Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light emitting apparatuses face failures during handling and require improved manufacturing productivity, with a need for technologies that can enhance protection and simplify assembly processes.
Innovation Solution
A light emitting apparatus design featuring a base portion with a support surface, a light emitting element, and a cover portion with a light transmission portion and protrusion portions on its periphery, which are made of different materials or the same material integrally, to protect the light transmission portion and simplify manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light transmission portion is provided on the front end surface to guide light outside, then light extraction efficiency is improved, but the light transmission portion becomes vulnerable to damage during handling
Solution Approach 1:
The protrusion portion is provided in advance on the front end surface to protect the light transmission portion before any damage can occur during handling or mounting operations
Solution Approach 2:
The protrusion portion acts as a protective buffer that absorbs external forces and prevents direct contact with the vulnerable light transmission portion, cushioning it against potential damage
2Illumination intensity
If the light transmission portion is made prominent for effective light extraction, then light transmission performance is improved, but the apparatus becomes more susceptible to failures during conveying and mounting
Solution Approach 1:
The protrusion portion is pre-configured on the front end surface to protect the light transmission portion before handling operations begin
Solution Approach 2:
The protrusion portion serves as an intermediary protective element between external forces and the light transmission portion, shielding it from harmful effects during handling
3Reliability
If a protective structure is added to the light transmission portion, then damage resistance is improved, but manufacturing complexity and assembly steps increase
Solution Approach 1:
The protrusion portion is integrated with the front end surface as a unified structure, eliminating the need for separate protective components and reducing assembly steps
Solution Approach 2:
The front end surface serves multiple functions: light transmission and structural protection, eliminating the need for dedicated protective components
