Vibration-Isolating Connector Buffer Structure Against Wire Protrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors with spiral-shaped wire buffer members tend to deform over time, leading to protrusion and loss of vibration isolation effectiveness, potentially causing damage or unusual sounds due to contact with vibration sources.
Innovation Solution
A connector design featuring a first buffer member with a spiral-shaped wire, a second buffer member capable of warping in the thickness direction, and a collar member with flanges that sandwich the buffer members to allow radial movement, preventing protrusion and deformation, thus maintaining effective vibration isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a spiral-shaped wire buffer member is used in a connector, then vibration isolation is achieved, but the wire deforms and protrudes after extended use, losing vibration isolation effectiveness
Solution Approach 1:
The buffer member is divided into multiple sections: a first buffer member (spiral-shaped wire), a second buffer member (flat plate-like structure), and a third buffer member (spiral-shaped wire). This segmentation distributes the vibration absorption function across multiple components, preventing any single element from deforming excessively and maintaining overall structural stability during extended use.
Solution Approach 2:
The buffer member uses a composite structure combining different geometric forms (spiral wire and flat plate) and potentially different materials. This composite design allows each section to contribute differently to vibration isolation while相互 constraining each other to prevent deformation and protrusion, thereby maintaining both reliability and shape stability.
2Stability of the object's composition
If the buffer member is constrained rigidly to prevent deformation, then shape stability is improved, but vibration isolation capability is reduced
Solution Approach 1:
The connector design allows dynamic movement of the buffer members within defined constraints. The second buffer member can move radially relative to the collar member, and the flanges allow controlled displacement. This dynamic capability enables the buffer members to absorb vibrations effectively while maintaining overall shape stability and preventing protrusion during extended use.
Solution Approach 2:
The design changes the constraint parameters from rigid fixed positions to controlled movable ranges. The gap between the second buffer member and cylindrical portion, along with the flange constraints, creates optimized parameter ranges that allow sufficient movement for vibration isolation while preventing excessive deformation and protrusion, thus maintaining both stability and reliability.
3Reliability
If the buffer member is allowed to move freely to absorb vibrations, then vibration isolation is improved, but the middle portion protrudes and deformation occurs
Solution Approach 1:
The design incorporates preliminary constraints through the flanges and gap configuration that prevent the buffer member from protruding before deformation can occur. The second buffer member is positioned with a predetermined gap from the cylindrical portion, and the flanges are arranged to limit radial movement, creating preliminary anti-action against potential protrusion while still allowing sufficient movement for vibration absorption.
4Device complexity
If a single buffer member is used, then device complexity is reduced, but vibration isolation performance deteriorates over time due to deformation
Solution Approach 1:
The buffer member is segmented into three distinct sections (first spiral wire, second flat plate, third spiral wire) stacked in sequence. This segmentation distributes the vibration absorption function across multiple components that相互 constrain each other, preventing individual element deformation and maintaining vibration isolation effectiveness over time, while the overall structure remains relatively simple and integrated.

Function Achieved in This Case
The connector effectively reduces deformation and protrusion of the spiral-shaped wire, ensuring consistent vibration isolation and preventing damage or unusual sounds by allowing the second buffer member to move radially and absorb vibrations, maintaining the intended vibration isolation performance over extended use.
