Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional cleaning systems use external power supply, then the system can operate continuously, but the device complexity and installation cost increase due to cable requirements
Solution Approach 1:
The cleaning system generates its own electrical power through integrated solar panels that convert sunlight into electricity, eliminating the need for external power supply cables and complex electrical infrastructure in remote locations
Solution Approach 2:
The solar panels serve dual functions: generating electrical power for the motor and providing the cleaning surface, combining energy generation and cleaning operations in a single integrated system
2Speed
If the motor runs at peak level for rapid direction change, then the system responds quickly to sensor signals, but the motor parts suffer rapid wear and tear
Solution Approach 1:
The motor operates at variable speeds rather than constant peak level, dynamically adjusting its rotational speed based on operational requirements to balance quick response with reduced mechanical stress and extended motor life
Solution Approach 2:
The motor operates in periodic cycles of acceleration and deceleration rather than continuous peak operation, allowing mechanical components to settle and reducing cumulative wear during direction changes
3Ease of manufacture
If manual cleaning is performed early in the morning or late at night, then the solar panels are cleaned, but the productivity is reduced due to non-uniform power outage
Solution Approach 1:
The system performs self-cleaning during its operational hours using its own generated power, eliminating the need for separate manual cleaning operations and maintaining continuous productivity
Solution Approach 2:
The cleaning operation integrates seamlessly with the power generation process, allowing the system to maintain continuous useful action without interruption to power production

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.
