Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS module is used to provide position information, then position accuracy is improved, but power consumption increases
Solution Approach 1:
The electronic device employs multiple positioning modules (GPS, cellular communication module, Wi-Fi module) that can serve different positioning needs. The system selectively activates appropriate modules based on application requirements and environmental conditions, allowing one system to fulfill multiple positioning functions rather than relying solely on GPS for all scenarios.
Solution Approach 2:
The system dynamically changes positioning parameters by switching between different positioning methods (GPS-based positioning, cellular-based positioning, Wi-Fi-based positioning) according to the specific requirements of running applications. This allows optimization of power consumption by using lower-power positioning methods when high precision is not required.
2Reliability
If GPS module is used in shadow areas, then position information is provided, but reliability deteriorates due to signal loss
Solution Approach 1:
When GPS signal is unavailable in shadow areas, the system uses cellular communication modules and Wi-Fi modules as intermediary positioning methods. These alternative modules can obtain position information through network-based positioning techniques, serving as mediators to provide position data when direct GPS satellite signals are blocked.
Solution Approach 2:
The system dynamically switches between different positioning modules based on real-time conditions. When GPS is unavailable in shadow areas, the system automatically transitions to alternative positioning methods (cellular or Wi-Fi positioning), making the positioning system adaptive to environmental conditions rather than static.
3Use of energy by moving object
If multiple positioning modules are used to reduce power consumption, then device complexity increases
Solution Approach 1:
The control module automatically manages the complexity of multiple positioning modules by implementing intelligent selection algorithms. The system self-determines which positioning method to use based on application requirements and environmental conditions without requiring manual configuration or complex user intervention, thereby managing system complexity through automated decision-making.
Solution Approach 2:
The system incorporates feedback mechanisms where the control module continuously monitors positioning performance, power consumption, and application requirements to dynamically adjust which positioning module is active. This feedback loop allows the system to optimize the balance between power consumption and positioning accuracy without requiring complex manual management.
