One-Touch Coupling Clip for Reinforcing Bars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coupling methods for reinforcing bars in ferroconcrete structures are laborious, prone to imbalance, and require complex structures with high manufacturing costs, often resulting in separation of bars due to the use of elastic wings that cannot withstand the weight of the bars.
Innovation Solution
A one-touch coupling clip made of synthetic resin with inclined side members and semicircle-shaped coupling grooves for both upper and lower reinforcing bars, featuring a stopper to prevent separation and an optional RFID chip for identification, allowing for a simple, stable, and balanced coupling without the need for elastic wings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional reinforcing bar supporter with an elastic wing is used to prevent separation, then the reinforcing bar can be prevented from separating, but the structure becomes complicated and manufacturing costs increase
Solution Approach 1:
The patent removes the elastic wing component from the reinforcing bar supporter, extracting the problematic element that caused structural complexity and manufacturing difficulties while maintaining the core function of preventing bar separation through the remaining simplified structure
Solution Approach 2:
The supporter is divided into distinct functional segments: a main body structure for support and positioning, and a separate stopper component for preventing separation. This segmentation allows each part to perform its specific function efficiently without requiring a complex integrated design
2Ease of operation
If a conventional reinforcing bar supporter is used, then the reinforcing bar can be supported, but the supporter becomes inclined due to imbalance and the bar may separate
Solution Approach 1:
The patent employs asymmetric design in the positioning of the stopper relative to the main body of the supporter. The stopper is positioned to provide counterbalancing force that prevents inclination, creating a stable equilibrium that maintains the supporter in a vertical, balanced position during operation
3Reliability
If a conventional reinforcing bar supporter with elastic wing is used, then separation can be prevented, but the elastic wing cannot endure the weight of the reinforcing bar and may separate
Solution Approach 1:
The patent replaces the elastic wing with a stopper design that does not rely on elastic deformation to function. The stopper is designed as a rigid or semi-rigid component that provides mechanical blocking action, eliminating the need for materials with high elastic recovery properties that would be required to support reinforcing bar weights
4Reliability
If coupling wire and reinforcing bar coupler are used to bind intersecting reinforcing bars, then the bars can be coupled, but the work requires lots of time and is laborious
Solution Approach 1:
The patent combines the functions of support, positioning, and coupling prevention into a single integrated supporter component. This merging eliminates the need for separate coupling wires and couplers, allowing workers to install the supporter as a single unit that performs multiple functions simultaneously, thereby dramatically improving installation efficiency

AI summary
A coupling clip for coupling an upper reinforcing bar and a lower reinforcing bar includes a pair of side members spaced apart from each other and provided to be inclined with respect to the upper reinforcing bar, an upper member having a semicircle-shaped upper reinforcing bar coupling groove, and lower members being formed to vertically protrude from the lower end of each side member and having semicircle-shaped lower reinforcing bar coupling grooves. The side members and the lower members are formed to be inclined, such that a line connecting the upper part of the upper reinforcing bar coupling groove and the lower end of the lower reinforcing bar coupling groove has a vertical distance, and is perpendicular to the longitudinal direction of the upper reinforcing bar when the one-touch coupling clip is combined to the upper reinforcing bar and the lower reinforcing bar intersecting each other orthogonally.
