Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a tracking device is made portable and lightweight for individual products, then ease of operation and portability are improved, but device complexity and security mechanisms must be reduced which compromises tamper resistance
Solution Approach 1:
The tracking device is divided into separate functional modules: a lightweight portable unit attached to the product and a separate tracker unit. This segmentation allows the portable device to remain simple and lightweight while the separate tracker handles complex security and communication functions, resolving the contradiction between portability and tamper resistance.
Solution Approach 2:
A secure communication link acts as an intermediary between the portable tracking device and the remote server. The intermediary ensures that even though the portable device is simple, the communication channel provides the necessary security and tamper detection capabilities, maintaining reliability without increasing device complexity.
2Loss of information
If real-time location tracking is implemented using cellular networks, then location monitoring capability is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous real-time tracking, the system uses periodic location updates at predetermined intervals. This periodic action maintains sufficient location monitoring capability while dramatically reducing energy consumption compared to continuous tracking, resolving the contradiction between information availability and energy use.
Solution Approach 2:
The system leverages existing cellular network infrastructure for location tracking, allowing the portable device to use available network resources without requiring dedicated high-power transmission components. This self-service approach enables location monitoring while minimizing additional energy consumption.
3Adaptability or versatility
If tracking operates across multiple geographic areas including indoors, then adaptability is improved, but signal strength and tracking reliability deteriorate
Solution Approach 1:
The tracking device is designed with universal functionality to operate across diverse geographic areas including indoors and outdoors. The device can switch between different communication modes and network types to maintain operation across multiple environments, improving adaptability while managing signal reliability through multi-functional capabilities.
