Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional conductive structures are used to transmit electrical signals from module to host, then signal transmission is achieved, but device complexity increases
Solution Approach 1:
The patent merges the signal transmission function into the existing mechanical connection structure. The connection terminals are integrated into the connector that already mechanically couples the module to the host, eliminating the need for separate conductive structures. This is achieved by incorporating contact elements directly into the connector body, so that a single component performs both mechanical support and electrical signal transmission functions.
2Reliability
If additional conductive structures are used to transmit electrical signals from module to host, then signal transmission is achieved, but manufacturing costs increase
Solution Approach 1:
The patent combines multiple functions into a single connector component, reducing the total part count and assembly steps. By integrating signal transmission capabilities into the existing mechanical connector, the design eliminates separate conductive structures, thereby reducing manufacturing complexity and cost while maintaining reliable electrical connection.
Solution Approach 2:
The connector is designed to perform multiple functions simultaneously: mechanical coupling, structural support, and electrical signal transmission. This multi-functional design reduces the need for additional specialized components, simplifying the bill of materials and reducing overall manufacturing costs while ensuring reliable signal transmission.
3Ease of repair
If modular input components are used, then ease of replacement is improved, but connection complexity increases
Solution Approach 1:
The patent divides the input device into modular components that can be independently replaced. The connector is designed with standardized interfaces that allow individual modules to be detached and reattached without affecting other parts of the system. This segmentation enables easy replacement while keeping each module's connection interface simple and standardized.
