Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple sensors and electronic components are integrated into medical devices using traditional wiring methods, then the device functionality and sensor capacity are improved, but the number of external connections increases which compromises flexibility and increases complexity
Solution Approach 1:
The patent merges multiple separate electrical connections into a single integrated Flexible Printed Circuit Board (FPC) that carries multiple signals simultaneously. The FPC combines power supply lines, ground connections, and sensor signal lines into one unified structure, reducing the number of external connections while maintaining all necessary electrical connections for multiple sensors and components.
Solution Approach 2:
The FPC serves multiple functions simultaneously: it provides structural support, electrical connectivity, signal transmission, and power distribution all through a single component. This multi-functional approach eliminates the need for separate wiring harnesses and connection elements, thereby reducing overall device complexity while supporting multiple sensors.
2Adaptability or versatility
If multiple sensors and electronic components are integrated into medical devices using traditional wiring methods, then the device functionality is improved, but flexibility is compromised
Solution Approach 1:
The patent employs a Flexible Printed Circuit Board (FPC) made from thin, flexible materials that can bend and deform with the medical device. This flexible substrate maintains the flexibility needed for endoscopic and minimally invasive procedures while providing robust electrical connections for multiple sensors and components, solving the contradiction between functionality and flexibility.
3Reliability
If numerous electrical conductors are used to power and connect components, then the electrical connectivity is improved, but the device becomes more complex and harder to manufacture
Solution Approach 1:
The patent consolidates multiple electrical conductors and connection paths into a single FPC structure that is manufactured as one integrated component. This merging approach maintains reliable electrical connectivity for power, ground, and signal lines while dramatically simplifying the manufacturing process compared to assembling multiple separate wires and connectors.
