Innovation Solution
A power supply circuit comprising a transducer to convert non-electrical energy into electrical energy, an energy storage assembly to store this energy, and a power supply assembly that monitors output voltage to ensure efficient charging and power supply to the power consumption module only when necessary, using multiple energy storage modules and control mechanisms to optimize charging efficiency and rapid power-on.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the energy storage assembly continuously supplies power to the power consumption module, then the module can operate continuously, but the charging efficiency before power-on is reduced and start-up speed is slowed
Solution Approach 1:
The patent applies preliminary action by establishing a pre-power supply phase where the energy storage assembly charges to a specified voltage threshold before actually powering the consumption module. During this preliminary charging phase, the power supply assembly monitors voltage and prevents power delivery until the threshold is reached, optimizing charging efficiency while ensuring sufficient energy is stored for subsequent operation.
2Productivity
If the power supply assembly monitors voltage to prevent premature power supply, then charging efficiency is improved, but the system complexity increases
Solution Approach 1:
The patent implements feedback control where the power supply assembly continuously monitors the output voltage of the energy storage assembly and adjusts power supply accordingly. The monitoring mechanism compares the actual voltage against a predetermined specified voltage interval, enabling automatic control decisions that improve charging efficiency without requiring complex external control systems.
3Speed
If the energy storage assembly waits to supply power until voltage threshold is reached, then start-up speed is improved, but the module remains non-operational during the charging phase
Solution Approach 1:
The system applies self-service by automatically managing the power supply timing without requiring external intervention. The power supply assembly autonomously monitors voltage levels and determines when to initiate power delivery to the consumption module, eliminating the need for manual control while achieving rapid start-up once the voltage threshold is satisfied.
