Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If solar panels are installed in remote areas to maximize energy generation, then power generation capability is improved, but access for cleaning personnel and water sources becomes unavailable
Solution Approach 1:
The system enables solar panels to clean themselves through an automated mechanism. A robotic cleaning device traverses the panel surface, using onboard reservoirs to apply cleaning solution and embedded brushes or cloths to remove dirt, eliminating the need for human operators to access remote installations.
Solution Approach 2:
The patent introduces an automated cleaning robot as an intermediary between the solar panels and the cleaning function. This robot carries its own water reservoirs and cleaning mechanisms, serving as a self-contained intermediary that performs cleaning without requiring external water sources or human personnel.
2Ease of operation
If water is transported to remote solar panel locations for cleaning, then cleaning capability is improved, but system complexity and cost increase
Solution Approach 1:
The cleaning robot is designed as a multi-functional unit that combines water storage, cleaning solution application, and panel cleaning mechanisms in a single device. This universal unit performs all cleaning functions without requiring external water infrastructure, eliminating the need for separate water supply systems.
Solution Approach 2:
The patent embeds water reservoirs and cleaning mechanisms within the robotic structure itself. The cleaning components are nested within the robot body, allowing the entire cleaning system to be self-contained and portable without requiring external water sources or infrastructure.
3Reliability
If manual cleaning is performed by personnel, then cleaning effectiveness is improved, but safety risks and operational costs increase
Solution Approach 1:
The patent replaces the mechanical action of human personnel with an automated robotic system. The robot uses electrically-driven brushes, cloths, or spray mechanisms to clean the panels, substituting human mechanical cleaning with automated mechanical and fluid-based cleaning methods that eliminate safety risks.
Solution Approach 2:
The system performs cleaning autonomously without human intervention. The robot navigates the panel surface, applies cleaning solution from its reservoirs, and removes dirt automatically, enabling the solar panels to maintain themselves without exposing personnel to safety risks in remote or hazardous environments.
