Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current adhesive audit methods using painter's tape are time-consuming and inaccurate, especially with aggressive bonding adhesives that stick to the tape, making it difficult to determine the optimal adhesive application amount.
Innovation Solution
A kit containing a water-based release coating with polydimethyl siloxane, which can be applied to substrates to facilitate easy removal of adhesives, allowing for faster and more accurate adhesive audits by enabling easy separation without leaving residue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If painter's tape is used for adhesive audit, then adhesive application amount can be determined, but the process is time consuming and inaccurate with aggressive bonding adhesives
Solution Approach 1:
The patent introduces painter's tape as an intermediary material between the substrate and the adhesive. The tape provides a controlled release surface that allows aggressive bonding adhesives to be applied and then easily removed, solving the problem of adhesive sticking to the substrate during the audit process. This intermediary layer enables both accurate measurement and time efficiency.
Solution Approach 2:
The patent uses disposable painter's tape that is applied to the substrate, allows adhesive application, and then is removed and discarded after the adhesive is transferred to it. This disposable approach eliminates the need for cleaning and reuse, significantly reducing the time required for repeated adhesive audits while maintaining measurement accuracy.
2Ease of operation
If painter's tape is used for adhesive audit, then adhesive can be removed for weighing, but aggressive bonding adhesives stick to the tape making removal difficult
Solution Approach 1:
The painter's tape acts as an intermediary with specific adhesive properties that allow aggressive bonding adhesives to bond strongly during application, then release easily during removal. The tape's surface characteristics enable controlled adhesion - strong enough to hold the adhesive during the bonding process, but allowing easy removal for accurate weighing and measurement.
3Loss of time
If release coating is applied to facilitate adhesive removal, then audit time is reduced, but the coating must maintain substrate integrity during bonding
Solution Approach 1:
The release coating is applied locally only to the specific areas where adhesive will be applied, rather than covering the entire substrate. This localized application allows the coating to facilitate easy adhesive removal in the bonded areas while leaving other areas of the substrate intact and maintaining overall substrate integrity and strength during the bonding process.
Solution Approach 2:
The release coating serves as an intermediary layer between the substrate and adhesive that enables easy separation after bonding. It provides the necessary release properties to reduce audit time while being applied in a controlled manner that maintains the structural integrity of the bonded article during the bonding process.
