Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple power sources are used to supply the electromechanical lock, then the reliability of power supply is improved, but the complexity of power management increases
Solution Approach 1:
The patent combines multiple power sources (generator, NFC wireless power, and battery) into a unified power management system. The DC-DC converter integrates inputs from different power sources and merges them into a single charging circuit that charges a common energy storage capacitor, thereby improving power supply reliability while managing complexity through integration.
Solution Approach 2:
The charging system is designed with multi-functionality to handle different power sources universally. The DC-DC converter can accept power from the generator, NFC wireless transmission, or battery, and adaptively manages the charging process regardless of the power source type, making the system versatile and reducing management complexity.
2Adaptability or versatility
If kinetic energy from user interaction is converted to electrical energy, then the need for external power sources is reduced, but the efficiency of energy conversion varies with user input
Solution Approach 1:
The system dynamically adapts to varying user input levels by using a DC-DC converter that can adjust its operating parameters. When the user interacts with the knob or handle, the generator produces variable electrical energy, and the DC-DC converter dynamically regulates the charging process to maximize energy capture and minimize losses, thereby maintaining efficiency across different input levels.
Solution Approach 2:
The DC-DC converter changes its operating parameters (such as duty cycle and switching frequency) based on the amount of electrical energy generated by the user's kinetic input. This parameter adjustment optimizes the energy conversion efficiency across different user interaction intensities, reducing energy losses while maintaining adaptability to various power source conditions.
3Ease of manufacture
If wireless power transfer from communication devices is used, then the installation complexity is reduced, but the power transfer efficiency decreases
Solution Approach 1:
The patent merges wireless NFC power transfer with other power sources (generator and battery) into a hybrid power system. The NFC module provides convenient wireless charging without installation complexity, while the DC-DC converter and energy storage system compensate for the lower efficiency of wireless power transfer by integrating multiple power sources to ensure reliable and efficient overall power supply.
