Instrument Panel Elastic Support Joint for Vibration Noise Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional instrument panel support apparatuses generate noise due to repeated contact between the instrument panel and on-board equipment during vehicle travel, primarily caused by vibration, and face challenges in maintaining the panel's position due to deformation.
Innovation Solution
The apparatus employs a connecting portion with a claw portion at the instrument panel and a stepped portion on the on-board equipment, allowing for engagement through elastic deformation to stabilize the panel's position and prevent noise generation by ensuring constant contact and correcting any downward deflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the end portion of the cover panel is disposed close to an upper surface of the instrument panel, then the instrument panel can be supported from the on-board equipment, but the cover panel and the instrument panel are repeatedly contacted by vibration during traveling, generating noise
Solution Approach 1:
A connecting portion is introduced as an intermediary element between the instrument panel and the cover panel. This connecting portion includes an engaging portion on the instrument panel and an engaged portion on the cover panel, which are connected through elastic deformation. The intermediary connecting portion absorbs vibration and prevents direct repeated contact between the instrument panel and cover panel, thereby eliminating noise while maintaining support stability.
Solution Approach 2:
The connecting portion utilizes elastic deformation to change the physical state and flexibility of the connection. By designing the connecting portion with elastic properties, it can dynamically adjust to vibrations and movements, maintaining stable engagement while preventing the rigid contact that causes noise during vehicle traveling.
2Stability of the object's composition
If the instrument panel is rigidly fixed to the on-board equipment, then the panel position is stable, but the panel cannot accommodate deformation and may generate noise
Solution Approach 1:
The connecting portion is designed with dynamic characteristics through elastic deformation, allowing it to adapt to movements and vibrations of the instrument panel. This dynamic connection maintains stable positioning while accommodating deformations, preventing the rigid contact noise that would occur with a completely rigid fixation system.
3Object-generated harmful factors
If the instrument panel is supported with flexible connection, then noise is reduced, but the panel position stability may be compromised
Solution Approach 1:
The connecting portion utilizes elastic deformation to change the physical state and flexibility of the connection. By designing the connecting portion with elastic properties, it can dynamically adjust to vibrations and movements, maintaining stable engagement while preventing the rigid contact that causes noise during vehicle traveling.

AI summary
An instrument panel support apparatus including a support portion configured by an on-board equipment or a fixing member fixed to the on-board equipment, and a connecting portion connecting the support portion and the end of the instrument panel. The connecting portion includes an engaging portion provided at the end of the instrument panel, and an engaged portion provided at the support portion so as to be engaged with the engaging portion when the instrument panel and the support portion are connected by pushing of one of the instrument panel and the support portion to the other of the instrument panel and the support portion in a predetermined direction. The engaging portion is configured to engage with the engaged portion in contact with the engaged portion or a periphery of the engaged portion by an elastic deformation of the engaging portion in the connecting portion.
