Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for constructing bathrooms in high-rise buildings are either time-consuming and costly with cast-in-situ concrete or inefficient with prefabricated bathrooms lacking complete facilities and requiring complex installation procedures.
Innovation Solution
A prefabricated bathroom design featuring a structural wall with recessed top and bottom regions for concrete pouring, eliminating the need for protruding columns and bolts, and incorporating a glass reinforced plastic material layer for improved toughness and waterproofing, along with a method for constructing and installing that simplifies the process by connecting floors through reserve bars and concrete pouring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If cast-in-situ concrete frame is used to construct bathroom, then structural strength is improved, but construction period and cost increase significantly
Solution Approach 1:
The bathroom is divided into modular components (floor plate, wall panels, ceiling panel) that are precast separately and then assembled on-site. This segmentation allows parallel production of multiple components, significantly reducing construction time while maintaining structural integrity through standardized connection details.
Solution Approach 2:
Bathroom components are precast in controlled factory environments before delivery to the construction site. This preliminary action includes embedding connection elements (loops, protrusions, recesses) during manufacturing, eliminating the need for time-consuming on-site concrete casting and curing, thus accelerating the overall construction schedule.
2Loss of time
If conventional prefabricated bathroom is used, then construction period is reduced, but installation complexity and material cost increase
Solution Approach 1:
The connection elements (loops, protrusions, recesses) are integrated directly into the bathroom components during the precasting process. This merging of connection features with structural elements eliminates the need for separate installation hardware and complex assembly procedures, simplifying on-site installation while reducing material costs.
Solution Approach 2:
The precast bathroom components are designed with self-aligning and self-connecting features (complementary protrusions and recesses, embedded loops) that automatically guide and secure the assembly during installation. This self-service design reduces the need for specialized installation equipment and skilled labor, thereby reducing installation complexity.
3Manufacturing precision
If protruding columns with bolts are used for positioning and fixing, then positioning precision is improved, but device complexity and material cost increase
Solution Approach 1:
The protruding columns and external bolt systems are completely removed from the design. Instead, positioning precision is achieved through precisely formed recesses and protrusions that are integral to the bathroom components themselves. This extraction of external positioning elements simplifies the overall device complexity while eliminating the need for additional fastening materials.
Solution Approach 2:
Positioning precision is achieved through locally optimized geometric features (recesses and protrusions) at specific connection points rather than through a complex system of protruding columns and bolts across the entire structure. This localized approach maintains manufacturing precision while significantly reducing device complexity.
4Quantity of substance
If semi-prefabricated structural wall with small thickness is used, then material cost is reduced, but bearing capacity and waterproof performance deteriorate
Solution Approach 1:
The structural walls are constructed as composite elements combining precast concrete panels with integrated reinforcement (loops, protrusions, recesses) and waterproofing layers. This composite construction achieves adequate bearing capacity and waterproof performance while optimizing material usage and reducing overall material costs compared to traditional thick semi-prefabricated walls.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances bearing capacity, simplifies construction and installation, reduces material costs, and improves waterproof performance by eliminating the need for complex positioning and using fewer building materials, resulting in a more efficient and complete bathroom facility.
