Solution Overview

Problem

Conventional slide rail mounting systems are inconvenient and time-consuming due to the use of screws, making installation and uninstallation laborious.

Innovation Solution

A mounting apparatus featuring a mounting bracket with inserting pins and a spring-loaded clipping member that engages with rack posts of varying hole sizes, allowing for easy attachment and detachment of the slide rail by sliding and deforming to secure or release the pins from the holes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screws are used for mounting the slide rail to the bracket, then the mounting is secure and reliable, but the installation and uninstallation process becomes inconvenient and time-consuming

Engineering Contradiction:
Improvemounting securityVSAvoidinstallation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent employs a spring-loaded clipping member that can dynamically change its clamping force. The spring mechanism allows the clip to automatically adjust to the mounting bracket, providing secure holding during normal operation while enabling quick release when force is applied to the release button. This dynamic characteristic resolves the contradiction by maintaining reliability during use while allowing rapid installation and uninstallation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spring-loaded clip automatically engages with the mounting bracket when the slide rail is inserted, securing itself without requiring separate fastening actions. The release mechanism allows the clip to self-disengage with a simple button press. This self-service characteristic eliminates the need for tools and multiple steps, reducing installation time while maintaining secure mounting during operation.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If a spring-loaded clipping member is used for quick mounting, then installation and uninstallation become convenient and fast, but the risk of accidental disengagement increases

Engineering Contradiction:
Improveinstallation convenienceVSAvoidanti-disengagement reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The clipping member features asymmetric design where the engagement direction requires significant force to disengage, while the release direction is facilitated by the spring mechanism and release button. The clip engages automatically in one direction but requires deliberate action (pressing the release button) to disengage in the opposite direction. This asymmetric design ensures convenient installation while preventing accidental disengagement, as normal operational forces cannot overcome the engaged state.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The spring mechanism is pre-loaded to maintain constant engagement pressure on the mounting bracket, creating a preliminary counter-force that prevents accidental disengagement. The spring's elastic energy stores the necessary force to resist external disturbances, while the release button provides a controlled method to overcome this pre-loaded spring force when intentional release is required. This preliminary anti-action ensures reliability without compromising ease of operation.

Inventive Principle:
Principle #9Preliminary anti-action

AI summary

A mounting apparatus is provided for mounting a slide rail to a rack post defining a number of through holes. The mounting apparatus includes a mounting bracket and a clipping member. The mounting bracket includes a sliding portion slidably engaged with the slide rail and an end plate perpendicularly extending from a front end of the sliding portion. Two inserting pins extend from the end plate through corresponding through holes of the rack post. The clipping member includes a first end fixed to the mounting bracket, and a second end approaching the end plate. A tab protrudes from the clipping member and is adjacent to the second end of the clipping member. The second end or the tab of the clipping member abuts against a side of rack post opposite to the end plate to avoid the inserting pins to disengage from the corresponding through holes.
