Vacuum Insulation Panel Bonding Structure for Wind Pressure Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vacuum insulation panels using glass fiber cores do not meet the required wind pressure resistance performance necessary for building materials, especially under high wind speeds, as they lack sufficient strength and section modulus to withstand external pressures.
Innovation Solution
A method for manufacturing vacuum insulation panels that incorporates a foam core with open cells within a hollow body, where the inner surfaces of the hollow body are adhered to the core material using an adhesive layer, such as water glass, to enhance the structural integrity and achieve improved wind pressure resistance by increasing the section modulus equivalent to a single thick plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glass fiber is used as core material and packed with resin film or stainless steel plate, then vacuum insulation performance is achieved, but wind pressure resistance performance is insufficient
Solution Approach 1:
The patent uses a composite structure combining hollow body (resin or metal) with core material (glass fiber, foam, or powder) to create a sandwich panel configuration. This composite structure increases the section modulus and wind pressure resistance while maintaining vacuum insulation performance. The hollow body acts as a structural shell that provides the necessary strength against external wind pressures.
Solution Approach 2:
The patent divides the panel into distinct functional layers: a hollow body shell providing structural strength, a core material providing insulation, and vacuum space providing thermal barrier. This segmentation allows each component to optimize its specific function while collectively achieving both wind pressure resistance and insulation performance.
2Reliability
If hollow body and core material are not adhered, then manufacturing process is simple, but structural integrity and wind pressure resistance are insufficient
Solution Approach 1:
The patent introduces an adhesive layer as an intermediary substance between the hollow body inner surface and the core material surfaces. This adhesive mediator creates strong bonding that integrates the structural shell with the insulation core, ensuring the panel acts as a unified structure capable of withstanding wind pressures while maintaining manufacturing feasibility.
3Strength
If panel thickness is increased to improve wind pressure resistance, then section modulus increases, but manufacturing complexity and cost increase
Solution Approach 1:
The patent transitions from a solid thick panel design to a hollow sandwich structure, effectively utilizing the third dimension by creating internal void space. This hollow body configuration provides high section modulus and wind pressure resistance without increasing overall panel thickness, as the structural strength comes from the hollow shell geometry rather than material thickness alone.
