Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple wire connections are used for power and data transmission in intraluminal sensing systems, then reliable power supply and data communication are ensured, but workspace clutter increases and operational complexity increases
Solution Approach 1:
The patent combines multiple separate wire connections for power and data transmission into a single integrated Ethernet cable connection. The PoE (Power over Ethernet) technology merges power delivery and data communication functions into one cable, eliminating the need for separate power adapters and data cables, thus reducing workspace clutter while maintaining reliable power supply and data communication.
Solution Approach 2:
The Ethernet cable is made multi-functional by enabling it to simultaneously perform power transmission and data communication tasks. The PoE infrastructure allows a single universal cable type to serve multiple functions that previously required specialized separate connections, simplifying the system while ensuring reliable operation.
2Reliability
If separate power and data connections are used, then dedicated power supply ensures stable operation, but device complexity and cabling requirements increase
Solution Approach 1:
The patent merges separate power and data connection systems into a unified PoE-based Ethernet connection. This integration reduces device complexity by eliminating multiple connection interfaces and cables while maintaining stable operation through the standardized PoE power delivery protocol that ensures reliable power supply.
Solution Approach 2:
The system adopts a universal Ethernet cable that can simultaneously handle both power delivery and data transmission functions. This multi-functional approach reduces device complexity by standardizing connections while ensuring stable operation through the robust PoE infrastructure designed for reliable power and data delivery.
3Adaptability or versatility
If multiple diagnostic systems are connected via wire to gather medical data, then comprehensive data collection is achieved, but cable management becomes difficult and workspace clutter increases
Solution Approach 1:
The patent replaces the mechanical cable-based connection system with a wireless communication system for connecting multiple diagnostic systems. The intraluminal sensing device communicates data wirelessly to multiple diagnostic systems, eliminating the need for physical cable connections to each system while maintaining comprehensive data collection capabilities and significantly improving cable management.
Solution Approach 2:
The patent extracts the data transmission function from the physical cable medium and transfers it to a wireless communication channel. This allows multiple diagnostic systems to receive medical data without requiring physical cable connections, thereby maintaining adaptability for comprehensive data collection while eliminating cable management difficulties.
