Vibration Damping Bracket Latch Mechanism for Secure Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vibration damping devices with lateral-insertion type structures face challenges in reliably preventing the second attachment member from dislodging from the bracket, as the hook part's deformation under force leads to insufficient resistance, risking unlocking.
Innovation Solution
The vibration damping device incorporates a bracket with latches that have a slope portion and outer recesses in the second attachment member, where the latch's distal end face is latched by the forward wall inner face of the recess, providing a compression force that restricts dislodgement and enhances resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hook part is used to lock the second attachment member to the bracket, then the attachment reliability is improved, but the hook part deforms under force leading to insufficient resistance and potential unlocking
Solution Approach 1:
The attachment mechanism is divided into multiple functional elements: the latch body, the arm portion with elastic deformation capability, and the engagement surface. This segmentation allows each part to perform its specific function optimally - the arm deforms elastically to absorb force while the engagement surface provides the locking action, preventing the single-point failure mode of the hook design
Solution Approach 2:
The latch incorporates an elastic arm portion that can dynamically deform under applied forces and return to its original position. This dynamic capability allows the latch to absorb dislodgement forces through elastic deformation rather than rigid resistance, preventing the deformation and failure that occurs in static hook designs
2Ease of operation
If the second attachment member is attached from the lateral side to the bracket, then the ease of operation is improved, but the risk of dislodgement increases
Solution Approach 1:
The latch is pre-positioned in the bracket at the location where it will effectively engage the second attachment member. This preliminary positioning ensures that when the lateral attachment is performed, the latch is already in place to prevent dislodgement, combining ease of lateral installation with reliable anti-dislodgement protection
Solution Approach 2:
The latch acts as an intermediary element between the bracket and the second attachment member. It provides the locking function without interfering with the lateral insertion process, mediating between the ease of lateral attachment and the need for secure anti-dislodgement protection
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
This configuration effectively prevents dislodgement by exerting increased resistance through the latch's compression force, ensuring the second attachment member remains securely attached to the bracket.
Implementation Method 1
a first attachment member and a second attachment member connected by a main rubber elastic body
Implementation Method 2
the bracket includes latches having flexibility and respectively extending from opposed inner faces of the respective opposed walls forward in a direction of attachment of the vibration-damping device main unit to the bracket
Implementation Method 3
each of the latches has a slope portion sloping inward in the width direction of the bracket toward a distal end of the latch such that a distal end face of the latch is inserted in the corresponding outer recess
Implementation Method 4
the distal end face of the latch is latched by a forward wall inner face of the corresponding outer recess, and displacement of the second attachment member relative to the bracket in a direction of dislodgment opposite to the direction of attachment is limited

AI summary
A vibration damping device including a vibration-damping device main unit attached to a bracket from a lateral side by a second attachment member being fitted to opposed walls provided on widthwise opposite sides of the bracket. The bracket includes flexible latches extending from the respective opposed walls forward in a direction of attachment. The second attachment member includes outer recesses respectively opening onto surfaces overlapped with the respective opposed walls. Each latch has a slope portion sloping inward in a width direction of the bracket such that a distal end face of the latch is inserted in the corresponding outer recess. The distal end face of the latch is latched by a forward wall inner face of the outer recess, and displacement of the second attachment member relative to the bracket in a direction of dislodgment opposite to the direction of attachment is limited.
