Panel Protrusion Silencer With Integrated Fitting and Stopper Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing silencers for vehicles require additional mounting members like staples or fixing members made of different materials, increasing component count and material costs, and posing recycling challenges.
Innovation Solution
A silencer design with a protrusion cover portion that includes a fitting portion and a stopper portion, allowing it to be mounted on a panel with a protrusion without separate mounting members, using a single material for the silencer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If staples or fixing members are used to mount the silencer on the protrusion, then the silencer can be securely mounted, but the number of components and material cost increase
Solution Approach 1:
The mounting function is merged into the silencer body itself. The silencer includes an integrated mounting structure with a mounting surface that directly engages with the protrusion, eliminating the need for separate staples or fixing members. This integration maintains secure mounting while reducing component count.
Solution Approach 2:
The silencer is designed to mount itself onto the protrusion without requiring additional mounting members. The mounting structure is built into the silencer body, allowing it to self-fasten to the panel protrusion through its own structural features.
2Reliability
If staples or fixing members made of different material are used, then the silencer can be mounted on the protrusion, but material cost increases and recycling becomes difficult
Solution Approach 1:
The silencer is constructed from a single homogeneous material throughout its body, including the integrated mounting structure. This eliminates the need for different materials like metal staples mixed with plastic or foam body, allowing the entire silencer to be recycled together as one material type.
3Reliability
If additional mounting members are used, then the silencer can be mounted on the protrusion, but material cost increases
Solution Approach 1:
The mounting function is merged into the silencer body itself. The silencer includes an integrated mounting structure with a mounting surface that directly engages with the protrusion, eliminating the need for separate staples or fixing members. This integration maintains secure mounting while reducing component count.
4Shape
If the silencer is folded to create a bag-shaped protruding portion, then it can cover the protrusion, but additional mounting members are still needed
Solution Approach 1:
The mounting function is merged into the silencer body itself. The silencer includes an integrated mounting structure with a mounting surface that directly engages with the protrusion, eliminating the need for separate staples or fixing members. This integration maintains secure mounting while reducing component count.

AI summary
A silencer includes a panel cover portion and a protrusion cover portion that extends upward from the panel cover portion and covers a protrusion of a panel. The protrusion cover portion includes a first protrusion cover portion and a second protrusion cover portion that have an elongated shape and cover the protrusion. The first protrusion cover portion includes a first protrusion cover body portion and a fitting portion that extends from an end of the first protrusion cover body portion with respect to a longitudinal direction. The second protrusion cover portion includes a second protrusion cover body portion and a stopper portion that extends from an end of the second protrusion cover body portion with respect to the longitudinal direction. The protrusion cover portion has a bag shape that covers the protrusion with the fitting portion and the stopper portion being fitted to each other.
