Solution Overview
Problem
Conventional metal detectors are costly and require significant manpower, and they do not efficiently detect metal foreign objects in shoe manufacturing processes, leading to potential defects and safety hazards.
Innovation Solution
A detecting machine comprising a base unit with a transporting module and an overhead arch, a magnetic sensor, a tag reader, and a processor-connected display unit that moves objects past the arch, detects magnetic signals, reads tags, and displays results to indicate the presence of metal foreign objects, reducing manual inspection and improving detection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional metal detectors are used to detect metal foreign objects, then detection capability is provided, but cost and manpower requirements increase
Solution Approach 1:
The patent replaces conventional metal detectors with a magnetic sensor-based detection system. The magnetic sensor detects metal foreign objects by sensing magnetic field changes caused by the movement of metallic objects through the overhead arch, eliminating the need for expensive and complex conventional metal detector equipment and reducing operational complexity
Solution Approach 2:
The patent introduces an overhead arch as an intermediary structure that carries the magnetic sensor. This arch serves as a mediator between the conveyor belt system and the detection function, allowing magnetic field-based detection without requiring direct contact or complex integration with the product handling system
2Ease of operation
If manual inspection is used to identify defective items, then flexibility is maintained, but productivity decreases
Solution Approach 1:
The system enables self-service detection where the magnetic sensor automatically detects metal foreign objects and the processor automatically determines detection results without requiring manual inspection. The system serves itself by providing automated detection and classification functions that were previously requiring human operators
Solution Approach 2:
The patent implements feedback through the display unit that provides real-time visual feedback about detection results. The processor analyzes magnetic sensor signals and provides immediate feedback through the display, enabling operators to quickly identify and respond to detected metal foreign objects without manual inspection delays
