Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If electromagnetic radiation shielding is implemented using traditional materials, then radiation protection is improved, but device weight and bulk increase
Solution Approach 1:
The patent employs a composite material structure consisting of multiple layers with distinct functions: a conductive layer (silver or copper foil) for electromagnetic shielding, a porous foam layer for absorption and mechanical cushioning, and an adhesive layer for bonding. This composite structure achieves effective radiation protection while maintaining lightweight properties, as each layer contributes specific properties that collectively solve the contradiction between shielding effectiveness and weight.
2Object-affected harmful factors
If traditional electromagnetic shielding materials are used, then radiation protection is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The shielding device is segmented into multiple functional layers: a conductive layer for reflection and shielding, a porous foam layer for absorption and mechanical protection, and an adhesive layer for bonding. This segmentation allows each layer to perform its specific function optimally while simplifying the overall manufacturing process, as each layer can be independently produced and then assembled through lamination.
3Object-affected harmful factors
If conductive materials are used for electromagnetic shielding, then radiation protection is improved, but corrosion resistance deteriorates
Solution Approach 1:
The patent uses a composite structure where the conductive layer (silver or copper foil) is combined with a porous foam layer and an adhesive layer. The adhesive layer acts as a protective barrier that prevents direct exposure of the conductive material to corrosive environments, while the porous foam layer provides additional mechanical protection. This composite approach maintains the electromagnetic shielding effectiveness of the conductive material while significantly improving its corrosion resistance.
