Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional galvanic contacts are used for battery charging and data transfer, then electrical connection is established, but contact resistance and hygiene issues occur
Solution Approach 1:
The patent replaces the mechanical galvanic contact system with a magnetic coupling system. The magnetic coupling unit uses magnetic fields to transfer power and data wirelessly between the battery module and the monitoring device, eliminating the need for physical electrical contacts. This substitution resolves the contact resistance and hygiene issues while maintaining reliable electrical connection functionality.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary medium for power and data transfer. The magnetic coupling unit generates magnetic fields that penetrate through the housing to establish communication and power transfer between the battery module and the monitoring device without direct physical contact, thus avoiding contamination and contact resistance problems.
2Ease of operation
If multiple charging stations and connectors are used for battery management, then battery charging is possible, but workflow disruptions occur
Solution Approach 1:
The patent implements a universal magnetic coupling interface that can charge and communicate with any compatible monitoring device in the system. The battery module uses the same magnetic coupling unit for both power transfer and data exchange, eliminating the need for multiple specialized charging stations and connectors. This universal interface allows seamless integration into clinical workflows without requiring staff to learn or adapt to different charging mechanisms.
3Reliability
If wireless power transfer is implemented, then galvanic contacts are eliminated, but precise positioning is required
Solution Approach 1:
The patent employs periodic detection and adjustment of the magnetic coupling strength to maintain optimal positioning. The system periodically monitors the coupling status and provides feedback to guide the user in adjusting the position of the battery module relative to the monitoring device, ensuring sufficient magnetic coupling without requiring precise manual positioning. This periodic action reduces the complexity of positioning requirements while maintaining electrical safety through wireless transfer.
