Solution Overview
Problem
Conventional anti-theft devices, such as password setting, remote control, and magnetic card types, are vulnerable to theft as they can be forgotten, easily cracked, or have fixed and simple designs, lacking effective deterrent and safety measures.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional anti-theft devices (password, remote control, magnetic card) are used, then the device can be operated and unlocked, but they are easily cracked or forgotten by thieves
Solution Approach 1:
The patent changes the authentication parameter from fixed values (passwords, remote control codes, magnetic card patterns) to variable magnetic field strengths. Multiple magnetic sensors detect different magnetic induction strengths generated by magnetic elements in the unlock piece, creating a more complex and secure authentication mechanism that is difficult to crack or forget.
2Ease of operation
If magnetic card type alarms are used, then the alarm can be set and released, but the design is fixed and simple making it easy to crack
Solution Approach 1:
The patent segments the authentication process into multiple independent magnetic sensors, each detecting specific magnetic induction strengths. This segmentation creates a multi-layered authentication system where each sensor contributes to the overall verification, making the system more reliable while maintaining ease of operation through the same unlock piece interface.
Solution Approach 2:
The patent employs a composite authentication approach combining multiple magnetic elements with different magnetic induction strengths in the unlock piece, corresponding to multiple magnetic sensors. This composite structure creates a sophisticated magnetic fingerprint that is easy to operate with but difficult to replicate, resolving the contradiction between operational simplicity and anti-theft effectiveness.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances security by ensuring only correctly matched unlock pieces can disarm the device, preventing unauthorized access and increasing safety through accurate magnetic force induction verification.
Implementation Method 1
the magnetic sensor is a magnetic induction coil having an action of inducting a magnetic strength, thereby inducting the magnetic strengths of the unlock piece for the interpretation of the control circuit

AI summary
A magnetic anti-theft device, includes: a control circuit, in connection with a plurality of magnetic sensors and a control unit; the plurality of magnetic sensors, allowing different magnetic induction strengths to be preset; and an unlock piece, configured with a plurality of magnetic elements corresponding to the magnetic induction strengths of the plurality of magnetic sensors, whereby, when the correct unlock piece is placed on the magnetic sensors, the plurality of magnetic sensors will induct correct magnetic forces, the control unit is driven to release a monitoring state after interpretation of the control circuit; if the induction is incorrect, the control unit is driven to form a warning action after the interpretation of the control circuit so as to achieve an anti-theft effect and increase safety effectively probably because the magnetic force of the magnetic element of the unlock piece is too small or too large.
