Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If transparent materials (glass or acrylic) are used for the housing, then aesthetic appearance and user preference are improved, but electromagnetic interference shielding capability deteriorates
Solution Approach 1:
The patent combines transparent materials (glass or acrylic) with a conducting layer to create a composite housing structure. This composite material maintains the aesthetic transparency while adding electromagnetic shielding capability through the conductive layer deposited on the transparent surface.
Solution Approach 2:
The housing is designed to serve multiple functions simultaneously: it provides aesthetic appearance through transparency, electromagnetic interference shielding through the conducting layer, and structural protection. The conducting layer itself may also serve as a temperature sensing element, adding another functional dimension.
2Object-affected harmful factors
If a conducting layer is added to the transparent plate, then electromagnetic interference shielding is improved, but manufacturing complexity increases
Solution Approach 1:
The conducting layer is applied as a thin film on the transparent plate surface. This thin film approach maintains the transparency of the housing while providing effective electromagnetic shielding. The thin film can be deposited using standard coating techniques, making the manufacturing process manageable.
Solution Approach 2:
The electromagnetic shielding function is extracted as a separate conducting layer that can be independently applied to the transparent housing. This separation allows the shielding capability to be added without fundamentally changing the transparent material properties or requiring complete redesign of the housing structure.
