Shell Accessory Optical Element Mounting for Uniform Beam Angles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for creating shell-like accessories, such as large dolls, result in non-uniform light emission due to uneven adhesive distribution and deformation of the structure, leading to uncontrolled light beam angles and brightness variations.
Innovation Solution
The use of transfer units with adjustable angles and a specific design featuring pitched fins, an adhesive tank, and a dry combination method allows for precise alignment and stabilization of laser elements, ensuring parallel light beams and uniform lumen distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fiber sheets are glued by hand to form the housing, then the shell-like accessory can be manufactured, but the adhesive agent deforms the structure surface and causes non-uniform light beam angles
Solution Approach 1:
The housing formation process is segmented into multiple stages: first forming the housing without the implant area, then separately creating the implant area with precise structural surfaces, and finally combining them. This segmentation allows the critical implant area to be manufactured with high precision while the overall housing can still be produced through hand-gluing fiber sheets.
Solution Approach 2:
The implant area is prepared in advance with pre-formed precise structural surfaces before being combined with the main housing. By performing the precision manufacturing of the implant area beforehand, the patent ensures that the laser element mounting surface has the required accuracy without compromising the ease of overall housing manufacture.
2Shape
If the implant area is directly planned on the housing, then the accessory appearance is matched, but the center lines of laser elements offset and brightness becomes non-uniform
Solution Approach 1:
The patent introduces a specialized implant area structure that acts as an intermediary between the housing and laser elements. This implant area includes precise structural surfaces and positioning features that serve as a mediator, ensuring both appearance matching with the overall accessory shape and precise control of laser element orientations through dedicated positioning holes and reference surfaces.
Solution Approach 2:
The implant area is designed with local precision features specifically where needed - the structural surfaces and positioning holes in the implant area have high precision requirements, while other parts of the housing can maintain lower precision. This local quality approach allows appearance matching overall while ensuring precise light beam angles at the critical illuminating area.
3Strength
If adhesive agent is used to combine the implant area, then the components can be joined, but the adhesive deformation causes uncontrolled projected angles of light beams
Solution Approach 1:
The patent extracts the critical positioning and alignment functions from the adhesive bonding process. By providing dedicated positioning holes, reference surfaces, and mechanical interlocking features in the implant area, the patent removes the responsibility of angle control from the adhesive agent, leaving the adhesive to perform only its primary function of providing bonding strength.
Solution Approach 2:
The positioning holes and reference surfaces are prepared in advance during implant area manufacturing, before the adhesive bonding step. This preliminary action ensures that when laser elements are mounted, their positions and angles are predetermined by the mechanical features rather than being dependent on adhesive application accuracy.
4Illumination intensity
If multiple laser elements are distributed on the illuminating area, then the light decoration effect is achieved, but the non-uniform radiation angle creates brightness variations
Solution Approach 1:
The implant area is designed with locally optimized precision features - each positioning hole and reference surface is specifically configured to control the orientation of individual laser elements. This local precision approach ensures that despite multiple laser elements being distributed across the illuminating area, each element radiates light at the correct angle, achieving both bright decoration effect and uniform brightness distribution.

AI summary
An adapting type of optical element in a shell-like accessory is disclosed. For a shell-like accessory formed by gluing fiber threads, an illuminating area is planned on the surface of shell-like accessory to develop lumen by combining laser elements to the illuminating area. The combination is implemented by adapting a transfer unit with a pitched fin to form a transient pinching. The transfer unit is implanted in advance in an implant area of the illuminating area. During implantation and combination, by the pinching and supporting of the pitched fins of the transfer units, angles of center lines of the transfer units can be adjusted, so that accurate projected angles of light beams from the post-adapted laser elements can be achieved.
