Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the power supply unit uses the main circuit board as the power output path, then the structure is simple and easy to manufacture, but the output impedance is high which reduces efficiency
Solution Approach 1:
The power output path is segmented into two separate paths: a signal path through the main circuit board and a power path through the output connection electrode. This segmentation allows the power transmission to bypass the high-impedance circuit board traces, reducing output impedance and improving efficiency while maintaining structural simplicity through modular design.
Solution Approach 2:
The output connection electrode serves as an intermediary component that directly connects the transformer to the power output panel. This intermediary provides a low-impedance power transmission path, eliminating the need for power to traverse the main circuit board, thereby reducing output impedance and enhancing power supply efficiency.
2Productivity
If the power output path passes through the main circuit board, then the circuit board serves multiple functions, but the output impedance increases reducing power supply efficiency
Solution Approach 1:
The patent segments the electrical connection into distinct signal and power pathways. The output connection electrode creates a dedicated power transmission channel that is electrically isolated from the main circuit board's signal traces, thereby eliminating the harmful high output impedance effect while preserving the circuit board's multifunctional role.
Solution Approach 2:
The power transmission function is extracted from the main circuit board by introducing the output connection electrode. This extraction removes the detrimental effect of the circuit board's trace impedance on power delivery, allowing the circuit board to focus on signal processing while the dedicated electrode handles power transmission with minimal impedance.
