Charging Socket Light Guide for Status Display Without Glare
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging sockets lack aesthetic appeal and fail to effectively display charging status, and their lighting can cause visual discomfort in dark environments, leading to potential mis-operations and safety hazards.
Innovation Solution
A charging socket with a light guide device featuring a transparent panel, light source, and light guide elements made of transparent plastic, allowing for colorful displays and improved lighting effects through a light guide device that integrates with a PCB board and status indicator lamps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a traditional charging socket design is used, then the structure is simple, but the aesthetic appeal and user experience are insufficient
Solution Approach 1:
The patent combines the light guide device with the charging socket housing structure, integrating the lighting function into the existing design. The transparent panel is incorporated into the front housing, and the light guide columns are positioned within the housing structure, merging multiple functions (aesthetic display, status indication, lighting) into a unified design that enhances appearance without proportionally increasing complexity
Solution Approach 2:
The charging socket is designed with multi-functionality by incorporating a light guide device that serves multiple purposes: aesthetic illumination, charging status display through different colored lights, and user guidance. The transparent panel both protects internal components and serves as a display medium, while the light guide structure provides both decorative lighting and functional status indication
2Loss of information
If no light guide device is used, then the structure is simpler, but the charging status cannot be displayed
Solution Approach 1:
The light guide device acts as an intermediary between the charging status information and the user. The status indicator lamps generate light information about charging status, and the light guide columns and transparent panel transmit and display this information visually. This intermediary structure enables effective status communication without requiring complex electronic displays or additional components
Solution Approach 2:
The patent uses color changes of light to convey different charging status information. Status indicator lamps emit different colored lights (e.g., green for charging, red for full, yellow for fault) that are transmitted through the light guide columns and transparent panel, providing intuitive visual feedback to users about the charging state without requiring text or symbolic displays
3Illumination intensity
If a bright lamp is used for lighting, then the lighting effect is better, but local blind areas appear in user vision causing mis-operations
Solution Approach 1:
The light guide device implements local quality by directing light to specific areas through the transparent panel and light guide columns. The lighting is distributed across multiple points rather than concentrated in one bright source, providing adequate illumination for viewing the charging socket and status indicators without creating blinding hot spots. The light intensity is optimized for local visibility needs rather than overall brightness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the aesthetic appeal of charging sockets, provides clear charging status indicators, and ensures safe lighting conditions, improving user experience and safety by allowing users to easily determine charging status through color-coded displays.
Implementation Method 1
the transparent panel is made of transparent plastic, and the transparent panel is capable of guiding the light inside the charging socket housing to the outside thereof
Implementation Method 2
the light guide device includes a light guide column and a light guide plate; the light guide plate is attached to or close to the transparent panel, two ends of the light guide plate extend downward to form the light guide column, and a tail end of the light guide column is attached to or close to the status indicator lamp
