Multi-Buffer Connector Structure for Longer Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors for vibrating bodies and shielding bodies suffer from short vibration-proofing lifetime due to permanent deformation of spiral-shaped wire buffer members caused by fatigue, leading to deteriorated vibration-proofing performance.
Innovation Solution
A connector design incorporating a first buffer member with a spiral-shaped wire, a second buffer member with a substantially annular and flat plate-like shape capable of warping, and a collar member with flanges to absorb vibrations, allowing the second buffer member to move radially and distribute force, thereby extending the vibration-proofing lifetime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spiral-shaped wire buffer member is used in a connector, then vibration isolation performance is improved, but permanent deformation occurs due to spring fatigue leading to short vibration-proofing lifetime
Solution Approach 1:
The single spiral-shaped wire buffer member is divided into multiple buffer members (first buffer member with spiral-shaped wire, second buffer member with plate-like shape, and optionally third buffer member). This segmentation distributes the vibration absorption load across multiple components, preventing any single member from undergoing excessive deformation that would lead to permanent set and failure.
Solution Approach 2:
The invention uses composite buffer member structures combining different geometries and materials - the spiral-shaped wire buffer member (first buffer member) works in conjunction with the plate-like second buffer member. This composite approach allows each member to contribute different vibration damping characteristics while sharing the mechanical load, thereby extending overall system lifetime.
2Reliability
If multiple buffer members are used to distribute vibration forces, then vibration-proofing lifetime is extended, but device complexity increases
Solution Approach 1:
Multiple buffer members are integrated into a single connector assembly where the first buffer member, second buffer member, and third buffer member are positioned between the collar member and coupling member. This merging approach allows the multiple buffer members to function as a unified vibration isolation system while maintaining a compact structure, thereby extending lifetime without proportionally increasing overall device complexity.
Solution Approach 2:
The buffer members are arranged in a nested configuration where the first buffer member, second buffer member, and third buffer member are positioned concentrically or in layered fashion within the connector. This nesting allows multiple vibration-absorbing components to occupy minimal space while working together to distribute vibration forces, extending vibration-proofing lifetime without significantly increasing device complexity.

Function Achieved in This Case
