Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If location information is acquired frequently to ensure position accuracy, then measurement precision is improved, but use of energy by moving object increases and loss of energy worsens
Solution Approach 1:
The system implements periodic positioning by setting a positioning interval parameter that determines how frequently location information is acquired. The CSE sends positioning requests at regular intervals rather than continuously, which maintains position accuracy within acceptable bounds while significantly reducing energy consumption compared to continuous positioning. This periodic action allows the M2M node to enter low-power states between positioning events.
Solution Approach 2:
The system changes the positioning parameters dynamically by allowing the positioning interval and positioning duration to be configured based on application requirements. By adjusting these parameters, the system optimizes the balance between position accuracy and energy consumption - longer intervals reduce energy use while shorter intervals improve accuracy, enabling adaptive parameter tuning for different operational scenarios.
2Reliability
If location information is acquired continuously to maintain real-time position data, then reliability is improved, but loss of time increases due to frequent resource allocation
Solution Approach 1:
The system uses periodic positioning requests instead of continuous acquisition, where the CSE sends location requests at configured intervals. This maintains sufficient reliability for most M2M applications while eliminating the constant overhead of continuous positioning, thereby reducing time loss associated with frequent resource allocation and network communications.
Solution Approach 2:
The system performs preliminary configuration of positioning parameters (interval and duration) before actual positioning begins. This allows the system to pre-plan resource allocation and avoid repeated negotiation overhead during operation, reducing time loss while maintaining reliable position data acquisition throughout the positioning duration.
3Measurement precision
If positioning requests are sent frequently to update location data, then measurement precision is improved, but device complexity increases due to more frequent protocol operations
Solution Approach 1:
The system reduces protocol operation frequency by implementing periodic positioning with configurable intervals. Instead of frequent positioning requests that increase device complexity, the CSE sends requests at optimized intervals that maintain measurement precision while significantly reducing the number of protocol operations, message exchanges, and processing events required.
4Adaptability or versatility
If location information acquisition is performed without control to ensure data availability, then adaptability is improved, but loss of energy and resources increases
Solution Approach 1:
The system implements dynamic control of positioning by allowing the CSE to adjust positioning parameters (interval and duration) based on application needs and network conditions. This dynamic adaptability ensures location data is available when needed while avoiding unnecessary positioning operations, thereby reducing energy loss and resource consumption compared to uncontrolled continuous acquisition.
Solution Approach 2:
The system uses configurable positioning parameters to adapt positioning behavior to different scenarios. By changing parameters like positioning interval and duration based on application requirements, the system maintains necessary data availability while avoiding unnecessary positioning operations that would waste energy and resources.
