Prefabricated Module With Pre-Assembled Wet Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing prefabricated building systems are costly and time-consuming to assemble, as they require extensive on-site work to complete interior installations, making them inefficient for modern construction projects that demand low-cost and rapid completion.
Innovation Solution
A method of prefabricating modules with pre-assembled wet areas and technical installations, using a two-shaft arrangement and pre-mounted engagement means, allowing for efficient space utilization and accurate positioning, which can be easily connected with prefabricated panels or slabs to form multi-room buildings efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If prefabricated modules are used for building construction, then construction speed is improved, but on-site work complexity increases due to extensive interior installation requirements
Solution Approach 1:
The patent applies preliminary action by pre-assembling wet areas (bathrooms, kitchens) and technical installations (plumbing, electrical, ventilation) within the modules during factory production. This includes installing waterproof layers, pipes, conduits, and equipment before the modules are transported to the construction site, thereby reducing on-site installation complexity while maintaining high construction speed
Solution Approach 2:
The building is divided into standardized modular units that can be independently manufactured and assembled. Each module is segmented into functional areas (wet areas, dry areas, technical shafts) that can be pre-equipped separately, allowing parallel production and simplifying on-site assembly through standardized connection interfaces
2Adaptability or versatility
If traditional prefabricated modules with extensive on-site work are used, then design flexibility is maintained, but construction costs increase due to extensive labor requirements
Solution Approach 1:
The patent creates universal module designs with standardized dimensions, connection interfaces, and configurable interior layouts. The same basic module type can be adapted for different building purposes (hotels, apartments, hospitals) by reconfiguring partitions and equipment, maintaining design flexibility while enabling economies of scale in manufacturing that reduce construction costs
3Loss of time
If modules with complete interior installations are prefabricated, then on-site construction time is reduced, but module complexity and manufacturing difficulty increase
Solution Approach 1:
The module is segmented into distinct functional zones (wet areas, dry areas, technical shafts) that can be manufactured and pre-equipped separately in the factory. This segmentation allows specialized teams to work on different areas simultaneously, managing complexity while enabling complete interior installations to be completed before delivery, thereby reducing on-site construction time

AI summary
A prefabricated module has four walls extending between a floor and a roof to form a rectangular cuboid shape, within which interior equipment is provided and connected to technical installations (12). The module (2) has a wet area (10), in which waterproof layers are provided on the interior walls and floor surfaces of the rectangular cuboid shape.
