Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If water based cleaning methods are used, then cleaning effectiveness is improved, but water consumption increases and water recycling becomes difficult
Solution Approach 1:
The invention extracts the water from the cleaning system and replaces it with an air-based electrostatic cleaning mechanism. The electrostatic brush generates ions that attract and remove dust particles without requiring water, thereby maintaining cleaning effectiveness while eliminating water consumption and recycling issues.
Solution Approach 2:
The invention replaces the mechanical water-based washing system with an electrostatic field-based cleaning system. The electrostatic brush creates an electric field that selectively attracts dust particles to a collection chamber, substituting the mechanical water spray and collection method with an electrostatic mechanism that uses no water.
2Measurement precision
If motor gear rotation direction changes rapidly for bidirectional movement, then positioning accuracy is improved, but motor parts suffer rapid wear and tear
Solution Approach 1:
The invention incorporates a deceleration phase before direction reversal, where the motor gradually reduces speed before changing rotation direction. This cushioning approach prevents sudden shocks and mechanical stress on motor parts during direction changes, thereby reducing wear and tear while maintaining positioning accuracy through controlled deceleration and acceleration profiles.
Solution Approach 2:
The invention implements dynamic control of motor speed and acceleration during direction changes. Rather than abrupt reversals, the system dynamically adjusts motor parameters to smoothly transition between directions, optimizing the balance between positioning accuracy and mechanical stress reduction through real-time control of motion parameters.
3Reliability
If external power sources are used for cleaning systems in remote areas, then operational reliability is improved, but infrastructure complexity and cost increase
Solution Approach 1:
The invention makes the cleaning system self-powered by integrating a photovoltaic panel and battery system that independently generates and stores electrical energy. The electrostatic cleaning mechanism draws power from this self-contained energy system, eliminating the need for external power sources or complex infrastructure in remote locations while maintaining operational reliability through autonomous energy generation.

AI summary
The present invention relates to self powered and timer based solar panel cleaning system that is operated by self generating electrical power from solar energy and reduces wear and tear problem of moving parts. In this system, the microcontroller (54) is interfaced with motor driver (51) and brush driver (52). Said motor driver (51) and brush driver (52) control the speed of wheel motor (32) and brush driver (33). When ultrasonic sensor (5) sends signal to microcontroller (54), said microcontroller (54) generates and transmits signal to wheel motor driver (51) and brush driver (52). Thus, when structure reaches nearby the end edge of the solar panel array, said drivers gradually reduce r.p.m. of wheel motor (32) and brush motor (33) and then motors stop when machine reaches to opposite platform. Thus, during alteration of mode, r.p.m. of motors will be at substantially low that prevents the moving parts from damage.
