Peelable Adhesive Shim for Variable Gap Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shims are specifically designed for fixed gaps between two parts, limiting their adaptability to varying gaps, as they are manufactured with a fixed shape compatible only with a specific space.
Innovation Solution
A wedge composed of multiple peelable sections formed by stacking sheets with an adhesive layer, featuring slots that allow for the removal and adjustment of sheets, enabling the wedge to adapt to varying gaps between surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional shims are manufactured with a fixed shape for a specific gap, then manufacturing precision is improved, but adaptability deteriorates
Solution Approach 1:
The shim is divided into multiple individual sheets stacked together, where each sheet can be independently removed. This segmentation allows the shim to be customized for different gap sizes by adjusting the number of sheets, thereby resolving the contradiction between manufacturing precision and adaptability.
Solution Approach 2:
The shim transitions from a static fixed-configuration structure to a dynamic adjustable structure. The ability to add or remove sheets dynamically allows the shim to adapt to varying gap requirements while maintaining precise fit for each specific configuration.
2Reliability
If conventional shims are designed for specific applications, then reliability is improved, but ease of operation deteriorates
Solution Approach 1:
By segmenting the shim into removable sheets, the system maintains reliable gap filling through proper sheet selection while dramatically improving ease of operation. Users can easily adjust the shim by adding or removing sheets without requiring specialized tools or complex procedures.
Solution Approach 2:
The shim system enables self-service adjustment where users can independently modify the gap filling capability by removing or adding sheets as needed, eliminating the need for professional intervention or specialized adjustment mechanisms.
3Adaptability or versatility
If multiple fixed-configuration shims are manufactured for different gaps, then adaptability is improved, but device complexity increases
Solution Approach 1:
Multiple potential shim configurations are merged into a single stackable system. Instead of maintaining separate shims for different gap sizes, the invention combines them into one adjustable shim composed of stackable sheets, reducing overall system complexity while maintaining full adaptability.
Solution Approach 2:
A single shim system performs multiple functions by accommodating various gap sizes through sheet removal. This universal design eliminates the need for multiple specialized shims, thereby reducing device complexity while expanding adaptability.
