Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing clamping devices are used for frameless glass-glass solar modules, then the solar modules can be fastened to support structures, but the force dissipation is not uniform and the assembly process becomes complex
Solution Approach 1:
The clamping device is divided into distinct functional segments: a U-shaped profile providing the receiving area, side wall sections for clamping, and attachment portions for fastening. This segmentation allows each component to perform its specific function optimally while simplifying the overall assembly process through modular construction.
Solution Approach 2:
The invention merges the receiving area formation and clamping functions into a single integrated U-shaped profile structure. The side wall sections and attachment portions are combined with the U-shaped profile to create a unified clamping device that ensures uniform force dissipation while reducing the number of separate components needed.
2Ease of manufacture
If existing clamping devices with elastic bodies are used, then the receiving area can be formed, but the production costs increase and the design becomes more complex
Solution Approach 1:
The invention extracts and eliminates the elastic body component from the clamping device design. Instead of using separate elastic elements, the U-shaped profile itself forms the receiving area through its geometric structure, thereby reducing part count, simplifying manufacturing, and lowering production costs while maintaining functional integrity.
Solution Approach 2:
The invention changes the structural parameters of the U-shaped profile to provide the necessary receiving area formation capability. By optimizing the geometry and dimensions of the profile, the device achieves both cost-effectiveness through simplified manufacturing and functional performance without requiring additional elastic components.
3Device complexity
If rigid clamping devices are used, then the structure is simple, but the force dissipation is not uniform across different support structures
Solution Approach 1:
The U-shaped profile with integrated side wall sections and attachment portions serves multiple functions simultaneously: it forms the receiving area, provides clamping action, and ensures uniform force dissipation across various support structure types. This multi-functionality is achieved through a relatively simple rigid structure that adapts to different mounting scenarios.
