Slide Rail Locking Mechanism for Secure Chassis Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail devices for mounting computer chassis lack secure fastening mechanisms, allowing components to be easily detached, posing safety concerns.
Innovation Solution
A slide rail device with a movable locking member that transitions between blocking and non-blocking positions, utilizing an engagement member with elastic force to secure the mounting path, and a disengagement feature for safe and secure mounting of carried objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the slot is designed as an open path for easy mounting, then the ease of operation is improved, but the safety and security of the mounted object deteriorates
Solution Approach 1:
The locking member is designed to be movable between a first position (blocking the mounting path) and a second position (away from the mounting path). This dynamic mechanism allows the system to transition between locked and unlocked states, enabling easy mounting when unlocked while providing security when locked. The movable nature of the locking member resolves the contradiction by making the security feature adjustable rather than fixed.
Solution Approach 2:
The engagement member utilizes elastic force to automatically engage with the mounting member when the slide rail is retracted, and automatically disengage when the slide rail is extended. This self-service mechanism eliminates the need for manual operation of the locking mechanism, providing both ease of operation (automatic engagement) and reliability (secure locking) simultaneously.
2Reliability
If the locking member blocks the mounting path to ensure safety, then the reliability is improved, but the ease of operation deteriorates due to additional locking steps
Solution Approach 1:
The engagement member with elastic force automatically performs the locking action by engaging with the mounting member when the slide rail is retracted, and automatically unlocks when the slide rail is extended. This eliminates the need for separate manual locking steps, maintaining high reliability while preserving ease of operation.
Solution Approach 2:
The locking member is positioned to block the mounting path before the mounting process begins. This preliminary blocking action ensures that the object cannot be accidentally detached during operation, providing reliability without adding complexity to the actual mounting steps.
3Ease of operation
If the engagement member uses elastic force for automatic engagement, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The engagement member combines multiple functions into a single component: it provides the elastic force for automatic engagement, acts as the locking mechanism, and guides the mounting member into place. By merging these functions into one integrated component rather than separate parts, the system achieves automatic engagement while minimizing the increase in device complexity.
Solution Approach 2:
The engagement member serves multiple purposes: it provides the elastic restoring force, engages with the mounting member to secure the load, and works with the locking member to control access to the mounting path. This multi-functionality reduces the need for additional specialized components, balancing ease of operation with acceptable device complexity.
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 solution provides a secure and safe mounting mechanism that prevents accidental detachment of carried objects, ensuring stability and safety by automatically locking the mounting path when the slide rail is retracted.
Implementation Method 1
The engagement member has an elastic part and an engagement part. The engagement part is configured to be engaged with the through hole in response to an elastic force of the elastic part.

AI summary
A slide rail device is configured to mount a carried object. The carried object includes a plurality of mounting members. The slide rail device includes an auxiliary component, a slide rail, an operating member and a locking member. The slide rail is movable relative to the auxiliary component. The slide rail has a mounting path for allowing the mounting members of the carried object to pass through. The locking member is movable relative to the operating member between a first position and a second position. Wherein when the locking member is located at the first position, the locking member blocks the mounting path; wherein when the locking member is located at the second position, the locking member is away from the mounting path.
