Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing anti-shoplifting devices are used, then product protection is provided, but removal by authorized personnel is cumbersome and complicated
Solution Approach 1:
The patent replaces complex mechanical fastening systems with a magnetic locking mechanism. The magnetic field enables authorized personnel to easily unlock and remove the device by simply bringing a magnet close, eliminating the need for special screwdrivers or complex mechanical tools while maintaining security.
Solution Approach 2:
The patent changes the state of the locking mechanism from mechanically locked to magnetically locked. By using magnetic fields instead of mechanical fasteners, the device transitions between locked and unlocked states through parameter changes in the magnetic field strength, enabling easy removal by authorized personnel with simple magnetic tools.
2Reliability
If existing anti-shoplifting devices are used, then some security is provided, but unauthorized opening and product removal is not prevented
Solution Approach 1:
The patent introduces a magnetic field as an intermediary between the locking mechanism and the user. This magnetic intermediary enables authorized access through simple magnetic tools while simultaneously preventing unauthorized access, as the magnetic locking mechanism requires specific magnetic field patterns to unlock, providing both security and ease of operation for authorized personnel.
3Reliability
If existing anti-shoplifting devices are used, then security function is provided, but manufacturing cost and component number are high
Solution Approach 1:
The patent extracts the essential security function from complex mechanical systems and isolates it into a simple magnetic locking mechanism. By taking out only the core locking function and implementing it through a magnetic field with minimal components, the device achieves high security reliability while dramatically reducing manufacturing complexity and cost.
Solution Approach 2:
The patent employs a simple magnetic locking mechanism that can be manufactured at low cost with minimal components. The magnetic system replaces expensive mechanical assemblies, allowing for economical production while maintaining effective security functionality throughout the device's service life.
