Moisture-Curing Adhesive for Watertight Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for bonding and repairing household articles and structures lack safety and ease of use for consumers, and often require welding or other complex assembly techniques, especially for applications like underwater repairs and assembling all-terrain vehicles.
Innovation Solution
A flexible polymer-based adhesive composition is applied to various surfaces, allowing for strong, watertight bonds without the need for welding, and can be tested for strength by suspending weighted blocks or used underwater for repairs, enabling assembly and repair of diverse items including all-terrain vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional bonding methods are used, then assembly and repair can be achieved, but the process is complex and requires welding or specialized techniques
Solution Approach 1:
The patent replaces complex mechanical assembly systems (welding, specialized tools) with a simple adhesive-based bonding system that consumers can easily apply. The adhesive composition eliminates the need for welding equipment and complex assembly procedures, making the bonding process accessible to consumers while maintaining structural integrity.
Solution Approach 2:
The adhesive composition is designed to be self-sufficient, requiring no specialized equipment or complex procedures. Consumers can directly apply the adhesive to bond surfaces together, and the adhesive performs all necessary bonding functions automatically, eliminating the need for professional assembly techniques or specialized tools.
2Adaptability or versatility
If adhesive is applied to underwater surfaces, then underwater repairs can be performed, but bond strength testing becomes challenging
Solution Approach 1:
The patent introduces a controlled environment as an intermediary for bond strength testing. By testing the adhesive bond in a controlled laboratory setting rather than directly in underwater conditions, the patent can accurately measure bond strength while still demonstrating the adhesive's capability for underwater applications. The controlled environment serves as a mediator that enables reliable measurement without requiring complex underwater testing equipment.
3Strength
If significant weight is suspended from bonded blocks, then bond strength is demonstrated, but the adhesive must maintain integrity over extended periods
Solution Approach 1:
The patent utilizes parameter changes in the adhesive composition to achieve both immediate bond strength and long-term durability. The adhesive formulation includes moisture-curing components that activate upon contact with moisture, creating a strong bond rapidly while continuing to cure and strengthen over extended periods. This parameter change approach allows the adhesive to provide immediate structural support for weight suspension while continuously improving bond integrity over time.
