Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning systems face accuracy degradation and failures when Wi-Fi devices are installed randomly or moved, or when GPS signals are weak, as they rely on predetermined anchors and fixed installations.
Innovation Solution
A method and apparatus for establishing a self-organized and scalable positioning network by sensing other apparatuses in a space, determining their positions relative to each other, and communicating this information to establish a positioning network without pre-defined anchors, using protocols like TCP/IP and UDP for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If predetermined anchors and fixed installations are used for positioning, then positioning accuracy is maintained, but system adaptability and ease of deployment deteriorate when devices are moved or randomly installed
Solution Approach 1:
The patent transforms the static positioning system into a dynamic one where apparatuses continuously sense each other's positions and update their locations in real-time. Instead of relying on fixed predetermined anchors, the system adapts to device movements by having each apparatus independently determine its position based on current sensing data from neighboring apparatuses, enabling the positioning network to dynamically adjust to changing device locations while maintaining accuracy
Solution Approach 2:
Each apparatus in the positioning network performs self-positioning by sensing other apparatuses and calculating its own location relative to them. The system is self-organizing and self-updating, where apparatuses automatically sense, determine positions, and communicate location information without requiring external reconfiguration or predetermined anchor setup, enabling the network to adapt to random installations and device movements
2Reliability
If predetermined anchors are used for positioning, then positioning reliability is ensured, but system complexity and deployment difficulty increase when devices need to be moved or reinstalled
Solution Approach 1:
The positioning system operates autonomously where each apparatus independently senses other apparatuses, determines relative positions, and communicates location information. The system self-organizes into a positioning network without requiring external configuration or predetermined anchor setup, automatically adapting to any installation scenario while maintaining reliability through continuous mutual sensing and position verification among apparatuses
Solution Approach 2:
The system transitions from a static configuration requiring predetermined anchors to a dynamic self-organizing network where apparatuses continuously update their positions based on real-time sensing. This dynamic approach maintains positioning reliability by having apparatuses constantly verify each other's locations while eliminating the complexity of preconfiguration and reconfiguration when devices are moved
3Measurement precision
If fixed installation positioning systems are used, then initial positioning accuracy is achieved, but scalability and flexibility deteriorate when adding or moving devices
Solution Approach 1:
The patent creates a dynamic positioning network where apparatuses continuously sense each other and update positions in real-time. When new apparatuses are added or existing ones move, the system automatically adapts through continuous mutual sensing and position determination, maintaining accuracy without requiring reconfiguration or predetermined anchor setup, enabling seamless scalability and flexibility
Solution Approach 2:
Each apparatus in the network serves multiple functions: it acts as both a position source and a position target, simultaneously sensing other apparatuses while being sensed by them. This universal role assignment enables any apparatus to contribute to the positioning of any other apparatus, creating a scalable and flexible network where devices can be added or moved without disrupting the overall positioning accuracy
