Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If connectors are reduced in size and height, then weight and device compactness are improved, but impedance increases and signal transmission characteristics deteriorate
Solution Approach 1:
The patent applies local quality by differentiating the material properties of different connector components. Specifically, the first contact and second contact are made from materials with different elastic moduli, creating localized mechanical property variations that optimize both signal transmission and structural integrity in the compact connector design
Solution Approach 2:
The patent changes physical parameters by controlling the elastic deformation characteristics of contacts through material selection. By selecting materials with specific elastic modulus ratios, the design achieves optimal impedance control and signal transmission in the reduced-size connector while maintaining reliable electrical connection
2Volume of moving object
If connectors are reduced in size and height, then device compactness is improved, but structural strength and reliability deteriorate
Solution Approach 1:
The patent applies local quality by assigning different material properties to specific connector components based on their functional requirements. The first contact and second contact use materials with differentiated elastic moduli, optimizing both mechanical strength and electrical performance in the compact connector structure
Solution Approach 2:
The patent employs composite material strategy by combining materials with different elastic moduli in the contact structures. This composite approach allows the connector to achieve both reduced size and maintained structural strength through optimized material distribution and mechanical property differentiation

AI summary
According to the present disclosure, a connector module 1 includes first and second connectors 50 and 10 that are configured to engage each other. The first connector 50 includes a first insulator 60 and first contacts 70 each of which includes a first free end 75 positioned opposite to a first mount portion 71. The second connector 10 includes a second insulator 20 and second contacts 30 each of which includes a second free end 36 positioned opposite to a second mount portion 31. In a state of engagement, the first and second contacts 70 and 30 are in contact with each other on one side of the first sidewall 62b and separated from each other on the other side, the one side being closer to a center of the first connector 50, and the first and second free ends 75 and 36 are positioned on the one side.
