Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If voltage-regulated power supplies are designed for specific voltage ranges to ensure efficiency, then efficiency is improved, but the number of power supply types increases and management becomes difficult
Solution Approach 1:
The patent implements dynamic voltage range adjustment by making the resonant frequency of the tank circuit可调 (adjustable). The control module dynamically changes the resonant frequency based on the input voltage magnitude, allowing the power supply to maintain high efficiency across a wide voltage range (90-264V AC) rather than being fixed to a specific range. This dynamic adaptation eliminates the need for multiple fixed-range power supply models.
Solution Approach 2:
The patent changes the resonant frequency parameter of the tank circuit to adapt to different input voltage conditions. By adjusting the resonant frequency based on the detected input voltage magnitude, the power supply optimizes its operating parameters in real-time, maintaining high efficiency across varying voltage conditions without requiring different hardware models.
2Adaptability or versatility
If power supplies are designed to support multiple voltage ranges, then adaptability is improved, but efficiency deteriorates due to operating outside optimal ranges
Solution Approach 1:
The patent incorporates a feedback mechanism where the control module detects the magnitude of the input voltage and uses this information to adjust the resonant frequency of the tank circuit. This closed-loop feedback ensures that the power supply always operates at or near its optimal resonant frequency regardless of input voltage variations, maintaining high efficiency while supporting wide voltage adaptation.
Solution Approach 2:
The resonant frequency is made dynamically adjustable rather than fixed. The control module continuously monitors input voltage conditions and adjusts the tank circuit's resonant frequency in real-time, enabling the power supply to maintain optimal efficiency across different voltage ranges (90-264V AC) without sacrificing adaptability.
3Adaptability or versatility
If different types of power supplies are used for different electronic devices, then device compatibility is improved, but management complexity and costs increase
Solution Approach 1:
The patent designs a universal power supply that can serve multiple electronic devices with different voltage requirements through a single model. By implementing adjustable resonant frequency control and wide input voltage acceptance (90-264V AC), the power supply can adapt to various device requirements without needing different hardware models, thereby simplifying inventory management and reducing costs.
Solution Approach 2:
The patent segments the operating voltage range into different levels (first voltage range, second voltage range, third voltage range) and uses the switch switching unit to select appropriate connection configurations for each segment. This segmentation allows the single power supply to efficiently handle different voltage requirements of various devices while maintaining optimal performance in each segment.
4Device complexity
If the resonant frequency of the tank circuit is fixed, then circuit simplicity is improved, but voltage adaptation capability deteriorates
Solution Approach 1:
The patent transforms the fixed resonant frequency into a dynamically adjustable parameter. The control module modifies the resonant frequency based on the detected input voltage magnitude, allowing the tank circuit to adapt to different voltage conditions. This dynamic adjustment is achieved through controlled switching of capacitor connections, maintaining relative circuit simplicity while significantly improving voltage adaptation capability.
