Slide Rail Mounting Structure for Tool-Free Retention Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mounting mechanisms for slide rail assemblies lack a supportive structure to prevent deflection during installation and long-term usage, leading to misalignment and ineffective retention of retaining members.
Innovation Solution
A mounting device comprising a base portion, a blocking portion, and an operating portion, where the blocking portion is adjacent to a mounting hole and can be moved away by the operating portion to allow disengagement of a positioning member, enabling rapid mounting and removal of a carried object without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the retaining member is only attached to the slide rail by the fastener, then the installation process is simple, but the retaining member may be deflected during installation or under long term usage
Solution Approach 1:
The mounting device is divided into three functional segments: base portion (providing support), blocking portion (providing retention), and operating portion (enabling control). This segmentation allows each part to perform its specific function effectively, with the base portion preventing deflection and the blocking portion ensuring reliable retention.
Solution Approach 2:
The blocking portion acts as an intermediary between the retaining member and the mounting hole, providing additional support and preventing direct stress on the fastener-only connection. This intermediary structure enhances reliability without complicating the overall installation process.
2Device complexity
If the retaining member is only attached by fastener without additional support structure, then the device complexity is reduced, but the through slot may not align with the positioning portion
Solution Approach 1:
The base portion is pre-configured with a specific geometry that guides the retaining member into proper alignment as it is inserted. This preliminary alignment action ensures that the through slot and positioning portion are correctly positioned before the blocking portion engages, eliminating alignment issues without requiring complex adjustment mechanisms.
Solution Approach 2:
The mounting device structure itself provides the alignment function through its geometric design. The base portion and blocking portion are shaped to automatically guide and position the retaining member correctly during insertion, making the system self-aligning without requiring external alignment tools or complex adjustment procedures.
3Device complexity
If a traditional fastener-only mounting mechanism is used, then the device structure is simple, but rapid mounting and dismounting without tools is not achieved
Solution Approach 1:
The blocking portion is designed to be movable rather than fixed, allowing it to be displaced by the operating portion during dismounting. This dynamic design enables rapid tool-free removal of the retaining member by simply moving the blocking portion, while maintaining a simple overall structure that does not require complex mechanisms.
Solution Approach 2:
The blocking portion is extracted from the traditional fixed fastener structure and made into a separate, movable component controlled by the operating portion. This extraction allows the retention and release functions to be independently controlled, enabling rapid tool-free operation while keeping the base fastening structure simple and reliable.

AI summary
A mounting device (20) is configured to mount a carried object (24) to a connecting board (36). The connecting board (36) is arranged with a mounting hole (40) for mounting a positioning member (42) of the carried object (24). The mounting device (20) includes a blocking portion (60) adjacent to the mounting hole (40), an operating portion (62) operatively connected to the blocking portion (60), and a base portion (58) connected to the connecting board (36) and the blocking portion (60). Wherein, when the positioning member (42) of the carried object (24) enters the mounting hole (40) of the connecting board (36), the blocking portion (60) is configured to block the positioning member (42) ; and when the operating portion (62) is operated to move the blocking portion (60) away from the mounting hole (40), the positioning member (42) is able to disengage from the mounting hole (40).
