Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If UWB channel is used for indoor positioning, then positioning precision is improved, but channel availability deteriorates when mobile terminal does not support UWB module or channel capacity is reduced due to great number of users
Solution Approach 1:
The system supports multiple communication channels (UWB, Wi-Fi, Bluetooth) and can dynamically select among them based on terminal capabilities and environmental conditions. This multi-functionality ensures that the positioning system can operate across diverse device types and network conditions, making the solution universally applicable while maintaining high precision where possible.
Solution Approach 2:
The system dynamically selects communication channels based on real-time conditions including terminal support, user density, and signal quality. This dynamic adaptation allows the system to switch from UWB to alternative channels when necessary, resolving the contradiction between maintaining precision and ensuring availability across varying operational contexts.
2Adaptability or versatility
If multiple communication channels are supported for different mobile terminals, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system introduces a channel selection mechanism that acts as an intermediary between multiple communication channels and the positioning function. This mediator evaluates terminal capabilities and environmental conditions to automatically select the appropriate channel, thereby supporting multiple terminals without requiring each device to implement all communication protocols, thus reducing overall system complexity.
Solution Approach 2:
The system segments the positioning functionality into channel-agnostic core logic and channel-specific communication layers. This segmentation allows the core positioning algorithm to remain simple and universal while handling multiple communication channels through standardized interfaces, reducing the complexity burden on individual components.
3Reliability
If channel selection is based on capacity and precision evaluation, then positioning reliability is improved, but information processing time increases
Solution Approach 1:
The system performs preliminary evaluation of channel characteristics including capacity and precision metrics before actual positioning operations. By pre-assessing channel suitability and maintaining this information for quick reference, the system reduces real-time decision-making overhead while ensuring reliable channel selection based on comprehensive evaluations performed in advance.
