Solution Overview

Problem

Existing reinforcing bar binding robots face inefficiencies due to delays in determining the position of intersecting portions, which hinder the efficient performance of binding work, especially in automated systems aiming to improve construction efficiency.

Innovation Solution

A reinforcing bar binding robot equipped with a sensor unit that detects reinforcing bars and calculates their positions based on pixel values from a two-dimensional image, allowing for precise and efficient binding at intersecting points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If sensor detection results are processed using traditional calculation methods, then the position of intersecting portions can be determined, but the calculation time is too long which reduces binding work efficiency

Engineering Contradiction:
Improvebinding work efficiencyVSAvoidcalculation time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent replaces traditional mechanical calculation methods with a vision-based detection system using cameras and image processing algorithms. The sensor unit captures images of reinforcing bars, and the control unit processes these images to directly determine positions and intersections, eliminating complex mathematical calculations and significantly reducing computation time while improving binding work efficiency

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent creates a visual copy (image) of the reinforcing bar structure through the sensor unit's camera. This optical copy allows the control unit to analyze positions and intersections by processing image data rather than performing extensive calculations on raw sensor data, thereby reducing calculation time and improving overall productivity

Inventive Principle:
Principle #26Copying
