Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If existing tracking systems are used for asset and inventory management, then tracking functionality is provided, but power consumption is high and efficiency is low
Solution Approach 1:
The RF processor transmits identification signals periodically at adjustable intervals rather than continuously, allowing the system to maintain tracking functionality while significantly reducing power consumption during idle periods
Solution Approach 2:
The system dynamically adjusts the transmission interval based on operational conditions, transitioning between active transmission and low-power states to optimize the balance between tracking efficiency and power consumption
2Reliability
If continuous broadcasting is used to maintain tracking signals, then tracking accuracy is improved, but battery life is reduced
Solution Approach 1:
The identification signal is transmitted in periodic bursts rather than continuously, maintaining sufficient tracking accuracy for operational needs while extending battery life by eliminating unnecessary continuous transmission
Solution Approach 2:
The system incorporates feedback mechanisms that adjust transmission frequency based on detected movement or operational status, ensuring tracking accuracy is maintained when needed while conserving battery power during stable conditions
3Adaptability or versatility
If complex existing tracking systems are deployed, then comprehensive tracking functionality is achieved, but manufacturing cost increases
Solution Approach 1:
The wireless tape label integrates multiple functions including identification signaling, movement detection, and wireless communication into a single universal component, eliminating the need for separate tracking devices and reducing overall system manufacturing cost
Solution Approach 2:
The system combines the identification signal generator, sensor elements, and wireless transceiver into an integrated circuit on the wireless tape label, simplifying the overall system architecture and reducing manufacturing complexity
