Symmetric Connector Cable for Bidirectional Signal Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connection methods require users to consider the direction of cable connections, which becomes complex as the number of units increases, necessitating either software or hardware switching of input and output ports.
Innovation Solution
A connection cable design featuring first and second connectors with concave and convex structures arranged in line symmetry, allowing for bidirectional compatibility without the need to distinguish between input and output ports, enabling flexible and simplified unit connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If daisy chain connection with directional ports is used, then signal transmission between units is achieved, but connection complexity increases as the number of units increases
Solution Approach 1:
The connector is designed with asymmetric concave and convex structures that are line-symmetric with respect to a reference line, creating a directional interface that naturally guides proper connection orientation while maintaining simple plug-and-play operation
Solution Approach 2:
The connection cable can function in multiple directions due to the line-symmetric design, allowing the same connector type to be used for both input and output connections without requiring different port types or switching mechanisms
2Reliability
If directional connection ports are used, then proper signal flow is ensured, but user operation becomes more difficult as direction awareness is required
Solution Approach 1:
The asymmetric concave-convex connector design provides visual and physical cues that guide users to connect in the correct orientation without requiring them to consciously determine input vs. output directions
Solution Approach 2:
The connector design itself provides the directional guidance function, eliminating the need for external labels, switches, or user knowledge about signal flow direction
3Adaptability or versatility
If input and output ports are switched to accommodate more units, then system expandability is achieved, but hardware or software switching complexity increases
Solution Approach 1:
The line-symmetric connector design allows the same physical interface to serve multiple functional roles (input and output) without requiring port switching, enabling seamless system expansion
Solution Approach 2:
Instead of switching ports to accommodate different connection scenarios, the design inverts the approach by making the connector itself adaptable to multiple directions through line-symmetric geometry
