Solution Overview

Problem

Traditional building skin systems for external wall panels are limited by weight, cost, and assembly time, often requiring additional structural members to comply with design code requirements, which increases weight and complexity.

Innovation Solution

A prefabricated building skin system comprising a composite external wall panel with a fiber-reinforced polymer wrapping around a foam core, integrated steel connectors, and thermoset resin, allowing for self-supporting, lightweight panels that can span between columns without additional structural members, and can be finished with various aesthetic options like brick or paint.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional skin systems use additional structural members to satisfy code requirements, then the panels can meet design code requirements, but the weight of the external skin system increases

Engineering Contradiction:
Improvecompliance with design code requirementsVSAvoidweight of external skin system
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The patent combines multiple functions into a single integrated wall panel system. The composite panel integrates structural support, cladding, and code-compliance features (such as fire rating, insulation, and structural strength) into one unified component, eliminating the need for separate structural members while meeting all design code requirements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent uses composite materials in the wall panel construction, combining different materials (such as concrete, steel reinforcement, insulation layers, and cladding materials) to create a multi-functional panel that achieves structural strength, thermal insulation, fire resistance, and aesthetic cladding functions simultaneously, thereby reducing overall weight while meeting code requirements.

Inventive Principle:
Principle #40Composite materials

2Strength

If traditional skin systems use additional structural members to support cladding, then the panels can react loads during assembly and service, but the complexity of the system increases

Engineering Contradiction:
Improveability to react loadsVSAvoidcomplexity of wall panel system
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The patent merges the load-bearing structural function and the cladding function into a single integrated wall panel. The composite panel design incorporates structural reinforcement directly within the panel assembly, allowing it to react loads during assembly, transportation, installation, and service without requiring external structural members, thereby simplifying the overall system.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If traditional skin systems require multiple different components, then the panels can satisfy various design code requirements, but the assembly time increases

Engineering Contradiction:
Improvecompliance with design code requirementsVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-assembling and pre-integrating all necessary components (structural elements, insulation, cladding, and code-compliance features) into complete wall panels at the manufacturing site before transportation. This off-site prefabrication allows for quality control and code compliance verification to be completed beforehand, significantly reducing on-site assembly time while maintaining all required code standards.

Inventive Principle:
Principle #10Preliminary action
