Illuminated EV Charging Connector Using a Translucent Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging station connectors are difficult to locate in dark environments, as existing solutions often rely on external lighting or localized indicators, which may not be sufficient for clear visibility.
Innovation Solution
A charging station with a translucent connector area that directs light from an integrated light source, such as an LED, to illuminate the connector, ensuring visibility even in low-light conditions, and potentially using light pipes for precise light direction and a semi-translucent material for even light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light source is connected to the connector of the charging station, then the connector becomes visible in dark environments, but the device complexity increases
Solution Approach 1:
The patent merges the light source integration directly into the connector housing structure. The connector is designed with an integrated light guide or illumination chamber that incorporates the light source, eliminating the need for separate external lighting components. This merging approach provides effective illumination while minimizing additional device complexity by combining functions into a single integrated component.
Solution Approach 2:
The connector serves multiple functions: electrical connection, mechanical coupling, and visual indication through integrated illumination. By making the connector multi-functional, the patent eliminates the need for separate indicator lights or external lighting devices, thereby reducing overall device complexity while maintaining effective visibility in dark environments.
2Illumination intensity
If external lighting or localized indicators are used to indicate the charging station location, then the connector becomes visible, but the solution becomes complex and costly
Solution Approach 1:
The illumination function is merged into the connector itself rather than being a separate component. This integration reduces the total parts count, simplifies assembly procedures, and lowers manufacturing costs by eliminating the need for separate mounting brackets, wiring harnesses, and control circuits for external lighting devices.
Solution Approach 2:
The connector illuminates itself through integrated lighting elements that are part of its structure. This self-service approach eliminates the need for external power supplies, control systems, and installation infrastructure, thereby reducing both manufacturing costs and installation complexity while providing effective visibility.
