Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cleaning methods are used with climbing/elevation equipment, then cleaning can be performed on roof-installed panels, but the operation becomes dangerous and costly
Solution Approach 1:
The cleaning system is self-powered by converting water pressure into mechanical torque through a pressure-driven motor, eliminating the need for external power sources, batteries, or complex access equipment. The system cleans itself by utilizing the existing water supply infrastructure already present at the solar panel location.
Solution Approach 2:
The system employs a pressure-driven motor that converts hydraulic pressure from water supply into rotational torque to drive the cleaning mechanism. This hydraulic approach replaces complex mechanical access equipment with a simpler water-pressure-based propulsion and cleaning system.
2Reliability
If cleaning is performed during daytime in sunlight, then solar energy production is maintained, but thermal shock risks and electrical shock risks increase
Solution Approach 1:
The system operates autonomously using water pressure from the existing supply, eliminating need for external power sources that would pose electrical shock risks. The self-powered mechanism enables safe operation during nighttime or early morning hours when thermal shock risks are minimized.
Solution Approach 2:
The system changes the operational parameters by using water pressure (rather than electrical power) to drive the cleaning mechanism, enabling operation during times when panels are cooler and eliminating electrical shock hazards entirely.
3Productivity
If frequent cleaning is performed to maintain solar panel efficiency, then energy transformation effectiveness improves, but cleaning costs increase
Solution Approach 1:
The cleaning system utilizes the existing water supply infrastructure and converts water pressure into mechanical work, eliminating the need for external power sources, batteries, or complex access equipment. This self-powered approach dramatically reduces cleaning system costs while enabling frequent cleaning to maintain optimal solar panel efficiency.
Solution Approach 2:
By employing hydraulic pressure conversion to drive the cleaning mechanism, the system replaces expensive electrical motors and power supply infrastructure with a simpler, lower-cost water-pressure-based system that can operate frequently without significant additional cost.
