Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional manual activation process is used, then label can be activated, but time consumption and device requirements increase
Solution Approach 1:
The patent replaces manual mechanical activation with automated optical detection. A light sensor detects light impulses that trigger automatic activation of the radio label, eliminating the need for manual device operation and significantly reducing activation time
Solution Approach 2:
The radio label activates itself automatically upon detecting a light impulse, without requiring external manual intervention. The system performs self-activation and self-programming, reducing both time consumption and the number of devices needed in the activation process
2Reliability
If continuous radio transmission is enabled, then tracking capability is maintained, but battery life is reduced
Solution Approach 1:
The radio label transmits data periodically rather than continuously. The microcontroller is programmed to transmit identification and location information at predetermined time intervals, which maintains tracking capability while significantly reducing power consumption compared to continuous transmission
Solution Approach 2:
The system dynamically adjusts transmission parameters including time intervals and data content based on operational needs. Transmission frequency and duration are modified to optimize the balance between tracking reliability and battery conservation
3Ease of operation
If multiple devices are used for activation, then activation can be performed, but process complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated system. The light sensor, microcontroller, and radio transmitter are merged into one device that can detect activation signals, process information, and transmit data autonomously, eliminating the need for separate manual activation devices
Solution Approach 2:
The radio label system is designed to perform multiple functions: detecting light impulses, receiving programming data, storing information in memory, and transmitting radio signals. This multi-functionality reduces the need for multiple specialized devices in the activation and operation process
