The document discusses problem solving using TRIZ. It describes an original problem of high electrical usage and costs due to energy conversion appliances. If solved, the benefits would be new renewable energy technologies that reduce costs and increase productivity. It then goes through the TRIZ problem solving process of function analysis, contradictions analysis, and applying inventive principles like segmentation and intermediaries to generate solutions like a segmented parabolic trough collector with a vacuum tube.

6. Engineering Contradiction
If the illumination intensity, extent of automation, and the loss in
energy is improved, then the overall efficiency / productivity of
the water heater is improved as well, but the device complexity,
ease of manufacture, and the area of moving components as well
as stationary components are further worsen.

#1 Segmentation
Design of the parabolic trough collector, where the trough surface,
supportive structure, and the conductor tube are mechanically fastened to
each other by means of pivot, screw, bolt and nut.
#19 Periodic Action
The driving motor only turns the trough surface when the sensor detects
and indicates that the sun have move out of the target area to reduced the
power input required to drive the motor, as well as lengthening the
motor's life.

#24 Intermediary
The conductor tube are made of excellent thermal insulating material and
the part of conductor tube that directly exposed to sunlight can be
replaced with a vacuum tube. Solar radiation can passes through the
vacuum tube and heat the water, while the tube itself greatly reduce
conductive and convective heat losses.
#30 Flexible Shell andThin Films
The parabolic trough surfaces are made of thin films, for example 3M film,
so that it is light yet rigid, allowing rotational movement driven by motor,
while able to sustain shearing torque and maintain the parabolic shape.
#35 Parameter Changes
With the implementation of a PTC model, the light ray concentration
greatly improved, whereby the parabolic surface reflects and concentrates
the incoming sunlight onto the conductor tube lay on the focal line. Next,
with the add-on of solar tracking system, the PTC system have a higher
degree of freedom whereby the trough surface moves in a manner
following the location of sunlight.
