Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wiper is used as a de-icing device, then it can remove snow from the solar panel, but the operation may be interrupted or the wiper may be damaged when the snow is frozen
Solution Approach 1:
The patent replaces the mechanical wiper system with an electrical system that applies reverse current to the solar panel. This electrical approach melts the snow and ice without the mechanical contact and wear issues that plague wiper-based systems, thereby eliminating the reliability problems associated with frozen snow damaging the wiper mechanism.
Solution Approach 2:
The patent changes the operating parameters by applying reverse current at specific voltage and current levels to melt the snow. By controlling the electrical parameters (voltage, current, duration) based on sensor feedback, the system achieves effective de-icing without the mechanical limitations of wiper-based approaches.
2Productivity
If a de-icing device is added to the solar panel system, then snow removal capability is improved, but the device complexity increases
Solution Approach 1:
The patent integrates multiple functions into a unified system: the sensor unit detects snow conditions, the control unit processes this information and determines when de-icing is needed, and the power supply unit applies reverse current. This multi-functional integration achieves effective snow removal while managing system complexity through coordinated operation of interconnected components.
Solution Approach 2:
The system incorporates sensors that automatically detect snow deposition and trigger the de-icing process without human intervention. The control unit autonomously monitors sensor data, determines when threshold conditions are met, and activates the reverse current application, enabling the system to service itself and eliminating the need for manual operation.
3Productivity
If reverse current is applied to melt snow, then de-icing effectiveness is improved, but energy consumption increases
Solution Approach 1:
The patent applies reverse current in periodic cycles rather than continuously. The control unit monitors sensor data and activates the power supply unit only when snow deposition is detected and threshold conditions are met. This periodic application of energy achieves effective de-icing while minimizing overall energy consumption compared to continuous operation.
Solution Approach 2:
The system incorporates sensor units that provide real-time feedback on snow conditions to the control unit. Based on this feedback, the control unit intelligently determines when to activate the reverse current application, adjusting the timing and duration of energy input to match actual de-icing needs, thereby optimizing energy efficiency while maintaining de-icing effectiveness.
