Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wire communication method is adopted, then data transmission reliability is improved, but user comfort deteriorates due to cable contact with skin and potential disconnection
Solution Approach 1:
The system is divided into a sensing unit (attached to body) and a data holding unit (external device), separated by a cable. This segmentation allows the sensing unit to remain minimally invasive while transmitting data wirelessly to the external device, eliminating cable contact with the patient's body.
Solution Approach 2:
The patent replaces the mechanical cable connection with a wireless communication system. The sensing unit contains a wireless transmission device that sends data to the data holding unit without physical cable connection, eliminating the harmful mechanical contact between cable and patient skin.
2Object-affected harmful factors
If a radio communication method is adopted, then user comfort is improved, but data transmission accuracy deteriorates due to interference with other devices
Solution Approach 1:
The patent introduces a dedicated wireless communication channel as an intermediary between the sensing unit and data holding unit. This dedicated channel isolates the medical data transmission from general radio frequency interference, ensuring accurate data transfer while maintaining wireless convenience.
3Reliability
If a cable is used for data transmission, then data transmission stability is improved, but system adaptability deteriorates due to potential disconnection and limited movement
Solution Approach 1:
The system transitions from a static cable connection to a dynamic wireless connection. The sensing unit can be freely positioned and moved on the patient's body without cable constraints, while the wireless communication maintains stable data transmission through electromagnetic field coupling between the sensing unit and data holding unit.
