Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the connector is assembled within the limited internal space of the electronic device, then the device achieves compactness, but the design flexibility of terminal layout is reduced
Solution Approach 1:
The connector is divided into a shell and a terminal assembly that can be assembled separately. The terminal assembly includes terminals mounted on an insulating substrate, which can be pre-assembled and then integrated into the shell, allowing flexible terminal layout design within compact space constraints.
Solution Approach 2:
The connector utilizes three-dimensional space utilization by extending terminals in multiple directions from the insulating substrate, and positioning the terminal assembly within the shell cavity. This dimensional arrangement allows optimized terminal layout while maintaining compact overall dimensions.
2Volume of moving object
If the interval between adjacent connectors is shortened to save space, then device compactness is improved, but electromagnetic interference and crosstalk between connectors increase
Solution Approach 1:
A conductive shielding plate is introduced as an intermediary element between adjacent connectors or between terminal groups. This shielding plate is electrically connected to ground and positioned within the shell to block electromagnetic fields, reducing interference and crosstalk while allowing closer connector spacing.
Solution Approach 2:
The shell incorporates conductive shielding structures that can be configured as thin plates or partitions within the connector housing. These shielding elements flexibly adapt to the compact layout while providing electromagnetic isolation between adjacent signal paths.
3Ease of manufacture
If the connector structure is simplified to ease assembly in limited space, then assembly process is improved, but electromagnetic shielding and grounding effectiveness may be reduced
Solution Approach 1:
The shell integrates multiple functions: mechanical protection, electromagnetic shielding, and grounding. The conductive shell body serves as both the protective housing and the shielding/grounding structure, eliminating the need for separate shielding components and simplifying assembly while maintaining electromagnetic protection effectiveness.
Solution Approach 2:
The conductive shell performs multiple roles simultaneously: structural support, electromagnetic shielding, and electrical grounding. This multi-functionality reduces the number of components and assembly steps while ensuring reliable electromagnetic interference protection in the compact connector design.
