Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for joining reinforcing bars, particularly with high-stiffness bars, face challenges such as difficulty in aligning screw threads, texture changes due to processing, and reduced ductility, leading to poor joining quality and increased tool wear, especially with the need for specialized welding methods to prevent deformation.
Innovation Solution
A socket-fastening-type reinforcing bar connector using binding end members with a fastening socket that allows integrated coupling without aligning centers or screw threads, enabling joining of reinforcing bars with different sizes and shapes, and accommodating construction errors through adjustable length configurations and middle binding members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw coupling method using couplers is used to join reinforcing bars, then mechanical joining is achieved, but precise alignment of screw threads is difficult and fastening work becomes strenuous
Solution Approach 1:
The patent introduces a connector as an intermediary component that replaces direct screw coupling between reinforcing bars. The connector includes a body with a through hole and a binding member that wraps around both reinforcing bars, providing a mediator that eliminates the need for precise screw thread alignment while achieving mechanical joining.
Solution Approach 2:
The joining system is segmented into separate functional components: the connector body that provides the joining mechanism, the binding member that secures the reinforcing bars, and the reinforcing bars themselves. This segmentation allows each component to be optimized independently, with the binding member handling alignment tolerance and the connector body providing the mechanical connection.
2Strength
If male screw processing is performed at end portions of reinforcing bars to join them, then mechanical joining is enabled, but texture changes occur and ductility is reduced
Solution Approach 1:
The patent extracts the screw processing operation from the reinforcing bar end portions and relocates it to the connector body. The binding member wraps around the reinforcing bars without requiring any processing of the bar ends, thereby preserving the original texture and ductility of the reinforcing bars while still enabling mechanical joining through the connector.
Solution Approach 2:
The connector acts as an intermediary that provides the screw processing interface separately from the reinforcing bars. The male screw portions are formed on the binding member or connector body rather than on the reinforcing bars themselves, allowing the bars to maintain their original material properties without processing-induced texture changes or ductility loss.
3Stability of the object's composition
If specialized welding methods are used to join high-stiffness reinforcing bars, then deformation is prevented, but device complexity and tool requirements increase
Solution Approach 1:
The patent replaces the welding process (thermal/mechanical system) with a mechanical binding system. The binding member wraps around and secures the reinforcing bars through friction and mechanical interlocking, eliminating the need for specialized welding equipment while effectively preventing deformation of high-stiffness bars through distributed mechanical constraint.
4Ease of operation
If couplers with wider female screw threads are used to improve processability, then screw coupling becomes easier, but gaps between fastened screw threads increase and connection becomes less sturdy
Solution Approach 1:
The binding member serves as an intermediary that distributes the fastening force around the reinforcing bars rather than concentrating it at a single screw interface. This eliminates the trade-off between thread width and connection sturdiness by providing continuous circumferential contact and load distribution through the wrapped binding member.
