Illuminated Cable Connector Lens for Low-Light Cable Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of electronic systems with multiple interconnected devices leads to confusion in distinguishing and identifying electronic signal cables, especially in low-light conditions due to similar types like HDMI connections, which are difficult to discern without adequate illumination.
Innovation Solution
Electronic signal cables are designed with a light-emitting diode within the connector backshell that illuminates a translucent or transparent lens, color-coding the cables and illuminating the connectors, using monochromatic or white LEDs with tinted lenses to differentiate between different types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic signal cables of the same type are used to connect various devices, then the electronic system becomes more functional and versatile, but it becomes difficult to distinguish and identify individual cables, especially in low-light conditions
Solution Approach 1:
The patent applies color-coding to the lens surrounding the LED indicator on each cable connector. Different cable types or functions are associated with different lens colors, enabling visual differentiation and easy identification of cables in low-light conditions without affecting the cable's electrical functionality.
Solution Approach 2:
The patent incorporates an LED indicator that can illuminate the lens to provide active visual signaling. This dynamic illumination helps distinguish cables and their connection status in dark environments, complementing the static color-coding scheme.
2Reliability
If electronic signal cables are connected at the rear panel of electronic devices where lighting is minimal, then the connections are made securely, but the connectors become difficult to see and identify
Solution Approach 1:
The LED indicator integrated into the connector assembly provides active illumination of the lens, making the connector visible in low-light rear panel areas. The LED can be energized to highlight the connector position and type, solving the visibility problem without compromising connection security.
Solution Approach 2:
The colored lens provides passive visual identification of connector types even in dark environments. The color coding allows users to quickly identify connector types and cable functions without requiring additional lighting, while the connector maintains its secure mating capability.
