Transfer Device Noise-Absorbing Structure With Cover-Assisted Bracket Mounting
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 due to the need for bolting the closing member to an annular rib.
Innovation Solution
A vehicle driving device noise-absorbing structure featuring a noise-absorbing member with a first tubular portion and engaging portion, where a cover member with a second tubular portion covers the outer peripheral portion, allowing the engaging portion to be pushed against the bracket, reducing the need for bolts and simplifying attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closing member is used to attach the noise-absorbing member to the annular rib, then the noise-absorbing member can be securely attached, but the number of work man-hours increases and work efficiency decreases
Solution Approach 1:
The invention extracts the closing member from the attachment system, eliminating the need for separate closing components. The noise-absorbing member itself is designed with an integrated closing structure that forms the annular rib, combining what were previously separate elements into one unified component. This reduces the number of parts and assembly steps while maintaining secure attachment.
Solution Approach 2:
The invention merges the noise-absorbing member and the closing member into a single integrated component. The noise-absorbing member is formed with an annular rib that protrudes from its rear surface, and this rib is directly attached to the bracket, eliminating the need for a separate closing member. This consolidation reduces assembly complexity and work man-hours.
2Strength
If a closing member is bolted to the annular rib, then secure attachment is achieved, but the attachment process becomes more complex and time-consuming
Solution Approach 1:
The invention removes the closing member and bolts from the attachment system. Instead of bolting a closing member to the annular rib, the noise-absorbing member's integrated annular rib is directly mounted to the bracket using simple mounting portions, eliminating complex bolting operations while maintaining secure attachment.
Solution Approach 2:
Instead of using a closing member to secure the noise-absorbing member, the invention inverts the approach by making the noise-absorbing member itself the securing element. The annular rib of the noise-absorbing member protrudes and engages with the bracket, with mounting portions that provide secure attachment without requiring additional closing components.
3Reliability
If multiple components (closing member, annular rib, noise-absorbing member) are used, then secure attachment is achieved, but the number of parts increases and assembly time increases
Solution Approach 1:
The invention combines the noise-absorbing member and closing member into one integrated component. The noise-absorbing member is formed with an annular rib that serves as the closing structure, eliminating the need for separate closing members. This reduces the total number of parts and simplifies the assembly process, reducing assembly time while maintaining secure attachment.
Solution Approach 2:
The integrated noise-absorbing member performs multiple functions: it absorbs noise, forms the closing structure with its annular rib, and provides mounting portions for direct attachment to the bracket. This multi-functionality eliminates the need for separate closing members and reduces the overall component count, streamlining the assembly process.
