Insulation Wall Panel Staggered Reinforcement Ribs Delamination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing insulation wall panels, particularly those used in construction and refrigerated containers, face limitations due to vulnerability and delamination issues, which compromise their insulation value and mechanical integrity under varying forces.
Innovation Solution
The insulation wall panel design incorporates a central layer with core insulation panels and skin layers, reinforced by fibre-reinforced plastic layers and ribs, providing enhanced bending stiffness and shear resistance, and featuring staggered reinforcement ribs to minimize delamination and thermal bridging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a VIP panel is used for high insulation value, then thermal insulation performance is improved, but vulnerability to piercing and damage increases
Solution Approach 1:
The patent combines VIP panels with synthetic resin foam layers and fibre-reinforced plastic skin layers to create a composite wall structure. The VIP panels provide high thermal insulation where intact, while the foam and skin layers provide damage tolerance and structural protection, resolving the contradiction between high insulation performance and vulnerability to piercing.
2Strength
If reinforcement layers are added to increase bending stiffness, then mechanical strength is improved, but delamination between layers may occur
Solution Approach 1:
The patent introduces staggered reinforcement ribs as intermediary elements between the skin layers and core layers. These ribs act as mechanical connectors that distribute stresses and prevent delamination, allowing the reinforcement layers to provide bending stiffness without causing layer separation.
Solution Approach 2:
The reinforcement ribs extend in the thickness dimension of the wall panel, creating a three-dimensional reinforcement structure. This vertical reinforcement throughout the thickness provides bending stiffness while the staggered arrangement prevents planar delamination between layers.
3Strength
If continuous reinforcement is provided throughout the wall, then mechanical integrity is improved, but thermal bridging increases
Solution Approach 1:
The patent segments the reinforcement structure into discrete ribs rather than continuous layers. The staggered reinforcement ribs are separated by insulation panels and foam layers, creating thermal breaks between reinforcement elements. This segmentation maintains mechanical integrity through the rib structure while minimizing thermal bridging by interrupting continuous heat flow paths.
