Light Guide Holder With Elastic Clamping for Adhesive-Free Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of elongated light guide fibers, such as optical fibers, is tedious and complicated due to their flexibility, often resulting in a wavy appearance, and positioning them close to a transparent plate for optimal lighting effects is challenging without adhesive use.
Innovation Solution
A holding device with a first holding body part featuring an elongated depression and a second elastically deformable part allows for mechanical mounting of the light guide fiber by expanding the opening to insert and clamp it securely, using different plastics for the parts to ensure stability and ease of installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is used to position light guide fibers close to a transparent plate, then positioning stability and lighting effect are improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent replaces the adhesive chemical bonding system with a mechanical clamping system. The holding device uses a elastically deformable second holding body part that can be expanded to clamp the light guide fiber securely against the transparent plate, eliminating the need for adhesives while maintaining positioning stability and avoiding the complexity of adhesive application and curing processes.
Solution Approach 2:
The patent utilizes elastic deformation as a reversible parameter change mechanism. The second holding body part is designed to deform elastically under expansion force, allowing the opening to widen for fiber insertion, then return to its original shape to clamp the fiber securely. This parameter change approach provides stable positioning without requiring additional bonding materials.
2Ease of operation
If light guide fibers are installed manually without assistance, then installation simplicity is maintained, but installation time and labor complexity increase
Solution Approach 1:
The holding device is pre-configured with the light guide receiver and elastically deformable clamping mechanism in place before fiber installation. This preliminary preparation allows the fiber to be simply inserted into the pre-formed recess, eliminating the need for complex manual positioning and securing operations during installation.
Solution Approach 2:
The elastically deformable second holding body part performs the clamping action automatically after fiber insertion. When the holding device is pressed against the transparent plate, the elastic deformation mechanism self-adjusts to clamp the fiber securely, eliminating the need for additional manual clamping operations or complex installation procedures.
3Reliability
If a rigid holding structure is used to secure light guide fibers, then positioning stability is improved, but ease of installation and adaptability decrease
Solution Approach 1:
The patent employs a dynamic, elastically deformable second holding body part instead of a static rigid structure. This dynamic component can expand and contract in response to applied forces, allowing easy fiber insertion when expanded, then providing secure clamping when returned to its original shape, thus combining installation ease with positioning stability.
Solution Approach 2:
The elastic deformation capability allows the holding structure to change its physical parameters (opening width) in response to installation conditions. The material and geometry are designed to deform elastically under expansion force for easy fiber insertion, then return to maintain stable positioning, thus adapting to different installation scenarios while ensuring reliability.

Function Achieved in This Case
The solution provides a cost-effective, stable, and simple method to position light guide fibers close to a transparent plate without adhesives, ensuring reliable clamping and preventing wavy installation issues.
Implementation Method 1
the second holding body part is configured such that it is elastically deformable by the application of an external force, and the second holding body part is connected to the first holding body part such that, by an elastic deformation of the second holding body part, the width of the opening with respect to the basic shape of the holding body, in which no external force acts, is increased
Implementation Method 2
after removal of the external force, the holding body essentially returns to its basic form, so that the enclosing sections enclose the light guide body inserted into the depression, and the light guide body is clamped by the enclosing sections

AI summary
A holding device for a light guide body includes a holding body that includes a light guide receiver and that is formed from a first holding body part and a second holding body part. The light guide receiver is formed as a depression which is delimited on opposite sides by two enclosing sections of the first holding body part. The second holding body part is connected to the first holding body part such that, by an elastic deformation of the second holding body part, a width of an opening is increased by spreading apart the two enclosing sections so that the light guide body can be inserted into the light guide receiver. After removal of the deformation force, the holding body returns to its basic shape, whereby the enclosing sections enclose the light guide body inserted into the depression, and the light guide body is clamped by the enclosing sections.
