Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the optical structure of inverted-Fuji lighting devices is used, then uniform light distribution is achieved, but partial light loss occurs reducing luminous efficacy
Solution Approach 1:
The lighting device is divided into distinct functional modules: a light source module with LED array, a reflective module with reflective plate, and a transparent cover module. This segmentation allows optimization of each module's function - the reflective plate directs light while the transparent cover transmits it, reducing overall light loss while maintaining uniform distribution
Solution Approach 2:
A reflective plate is introduced as an intermediary element between the light source and the transparent cover. This reflective plate redirects light that would otherwise be lost, channeling it through the transparent cover to achieve both uniform distribution and reduced energy loss
2Stability of the object's composition
If the traditional installation structure is used, then structural stability is achieved, but installation process becomes complex increasing labor costs
Solution Approach 1:
The device is segmented into modular components (light source board, reflective plate, transparent cover) that can be independently manufactured and assembled. This modularity simplifies installation while maintaining structural stability through standardized connection interfaces
Solution Approach 2:
Multiple functional elements are merged into integrated assemblies - the light source board is combined with the reflective plate structure, and the transparent cover integrates mounting features. This merging reduces the number of separate installation steps while preserving structural integrity
