Auto-Release Slide Retaining Mechanism for Easy Retraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide mechanisms with powerful functions face challenges in allowing easy retraction of a mobile rail into a fixed rail, as they often require manual release or significant impetus, and their assembly and component variability complicate design and production.
Innovation Solution
The proposed auto-release retaining mechanism incorporates a locating member, elastic member, and retaining member on a slide system, utilizing a chute, angular portion, guide grain, and locking member to facilitate temporary positioning and automatic retraction of the second rail into the first rail, with an inclined guide edge and breakaway pull for enhanced functionality and reduced part count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile rail is designed to be retained by a fixed rail when extended to prevent easy sliding back, then the locating function is improved, but the ease of retraction deteriorates
Solution Approach 1:
The locking member is designed to dynamically switch between locked and unlocked states based on the position of the mobile rail. When the mobile rail is extended, the locking member engages with the retaining member to provide stable locating. When the mobile rail is retracted, the locking member automatically disengages, enabling easy retraction without manual intervention.
Solution Approach 2:
The mechanism uses the movement of the mobile rail itself to trigger the locking and unlocking actions. The guide grain and inclined guide edge work together to automatically engage the locking member during extension and disengage it during retraction, making the system self-regulating without requiring external control.
2Ease of operation
If a control member is added to release the locking and push the mobile rail back, then the ease of retraction is improved, but the device complexity increases
Solution Approach 1:
The patent removes the need for a separate control member by integrating the unlocking function directly into the locking member's structure. The locking member itself performs both locking and unlocking functions based on the mobile rail's position, eliminating the need for additional release mechanisms or control components.
Solution Approach 2:
The locking member serves multiple functions: it provides the locking action when engaged, serves as a guide for the mobile rail's movement through its grain, and automatically performs the unlocking function during retraction. This multi-functionality reduces the overall component count while maintaining full operational capability.
3Ease of operation
If an impetus is applied to the mobile rail to automatically release the locking, then the ease of retraction is improved, but the loss of energy increases
Solution Approach 1:
The mechanism prepares for retraction by having the locking member already positioned to disengage as the mobile rail begins to retract. The inclined guide edge is pre-configured to convert the natural retraction movement into the unlocking action, eliminating the need for additional energy input to overcome the locking force.
Solution Approach 2:
The system dynamically adapts to the mobile rail's movement direction. During extension, the locking member engages to prevent backward motion. During retraction, the same locking member automatically transitions to an unlocked state, allowing the mobile rail to move freely back into the fixed rail without requiring external impetus.
4Reliability
If multiple components are used for securing locking, then the reliability is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent combines multiple functions into fewer components. The locking member integrates the locking surface, guide grain, and unlocking mechanism into a single component. The guide section is formed as an integrated feature of the fixed rail structure. This merging reduces the number of parts to manufacture and assemble while maintaining secure locking functionality.
Solution Approach 2:
The locking member is designed as a multi-functional component that provides locking, guiding, and automatic unlocking functions. The guide section serves both as a structural support and as the surface for the guide grain to engage. This multi-functionality reduces component count and simplifies manufacturing and assembly processes.

AI summary
An automatic release retaining mechanism of a slide includes a locating member, an elastic member, and a retaining member operating in conjunction with a first rail and a second rail. The second rail passes through and slides on the first rail. The locating member and the elastic member are disposed on the second rail. The retaining member is disposed on the first rail. The elastic member applies pressure upon the locating member. The locating member holds against the retaining member to temporarily secure the second rail when the second rail slides and extends in relation to the first rail. The second rail is automatically released to be retracted into the first rail when the second rail is pushed into the first rail.
