Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The automotive industry faces challenges in applying taped seal constructions to vehicle body parts efficiently and quickly, particularly during manual application in series production or small series production, where existing methods are time-consuming and labor-intensive.
Innovation Solution
A taped seal construction featuring a seal with a main portion and a lip portion, attached to a tape with a split liner that allows for easy positioning and correction before full attachment, utilizing a heat-activatable adhesive layer and a pressure-sensitive adhesive layer for secure bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a taped seal construction with a solid liner is used, then the seal provides strong adhesion to the body part, but the application process becomes time-consuming and cannot be easily positioned or corrected
Solution Approach 1:
The liner is divided into a first removable portion and a second removable portion, allowing the tape to be applied in stages. The first portion is removed to expose adhesive for initial positioning, then the seal is applied and positioned. The second portion is removed to expose additional adhesive for final bonding, enabling both easy positioning and strong adhesion.
2Reliability
If a taped seal construction with a solid liner is used, then the seal provides strong adhesion, but the position cannot be corrected after application
Solution Approach 1:
The liner is segmented into removable portions that allow the operator to expose adhesive selectively. The first removable portion is removed to allow positioning adjustments, and only after the seal is correctly positioned is the second removable portion removed to finalize the bonding, thus providing both positioning flexibility and strong adhesion.
Solution Approach 2:
The first removable portion of the liner is removed in advance to expose the adhesive layer, allowing the seal to be positioned and adjusted before final application. This preliminary exposure of adhesive enables positioning corrections before the seal is permanently bonded.
3Ease of operation
If manual application of taped seals is used, then flexibility in positioning is achieved, but the process is labor-intensive and slow
Solution Approach 1:
The liner is divided into a first removable portion and a second removable portion, enabling a streamlined manual application process. The first portion is removed for positioning, the seal is applied and positioned efficiently, then the second portion is removed for final bonding. This segmentation reduces steps and improves productivity while maintaining positioning flexibility.
