Slide rail assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail assemblies lack an efficient mechanism to retract a rail from an extended position relative to another rail, limiting their versatility and functionality.
Innovation Solution
A slide rail assembly with a blocking member and an operating member that allows the second rail to be retracted from an extended position by releasing the positioning member from the stop wall of the blocking member, utilizing a guide section and elastic members for operation and automatic return.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blocking mechanism is used to retain the second rail at an extended position, then the rail can be securely held in place, but the rail cannot be retracted without complex releasing mechanisms
Solution Approach 1:
The releasing member is driven automatically by the third slide during retraction, eliminating the need for separate manual operation. The system uses its own moving components to trigger the release mechanism, achieving self-service operation.
Solution Approach 2:
The releasing member is pre-positioned to engage with the retention pin before retraction begins. When the third slide moves, it automatically drives the releasing member to disengage the retention pin from the stop, preparing the system for smooth retraction without additional intervention.
2Stability of the object's composition
If the slide rail assembly is designed for fixed extended position, then structural stability is improved, but adaptability to different environments is reduced
Solution Approach 1:
The slide rail assembly transitions from a static fixed-position design to a dynamic adjustable design. The second and third slides can be retracted relative to the first slide by operating the operating member, allowing the assembly to adapt between extended and retracted states based on environmental requirements.
Solution Approach 2:
The effective length of the slide rail assembly can be changed by retracting the second and third slides. This parameter change allows the same assembly to fit different spatial requirements and environmental conditions while maintaining structural integrity through the blocking mechanism.

AI summary
A slide rail assembly (22) includes a first rail (28), a blocking member (34), a second rail (30), and an operating member (36). The first rail (28) defines a longitudinal channel (46). The blocking member (34) is attached to the first rail (28). The second rail (30) is movably connected to the first rail (28) and can be moved to an extended position (P) relative to the first rail (28) in the longitudinal channel (46) to be blocked by the blocking member (34). The operating member (36) is movably connected to the first rail (28) and configured to operate the blocking member (34) so that the second rail (30) is allowed to be retracted relative to the first rail (28) from the extended position (P).
