Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connectors for vibrating bodies and shielding bodies face issues such as deformation of buffer members leading to protrusions, damage to components, and generation of unusual sounds due to vibration-induced collisions.
Innovation Solution
A connector design featuring a first buffer member with a spiral-shaped wire, a second buffer member capable of warping, and a coupling member with flanges that allow radial movement, preventing protrusions and collisions by absorbing vibrations and maintaining stability.

Engineering Contradiction Analysis
1Reliability
If a spiral-shaped wire buffer member is used in a connector, then vibration isolation is achieved, but the middle portion protrudes in the axial direction after extended use
Solution Approach 1:
The buffer member is divided into multiple independent spiral-shaped wires instead of a single continuous structure. Each wire acts as an independent vibration isolation element, preventing the protrusion problem that occurs in single-wire designs after extended use.
Solution Approach 2:
Multiple spiral-shaped wires are arranged concentrically with different outer diameters, with smaller diameter wires nested inside larger diameter wires. This nested configuration allows the wires to support each other and maintain structural stability while providing effective vibration isolation.
2Stability of the object's composition
If the coupling member is fixed rigidly to the vibrating body, then connection stability is achieved, but repeated collision occurs when shielding body is vibrated
Solution Approach 1:
The coupling member is designed with dynamic characteristics that allow it to move slightly relative to the vibrating body when the shielding body is vibrated. This dynamic response prevents rigid collision while maintaining stable connection during normal operation, reducing wear and damage from repeated impacts.

Function Achieved in This Case
The connector effectively isolates vibrations, reduces the likelihood of collisions, and prevents unusual sounds by ensuring the buffer members deform minimally and maintain their position, thus protecting components and enhancing operational stability.

AI summary
A connector includes a first buffer member that includes a spiral-shaped wire in a plan view, a second buffer member that has a substantially annular and flat plate-like shape, and that is capable of warping in a thickness direction, a collar member that includes a first flange facing a radially inner side of the first buffer member, and a second flange facing a radially inner side of the second buffer member, and a coupling member. A gap for allowing the second buffer member to move in a radial direction is formed between the second buffer member and a cylindrical portion. A distance between a position of a surface of the second flange, the surface being on a side of the second buffer member, and a position of a lowest end of the collar member is greater than a distance between a position of a surface of the first flange, the surface being on a side of the first buffer member, and the position of the surface of the second flange, the surface being on the side of the second buffer member, in a view in an axial direction. According to the present invention, it is possible to provide a connector in which a buffer member including a spiral-shaped wire deforms less in the course of use, in which no middle portion protrudes to the outside, and in which a coupling member is less likely to collide with a vibrating body even if a shielding body is vibrated.
