Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing holding mechanisms fail to maintain stable conduction between a body and a mounting body, especially under vibration conditions, as they lack a mechanism to securely interpose and hold the conduction portion between a holding member and an elastic member in an elastically deformed state.

Innovation Solution

A holding mechanism is designed with a body having a conduction portion, a mounting portion, a holding member that displaces between holding and non-holding positions, and a conductive elastic member that interposes between the conduction portion and the holding member at the holding position, ensuring stable conduction by maintaining the end part of the mounting body in an elastically deformed state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional holding mechanism is used to mount the mounting body on the body, then the mounting body can be attached and detached, but stable conduction cannot be maintained under vibration conditions

Engineering Contradiction:

Improveconduction stabilityVSAvoidvibration impact

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The holding member is designed to be movable between a holding position (where it contacts the end part) and a non-holding position (where it releases the end part). This dynamic capability allows the mechanism to adapt to vibration conditions while maintaining stable conduction when needed, resolving the contradiction between reliability and vibration resistance.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The elastic member acts as an intermediary between the holding member and the end part. It provides continuous contact and pressure to maintain stable conduction while absorbing vibration impacts, thereby improving reliability without being adversely affected by vibration.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the holding portion continuously contacts the end part to maintain stable conduction, then conduction stability improves, but the mounting body cannot be detached

Engineering Contradiction:

Improveconduction stabilityVSAvoidmounting and detachment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The holding member's ability to move between holding and non-holding positions enables both stable conduction during operation and easy detachment when needed. This dynamic design resolves the contradiction between maintaining continuous contact for reliability and allowing detachment for ease of operation.

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If a rigid holding structure is used to prevent deformation under vibration, then structural stability improves, but conduction stability deteriorates due to lack of elastic compensation

Engineering Contradiction:

Improvestructural stabilityVSAvoidconduction stability

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The elastic member changes its physical state (elastic deformation) in response to vibration, allowing it to maintain contact pressure and stable conduction while accommodating structural movements. This parameter change resolves the contradiction between structural stability and conduction stability.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The combination of the rigid holding member structure and the elastic member creates a composite system that benefits from both rigidity (for structural stability) and elasticity (for conduction stability under vibration). This composite approach resolves the contradiction between the two stability requirements.

Inventive Principle:

Principle #40Composite materials

AI summary

A holding mechanism includes a body having a conduction portion, and a mounting portion on which a mounting body having an end part provided with a conduction portion capable of facing the conduction portion is mounted; a holding member that is provided on the body and has a holding portion displaced between a holding position where the holding portion comes into contact with an end part of the mounting body to hold the end part and a non-holding position where the holding portion avoids the end part not to hold the end part; and a conductive elastic member that is installed between at least the conduction portion of the body and the holding portion at least at the holding position. The end part of the mounting body including the conduction portion at the end part is interposed and held between the holding portion at the holding position and the elastic member in an elastically deformed state.
