Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current food cutting and processing machines lack adequate safety mechanisms to ensure that cutting or grating operations are only performed when the accessory container is properly positioned, potentially leading to accidents and unsafe usage.
Innovation Solution
A magnetic safety device that utilizes a magnetized element and a magnet sensor to detect the correct positioning of the thrusting element and accessory container, allowing the machine to operate safely by ensuring the container is closed and the product is in contact with cutting or grating elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical safety switches are used to detect container positioning, then the safety mechanism is reliable, but the device complexity and risk of mechanical failure increase
Solution Approach 1:
The patent replaces traditional mechanical safety switches with a magnetic detection system. A magnet is attached to the thrusting element, and a magnetic sensor (such as a Hall effect sensor or reed switch) is positioned in the motor block to detect the magnet's position. This substitution eliminates mechanical contact and moving parts in the safety detection mechanism, thereby reducing device complexity while maintaining or improving reliability through non-contact sensing.
Solution Approach 2:
The patent introduces a magnet as an intermediary element between the thrusting element and the magnetic sensor. This magnet serves as a non-contact signal carrier that communicates the position state of the thrusting element to the control system. By using this magnetic intermediary, the system achieves reliable position detection without direct mechanical coupling, thus simplifying the overall safety device structure.
2Difficulty of detecting and measuring
If mechanical safety switches with physical contact are used, then the detection is straightforward, but the risk of mechanical failure and wear increases
Solution Approach 1:
The patent replaces mechanical contact-based position detection with a magnetic field-based detection system. The magnet attached to the thrusting element generates a magnetic field that is detected by the magnetic sensor in the motor block. This non-contact detection method eliminates mechanical wear and contact failure, significantly improving the reliability of the safety mechanism while maintaining straightforward position detection capability.
Solution Approach 2:
The magnet serves as a non-contact intermediary that transfers position information from the thrusting element to the sensor without physical contact. This intermediary approach allows the system to detect the position state (whether the container is properly closed) through magnetic field interaction rather than mechanical contact, thereby eliminating wear and contact-related failures.
3Ease of manufacture
If the safety device uses simple mechanical linkages, then the ease of manufacture is high, but the precision of position detection is insufficient
Solution Approach 1:
The patent replaces simple mechanical linkages with a magnetic detection system that offers superior position detection precision. The magnetic sensor can detect the presence and position of the magnet with high accuracy, providing precise feedback on whether the thrusting element is in the correct position. This electronic/magnetic detection method maintains ease of manufacture while significantly improving measurement precision compared to mechanical linkages.
