Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Insulating containers made from polymers face challenges in achieving effective adhesion between molded polymeric surfaces and additional insulating materials, leading to reduced thermal resistivity due to debonding or delamination, which diminishes their thermal insulation performance.
Innovation Solution
The method involves introducing ozone gas with a concentration of 5-7.5% into the internal cavity of the insulating container, displacing air, and then flushing it out with air to create improved surface functionalization for better adhesion of insulating foam to the molded polymeric surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If insulating containers are made from polymers with molded structures, then manufacturing efficiency and structural integrity are improved, but adhesion between molded polymeric surfaces and additional insulating materials deteriorates, leading to debonding and reduced thermal resistivity
Solution Approach 1:
The patent applies preliminary action by treating the molded polymeric surface with ozone gas before the insulating material is applied. This preliminary surface treatment modifies the polymer surface properties to enhance adhesion, preventing debonding while maintaining the efficiency of molded construction. The ozone treatment is performed as a preliminary step in the manufacturing process.
Solution Approach 2:
The patent utilizes parameter changes by altering the surface properties of the polymeric material through ozone gas treatment. This changes the surface energy, chemistry, or other surface parameters to improve wettability and adhesion of the insulating material, resolving the contradiction between manufacturing efficiency and adhesion reliability.
2Strength
If ozone gas is introduced into the internal cavity to improve adhesion, then bonding strength between polymer and foam is enhanced, but process complexity increases
Solution Approach 1:
The patent employs an intermediary approach by using ozone gas as a mediator between the molded polymeric surface and the insulating material. The ozone gas facilitates improved adhesion without requiring complex mechanical fastening systems or additional chemical adhesives, thus enhancing bonding strength while limiting the increase in process complexity.
