Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the output power of the power supply device is increased to drive more internal devices, then the power supply capability is improved, but the volume of electronic components (such as capacitors) increases proportionally with the rated working voltage, occupying more space on the circuit board
Solution Approach 1:
The patent applies nesting by placing the converting module inside the driving module's bounding box. The converting module, which includes capacitors and other components, is positioned within the spatial envelope defined by the driving module, thereby utilizing the available space more efficiently and reducing the overall device volume while maintaining high power output capability
2Power
If larger volume electronic components are placed on the circuit board to handle higher power, then the power supply capability is improved, but the space occupancy on the circuit board increases, preventing miniaturization
Solution Approach 1:
The patent transitions from a two-dimensional layout on the circuit board to a three-dimensional arrangement by stacking modules vertically. The driving module and converting module are arranged in layers with the converting module positioned below the driving module, utilizing the vertical dimension to accommodate larger components without increasing the horizontal footprint on the circuit board
3Power
If high power systems are designed to handle heavy loads, then the power supply capability is improved, but the system operates inefficiently under light loads
Solution Approach 1:
The patent implements dynamic operation by enabling the power supply device to adapt its output according to actual load requirements. The control system adjusts the operating parameters of the driving module and converting module based on detected load conditions, allowing the high-power system to operate efficiently under both light and heavy load conditions by dynamically optimizing its performance characteristics
