Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple harnesses are used to connect substrates in different planes, then electrical connection between substrates is achieved, but electromagnetic interference increases and device complexity increases
Solution Approach 1:
The patent combines multiple separate harnesses into a single integrated connector that connects both substrates simultaneously. This merging of connection functions reduces the number of separate electrical pathways, thereby minimizing electromagnetic interference while maintaining reliable electrical connection between substrates in different planes.
Solution Approach 2:
The connector is designed as a universal component that can connect multiple substrates in different orientations and planes through a single device. This multi-functional connector eliminates the need for separate harnesses for each substrate connection, reducing overall device complexity and electromagnetic interference.
2Reliability
If multiple harnesses are used to connect substrates, then electrical connection is provided, but device complexity and cost increase
Solution Approach 1:
The patent integrates multiple connection functions into a single connector assembly, combining what would otherwise require multiple separate harnesses. This consolidation simplifies the overall device structure, reduces the number of components, and lowers manufacturing complexity while ensuring reliable electrical connections.
3Adaptability or versatility
If substrates are positioned in different configurations, then spatial constraints are satisfied, but connection reliability decreases with conventional bonding techniques
Solution Approach 1:
The connector incorporates elastic elements that can dynamically adapt to different substrate positions and orientations. These elastic components deform to accommodate varying configurations while maintaining consistent electrical contact, ensuring connection reliability across multiple substrate arrangements without requiring precise positioning.
Solution Approach 2:
The connector design allows for changes in physical parameters such as elastic deformation and contact force to accommodate different substrate configurations. By varying these parameters, the connector maintains reliable electrical connection whether substrates are parallel, angled, or in other relative positions.
