Slide Assembly Fixing Structure for Strong Rack Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixing devices for slide assemblies compromise structural strength and stability due to the presence of slots in installation members, which affect secure connection to racks.
Innovation Solution
A fixing device comprising a support member with a bracket, an insertion member, an engaging member, and a resilient member, where the engaging member's arm extends through the insertion member's slot with a protrusion, secured by a resilient force, and installation members connect to the rack, enhancing stability and secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the arm directly extends through the installation member with the hook protruding from the slot, then the fixing device can be assembled, but the hook affects the installation of the installation member to the rack and reduces structural strength
Solution Approach 1:
The invention divides the fixing device into separate functional components: the installation member (without slots) and the engaging member (with arm and hook). The arm is contained within the engaging member rather than extending through the installation member, separating the installation function from the engagement function. This allows the installation member to maintain full structural strength while the engaging member performs the locking action.
Solution Approach 2:
The arm and hook mechanism is extracted from the installation member and placed in a separate engaging member. This extraction removes the harmful element (the protruding arm affecting installation) from the installation member, allowing the installation member to be a solid, slot-free component that maintains structural integrity while still enabling the fixing function through the separate engaging member.
2Adaptability or versatility
If the slot is present in the installation member to allow arm passage, then the engaging member can function, but the slot reduces structural strength and affects stability
Solution Approach 1:
The invention segments the functional requirements by placing the slot only in the engaging member, not in the installation member. The installation member remains a solid, stable component, while the engaging member contains the slot necessary for arm movement and engagement. This segmentation allows each component to optimize its structure for its specific function.
Solution Approach 2:
The engaging member acts as an intermediary between the installation member and the rack. It contains the slot and arm mechanism needed for engagement, while the installation member remains a simple, stable component that connects to the rack. The intermediary engaging member absorbs the complexity and structural compromise, protecting the installation member's stability.
3Reliability
If the hook protrudes from the slot by spring force, then the fixing device can engage the rack, but the protruding hook interferes with installation to the rack
Solution Approach 1:
The invention uses preliminary action by designing the arm to be retractable into the engaging member before installation. The spring force holds the arm in a retracted position during installation, allowing the installation member to be freely inserted into the rack without interference. After installation, the arm can extend to perform the engagement function, separating the installation phase from the engagement phase.
Solution Approach 2:
The arm is designed as a dynamic component that can change its position between retracted and extended states. During installation, the arm is dynamically held in the retracted position to avoid interference. After installation, it can dynamically extend to engage the rack. This dynamic behavior resolves the contradiction between needing the arm to protrude for engagement and needing it to be retracted for easy installation.

Function Achieved in This Case
The solution provides a secure and stable connection of the slide assembly to the rack, maintaining structural integrity while allowing easy disassembly, thereby addressing the limitations of conventional fixing devices.
Implementation Method 1
A resilient member provides a force to the engaging member to extend the first protrusion beyond the slot of the insertion member

AI summary
A fixing device of a slide assembly has a bracket. The fixing device includes an insertion member, an engaging member and a resilient member. The insertion member is connected to the bracket and has a slot. The engaging member is pivotally connected relative to the bracket and has an operation portion and an arm which extends through the slot of the insertion member. The arm has a first protrusion. The resilient member provides a force to the engaging member to extend the first protrusion beyond the slot of the insertion member. By moving the operation portion, the first protrusion is controlled to be retracted toward the slot of the insertion member.
