Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional methods are used to determine positions of stationary units, then positioning accuracy can be achieved, but the setup process becomes very laborious and time-consuming
Solution Approach 1:
The localization system performs self-localization by having stationary radio transmitters determine their own positions autonomously. The system uses mobile radio modules integrated in stationary transmitters to perform coarse localization, then refines positions through fine localization using ultra-wideband technology, eliminating the need for manual positioning operations.
Solution Approach 2:
The patent replaces manual mechanical positioning operations with automated electronic localization methods. Instead of physically measuring and marking positions manually, the system uses radio-based coarse localization followed by ultra-wideband fine localization to automatically determine positions with high precision.
2Productivity
If manual positioning methods are used for stationary units, then position determination can be completed, but the process becomes inefficient and labor-intensive
Solution Approach 1:
The system enables stationary radio transmitters to automatically determine their own positions through integrated mobile radio modules. The transmitters autonomously perform coarse localization via mobile radio networks and fine localization using ultra-wideband technology, dramatically improving setup efficiency without requiring manual intervention.
Solution Approach 2:
The system performs preliminary coarse localization using mobile radio technology before conducting fine localization with ultra-wideband technology. This two-stage approach prepares the positioning framework in advance, making the subsequent precise positioning more efficient and simpler to execute.
3Ease of operation
If coarse localization is performed via mobile radio, then initial positioning can be achieved, but positioning precision needs improvement
Solution Approach 1:
The localization process is divided into two distinct stages: coarse localization using mobile radio technology for initial positioning, and fine localization using ultra-wideband technology for precision refinement. This segmentation allows each stage to optimize for its specific function while achieving overall high accuracy.
Solution Approach 2:
The mobile radio-based coarse localization serves as an intermediary step that provides initial position estimates. These intermediate results are then refined by the ultra-wideband fine localization system, which uses the coarse positions as a starting point to achieve final high-precision positioning.
