Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic cables use similar connector designs for different protocols, then device compatibility and standardization are improved, but cable identification and distinction become difficult
Solution Approach 1:
The patent applies color-coding to the backshell of the connector assembly to enable easy identification of different cable types and protocols. Each cable protocol (HDMI, USB, Ethernet, etc.) is assigned a specific color, allowing users to quickly distinguish between different connectors without confusion, while maintaining standardized connector designs for device compatibility.
2Ease of operation
If connectors are positioned at the rear panel of electronic devices, then device design and cable management are improved, but visibility in low-light conditions deteriorates
Solution Approach 1:
The patent incorporates an LED light source within the connector assembly that illuminates the connector housing and surrounding area. This preliminary lighting action enables users to easily locate and connect cables to rear panel ports even in dark or low-light environments, maintaining good cable management while solving the visibility problem.
Solution Approach 2:
The patent introduces a translucent or transparent lens element as an intermediary between the LED light source and the external environment. This lens diffuses and directs the light to illuminate the connector housing and port area, enhancing visibility without requiring direct exposure of the light source, thereby improving both aesthetics and functionality.
3Adaptability or versatility
If multiple different cable types are used in an electronic system, then system functionality and connectivity are improved, but system complexity and connection confusion increase
Solution Approach 1:
The patent extends the color-coding system to the entire connector assembly including the backshell, providing a visual language that simplifies the selection and connection process. Users can quickly identify which cable type connects to which port based on color matching, reducing connection errors and simplifying system setup despite the presence of multiple cable types for different functionalities.
