Cage Assembly Light Guide Post Hole Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cage assemblies with light guides suffer from insecure engagement of light guiding columns, leading to easy detachment and deformation, and limited installation positions due to insufficient volume for forming protruding pieces.
Innovation Solution
A cage assembly design featuring a cage, heat sink, clip, and light guide with specific post and hole configurations that provide multiple securing locations, ensuring firm engagement and adjustable assembly to prevent disengagement, and accommodating various light guide orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a recessed groove in fork shape is used to engage the light guiding column, then the structure is simple, but the engagement is insecure and the recessed groove deforms easily
Solution Approach 1:
The engagement structure is divided into multiple independent components: the light guiding column has a cylinder, the side plates have recessed grooves, and additional recessed grooves are added to the upper and lower plates. This segmentation distributes the engagement function across multiple locations, improving security while maintaining simplicity of each individual component.
Solution Approach 2:
The engagement mechanism merges multiple plates (upper plate, lower plate, two side plates) with integrated recessed grooves to work together as a unified constraint system. The light guiding column's cylinder is engaged by recessed grooves on all four plates simultaneously, creating a stable, multi-point constraint that prevents deformation and disengagement.
2Reliability
If a protruding piece is formed by punching the upper plate to secure the light guiding column, then the engagement is firm, but the installation position is limited due to insufficient volume
Solution Approach 1:
The engagement function is segmented from a single protruding piece on the upper plate and distributed to multiple recessed grooves located on the upper plate, lower plate, and side plates. This allows the light guiding column to be secured at multiple positions throughout the cage assembly, providing flexibility in installation while maintaining firm engagement.
Solution Approach 2:
The engagement mechanism transitions from a two-dimensional protruding piece on the upper plate to a three-dimensional distribution of recessed grooves across multiple plates and spatial locations. This enables the light guiding column to be constrained from multiple directions (front, rear, left, right), expanding installation flexibility while ensuring firm engagement.
3Reliability
If the light guiding column is engaged with multiple plates via recessed grooves, then the engagement security is improved, but the manufacturing complexity increases
Solution Approach 1:
The design uses standard punching and forming operations to create recessed grooves on all plates, maintaining consistent manufacturing parameters across components. By using the same basic processes (punching, forming) for all engagement features rather than introducing new complex operations, the manufacturing complexity is minimized while achieving secure multi-point engagement.
