Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional building wall constructions lack an integrated solution that provides both strong internal surfaces and effective thermal and sound insulation, while also being environmentally friendly and cost-effective.
Innovation Solution
A composite insulated wall panel is developed, featuring a skin layer composed of at least 50% glass fibers with a tensile strength of 50 MPa and modulus of elasticity of 3 GPa, integrated with a cellulose fiber insulation board, which is manufactured using a modified sheet molding compound process, incorporating resin, chopped glass fibers, and cellulose fibers from recycled palm tree materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional building wall constructions are used, then structural strength is provided, but thermal insulation and sound insulation are insufficient
Solution Approach 1:
The patent applies composite materials by combining a skin layer containing glass fibers with a cellulose fiber insulation board to create an integrated wall panel. This composite structure provides both structural strength from the skin layer and thermal/sound insulation from the cellulose core, resolving the contradiction between strength and insulation performance.
2Strength
If traditional building wall constructions are used, then structural strength is provided, but integrated interior surface and insulation are lacking
Solution Approach 1:
The patent merges multiple traditional wall components (structural layer, insulation layer, interior surface) into a single integrated composite panel. The skin layer with glass fibers serves as both structural element and interior surface, while the cellulose fiber board provides insulation, eliminating the need for separate layers and simplifying construction.
3Loss of energy
If conventional insulation materials are used, then insulation performance is achieved, but environmental friendliness and recyclability are reduced
Solution Approach 1:
The patent uses cellulose fiber insulation board made from recycled materials, enabling recovery and reuse of natural fibers. The cellulose board can be recycled or biodegraded at end-of-life, contrasting with conventional insulation materials that are difficult to recycle, thus improving environmental friendliness while maintaining insulation performance.

AI summary
A building wall includes an exterior surface and an interior surface. The exterior surface faces the exterior of the building and the interior surface faces an interior room of the building. The wall has a total wall thermal resistance between the exterior surface and the interior surface. The wall includes a structural member positioned between the exterior surface and the interior surface, and the structural member is configured to bear at least a portion of a vertical load of the wall. An insulated composite wall panel is positioned between the structural member and the interior surface. The insulated composite wall panel includes a skin layer including glass fibers and a cellulose fiber insulation board attached with a resin to a first surface of the skin layer. The thermal resistance of the cellulose fiber insulation board comprises the greatest component of the total wall thermal resistance.
