contrepoids

Principe 5 : la combinaison

Valtek's dual Nested springs for piston cylinder actuator

For extremely high-pressure-drop-applications, a nested spring configuration (one spring inside another) can be used, as shown in Figure. Spring compression is applied by the introduction of an adjusting bolt, which compresses the spring to the required return force. Adjusting bolts of different lengths can be used to vary the spring compression. The cylinder is installed above the yoke with either a snap-ring arrangement or bolting.

Principe 7 : le placement interne

Nested slides

Nesting any interesting function (like a slide) in a lose place of a bigger one is an evident way of saving volume (like storage for instance).

Principe 7 : le placement interne

Motors for vibrating toothbrushes

Modern toothbrushes have an inside motor with an excentred weight on top of the axis provoking the vibration. Thanks to the asymetry of this cheap and light weight component the vibration is enabeled almost without any losses in the toothbrush ergonomy.

Principe 4 : l'asymétrie

Blended "Invisible" Bifocal

Although most bifocals and trifocals have visible lines at the border of lens segments, there is a blended round-seg bifocal that has a less noticeable near segment than its regular round-seg cousin. The near seg is blended into the distance portion of the lens so that it is virtually invisible. With no visible lines, the blended round seg bifocal offers a more youthful appearance than lined bifocals and trifocals. But a drawback of the blended bifocal is that the optics of the lens are slightly distorted at the blended border between distance and near zones. This may be bothersome to some wearers.

Principe 3 : la qualité locale

KoalKeeper separate good coals from ash

When one placed live coals in the trash along with the ash, mostly because of sleeping coals lie instead of cleaning the fireplace. Cutouts in this steel shovel let you separate good coals from ash. That means you keep embers necessary to get the fire going again once the stove is clean and you can be sure you aren't accidentally throwing burning coals in your ash can.

Principe 2 : l'extraction

Trifocal lenses

Trifocal eyeglass lenses have an additional ribbon-shaped lens segment immediately above the near seg for seeing objects in the intermediate zone of vision — approximately 18 to 24 inches away. This intermediate segment provides 50 percent of the added magnifying power of the near seg, making it perfect for computer use and for seeing your speedometer and other dashboard gauges when driving. Trifocals are especially helpful for presbyopes over age 50, who have less depth of focus than younger presbyopes, who may still be able to see objects at arm's length reasonably well through the top part of their bifocals.

Principe 1 : la segmentation
