Curved Surface Light Source Fixing Fixture Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light-emitting devices with flexible surface light sources require significant worker effort to maintain a curved shape during fixation, as they need to position and insert tabs into slits on a support member, leading to a high workload.
Innovation Solution
A light-emitting device design featuring a surface light source with first and second fixtures, each having curved surfaces and positioning ribs, allowing the surface light source to be mounted flat and then curved between the fixtures, reducing the need for manual alignment and insertion of tabs, thus lowering the worker's workload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the surface light source is fixed using tabs and slits on a support member, then the curved shape can be maintained, but the worker's workload increases significantly
Solution Approach 1:
The patent introduces a dedicated curving fixture as an intermediary tool between the worker and the surface light source. This fixture includes a curving surface that matches the desired curved shape, positioning ribs for precise tab placement, and clamping mechanisms. The fixture automates the curving and fixation process, eliminating the need for workers to manually maintain the curved shape while positioning tabs into slits, thus resolving the contradiction between shape maintenance reliability and ease of operation.
2Manufacturing precision
If manual alignment and insertion of tabs into slits is required, then the surface light source can be fixed in position, but the complexity of the fixation process increases
Solution Approach 1:
The fixture is designed with pre-configured positioning ribs that have predetermined positions and orientations matching the required tab placements. The curving surface is pre-formed to the exact desired curvature. When the surface light source is placed on the fixture, the tabs automatically align with the positioning ribs, and the curving surface automatically assumes the correct shape. This preliminary configuration eliminates the need for complex manual alignment operations during fixation, reducing process complexity while maintaining high positioning accuracy.

AI summary
Provided are a light-emitting device and a method of manufacturing the same. The light-emitting device includes a flexible surface light source curved in a desired shape, a first fixture that includes first and second positioning ribs, and has a first curved surface between the first and second positioning ribs, and a second fixture having a second curved surface. The method includes mounting the surface light source in a flat state on the first positioning rib and the second positioning rib such that the front or rear surface and the first curved surface face to each other across a space, bringing the second fixture close to the first fixture and pushing the surface light source toward the first fixture to curve the surface light source, and fixing the first and second fixtures together with the curved surface light source held therebetween.
