Slide rail bracket assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slide rail bracket mounting systems are inconvenient to lock or unlock, requiring significant effort and posing a risk of pinch accidents during operation.
Innovation Solution
A slide rail bracket assembly with a fastening device featuring a hook member and a release member that uses leverage to move the hook member, allowing easy locking and unlocking with reduced effort, and includes a notch for engagement with the mounting plate to prevent vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user operates the connecting device directly by biasing the lever hook, then the slide rail bracket can be locked or unlocked, but it requires significant effort and is inconvenient to operate
Solution Approach 1:
A release member is introduced as an intermediary between the user's hand and the hook member. The release member includes a pull-off portion that the user operates, which through a lever arm connected to the spring arm, translates small user input forces into larger forces that bias the hook member away from the bracket body, enabling easy unlocking without directly manipulating the lever hook
Solution Approach 2:
The system uses a spring arm that can dynamically change its state between biased and unbiased positions. When the release member is operated, the spring arm is biased away from the bracket body, causing the hook member to disengage. When the release member returns to its original position, the spring arm's elasticity causes it to return, allowing the hook member to engage with the bracket body, providing automatic locking/unlocking action
2Ease of operation
If the lever hook is directly biased for locking or unlocking, then the operation can be completed, but pinch accidents can occur during mounting or dismounting
Solution Approach 1:
The release member serves as a safety intermediary that keeps the user's fingers away from the pinch points between the lever hook and the frame structure. The user operates the pull-off portion of the release member, which is positioned far from the engagement area, while the mechanism internally actuates the hook member, eliminating the need for users to place fingers in dangerous zones
Solution Approach 2:
The dangerous function of directly biasing the lever hook is extracted from the user's direct operation. The release member and spring arm mechanism take over the force application function, separating the user's manual operation from the high-force engagement zone where pinch accidents would occur
3Device complexity
If a simple hook mechanism is used, then the structure is simple, but the locking is not secure and allows vibration
Solution Approach 1:
The fastening device merges multiple functions into a single integrated mechanism: the hook member provides the primary locking engagement, the spring arm provides continuous spring force to maintain engagement pressure, and the release member provides controlled actuation. This combination creates a secure locking system that prevents vibration while remaining relatively simple in overall structure
Solution Approach 2:
The spring arm introduces dynamic elasticity to the locking mechanism. Instead of a rigid fixed-position hook, the spring arm can dynamically adjust its position and apply continuous restoring force, ensuring the hook member remains firmly engaged with the bracket body and can absorb vibrational forces without disengaging

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effortless locking and unlocking of the slide rail bracket to the mounting plate, reducing the risk of pinch accidents and ensuring secure attachment while preventing vibration.
Implementation Method 1
two spring arms respectively extended from the hook bases
Implementation Method 2
a release member operable to move the hook member by leverage so that the fastening device can be locked to or unlocked from the mounting plate conveniently with less effort

AI summary
A slide rail bracket assembly includes a slide rail bracket including a bracket body and a positioning member affixed to one side of the bracket body, and a fastening device including a hook member that includes two hook bases affixed to an opposite side of the bracket body, two spring arms respectively extended from the hook bases, and a hooking portion connected between the spring arm, and a release member that includes two actuation portions respectively pivotally connected to the spring arms of the hook member, two bearing portions respectively extended from respective one ends of the actuation portions and two pull-off portions respectively extended from respective opposite ends of the actuation portions. Operating the release member to bias the actuation portions relative to the hook member can force the bearing portions into abutment against the bracket body and move the spring arms in direction away from the bracket body.
