Engineering Contradiction Analysis
1Reliability
If the circuit board is designed to accommodate a specific source voltage, then the electrical characteristics are optimized for that voltage, but the cost increases when different voltages are required due to complete redesign
Solution Approach 1:
The circuit board is designed with a wiring pattern that can universally accommodate multiple source voltages (200V and 400V). By setting the spacing between adjacent printed wires to meet the insulation distance requirement for the higher voltage (400V), the same circuit board can be used for both 200V and 400V applications, eliminating the need for complete redesign when voltage requirements change.
Solution Approach 2:
The invention changes the design parameter of printed wire spacing to satisfy the insulation distance requirement for the highest expected voltage (400V). This parameter adjustment allows the circuit board to safely operate at both 200V and 400V without requiring different wiring patterns, thereby reducing manufacturing costs while maintaining electrical safety and optimization.
2Reliability
If the entire circuit board is redesigned to accommodate different source voltages, then the electrical characteristics are optimized, but the load and cost for redesign increase
Solution Approach 1:
The circuit board wiring pattern is designed to be universal across different voltage specifications. By anticipating the need for higher voltage (400V) and designing the spacing accordingly, the same board serves both 200V and 400V applications, eliminating the need for time-consuming complete redesigns when voltage requirements vary.
Solution Approach 2:
The design proactively sets the printed wire spacing to meet the insulation distance requirement for the higher voltage (400V) in advance. This preliminary action ensures that when 400V operation is needed, no redesign is required, as the board was already prepared to accommodate this voltage level.
3Area of stationary object
If the spacing between printed wires is reduced for lower voltage, then the circuit board size is minimized, but the insulation distance is insufficient for higher voltage operation
Solution Approach 1:
The circuit board is designed with a wiring pattern that universally satisfies the insulation distance requirement for both 200V and 400V operations. By setting the spacing between adjacent printed wires to meet the 400V requirement, the same board area design can be used for both voltage levels, eliminating the need for separate optimized designs.
Solution Approach 2:
The design parameter of printed wire spacing is set to satisfy the insulation distance requirement for the higher voltage (400V). This parameter choice, while larger than what would be strictly necessary for 200V alone, enables the board to safely operate at both voltage levels without requiring area optimization for each specific voltage.

AI summary
A circuit board accommodates a plurality of different source voltages. On the circuit board, a printed wire which constitutes a circuit is formed, a first circuit component used for a board which meets specifications for a first voltage or a second circuit component used for a board which meets specifications for a second voltage higher than the first voltage, is mounted, and spacing between adjacent printed wires is equal to or larger than a distance which secures an insulation distance when the second voltage is input.
