Product Positioning System with Dual-Mode Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing product management systems face challenges in accurately identifying and managing users of products after shipping, particularly when products change hands, as user information is not always actively registered, and positioning accuracy can be low due to environmental limitations in satellite and base station positioning methods.
Innovation Solution
A system that collects and displays position data sets from products using both GNSS and base station positioning, allowing for accurate user estimation by differentiating display modes based on the accuracy of each positioning method, thereby enhancing user identification and product management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If single point positioning (GNSS) is used to determine product position, then positioning accuracy is improved, but reliability deteriorates in environments where satellite signals cannot be received well (indoors or underground)
Solution Approach 1:
The patent combines single point positioning and base station positioning into a unified positioning system. The server selects appropriate positioning results based on accuracy requirements and environmental conditions, merging the strengths of both methods to achieve reliable positioning across diverse scenarios.
Solution Approach 2:
The patent changes the parameter of positioning method selection based on accuracy requirements and signal availability. The server dynamically adjusts which positioning result to use (single point or base station) depending on the specific situation, optimizing both accuracy and reliability.
2Reliability
If base station positioning is used to determine product position, then reliability is improved in communication areas, but measurement precision deteriorates compared to single point positioning
Solution Approach 1:
The patent merges base station positioning with single point positioning, allowing the system to use base station positioning for reliable location estimation when satellite signals are unavailable, while accepting the trade-off in accuracy only when necessary.
Solution Approach 2:
The patent implements dynamic parameter selection where the positioning accuracy parameter is adjusted based on the chosen method. The server selects base station positioning results when reliability is prioritized and single point positioning when maximum accuracy is required and signal conditions permit.
3Measurement precision
If user information is actively registered in the server system, then user identification accuracy is improved, but ease of operation deteriorates as users may not actively register or update information when products change hands
Solution Approach 1:
The patent implements self-service positioning where the positioning function operates automatically without requiring user intervention. The product's positioning capability continuously provides location data, and the server automatically processes this information to identify users, eliminating the need for manual information registration.
Solution Approach 2:
The system uses continuous feedback from position data sets to update user identification. By monitoring position changes and comparing them with registered user locations, the server can automatically identify current users without requiring active registration, creating a closed-loop feedback system.
4Measurement precision
If multiple position data sets are collected and displayed with different frequencies, then user estimation accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic display frequency adjustment where the server selectively displays position data at different frequencies based on the positioning method and accuracy requirements. This dynamic approach improves user estimation accuracy while avoiding the constant complexity of processing all possible data sets uniformly.
Data Source
AI summary
A system receives a first position data set indicating a first positioning position of a shipped product with first frequency and receives a second position data set indicating a second positioning position of the product with second frequency. The system displays, on a map, at least one of n first position display objects respectively indicating n first positions based on N first position data sets and m second position display objects respectively indicating m second positions based on M second position data sets. A display mode for the n first position display objects is different from a display mode for the m second position display objects. The positioning type or the number of satellites is different between the first positioning position and the second positioning position.
