Two-Piece Slide Rail Fixing Assembly for Easy Coupling and Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixing parts for slide rails in mounting structures, such as dishwashers and ovens, require excessive force for coupling and separation, leading to deformation and increased manufacturing costs due to complex structures or high elastic forces.
Innovation Solution
A two-piece type fixing assembly with first and second fixing clips, where the first clip is laterally supported on a horizontal frame and the second clip is horizontally fixed, allowing for easy coupling and separation by applying an external force, utilizing a lever mechanism for efficient attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a fixing part with complex structure or high elastic force is used to improve fixing force, then the coupling force between fixing part and slide rail is improved, but excessive force and effort are required when separating the fixing part from the slide rail
Solution Approach 1:
The fixing part is divided into two separate clips (first fixing clip and second fixing clip) that work together. The first fixing clip provides strong coupling force through its bent portions engaging with the slide rail, while the second fixing clip provides a release mechanism with a pressing portion that applies localized force to detach the first fixing clip, thus reducing separation effort
Solution Approach 2:
The second fixing clip acts as an intermediary tool that facilitates the separation process. By pressing the pressing portion of the second fixing clip, force is applied to the first fixing clip to release its engagement with the slide rail, making separation easier without requiring excessive force directly on the first fixing clip
2Strength
If a fixing part with complex structure is used to maintain high coupling force, then the fixing force is improved, but manufacturing costs are increased
Solution Approach 1:
The fixing part is segmented into two simpler clips rather than one complex piece. Each clip has a specific function (first clip for coupling, second clip for release), which simplifies manufacturing of individual components while maintaining overall fixing strength through their cooperative structure
Solution Approach 2:
Each fixing clip is designed with specific structural features localized at critical positions (bent portions for engagement, pressing portion for release) while other areas remain simple. This allows complex functionality only where needed, reducing overall manufacturing complexity and cost
3Strength
If a fixing part with high elastic force is used to improve fixing force, then the coupling force is improved, but deformation of the fixing part occurs due to continuous movement
Solution Approach 1:
The fixing system uses two separate clips instead of one high-elastic-force component. The first fixing clip provides coupling force through its bent portions engaging with the slide rail, while the second fixing clip provides release capability, distributing the mechanical stress and reducing deformation risk
Solution Approach 2:
The fixing assembly allows dynamic engagement and disengagement through the coordinated action of two clips. The first clip engages statically for firm fixing, while the second clip enables dynamic release when needed, reducing continuous stress on a single elastic component
