Pre-manufactured Utility Wall Assembly for Multi-story Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional construction methods involve time-consuming and costly installation of individual utility components in building construction, requiring coordination of various trades and exposing components to undesirable elements.
Innovation Solution
Pre-manufactured utility walls are assembled with pre-plumbed, pre-wired, and prefinished components, allowing for efficient consolidation and rapid installation of utilities by grouping normal utility components into a single standardized component, which can be vertically stacked for multi-story buildings, incorporating features like metal studs, insulation, and weather-resistant barriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual utility components are installed during final phases of building construction, then utilities can be connected to main supply and waste resources, but installation is time-consuming and costly
Solution Approach 1:
The patent applies preliminary action by pre-assembling utility components (plumbing, electrical, HVAC) into complete wall assemblies at a manufacturing facility before delivery to the construction site. This allows utility installation to occur during wall assembly installation rather than during final building phases, significantly reducing on-site installation time while maintaining connection reliability through factory-controlled precision.
Solution Approach 2:
The patent merges multiple separate utility components and trades into a single integrated wall assembly. By combining plumbing pipes, electrical wiring, HVAC ducts, and structural framing into one pre-assembled unit, the patent eliminates the need for sequential installation by multiple trades, reducing both time and coordination complexity while ensuring reliable utility connections through factory-quality assembly.
2Reliability
If various trades coordinate utility installation during construction, then utilities can be properly installed, but coordination is difficult and construction proceeds piecemeal
Solution Approach 1:
The patent merges the functions of multiple trades (plumbing, electrical, HVAC, framing) into a single integrated wall assembly manufactured in a controlled facility. This eliminates the coordination complexity of managing multiple separate trades on-site while maintaining high installation quality through factory-controlled assembly processes and quality assurance protocols.
Solution Approach 2:
The wall assembly serves multiple functions simultaneously: structural support, utility distribution, and building envelope functions. By designing a universal assembly that incorporates all these functions, the patent eliminates the need for separate installations by different trades, reducing coordination complexity while ensuring reliable utility installation through integrated design.
3Productivity
If utility components are exposed during construction, then installation can proceed, but components are exposed to undesirable elements
Solution Approach 1:
The patent applies preliminary action by completing utility component installation and protection measures during factory assembly before the components are exposed to the construction environment. Utility pipes, wiring, and ducts are installed and sealed within the wall assembly in a controlled facility, protecting them from environmental elements during transport and installation while maintaining installation speed through the pre-assembled nature of the unit.
Solution Approach 2:
The patent uses protective barriers and sealants during factory assembly to shield utility components from environmental exposure. The wall assembly itself acts as a protective shell, enclosing utility components within the insulated wall cavity, preventing exposure to undesirable elements during both construction and operation while allowing rapid installation of the complete protected assembly.
