Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bolted connections in prefabricated component assembly fail to provide high-strength connections and are cumbersome, leading to low construction efficiency due to high shearing forces and bending moments.
Innovation Solution
A connection assembly comprising C-shaped groove members and an H-shaped connection member with wedge members and high-strength cement slurry, where the H-shaped member is inserted between the C-shaped members, converting longitudinal movement into transverse fastening forces, and the cement slurry provides additional strength and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If bolted connection is used to connect prefabricated components, then the components can be assembled together, but the connection strength is insufficient and the construction efficiency is low
Solution Approach 1:
The connection assembly is divided into distinct functional components: C-shaped groove members integrated into the prefabricated components, and H-shaped connection members serving as independent connecting elements. This segmentation allows each part to be optimized for its specific function while maintaining overall connection strength and simplifying the assembly process.
Solution Approach 2:
The C-shaped groove members are pre-integrated into the prefabricated components during manufacturing, and the H-shaped connection members are designed with predetermined geometric features. This preliminary preparation eliminates the need for complex on-site assembly operations, significantly improving construction efficiency while ensuring connection strength.
2Strength
If multiple bolts are used to achieve high-strength connection, then the connection strength can be improved, but the operation becomes cumbersome and construction efficiency decreases
Solution Approach 1:
Multiple fastening functions that would traditionally require multiple bolts are merged into a single H-shaped connection member. This integration maintains the high-strength connection capability while dramatically simplifying the operation, as workers only need to install one component rather than multiple bolts.
Solution Approach 2:
The H-shaped connection member serves multiple functions simultaneously: it provides structural connection, enables fastening through its geometric design with the C-shaped grooves, and facilitates alignment. This multi-functionality eliminates the need for separate fastening operations, reducing operational complexity while maintaining connection strength.
3Device complexity
If traditional bolted connection is used, then the assembly process is simple in terms of components, but the connection strength is insufficient under high shearing force and bending moment
Solution Approach 1:
The connection assembly combines different geometric forms (C-shaped and H-shaped members) that work together to create a composite structural system. This composite design leverages the complementary strengths of each shape to resist both shearing forces and bending moments, achieving high connection strength without excessive structural complexity.
Solution Approach 2:
The connection design transitions from traditional linear bolt arrangements to a three-dimensional geometric interlocking system. The C-shaped and H-shaped members create spatial engagement that distributes loads across multiple dimensions, significantly enhancing connection strength under complex loading conditions while maintaining reasonable structural complexity.
