Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies lack reliability in maintaining the aiding-slide device at a predetermined position due to integral materials with similar hardness, leading to potential deformation and operational instability.
Innovation Solution
The slide rail assembly features an auxiliary member with an engaging feature made of a harder material connected to an aiding-slide device of a softer material, along with a resilient retaining member, which includes a predetermined feature to securely retain the aiding-slide device at a position, enhanced by a restraining feature to prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the engaging hook and aiding-slide member are integrally formed made of the same material, then the manufacturing process is simplified, but the reliability and stability during operation deteriorates
Solution Approach 1:
The patent divides the integral structure into separate components: the auxiliary member (including engaging hook) and the aiding-slide member are manufactured separately from different materials and then assembled together. This segmentation allows each component to be optimized for its specific function while improving overall reliability.
Solution Approach 2:
The patent employs different materials for the auxiliary member and aiding-slide member based on their specific functional requirements. The auxiliary member uses material suitable for engaging features, while the aiding-slide member uses material optimized for sliding and bearing loads, creating a composite structure with superior operational reliability.
2Stability of the object's composition
If the aiding-slide device is retained at a predetermined position, then the stability during rail insertion is improved, but the device complexity increases due to additional retaining member
Solution Approach 1:
The retaining member is integrated with the first rail structure, merging the retention function into the existing rail design. The engaging feature on the auxiliary member works in conjunction with the retaining member to provide stable positioning without requiring a completely separate retention system.
Solution Approach 2:
The resilient portion of the retaining member automatically engages with the engaging feature to retain the aiding-slide device at the predetermined position during insertion, and then automatically disengages to allow easy removal. This self-activating mechanism provides stability during operation while maintaining ease of assembly and disassembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances the reliability of the aiding-slide device's retention at a position, ensuring stable and smooth operation by preventing deformation and damage, thus improving the overall functionality of the slide rail assembly.
Implementation Method 1
The resilient portion includes a predetermined feature. When the second rail is detached from the channel of the first rail by displacing relative to the first rail, the aiding-slide device is located at a predetermined position by an engagement of the engaging feature of the auxiliary member and the predetermined feature of the resilient portion of the retaining member.
Implementation Method 2
The resilient portion includes a predetermined feature... allowing easy disengagement without deformation or damage
