Indoor Navigation Map Generation Using Wireless Shelf Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation map generation methods for indoor spaces, such as shopping malls and warehouses, are cumbersome, inefficient, and lack accuracy due to the manual drawing of article positions, which is time-consuming and prone to errors.
Innovation Solution
A map generation system that employs wireless apparatuses placed on each article shelf, where a handheld terminal scans the articles and sends scanning information to a server, which uses the wireless apparatus positions to generate a navigation map automatically, eliminating the need for manual drawing and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual drawing method is used to create navigation map, then the map can be generated, but the process is cumbersome and time-consuming
Solution Approach 1:
The patent replaces the manual mechanical drawing operation with an automated electronic system. The handheld terminal scans articles and the server automatically generates the navigation map using scanned data and wireless apparatus positions, eliminating the need for manual drawing and significantly improving efficiency.
Solution Approach 2:
The system enables self-service map generation where the handheld terminal and server automatically collect data and generate the navigation map without requiring manual intervention. The scanning process and map generation are automated, allowing the system to serve itself in creating accurate navigation maps.
2Measurement precision
If manual drawing method is used to create navigation map, then the map can be generated, but the accuracy is insufficient
Solution Approach 1:
The patent introduces wireless apparatus as intermediaries placed on article shelves that provide precise position information. These intermediaries enable the system to automatically obtain accurate article positions without manual measurement, significantly improving measurement precision while the automation reduces the perceived complexity.
Solution Approach 2:
The system creates an accurate digital copy of the physical article positions through scanning and wireless apparatus data. This digital representation accurately reflects the real-world layout, enabling precise navigation map generation that mirrors the actual article placements.
3Adaptability or versatility
If articles are frequently moved and reorganized, then the inventory flexibility is improved, but the navigation map becomes outdated quickly
Solution Approach 1:
The patent implements a dynamic system where the navigation map can be automatically updated by scanning articles at their new positions. The handheld terminal and server work together to detect position changes and regenerate the map, making the system adaptable to frequent reorganizations while maintaining reliability.
Solution Approach 2:
The system incorporates feedback mechanisms where the scanning process continuously monitors article positions and provides information to the server for map updates. This feedback loop ensures the navigation map remains accurate even when articles are frequently moved or reorganized.
