Vehicle Storage Buffer Material Wobbling Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage devices for vehicles face issues with wobbling and dimensional errors, leading to abnormal sounds and increased costs due to complex fitting structures and the need for accurate part formation, especially when using buffer materials like non-woven fabrics.
Innovation Solution
A storage device design incorporating a buffer material, such as rubber or non-woven fabric, positioned between members to absorb wobbling and prevent movement, allowing for easier tuning and reduced costs by eliminating the need for precise part alignment and complex fitting structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional fitting structure with slope portions and engagement pieces is used, then temporal fixing and positioning can be achieved, but dimensional errors cause abnormal sounds and wobbling cannot be reliably prevented
Solution Approach 1:
A buffer member is introduced as an intermediary element between the engagement piece and the concave portion. This buffer member absorbs dimensional errors and fitting deviations, preventing abnormal sounds while maintaining the temporal fixing and positioning function of the original engagement structure.
Solution Approach 2:
The buffer member is positioned in advance between the engagement piece and the concave portion to cushion and absorb potential dimensional errors and fitting deviations before they can cause abnormal sounds or wobbling, thereby preemptively resolving the manufacturing precision issue.
2Stability of the object's composition
If buffer material such as non-woven fabric is bonded to multiple members to prevent wobbling, then wobbling can be suppressed, but the number of operations increases and cost increases
Solution Approach 1:
The buffer function is merged into a single buffer member that is integrated into the fitting structure between the lid inner and lid outer. This consolidation eliminates the need to bond buffer materials to multiple separate members, reducing the number of operations while maintaining effective wobbling suppression.
Solution Approach 2:
The buffer member serves multiple functions simultaneously: it acts as a cushioning element to suppress wobbling, compensates for dimensional errors, and maintains the fitting between engagement pieces and concave portions. This multi-functionality eliminates the need for separate buffer materials on multiple members.

Function Achieved in This Case
The buffer material effectively suppresses wobbling, simplifies the tuning process, and reduces production costs while maintaining engagement strength and reliability, making it suitable for applications like eyeglasses holders and cup holders.
Implementation Method 1
a buffer material disposed on an inside of the case member (1), which can abut against the article to be housed, and includes a buffer portion formed to extend at one portion

AI summary
A storage device for vehicle includes one member which can house an article on an inside; and another member attached to an outside of the one member in a state wherein at least one portion is superimposed. An essential portion includes a buffer material disposed inside the one member and can abut against the article to be housed therein, and the buffer material includes a portion sandwiched between the one member and the another member, and formed to extend from the buffer material.
