Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lock mechanism is used to secure the cable to the sensor, then the security against theft is improved, but the complexity of the security device increases
Solution Approach 1:
The patent replaces complex mechanical lock mechanisms with a magnetic locking system. The sensor contains a magnet that magnetically engages with a ferromagnetic material in the cable or connector, providing secure attachment without complex mechanical components. This substitution maintains reliability while reducing device complexity.
Solution Approach 2:
The patent changes the locking mechanism from mechanical interlocking to magnetic field interaction. By utilizing magnetic field strength as the securing parameter instead of mechanical engagement, the system achieves reliable theft prevention with simpler device architecture.
2Reliability
If the cable is permanently locked to the sensor, then theft prevention is improved, but the ease of operation for legitimate removal deteriorates
Solution Approach 1:
The patent implements a dynamic locking system where the magnetic engagement can be easily overridden. A release mechanism allows the cable connector to be pulled away from the sensor, overcoming the magnetic force when needed. This provides permanent security during normal operation while enabling easy removal for legitimate purposes such as customer interaction or cable replacement.
Solution Approach 2:
The system incorporates a preliminary release mechanism that counteracts the magnetic locking force. When the release button or mechanism is activated, it pre-positioned to overcome the magnetic attraction, allowing smooth and easy cable removal when legitimate access is required.
3Ease of operation
If a wireless control system is added to lock and unlock the mechanism, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a wireless communication module as an intermediary between the user and the lock mechanism. A remote device or key fob communicates wirelessly with the sensor, transmitting unlock commands without requiring direct physical interaction with the sensor. This improves ease of operation while keeping the added complexity minimal and modular.
4Reliability
If the lock mechanism is made more secure, then theft prevention is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent replaces complex mechanical security mechanisms with a magnetic locking system that is simpler to manufacture. The magnet and ferromagnetic materials can be easily integrated into the sensor and cable components using standard manufacturing processes, avoiding the need for precision mechanical assembly of complex locking mechanisms.
