Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional card sockets are used to mount two-layer card trays, then card mounting functionality is achieved, but the card socket occupies large space in the electronic device
Solution Approach 1:
The card socket is divided into two separate flexible circuit boards, each containing one card socket. This segmentation allows each socket to be independently optimized for smaller size while maintaining the overall two-card mounting functionality. The first flexible circuit board and second flexible circuit board can be arranged in different spatial configurations to minimize total space occupation.
Solution Approach 2:
The patent uses flexible circuit boards instead of traditional rigid card socket structures. The flexible nature of these circuit boards allows them to be made thinner and more compact, significantly reducing the volume occupied by the card socket assembly while maintaining structural integrity and electrical connection capabilities.
2Ease of manufacture
If traditional card socket structures are used, then card mounting is achieved, but manufacturing complexity and costs increase due to mold requirements
Solution Approach 1:
The patent changes the structural parameters of the card socket by adopting flexible circuit board technology. This parameter change transforms the manufacturing process from traditional mold-based rigid structure fabrication to flexible circuit board production, which simplifies manufacturing and reduces the need for complex molds while maintaining structural functionality.
3Volume of moving object
If card sockets are made thinner using flexible circuit boards, then space is reduced, but electrical connection reliability must be maintained
Solution Approach 1:
The flexible circuit boards are designed with appropriate thickness and structural reinforcement to maintain electrical connection reliability despite the reduced overall thickness. The flexible nature allows for controlled deformation while maintaining stable electrical contacts with the cards, ensuring reliable data and power transmission.
