Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If complex structured light bodies made of many materials are used, then lighting functionality is achieved, but manufacturing complexity and ecological footprint increase
Solution Approach 1:
The patent extracts and removes unnecessary complex structural elements from traditional light bodies. By using a simple frame structure made from a single material (cardboard or paperboard), the design eliminates multiple materials and complex assemblies, achieving easier manufacturing while maintaining lighting functionality through strategic placement of LED modules.
Solution Approach 2:
The patent applies homogeneity by constructing the entire light body frame from a single material type (cardboard or paperboard). This uniform material approach simplifies manufacturing processes, reduces material handling complexity, and improves ecological performance compared to multi-material constructions, while still achieving the required structural and functional goals.
2Adaptability or versatility
If cardboard material is used for the lamp frame, then ecological performance improves, but design options are limited to circular structures
Solution Approach 1:
The patent segments the light body into a modular frame structure made from cardboard or paperboard, which can be configured in various geometric patterns. This segmentation allows the same material to be used in different shapes (rectangular, square, triangular, etc.) and sizes, providing extensive design flexibility while maintaining ecological performance and simplifying manufacturing through standardized components.
3Strength
If traditional materials are used for light bodies, then structural strength is achieved, but ecological footprint increases
Solution Approach 1:
The patent changes the material parameter from traditional plastic or metal to cardboard or paperboard, which has significantly lower ecological footprint. By optimizing the frame geometry, thickness, and structural configuration, the design achieves adequate structural strength for supporting LED modules while using these eco-friendly materials, thus reducing harmful environmental factors without sacrificing necessary mechanical properties.
