Slide rail assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies lack reliability in operation, particularly in maintaining the positioning of the aiding-slide member relative to the first rail, due to the integrally formed engaging hook and aiding-slide member being made of the same material, which fails to meet various operational requirements.
Innovation Solution
A slide rail assembly design where the auxiliary member and aiding-slide device are made of different materials, with the auxiliary member having an engaging feature that engages with a resilient portion of the retaining member to securely retain the aiding-slide device at a predetermined position, enhancing operational reliability through a combination of material properties and structural features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the engaging hook and aiding-slide member are integrally formed and made of the same material, then the manufacturing process is simplified, but the operational reliability is insufficient
Solution Approach 1:
The patent divides the previously integral engaging hook and aiding-slide member into separate components. The auxiliary member (engaging hook) is made of a first material while the aiding-slide device is made of a second material, allowing each component to be optimized independently for its specific functional requirements while maintaining manufacturing efficiency
Solution Approach 2:
The patent employs different materials for the auxiliary member and aiding-slide device. The auxiliary member uses a first material optimized for engaging features, while the aiding-slide device uses a second material suited for its sliding and positioning functions, thereby enhancing overall operational reliability through material properties matched to specific functional demands
2Device complexity
If the aiding-slide member is made of a single material, then the manufacturing complexity is reduced, but the ability to meet various operational requirements is limited
Solution Approach 1:
The patent segments the aiding-slide assembly into the auxiliary member and aiding-slide device as separate components with different materials. This segmentation allows each part to be manufactured with complexity appropriate to its function while the assembly as a whole meets diverse operational requirements
Solution Approach 2:
The patent applies different material properties to different parts of the assembly. The auxiliary member uses a first material with properties optimized for engaging and retaining, while the aiding-slide device uses a second material with properties optimized for sliding and positioning, allowing each local region to have the quality needed for its specific function
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
The design ensures reliable retention of the aiding-slide device at a predetermined position, preventing unintentional displacement and deformation, thereby improving the stability and smooth operation of the slide rail assembly.
Implementation Method 1
The retaining member includes a resilient portion, and the resilient portion includes a predetermined feature. The auxiliary member is made of a first material, and the aiding-slide device is made of a second material. When the second rail is detached from the channel of the first rail by displacing relative to the first rail along an opening direction, 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.
