Vacuum Insulation Panel With Elastic Foam For Curved Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum insulation panels fail to provide a sufficient insulating effect, especially when applied to curved surfaces with irregularities or when using thick pressure-sensitive adhesive tapes, leading to gaps and reduced thermal performance.
Innovation Solution
A board-like vacuum insulation panel with an elastic body, where the elastic body has a high degree of elongation and specific hardness, is attached to the application surface, ensuring close contact and minimizing gaps between the panel and the surface, using materials like flexible polyurethane foam or melamine foam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a vacuum insulation panel is bonded to a curved application surface using conventional methods, then the panel can be applied to curved surfaces, but sufficient insulating effect cannot be obtained due to gaps and wrinkles
Solution Approach 1:
The patent applies a flexible adhesive layer between the vacuum insulation panel and the curved surface. This adhesive layer can deform and conform to irregular surfaces, filling gaps and preventing wrinkles from forming. The flexible nature of the adhesive allows the rigid vacuum insulation panel to be bonded to curved surfaces while maintaining continuous contact and eliminating air pockets that would compromise thermal insulation.
2Strength
If a thick double-coated pressure-sensitive adhesive tape is used to bond the vacuum insulation panel, then bonding strength is improved, but sufficient insulating effect is still hardly obtained due to gaps and irregularities
Solution Approach 1:
The patent introduces a flexible adhesive layer as an intermediary substance between the vacuum insulation panel and the application surface. This adhesive mediator not only provides bonding strength to attach the panel but also fills irregularities and gaps, creating a continuous thermal barrier. The adhesive layer acts as a bridge that simultaneously achieves mechanical attachment and thermal insulation, eliminating the need to compromise between bonding strength and insulating effect.
3Shape
If the vacuum insulation panel is bonded as curved along the application surface, then it can conform to the surface shape, but wrinkles and folds are formed that reduce insulating performance
Solution Approach 1:
The flexible adhesive layer allows the rigid vacuum insulation panel to conform to curved surfaces without forming wrinkles or folds. The adhesive absorbs the geometric mismatch between the flat panel and curved surface, maintaining continuous contact while preventing the panel material from buckling or folding. This eliminates air pockets and maintains the integrity of the thermal insulation barrier.
