Composite Wall Panels with Integrated Conduit Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional prefabricated building systems are inefficient due to their weight, material waste, and the need for skilled labor and specialized equipment for installation, particularly when incorporating electrical, plumbing, and HVAC systems, and they often fail to accommodate vertical and horizontal installations effectively.
Innovation Solution
A prefabricated wall assembly made from waste agricultural and forestry materials like wood chips, straw, and bamboo fibers, featuring trapezoidal corrugated panels with integrated channels for vertical and horizontal conduit installation, allowing for easy assembly and integration with existing structures without the need for complex threading or blocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional prefabricated walls made from 2x4 studs are used, then structural strength is achieved, but weight increases making installation inefficient and requiring skilled labor
Solution Approach 1:
The patent changes the material parameters from traditional wood studs to composite panels made from agricultural waste materials bound with polymeric adhesive. This material substitution reduces weight while maintaining structural integrity through the engineered composite structure with integrated channels.
Solution Approach 2:
The wall panels are constructed as composite materials combining agricultural waste fibers (corn stalks, husks, stover) with polymeric adhesive binders. This composite approach creates a lightweight yet structurally sound material that replaces traditional heavy wood studs while providing integrated conduit channels.
2Ease of manufacture
If standard lumber is used for prefabricated walls, then construction is simplified, but material waste increases depleting natural resources
Solution Approach 1:
The patent converts agricultural waste materials (corn stalks, husks, stover) that would normally be discarded or burned into valuable building materials. This transforms harmful waste disposal practices into a beneficial resource utilization process, reducing both waste and depletion of virgin natural resources.
Solution Approach 2:
Instead of discarding agricultural byproducts, the patent recovers and reuses these materials in wall panel construction. The agricultural waste fibers are processed and bound with polymeric adhesive to create structural panels, thereby recovering value from materials that would otherwise be discarded.
3Strength
If prefabricated walls are made heavier for structural integrity, then strength is improved, but shipping and storage costs increase
Solution Approach 1:
The patent changes the density parameter of wall materials by using lightweight agricultural waste fibers combined with polymeric adhesive, creating panels that achieve required structural integrity at lower weight. This reduces the quantity of material that needs to be shipped and stored while maintaining strength.
Solution Approach 2:
The composite construction using agricultural fibers and polymeric binders creates a material with optimized strength-to-weight ratio. This composite structure provides necessary structural integrity while minimizing weight, thereby reducing shipping and storage requirements and associated costs.
4Adaptability or versatility
If electrical and plumbing systems are installed in traditional prefabricated walls, then functionality is achieved, but installation time increases requiring drilling and threading
Solution Approach 1:
The patent merges the structural wall panels with integrated conduit channels into a single composite unit. The channels for electrical and plumbing systems are built into the wall panels during manufacturing, eliminating the need for separate drilling and threading operations during installation and significantly reducing installation time.
Solution Approach 2:
The conduit channels are prepared in advance during panel manufacturing rather than during on-site installation. This preliminary action of pre-forming the channels allows for rapid installation of electrical and plumbing systems without time-consuming drilling and threading operations.

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 channel width of the vertical channel. 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, or any combination thereof.
