Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If medical device trays are shipped without tracking capability, then shipping cost and device complexity are minimized, but loss of trays increases significantly
Solution Approach 1:
The patent introduces a third-party intermediary service provider that operates a centralized database and wireless network infrastructure. This intermediary handles the complex tracking infrastructure requirements, allowing the medical device manufacturer to avoid building and maintaining their own tracking system while still achieving reliable tray location monitoring through the intermediary's established platforms.
Solution Approach 2:
The patent uses wireless communication signals (electromagnetic waves) to create information copies of the tray's location data. The tracking device transmits location information wirelessly to the intermediary's database, creating digital replicas of the physical tray's position that can be accessed remotely without physically tracking the actual device, thus reducing complexity while maintaining reliability.
2Productivity
If tracking devices are attached to medical device trays, then tray recovery and procedural efficiency improve, but device complexity and initial cost increase
Solution Approach 1:
The tracking device is designed to be a universal solution that can be attached to any medical device tray regardless of the specific medical procedure or tray contents. The device performs multiple functions including location tracking, wireless communication, and data storage, allowing a single standardized device to serve diverse medical applications and justify its cost through broad applicability and efficiency gains across multiple procedures.
Solution Approach 2:
The tracking device operates autonomously once attached to the tray, automatically transmitting location data through wireless networks without requiring manual intervention. The device self-manages power consumption, data transmission timing, and communication protocols, reducing the operational burden on medical staff and allowing the productivity benefits to be realized without proportionally increasing operational complexity.
3Loss of energy
If real-time tracking is implemented, then loss prevention and financial impact are reduced, but energy consumption and device complexity increase
Solution Approach 1:
The tracking device transmits location data periodically rather than continuously, sending updates at predetermined time intervals or when triggered by specific events such as movement detection. This periodic transmission pattern significantly reduces power consumption compared to continuous monitoring while still providing timely location information to prevent financial losses from tray misplacement or loss.
Solution Approach 2:
The tracking device can dynamically adjust its operational parameters such as transmission frequency, power mode, and communication protocol based on current conditions. For example, the device may switch to lower-power modes when stationary and increase transmission frequency when movement is detected, optimizing the balance between loss prevention and energy consumption by changing operational parameters rather than maintaining fixed high-energy settings.
