Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual user intervention is required to select and install positioning programs, then positioning accuracy can be maintained, but device complexity and ease of operation deteriorate
Solution Approach 1:
The terminal automatically performs closed positioning without requiring user intervention to select or install positioning programs. The system self-services by autonomously determining the terminal's location in closed space and executing the appropriate positioning algorithm, thereby eliminating manual operations while maintaining positioning accuracy.
Solution Approach 2:
The terminal pre-acquires positioning programs and map data for multiple closed spaces before actual positioning is needed. When the terminal enters a closed space, the appropriate positioning program is already available for immediate execution, eliminating the need for manual selection and installation during the positioning process.
2Measurement precision
If multiple closed positioning programs are installed for different closed spaces, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The terminal employs a unified positioning system that can automatically adapt to different closed spaces. Instead of requiring separate dedicated programs for each closed space, the system uses a universal positioning framework that selects and executes the appropriate positioning algorithm based on the detected closed space, thereby reducing the number of installed programs while maintaining positioning accuracy across diverse environments.
Solution Approach 2:
The terminal pre-acquires positioning programs and map data for multiple closed spaces and stores them locally. This preliminary preparation eliminates the need for manual installation during operation, reducing system complexity by having all necessary components readily available without requiring complex installation management.
3Ease of operation
If automatic closed positioning is implemented, then ease of operation is improved, but reliability may deteriorate due to automated selection errors
Solution Approach 1:
The automatic closed positioning system incorporates feedback mechanisms to verify the correctness of automated program selection. The terminal continuously monitors positioning results and environmental characteristics, comparing them against expected patterns to confirm that the selected positioning program is appropriate. This feedback loop ensures reliability by detecting and correcting potential selection errors automatically.
Solution Approach 2:
The terminal performs preliminary verification of the selected positioning program against the detected closed space characteristics before execution. By pre-checking compatibility between the identified closed space and the selected positioning program, the system ensures reliable operation while maintaining automation, preventing erroneous program selection before it can affect positioning accuracy.
