Solution Overview
Problem
Existing positioning systems struggle to adapt to dynamically changing integrity requirements in scenarios like intelligent warehousing and logistics, leading to potential fault events due to preset integrity settings that do not account for real-time changes.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a preset integrity requirement is used, then the positioning system can operate with a fixed integrity level, but it cannot adapt to dynamically changing integrity requirements in different scenarios
Solution Approach 1:
The patent implements dynamic adjustment of positioning integrity requirements based on real-time scenario detection. The system transitions from a static preset integrity level to a dynamic integrity requirement that adapts to different positioning scenarios (e.g., high integrity for charging operations, medium integrity for transportation). This is achieved through scenario judgment modules that continuously monitor the current operation state and adjust integrity parameters accordingly.
Solution Approach 2:
The system changes the integrity parameter dynamically based on the detected scenario. Different integrity levels (high, medium, low) are selected according to the operational context, such as using high integrity when the AGV is approaching a charging pile or performing precision docking, and reducing integrity levels for less critical operations. This parameter adaptation allows the system to meet varying reliability requirements without over-engineering the entire system.
2Reliability
If high positioning integrity is maintained in all scenarios, then reliability is improved, but resource utilization and system efficiency deteriorate
Solution Approach 1:
The patent applies different integrity levels to different local scenarios rather than uniformly across all operations. High integrity is localized to specific critical scenarios (charging, precision docking), while medium or low integrity is applied to less critical scenarios (general transportation, empty running). This localized quality approach ensures that resources are not wasted on unnecessary high-integrity operations while maintaining reliability where it matters most.
Solution Approach 2:
The system uses partial high-integrity action only when and where needed, rather than applying high integrity continuously. By detecting scenarios that require high integrity and activating only those specific high-integrity positioning operations, the system avoids the excessive resource consumption that would result from maintaining high integrity throughout all operations, while still providing the necessary reliability for critical tasks.
3Adaptability or versatility
If the positioning system continuously monitors and adjusts integrity requirements, then adaptability is improved, but device complexity increases
Solution Approach 1:
The positioning device is designed with multi-functionality to handle both scenario detection and integrity adjustment within a single integrated system. The same positioning device that performs location calculation also contains the scenario judgment module and integrity parameter adjustment capabilities. This universal design avoids the need for separate complex systems for scenario detection and integrity management, thereby reducing overall system complexity while maintaining adaptability.
Solution Approach 2:
The positioning system implements self-service through autonomous scenario detection and self-adjustment of integrity parameters. The system automatically monitors its own operational context, detects when high integrity is required, and adjusts its own positioning parameters without external intervention. This self-service capability reduces the need for complex external control systems and manual configuration, simplifying the overall architecture while enabling dynamic adaptability.
