Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display apparatuses face challenges in maintaining consistent optical distance between light sources and optical members, leading to issues with image quality uniformity, strength, and potential damage to optical components.
Innovation Solution
A light source apparatus is designed with a supporter that includes a supporter body with a curing device and an adhesive member. This setup maintains the optical distance by adhering the optical member to the supporter, ensuring stability and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a light source and optical member are directly mounted without a supporter structure, then the device complexity is reduced, but the optical distance between light source and optical member changes, leading to poor image quality uniformity
Solution Approach 1:
A supporter structure is introduced as an intermediary component between the light source and optical member. The supporter includes a supporter body with a curing device and adhesive member that maintains the optical member at a fixed position relative to the light source, ensuring consistent optical distance and preventing changes during operation.
2Strength
If adhesive member alone is used to fix optical member, then the device complexity is minimized, but the bonding strength is insufficient and optical member may be damaged
Solution Approach 1:
The curing device integrated in the supporter body emits light to cure the adhesive member in situ. This self-service mechanism allows the supporter structure to automatically strengthen its own bonding without requiring external curing equipment, thereby increasing bonding strength while minimizing additional device complexity.
3Manufacturing precision
If the optical member is loosely mounted to allow adjustment, then the ease of operation is improved, but the optical distance changes causing poor image quality uniformity
Solution Approach 1:
The adhesive member is applied in advance to the supporter body before mounting the optical member. The curing device then cures the adhesive to firmly fix the optical member at the predetermined position, preventing any subsequent movement or adjustment that would change the optical distance.
4Reliability
If no protective structure is provided for optical member, then the device complexity is reduced, but the optical member is vulnerable to damage
Solution Approach 1:
The supporter structure serves multiple functions simultaneously: it maintains the optical distance, provides mechanical support, protects the optical member from damage, and includes a curing device for bond strengthening. This multi-functionality increases reliability while minimizing the need for separate protective components.
