Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cables are used for signal transmission and power supply, then reliable signal transmission is achieved, but device complexity and portability are reduced
Solution Approach 1:
The patent replaces the mechanical cable-based signal transmission system with a wireless communication system using electromagnetic waves. The PIM includes a wireless transceiver that communicates with the external processing system without physical cable connections, eliminating the need for complex cable assemblies while maintaining signal transmission reliability through standardized wireless protocols.
Solution Approach 2:
The patent introduces an intermediary wireless communication channel between the PIM and the external processing system. This wireless channel acts as a mediator that transfers signals without direct physical contact, replacing the cable intermediary and enabling cable-free operation while preserving communication reliability.
2Power
If large power cables are used to meet high power requirements, then sufficient power supply is achieved, but portability is reduced
Solution Approach 1:
The patent replaces the mechanical power cable system with a wireless power transmission system. The PIM includes a wireless power receiver that accepts power wirelessly from an external transmitter, eliminating the need for bulky power cables and large connectors while providing sufficient power capacity to meet the device's energy requirements.
3Stability of the object's composition
If traditional wired systems are used, then signal transmission is stable, but electrical noise and electromagnetic interference occur
Solution Approach 1:
The patent replaces the wired electrical signal transmission system with a wireless electromagnetic communication system. This substitution eliminates the electrical noise and electromagnetic interference that arise from cable-based transmissions, as the wireless communication uses radio frequency waves that are less susceptible to electrical interference and ground loops.
4Reliability
If isolation components are added to protect patients from high power, then patient safety is improved, but device complexity increases
Solution Approach 1:
The patent replaces the isolated electrical power connection system with a wireless power transmission system. The wireless power transfer inherently provides galvanic isolation between the high-voltage power source and the patient-contacting PIM, eliminating the need for additional isolation transformers and safety components while maintaining patient protection.
