Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a circuit board is designed as a single integrated structure, then manufacturing and assembly are simplified, but flexibility and interchangeability are reduced
Solution Approach 1:
The circuit board is divided into two separate portions: a pad board portion containing pads and conductive structures, and a circuit module portion containing the circuit components. These portions can be manufactured separately and then assembled together through surface mounting, enabling both manufacturing efficiency and flexibility. The separation allows the circuit module to be interchangeable while maintaining ease of manufacture for each component.
2Manufacturing precision
If a circuit board is designed for fixed configuration, then manufacturing precision requirements are reduced, but adaptability to different configurations is limited
Solution Approach 1:
The pad board portion is designed with universal pads and conductive structures that can accommodate multiple different circuit module configurations. The standardized interface allows the same pad board to work with various circuit modules, providing configuration flexibility without requiring high precision for each specific configuration. The universal design enables adaptability while maintaining reasonable manufacturing precision standards.

AI summary
A circuit board may include a pad board portion comprising one or more pads and a circuit module portion within the pad board portion and comprising a circuit electrically coupled to the one or more pads. The pad board portion and circuit module portion may be arranged such that they can be separated from each other in a manner such that the pad board portion is configured to electrically couple to a circuit module surface mounted to the pad board portion via the one or more pads and the circuit module portion is configured to electrically couple to a pad board via pads of the pad board.
