Sonic Wave Apparatus Elastomer Cushioning Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sonic-wave apparatuses mounted on vehicles experience disturbances such as vibrations and physical impacts, leading to alterations in the attached state of elastic members, potentially causing detachment during vehicle movement, washing, or maintenance.
Innovation Solution
A sonic wave apparatus with a columnar apparatus body, a cushioning member formed from elastomer, and a protrusion portion that elastically contacts the vehicle part, maintaining the mounted state by providing a step between the sonic wave unit and the support section, and using a tubular portion and flange configuration to suppress vibrations and impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an elastic member is used to cover the assembly section of the ultrasonic sensor module during mounting, then the mounting process is simplified and the elastic member can accommodate the assembly section, but the elastic member may detach or alter its attached state due to vibrations and physical impacts during vehicle operation
Solution Approach 1:
The cushioning member is divided into functionally distinct portions: a tubular portion that covers the front-end section, a flange that extends from the tubular portion, and a protrusion portion that protrudes from the flange. This segmentation allows each portion to perform its specific function - the tubular portion provides cushioning, the flange provides structural support, and the protrusion portion prevents detachment by engaging with the vehicle part or surrounding structures.
Solution Approach 2:
The protrusion portion extends in the extending direction of the cushioning member, adding a dimensional element that protrudes outward to engage with the vehicle part or surrounding structures. This dimensional extension transforms the cushioning member from a simple covering element into an actively engaged mounting component that resists detachment forces.
2Reliability
If the cushioning member is formed as one body from elastomer with a tubular portion, flange, and protrusion portion, then the mounted state is reliably maintained by suppressing detachment, but the structural complexity of the cushioning member increases
Solution Approach 1:
Multiple functional elements (tubular portion, flange, and protrusion portion) are merged into a single cushioning member formed as one body from elastomer. This integration ensures coordinated deformation and movement of all portions during mounting and operation, while the unified elastomeric structure maintains flexibility and shock-absorbing properties across the entire component.
Solution Approach 2:
The cushioning member utilizes the elastomeric material property to change its physical state under different conditions - deforming under compression from vibrations and impacts, then recovering its original shape. This parameter change (deformation and recovery) allows the single-body structure to absorb disturbances while maintaining the reliable mounted state.
3Reliability
If the protrusion portion protrudes towards the vehicle part to prevent detachment, then the mounted state is maintained under vibrations and impacts, but the protrusion portion may interfere with the insertion process through the attachment through-hole
Solution Approach 1:
The protrusion portion is designed to engage with the vehicle part or surrounding structures after the insertion process is complete. During insertion, the flexible elastomeric material allows the protrusion portion to deform and accommodate the passage through the attachment through-hole. Once mounted, the protrusion portion returns to its engaged position to prevent detachment, thus performing the protective function only when needed.
Solution Approach 2:
The protrusion portion transitions from a passive state during insertion to an active engaged state during operation. The elastomeric material enables dynamic deformation during the insertion process to avoid interference, then maintains a stable engaged configuration during vehicle operation to prevent detachment from vibrations and impacts.

Function Achieved in This Case
The solution effectively maintains the mounted state of the sonic wave apparatus on the vehicle, preventing detachment and enhancing mounting performance while withstanding disturbances like vibrations and physical impacts during vehicle use and maintenance.
Implementation Method 1
The cushioning member is formed as one body from elastomer
Implementation Method 2
The protrusion portion is in contact elastically with a part (for example, a bezel) that intervenes between the part of the vehicle and apparatus body or with the part of the vehicle... suppress vibrations and impacts

AI summary
A sonic wave apparatus is provided with an apparatus body and a cushioning member. The apparatus body is configured with a columnar front-end section having a level difference. The apparatus body includes a sonic wave unit disposed on the front-end section and a support member supporting the sonic wave unit. The apparatus body is inserted into and attachment hole that is formed on a part of the vehicle. The cushioning member includes a tubular portion covering the front-end section, a plate shaped flange that is extended from one end of the support section of the tubular portion, along an end surface of side being a front-end side of the support section, and a protrusion portion that is arranged on the flange and protrudes in an extending direction from the flange of the tubular portion. The cushioning member is formed as one body from elastomer.
