Vehicle Drive Noise-Absorbing Bracket Structure for Faster Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional service vehicle transmission case requires a closing member to attach a noise-absorbing member, which increases the number of work man-hours and impairs work efficiency.
Innovation Solution
A vehicle driving device noise-absorbing structure that includes a bracket with a tubular portion for the noise-absorbing member, allowing for easier attachment and detachment without the need for a closing member and bolt fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closing member and bolt fixation are used to attach the noise-absorbing member to the annular rib, then the attachment is secure and reliable, but the number of work man-hours increases and work efficiency decreases
Solution Approach 1:
The invention extracts and eliminates the closing member from the attachment system. The noise-absorbing member is directly attached to the annular rib without requiring a separate closing member, thereby reducing the number of parts and assembly steps while maintaining secure attachment through the direct engagement structure
Solution Approach 2:
The invention merges the attachment function into the basic structure itself. The annular rib and noise-absorbing member are designed with integrated engagement features that combine the functions of support, attachment, and noise absorption into a single unified structure, eliminating the need for separate fixing components
2Reliability
If a closing member and bolt fixation are used to attach the noise-absorbing member, then the attachment is secure, but the number of parts and assembly complexity increases
Solution Approach 1:
The closing member is completely removed from the assembly system. The noise-absorbing member attaches directly to the annular rib through integrated engagement features, eliminating the need for separate closing members and reducing overall assembly complexity
Solution Approach 2:
The annular rib structure serves multiple functions simultaneously: it provides structural support, enables noise absorption, and facilitates direct attachment of the noise-absorbing member. This multi-functionality reduces the need for separate specialized components
