Prefabricated Wall Panels with Integrated Utility Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional prefabricated modular building systems face challenges such as high material waste, reliance on non-renewable resources, and inefficient installation processes due to the weight and complexity of components, particularly in accommodating electrical, plumbing, and HVAC systems without requiring skilled labor or heavy machinery.
Innovation Solution
The development of prefabricated wall assemblies made from natural, rapidly renewable materials like wood chips, straw, or bamboo fibers, featuring trapezoidal corrugated panels with integrated horizontal and vertical channels for easy installation of conduits, reducing the need for threading or blocking and enabling vertical and horizontal placement of systems without specialized equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional prefabricated wall systems are used, then structural integrity is maintained, but installation complexity and time increase due to weight and lack of integrated channels
Solution Approach 1:
The patent combines multiple functions into a single wall panel component by integrating corrugated panels with built-in horizontal and vertical channels directly into the wall assembly structure. This allows electrical conduits, plumbing pipes, and HVAC ducts to be installed through pre-formed pathways without requiring separate blocking or threading operations, thereby reducing installation complexity and time while maintaining structural integrity.
Solution Approach 2:
The wall panel is segmented into functional zones with dedicated horizontal and vertical channels that divide the wall thickness into distinct pathways for different utility systems. This segmentation allows independent installation of electrical, plumbing, and HVAC systems within their respective channels without interfering with each other or the structural components.
2Loss of substance
If conventional lumber is used for prefabricated walls, then structural strength is achieved, but material waste and environmental impact increase
Solution Approach 1:
The patent employs composite construction by combining corrugated panels (which provide structural strength and rigidity) with integrated channels formed from the same material or compatible materials. This composite approach maintains the necessary structural strength while utilizing materials that can be more efficiently utilized with less waste compared to traditional lumber framing, which requires cutting and disposal of significant offcuts.
3Stability of the object's composition
If heavy prefabricated wall components are used, then structural stability is improved, but shipping and storage costs increase
Solution Approach 1:
The patent utilizes thin-walled corrugated panel construction that provides high structural stability relative to its weight. The corrugated geometry inherently provides strength and stiffness, allowing the walls to maintain structural integrity while using less material and weighing less than traditional solid lumber or concrete alternatives, thereby reducing shipping and storage costs.
4Loss of time
If electrical and plumbing systems are installed after wall assembly, then structural integrity is maintained, but installation time and labor costs increase
Solution Approach 1:
The patent incorporates channels for electrical conduits, plumbing pipes, and HVAC ducts directly into the wall panel structure during manufacturing. This preliminary action allows utility systems to be installed concurrently with or before wall assembly, eliminating the need for post-installation drilling, blocking, or threading operations, thereby significantly reducing installation time and labor costs while maintaining structural integrity.

AI summary
Prefabricated wall assemblies for the construction of buildings have a corrugated panel and preferably include at least one backside panel. The corrugated panel has one or more vertical channels and several horizontal channels. The vertical channels extend the entire panel height and are recessed from the front face. The horizontal channels extending the entire panel width and are also recessed from the front face so they intersect with the vertical channel. The horizontal channels are almost as wide as the vertical channels, and are greater than one-half the vertical channel width. The backside panel is connected to the corrugated panel to form a structural panel assembly. The backside panel can be a shear panel or other backside flat panel, a backside corrugated panel symmetrically mirroring the corrugated panel, a backside corrugated panel asymmetrically mirroring the corrugated panel, a sandwiched corrugated panel, a relief panel or any combination thereof.
