Problem solving
Each technical problem has many mini-, midi- and maxi-solutions.
It is necessary to overcome 4 stages in the process of problem solving:
Stage 1. Problem definition and understanding its essence.
Stage 2. Problem analysis, search for all solution directions and the choice of those directions that are the most perspective.
Stage 3. Solution synthesis for selected solution directions.
Stage 4. Evaluation, testing and selection of obtained solutions, also tweaking them up to the end view.
Technovatics is orientated on use in the framework of the first three stages.
Elimination of breakages of spiral screws
inside balers of central type
Hohhot Branch of Chinese Academy of Agricultural Mechanization Sciences, Inner Mongolia.
Problem is connected with balers of central type equipped with spiral screws.
There are happened the breakages of spiral screws during operation of central type balers.
The breakages occur near the base of screw not immediately, but after a week-long operation.

Noise reduction at the back part
of bus passenger compartment
KIngLong Bus Company, Xiamen, Fujian province, China.
Problem is connected with tourist buses.
In the back part of bus the noise is more than in the front part. The measures applied by designers for protection from noise were insufficient.
It’s necessary to reduce the noise in the back part of bus passenger compartment.

Improvement of LEDs
Hualian Electronics Company, Xiamen, Fujian province, China.
Problem is connected with manufacturing of LEDs.
In the current design of LED the shoulders for holding of phosphoric glue have to locate far from chip to increase of LED radiation sector. But for all that the excess phosphoric glue is consumed and LED color varies considerably between central and lateral direction of its radiation.
It is necessary to reduce the volume of phosphoric glue used in the manufacturing of LED.
It is necessary to do thickness of phosphoric glue covering the chip approximately equal both from top and from sides.
It is necessary that the sector of LED radiation is not reduced, but on the contrary increased.

Improving of backlight of LCD TV monitors
Light Display Technology Company, Xiamen, Fujian province, China.
Problem is connected with LED backlight of LCD TV screens.
LEDs backlighting the screen of LCD TV monitor are placed on the sides of light panel.
It is necessary to reduce the irregularity of light flux after light panel (LGP).
It is necessary to increase the brightness of LCD TV (LEDTV) screen backlight.
It is necessary to increase the efficiency degree of light emitted by light diodes (LED).

Elimination of pneumocylinder rod wedging
in the machines for big detail machining
Xiamen Siert Robot Systems Company, Xiamen, Fujian province, China.
Problem is connected with equipment for machining of big details.
Big details are turned with help of spindle which is rotated by electric drive through the clutch with pneumatic cylinders.
Sometimes there are situations when the clutch pneumocylinder rods become wedged (when they enter or exit) in the holes of spindle.

Elimination of internal leak
in the brake master cylinders
Xiamen Josin Company, Xiamen, Fujian province, China.
Problem is connected with brake master cylinders of cars, namely with flow of braking fluid between sections of these cylinders.
Initially the levels of braking fluid in small and large sections of brake master cylinder are the same. But on-stream (in the process of braking) the level in small section falls and in large section grows.
It is necessary to reveal the cause of this defect and eliminate it.
Conceptual design
of device for transfer the dust
from robot vacuum cleaner into stationary dust collector
Samsung Electroncs, Suwon, South Korea.
Problem is connected with robot vacuum cleaners able to empty its dust collector automatically.
It is necessary to offer several variants of device for transfer the dust from robot vacuum cleaner into stationary dust collector.
Cost saving and increase of durability of laptop loops
Samsung Electroncs, Suwon, South Korea.
Problem is connected with laptop loops.
It is necessary to reduce the cost of manufacturing of laptop loops by reducing the number of details used in them.
It is necessary to increase the wear resistance of interacting surfaces of details of laptop loops.

Circumvention of patent on the virtual keyboard
of touch-screen phones
Samsung Electroncs, Suwon, South Korea.
Problem is connected with virtual keyboards of touch-screen phones.
The errors occur when you press your finger on the virtual key. These errors related to the accuracy of touch with small image of the key on the screen. To improve accuracy of touch it was proposed the solution in which the zoomed key image appears above the key.
How to circumvent this solution protected by a patent?
