Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing prefabricated walls are complex to disassemble and reassemble, require numerous construction workers, and have lengthy construction periods due to their intricate structures and reliance on screws, making maintenance and modifications difficult.
Innovation Solution
A prefabricated wall system with vertically installed studs and runners, featuring elastic coupling members that minimize the use of screws by allowing the finishing panel to be easily coupled and decoupled from the studs, enabling quick installation and disassembly, and allowing a small number of personnel to perform the work, with additional features like gappers and column assemblies for flexible wall configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional prefabricated walls use numerous members and screw connections for structural stability, then the wall strength and stability are improved, but the complexity of disassembly and reassembly increases significantly
Solution Approach 1:
The wall system is divided into modular components (studs, finishing panels, coupling members) that can be independently assembled and disassembled. The coupling member is segmented into an inserting portion that engages with the stud and a panel fixing portion that secures the finishing panel, allowing for easy separation without damaging components.
Solution Approach 2:
The screw connection is extracted and replaced with a coupling member that uses mechanical interlocking through coupling grooves. This removes the need for screws and screwdrivers, enabling tool-free assembly and disassembly while maintaining structural integrity through the elastic deformation of the coupling member.
2Device complexity
If traditional prefabricated walls require many construction workers for assembly, then the structural complexity can be managed, but the construction time and labor costs increase
Solution Approach 1:
Multiple functions are merged into single components: the coupling member simultaneously provides structural connection, positioning, and securing functions; the stud integrates the frame structure with built-in coupling grooves; the finishing panel combines the cladding function with integrated coupling features. This reduces the number of separate parts and simplifies assembly operations.
Solution Approach 2:
The coupling member performs self-alignment and self-securing through its elastic properties. When the inserting portion is inserted into the coupling groove, the elastic deformation automatically creates a secure connection without requiring additional fastening operations or multiple workers for positioning and securing.
3Stability of the object's composition
If traditional prefabricated walls use fixed construction procedures, then the structural integrity is maintained, but the adaptability to different site conditions and modifications decreases
Solution Approach 1:
The wall system transitions from a fixed, rigid assembly to a dynamic, adjustable configuration. The elastic coupling member allows for controlled deformation and reconfiguration, enabling the wall to adapt to different installation conditions, heights, and positioning requirements while maintaining structural integrity through the elastic recovery of the coupling member.
Solution Approach 2:
The coupling groove and inserting portion design provides universal compatibility across different wall sections and configurations. The same coupling mechanism works for various stud positions, panel sizes, and wall heights, allowing the system to be adapted to different site conditions and modification requirements without changing the fundamental connection method.
