Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a metal piece and plastic piece insertion device is added to improve mechanical stability, then insertion stability is improved, but electromagnetic wave protection becomes insufficient
Solution Approach 1:
The invention combines the insertion device structure with electromagnetic shielding functionality by integrating a conductive shielding layer onto the plastic piece and establishing electrical connection between the metal piece and ground. This merging allows the same component to provide both mechanical insertion stability and electromagnetic wave protection simultaneously.
Solution Approach 2:
The insertion device uses composite construction with metal piece (conductive) and plastic piece (insulating), enhanced with a conductive shielding layer. This composite material approach allows different parts to serve different functions: metal for mechanical strength and EMI shielding, plastic for insulation and structural support, and conductive layer for enhanced electromagnetic protection.
2Adaptability or versatility
If the connector structure is made thickness-adjustable, then adaptability to different insertion slots is improved, but device complexity increases
Solution Approach 1:
The insertion device incorporates a resilient portion that can elastically deform to accommodate different thickness requirements. This dynamic property allows the rigid metal piece and plastic piece assembly to adapt to varying insertion slot dimensions while maintaining structural integrity and electrical connection.
Solution Approach 2:
The invention allows adjustment of the insertion device thickness by modifying the dimensions of the metal piece, plastic piece, or resilient portion. By changing these physical parameters, the same basic structure can be adapted to match different insertion slot sizes without requiring completely different designs.

Implementation Method 1
The insulation layer has a surface, which forms, in at least a portion thereof, a conductive shielding layer that is electrically connectable to a grounding path. The conductive shielding layer extends to the insertion device mounting section, so as to provide electromagnetic wave protection with the metal member of the insertion device and the conductive shielding layer

AI summary
Disclosed is a structure of electromagnetic wave resistant connector for flexible flat cable. A flexible flat cable defines an insertion device mounting section to which an insertion device is mounted. The insertion device includes a metal member that is at least partly formed of a metal material. The flexible flat cable forms thereon conductive traces on which an insulation layer is provided. The insulation layer has a surface, which forms, in at least a portion thereof, a conductive shielding layer. The conductive shielding layer extends to the insertion device mounting section, so that when the insertion device is mounted to the insertion device mounting section, electrical connection is formed between the metal member of the insertion device and the conductive shielding layer.
