Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for attaching objects to surfaces using double-sided self-adhesive strips often fail to provide sufficient pressure, leading to air pockets and reduced bonding strength, especially on rough surfaces, which can result in peeling and failure of the holding device.
Innovation Solution
A method involving tilting and pressing an edge of the object onto the adhesive strip, reducing the contact area and increasing pressure, while displacing air pockets, ensuring maximum contact and improved adhesion, with optional rolling tilting movements to further enhance bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flat placement method is used to attach the holding body to the surface, then the application process is simple, but the contact pressure is insufficient and air pockets form reducing bonding strength
Solution Approach 1:
The attachment process is segmented into multiple sequential steps: first placing an edge of the holding body on the surface, then progressively tilting and pressing the body onto the adhesive strip. This segmentation allows pressure to be applied in a controlled manner from edge to base, ensuring complete contact and eliminating air pockets while maintaining operational simplicity
Solution Approach 2:
The method performs preliminary actions by first placing only an edge of the holding body on the surface before completing the full attachment. This preliminary placement establishes a stable starting point for the subsequent tilting and pressing movements, ensuring proper alignment and gradual pressure distribution to achieve maximum bonding strength
2Ease of operation
If pressure is applied uniformly across the entire adhesive strip, then the application process is straightforward, but air pockets remain trapped reducing effective bonding area
Solution Approach 1:
The method transitions from two-dimensional uniform pressure application to three-dimensional progressive pressure application. By tilting the holding body during attachment, pressure is applied sequentially from the edge through the intermediate region to the base, creating a pressure gradient that pushes air out and ensures complete contact across the entire adhesive surface, maximizing the effective bonding area
3Reliability
If the adhesive strip is fully covered immediately, then protection from environmental influences is achieved, but insufficient pressure results in poor wetting of the substrate
Solution Approach 1:
The method applies preliminary protective action by covering the adhesive strip with the holding body, but does so progressively through edge-first placement followed by tilting and pressing. This preliminary coverage protects the adhesive from environmental influences while the progressive pressure application ensures proper substrate wetting and bonding strength is achieved
4Strength
If high pressure is applied to ensure good bonding, then adhesive wetting is improved, but the risk of damaging the holding body or surface increases
Solution Approach 1:
The pressure application is segmented into progressive stages: initial edge placement with minimal pressure, followed by controlled tilting that gradually increases contact area and pressure, and finally gentle pressing to complete the bonding. This segmented approach ensures adequate adhesive wetting and bonding strength while distributing the mechanical load to prevent damage to the holding body or surface
