Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If separate shielding members are used to shield electromagnetic noise, then shielding effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent combines the shielding function with the cable insulation film itself, making the insulation film serve dual purposes: electrical insulation and electromagnetic noise shielding. This is achieved by forming a ground electrode pattern on the insulation film, integrating the shielding function into the existing structural component rather than adding separate shielding members.
Solution Approach 2:
The insulation film is designed to perform multiple functions simultaneously: providing electrical insulation between cables and the substrate, and providing electromagnetic noise shielding through the integrated ground electrode pattern. This multi-functionality eliminates the need for separate shielding components.
2Device complexity
If cables are directly connected to electrodes without additional shielding, then device complexity is reduced, but signal interference increases
Solution Approach 1:
The patent introduces a ground electrode pattern formed on the insulation film as an intermediary between the cables and the substrate. This ground pattern acts as a mediator that provides electromagnetic shielding without requiring direct contact between cables and the substrate, thereby reducing signal interference while maintaining structural simplicity.
3Reliability
If the insulation film is made thick to prevent damage, then reliability is improved, but flexibility and ease of connection deteriorate
Solution Approach 1:
The patent uses a composite structure consisting of the insulation film with an integrated ground electrode pattern. This composite design provides enhanced protection and shielding functionality without significantly increasing the overall thickness, maintaining the flexibility needed for easy connection and positioning.
