Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensor devices are physically connected to power source and display device, then power supply and data transmission are ensured, but mobility is limited and wire management becomes challenging
Solution Approach 1:
The patent extracts the power source and wireless transmission capabilities from external equipment and integrates them directly into the sensor device itself. This allows the sensor to operate independently without physical connections to external power sources or display devices, thereby eliminating wire management challenges while maintaining reliable power supply and data transmission.
Solution Approach 2:
The patent replaces the mechanical connection system (wires and connectors) with a wireless transmission system. The sensor device incorporates wireless communication capabilities to transmit data and power information without physical connections, eliminating the need for wire management while ensuring reliable operation.
2Reliability
If electrical connectors are uncovered or cleaned for connection, then proper electrical contact is achieved, but sterile field may be breached
Solution Approach 1:
The patent removes the need for external electrical connectors entirely by integrating power source and wireless transmission capabilities directly into the sensor device. This eliminates the requirement to uncover or clean connectors, thereby preventing any potential breach of the sterile field while maintaining reliable power supply and data transmission.
Solution Approach 2:
The patent replaces the mechanical connector system with an integrated wireless transmission system. This substitution eliminates the need for physical electrical connections that would require connector manipulation, thereby maintaining sterile field integrity while ensuring reliable operational functionality.
3Reliability
If sensor devices require physical connections to display device, then data transmission is ensured, but procedural complexity increases
Solution Approach 1:
The patent extracts wireless transmission capabilities from external display equipment and integrates them directly into the sensor device. This allows the sensor to transmit data wirelessly without requiring physical connections to external display devices, thereby reducing procedural complexity while maintaining reliable data transmission.
Solution Approach 2:
The patent replaces the mechanical connection and data transmission system with an integrated wireless transmission system. This substitution eliminates the need for physical connectors and reduces the number of procedural steps required for data transmission, thereby simplifying the overall procedure while ensuring reliable data transfer.

AI summary
A sensor wire system with an integrated power source and wireless transmission is provided. A sensor wire includes a distal end that is inserted into a blood vessel of a patient's body. A sensor that is mounted at the distal end of the sensor wire and an electronics unit of the distal end of the sensor wire transmit information generated by the sensor to a receiver unit outside of the patient's body wirelessly. The system further includes a power source, which is a power harvesting device. In one example the power source is mounted to the distal end of the sensor wire, that supplies power to the electronics unit.
