Floating Fastener Pad Structure for Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional floating fasteners fail to effectively absorb shaking and vibration, leading to poor signal quality in electronic components due to external forces, causing displacement and yaw.
Innovation Solution
A floating fastener design featuring a base with a through hole, a positioning member with a joint portion that moves in and out, an elastic member, and a soft material pad that absorbs vibrations, combined with a cushion and metal gasket for enhanced shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the positioning plate and fixing plate are rigidly connected, then the structural strength is improved, but the shaking and vibration under external force increases, causing poor signal quality
Solution Approach 1:
The patent introduces a pad made of soft material (such as rubber or plastic) between the positioning plate and fixing plate. This pad is designed to deform under external force, providing cushioning before the vibration can affect the electronic components. The pad absorbs and dampens the shaking and vibration, preventing them from being transmitted to the rigid connection between the positioning plate and fixing plate, thus resolving the contradiction between structural strength and vibration reduction.
2Stability of the object's composition
If the connecting seat is fixed rigidly to the positioning plate, then the stability is improved, but the displacement and yaw under external force increase, affecting electronic components
Solution Approach 1:
The patent changes the physical parameter of the connection interface by introducing a soft material pad. This pad allows for controlled deformation and movement, transforming the rigid connection into a semi-rigid connection that can accommodate displacement and yaw. The pad's material properties (softness, elasticity) are specifically selected to maintain stability while absorbing external forces, preventing excessive displacement and yaw that would otherwise affect the electronic components.
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
The design effectively reduces shaking and vibration, preventing poor signal quality by providing double-layer shock absorption and clamping functions, thereby mitigating the impact of external forces on electronic components.
Implementation Method 1
the docking portion is externally provided with a soft material pad against one side of the seat body of the base to achieve the purpose of using the pad to absorb the shaking and vibration force after assembly
Implementation Method 2
the elastic member B is attached to the screw A1, and the cap A and the elastic member B are fixed on the connecting seat C

AI summary
Floating fastener includes base including main body provided with through hole, resisting ring protruded inside through hole, seat body extended around main body and docking portion protruded from seat body, positioning member having shank inserted into through hole, head located at one end of shank outside main body, joint portion located at an opposite end of shank to move in and out of docking portion and stopper provided between joint portion and shank to abut against resisting ring, elastic member set on shank and stopped between head and resisting ring, and pad provided with inner hole which is inserted outside docking portion of base, so that pad abuts against seat body near the docking portion. The pad is made of soft material, which can achieve the purpose of absorbing the shaking and vibration of the floating fastener under the influence of external force.
