Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stick frame construction methods in building design face challenges in enhancing the shear strength of vertical wall components, leading to potential racking and structural damage from in-plane lateral forces such as wind and earthquakes.
Innovation Solution
A modular stiff wall panel assembly featuring a continuous unitary layer with statically engaged studs and reinforcement members, including external and internal hat-shaped reinforcement members, providing improved resistance to shear, racking, and impact forces through a specifically configured structural design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If standard stick frame construction is used, then the structure is lightweight and easy to construct, but the shear strength of vertical wall components is insufficient leading to racking damage
Solution Approach 1:
The wall panel is divided into modular components including a frame assembly, sheathing panel, and separate reinforcement members that can be independently manufactured and then assembled together, allowing for simplified production while achieving enhanced shear strength through the systematic arrangement of these segments
Solution Approach 2:
The wall panel assembly combines multiple materials and components including wood or metal studs, sheathing panels, and reinforcement members with hat-shaped cross-sections to create a composite structure that achieves superior shear strength and racking resistance compared to individual materials alone
2Strength
If reinforcement members are added to increase shear strength, then resistance to racking forces improves, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The reinforcement members are designed to be statically engaged with the frame assembly and sheathing panel, where the hat-shaped cross-sections provide inherent structural stability and the modular design allows for self-aligning assembly that reduces manufacturing and installation complexity
Solution Approach 2:
The reinforcement members with hat-shaped cross-sections serve multiple functions including providing shear strength, resisting racking forces, and offering attachment surfaces for other building components, thereby achieving enhanced performance without proportionally increasing manufacturing complexity
3Strength
If a modular wall panel assembly with multiple components is used, then shear strength and impact resistance improve, but the quantity of materials and assembly complexity increase
Solution Approach 1:
The frame assembly, sheathing panel, and reinforcement members are combined into a pre-assembled modular wall panel unit that provides enhanced shear strength and impact resistance while reducing the total quantity of separate materials needed compared to traditional stick frame construction requiring individual studs, plates, and bracing elements

AI summary
A modular stiff wall panel assembly, for a building structure, includes a modular wall panel including a body having a single, continuous, and unitary layer extended along an entire surface area of the wall panel, a plurality of studs engaged with the single, continuous, and unitary layer, a plurality of external reinforcement members engaged with the single, continuous, and unitary layer, and a plurality of internal reinforcement members engaged with the studs and oppositely spaced from the external reinforcement members. Each of the external reinforcement members and the internal reinforcement members have a hat-shaped (profile) cross-section.
