Lighting Cover for Power-Receiving Connector with Angled Emission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting apparatuses for power-receiving connectors in vehicles face challenges in providing uniform illumination and decorativeness, as the bent or curved light emission face is difficult to recognize and maintain a uniform configuration, making it hard to use as an indicator for charging status and aesthetically pleasing.
Innovation Solution
A lighting apparatus with a light emission face that inclines from the cover top face towards the accommodation bottom face, featuring a first emission portion directed to the vehicular lower side and a second emission portion directed to the vehicular lateral side, with the first elevation angle being smaller than the second, allowing for improved visibility and decorativeness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the light emission face is bent or curved to irradiate over a wide range, then the illumination coverage is improved, but the visual recognition and decorativeness deteriorate due to non-uniform configuration
Solution Approach 1:
The light emission face is divided into multiple independent light emitting sections (first light emitting section and second light emitting section) with different elevation angles. This segmentation allows each section to be optimized for specific illumination directions while maintaining overall visual uniformity, resolving the contradiction between wide coverage and uniform appearance.
Solution Approach 2:
Different sections of the light emission face are assigned different local properties (elevation angles). The first light emitting section has a smaller elevation angle for downward illumination, while the second light emitting section has a larger elevation angle for lateral illumination. This local differentiation enables wide coverage while maintaining uniform visual configuration from the operator's perspective.
2Difficulty of detecting and measuring
If the light emission face is exposed to be visually recognizable, then the operator can recognize it, but the decorativeness deteriorates when bent or curved
Solution Approach 1:
The light emission face employs an asymmetric design with different elevation angles for different sections. This asymmetry creates a uniform visual configuration from the operator's viewpoint while maintaining decorativeness, avoiding the non-uniform appearance that would result from simple curvature.
Solution Approach 2:
The light emission face is designed with multi-dimensional angular variations (different elevation angles in different sections) rather than simple two-dimensional curvature. This dimensional approach enables uniform visual recognition while preserving aesthetic appearance.
3Device complexity
If the illumination light source is buried in the upper circumferential wall, then the structure is compact, but the light emission face cannot be visually recognized for indicator use
Solution Approach 1:
Instead of burying the light source in the upper wall as in conventional designs, the invention inverts the approach by positioning the light emission face on the lower side of the accommodation dent. This inversion makes the light emission face visible to operators while maintaining structural compactness.
Solution Approach 2:
The light emission face serves multiple functions: it provides illumination coverage and simultaneously acts as a visible indicator for charging status. This multi-functionality eliminates the need for separate indicator elements, maintaining structural compactness while achieving visibility.

AI summary
Disclosed is a lighting apparatus for power-receiving connector. The power-receiving connector includes a power-receiving accommodation chamber, and a power-receiving unit. The lighting apparatus is disposed on an accommodation bottom face in the power-receiving accommodation chamber, and includes a lighting cover. The lighting cover has a cover top face opposing the accommodation bottom face, and a cover side face disposed between the accommodation bottom face and the cover top face and inclining so as to overhang from the cover top face toward the accommodation bottom face. The cover side face includes a first emission portion directed to a vehicular lower side, and a second emission portion directed to a vehicular lateral side. A first elevation angle exhibited by the first emission portion to the accommodation bottom face is smaller than a second elevation angle exhibited by the second emission portion to the accommodation bottom face.
