Modular House Inner Wall Construction Integrating Insulation and Wallpapering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for constructing inner walls of modular houses prolong the construction period and increase costs due to separate installation of insulation materials and wallpapering, which cannot meet the urgent demand for container houses like COVID-19 quarantine accommodations.
Innovation Solution
A method involving the installation of a temporary inner wall in a container framework, filling the gap with heat-insulating foamed resin, and curing it while moving the wall, allowing simultaneous insulation and wallpapering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If insulation materials are installed separately and then wallpapering is performed separately, then the construction quality is maintained, but the construction period is prolonged and construction costs increase
Solution Approach 1:
The patent combines the insulation material installation and wallpapering processes into a single integrated operation. The wallpapering unit performs both functions simultaneously by installing insulation materials and applying wallpaper in one continuous process, eliminating the sequential separation of these tasks and thereby reducing construction time and improving productivity
Solution Approach 2:
The patent applies preliminary action by pre-coordinating the insulation material installation with the subsequent wallpapering process. The system prepares and positions insulation materials in advance within the integrated unit, so that when wallpapering begins, the insulation materials are already in place, allowing both operations to proceed efficiently without interruption or delay
2Ease of manufacture
If separate labor is required for installing insulation materials and wallpapering, then each task can be performed by specialists, but construction costs increase
Solution Approach 1:
The patent implements universality by designing the wallpapering unit to perform multiple functions: it can install insulation materials, apply wallpaper, and complete finishing work all through a single integrated system. This multi-functional approach eliminates the need for separate specialized labor forces for each task, reducing overall labor resource requirements while maintaining construction quality
Solution Approach 2:
The patent merges the previously separate insulation installation and wallpapering operations into a single unified process performed by one integrated unit. This consolidation reduces the total quantity of labor resources needed by eliminating redundant setup, movement, and coordination between separate work teams
3Productivity
If conventional sandwich panels are used for temporary buildings, then the buildings can be manufactured with conventional methods, but the installation speed is slow and relocation is difficult
Solution Approach 1:
The patent applies segmentation by dividing the construction process into modular, standardized units that can be manufactured separately and assembled quickly on-site. The container framework and inner wall structures are segmented into discrete components that facilitate rapid installation while maintaining the ability to disassemble and relocate the building
Solution Approach 2:
The patent implements dynamics by designing the modular house structure to be adaptable and reconfigurable. The standardized components and framework allow the building to be easily assembled, disassembled, and relocated, providing dynamic flexibility that contrasts with conventional fixed construction methods
