Lighting Panel Structure for End-Face Visibility at Oblique Angles

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The visibility of a lighting device is obstructed by an in-line portion positioned in line with the lighting device, making it difficult to see from certain angles.

Innovation Solution

The lighting device is disposed along a first face of the apparatus, with an in-line portion that includes an exposing portion formed contiguously from one-end to the other-end, and an inclined face on the in-line portion to expose the end face of the lighting device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If an in-line portion is positioned in line with the lighting device, then the structural integration is improved, but the visibility of the lighting device deteriorates

Engineering Contradiction:

Improvestructural integrationVSAvoidvisibility of lighting device

Core Design Contradiction:

Stability of the object's compositionVSDifficulty of detecting and measuring

Solution Approach 1:

The in-line portion is segmented into multiple regions: a first region that covers part of the lighting device and a second region that exposes another part of the lighting device. This segmentation allows the structure to maintain integration while providing visibility through the exposing portion.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the in-line portion have different properties: the first region provides coverage for structural integration, while the second region (exposing portion) provides transparency or openness for visibility. This local differentiation resolves the contradiction between integration and visibility.

Inventive Principle:

Principle #3Local quality

2Volume of moving object

If the lighting device is disposed along the first face, then the space utilization is improved, but the visibility from diagonal directions deteriorates

Engineering Contradiction:

Improvespace utilizationVSAvoidvisibility from diagonal directions

Core Design Contradiction:

Volume of moving objectVSDifficulty of detecting and measuring

Solution Approach 1:

The solution addresses visibility from diagonal directions by creating an exposing portion that extends in a direction perpendicular to the main face, allowing light from the lighting device to be visible from multiple angles and dimensions, not just from the front face.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If the exposing portion is formed intermittently, then the manufacturing complexity is reduced, but the visibility of the lighting device deteriorates

Engineering Contradiction:

Improvemanufacturing complexityVSAvoidvisibility of lighting device

Core Design Contradiction:

Ease of manufactureVSDifficulty of detecting and measuring

Solution Approach 1:

The exposing portion is formed contiguously from one end to the other end of the in-line portion, providing continuous visibility of the lighting device. This continuous exposing portion maintains ease of manufacture while ensuring unobstructed visibility, avoiding the need for multiple separate exposing regions.

Inventive Principle:

Principle #20Continuity of useful action
