Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building panel systems fail to provide a sustainable, energy-efficient, and airtight solution for extreme weather conditions while maintaining structural integrity and resisting infestation, often relying on additional membranes and sealants that can fail over time.
Innovation Solution
A building panel assembly featuring a pair of spaced-apart containment boards separated by an inner insulating core, utilizing a lightweight structural steel frame with 'Z' joints and MgO board splines for enhanced airtightness and load-bearing capacity, eliminating the need for additional membranes and sealants, and minimizing thermal bridging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional membranes and sealants are used to provide moisture control and airtightness, then the building envelope performance is improved, but the reliability deteriorates over time due to failure of these materials and poor installation techniques
Solution Approach 1:
The patent merges the airtightness function directly into the panel assembly structure itself, eliminating the need for separate membranes and sealants. The panel edges are designed with integrated sealing features that provide airtightness as an inherent property of the assembly rather than through additional components.
Solution Approach 2:
The patent extracts and eliminates the separate membranes and sealants from the building envelope system. By removing these additional components, the design achieves airtightness through the core panel assembly alone, reducing complexity and improving reliability by removing potential failure points.
2Strength
If standard SIPS panels or timber frame panels are used, then the construction is simpler, but the load-bearing capacity is insufficient for additional loadings without additional structural elements
Solution Approach 1:
The patent designs the panel assembly to serve multiple functions simultaneously: the same structural components provide both the load-bearing capacity for additional loadings and the basic panel construction functions. The integrated design eliminates the need for separate structural reinforcement elements.
3Ease of manufacture
If non-treated timber and OSB are used as building materials, then the ease of manufacture is improved, but the resistance to infestation deteriorates
Solution Approach 1:
The patent employs composite material construction where the panel assembly combines multiple materials with complementary properties. The design integrates materials that provide both ease of manufacture and inherent resistance to infestation, creating a composite system that overcomes the weaknesses of individual materials.
