Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a voltage increasing circuit (boost converter) is added to the electronic lock, then the driving capability for high-consumption components (motor, buzzer) is improved, but the circuit complexity and power loss increase
Solution Approach 1:
The patent combines the voltage increasing circuit functionality into the existing power supply module by integrating the boost converter with the switching regulator. The switching regulator's inductor and control circuitry are utilized to provide both voltage regulation and voltage boosting functions, eliminating the need for separate boost converter components and reducing overall circuit complexity while maintaining enhanced driving capability for motor and buzzer operations
2Power
If a voltage increasing circuit (boost converter) is added to the electronic lock, then the driving capability for high-consumption components (motor, buzzer) is improved, but the power loss increases
Solution Approach 1:
The patent merges the boost converter functionality with the switching regulator to create a unified power management system. By using the same inductor and control circuitry for both voltage regulation and voltage boosting, the system reduces redundant power losses that would occur with separate circuits. The integrated design allows efficient energy transfer and minimizes losses during the voltage conversion process while still providing sufficient driving capability for high-consumption components
3Power
If separate voltage increasing circuit and power supply circuit are used, then the voltage can be increased, but the number of components increases and space is consumed
Solution Approach 1:
The patent integrates the voltage increasing circuit and power supply circuit into a single unified power supply module. The switching regulator is designed to perform both voltage regulation and voltage boosting functions using shared components such as the inductor, control circuitry, and power switch. This integration reduces the total number of components required while maintaining the capability to increase voltage for motor and buzzer operations, thereby saving PCB space and reducing assembly complexity
