Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional insulation devices and snow removal equipment are used to protect solar cells in cold areas, then the solar cell can operate normally under extreme cold conditions, but the overall system cost increases significantly
Solution Approach 1:
The patent combines the heating function with the solar cell module by integrating a heating film directly into the module structure. The heating film is bonded between the back plate and the first transparent adhesive layer, merging the protective heating function with the power generation function in a single integrated unit, thereby reducing system complexity and cost.
Solution Approach 2:
The solar cell module is designed to serve multiple functions: power generation through solar cells and ice/snow removal through the integrated heating film. This multi-functional design eliminates the need for separate insulation devices and snow removal equipment, reducing overall system complexity while maintaining reliability in cold conditions.
2Productivity
If heating systems are added to maintain solar cell temperature in cold areas, then power generation efficiency is improved, but the cost-effectiveness decreases due to additional expenses
Solution Approach 1:
The heating function is merged into the solar cell module itself through the integrated heating film, eliminating the need for separate heating systems. This integration reduces system cost while maintaining the ability to improve power generation efficiency through temperature control in cold conditions.
Solution Approach 2:
The solar cell module serves itself by generating heat through the integrated heating film to remove ice and snow from its surface. This self-service capability eliminates the need for external heating systems, reducing system cost while maintaining power generation efficiency in cold environments.
3Reliability
If electric energy from solar cells is used to maintain surrounding temperature, then solar cell performance is maintained, but the overall power generation efficiency is reduced due to energy consumption
Solution Approach 1:
The heating film is applied locally only to the solar cell module surface where ice and snow removal is needed, rather than heating the entire surrounding area. This localized heating approach maintains solar cell performance while minimizing energy consumption and maximizing overall power generation efficiency.
Solution Approach 2:
The heating system provides just enough heat to remove ice and snow from the solar cell surface and maintain optimal operating temperature, rather than excessively heating the surrounding environment. This partial action approach maintains performance while reducing energy loss.
