Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manual insertion of reinforcement bars into preassembled grid-like structures in the building sector is time-consuming and labor-intensive, slowing down the production cycle and increasing production costs.
Innovation Solution
An automated assembly system controlled by a programmed handling device that selects and inserts straight or bent reinforcement bars into preassembled grid-like structures using rollers, pusher clamps, and U-shaped guides, with a movable bending device for creating S-shaped bends, allowing for precise positioning and electro-welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual insertion of reinforcement bars is used, then flexibility in handling various bar configurations is maintained, but production time increases and productivity decreases
Solution Approach 1:
The system uses automated handling devices with rollers and pusher clamps that automatically select, position, and insert reinforcement bars without human intervention. The magazine automatically feeds bars to the handling device, which then positions them precisely within the grid-like structure using programmable movements.
Solution Approach 2:
The patent replaces manual mechanical operations with an automated programmable handling device that uses rollers for support and pusher clamps for positioning. The system substitutes human labor with automated mechanical systems controlled by programmed sequences, significantly increasing production speed while maintaining precision.
2Productivity
If automated handling devices are introduced, then production efficiency increases, but device complexity increases
Solution Approach 1:
The handling device is designed as a multi-functional system that can handle various types of reinforcement bars (different diameters, lengths, and configurations) using the same basic mechanism of rollers and pusher clamps. The programmable nature of the device allows it to adapt to different bar types without requiring separate specialized equipment for each case.
Solution Approach 2:
The system employs movable and adjustable components including rollers that can reposition along the bar length and pusher clamps that can adjust their positioning. The entire handling device is programmably controllable, allowing dynamic adaptation to different bar configurations and insertion requirements, thereby managing complexity through flexibility rather than fixed specialized mechanisms.
3Adaptability or versatility
If S-shaped bends are added to reinforcement bars, then stacking capability during installation is improved, but manufacturing complexity increases
Solution Approach 1:
The S-shaped bends are pre-formed on the reinforcement bars before they are inserted into the grid-like structure. The automated bending device creates the double S-shaped bends in advance, allowing the bars to be properly stacked during installation. This preliminary action ensures that the bending function is integrated into the manufacturing process without complicating the insertion operation.
Solution Approach 2:
The patent combines the bending function with the reinforcement bar manufacturing process by integrating a bending device into the automated handling system. The bending operation is merged with the bar preparation and insertion sequence, creating a unified automated process that produces S-shaped bars on-demand without requiring separate manual bending operations.

AI summary
An automatic assembly or machine for bending and inserting reinforcement bars (2.1) in preformed metallic reinforcement cages (3). The assembly or machine provides for a movable magazine (6) of straight metal bars of various diameters and/or lengths, which is arranged automatically below at least one electromagnetic lifting assembly (4), which positions the chosen bar within appropriately provided horizontal sliding clamps (5). A bar control advancement device pushes the bar toward the bending device (8), which produces an "bottle-neck"-shaped (S-shaped) bend (2.1); then an automatic movable clamp (9) picks up the trailing edge of the bar and positions it. The bar (2.1) is positioned exactly within the cage by virtue of U-shaped sliding guides (10) and is subsequently electro-welded (12) to the grid-like structure.
