Position Detection System Using Minimum Distance Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position detection systems face inefficiencies in measuring the positional coordinates of multiple transmitters/receivers, particularly when distances are long or the number of devices is large, leading to reduced measurement efficiency and increased time.
Innovation Solution
The system measures distances among transmitters/receivers multiple times, calculates minimum values, and uses these to determine angles between adjacent lines, with processing to validate true values based on angle differences within triangles formed by these lines, allowing for automatic measurement of distances and coordinates without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurement of positional coordinates is performed using a measuring tape, then measurement accuracy can be ensured, but measurement efficiency decreases and time consumption increases when distances are long or the number of devices is large
Solution Approach 1:
The patent replaces the mechanical measuring tape system with an automated electronic measurement system. The measurement unit automatically measures distances between transmitters/receivers using electronic signals, eliminating the need for manual operation of measuring tapes. This substitution maintains measurement accuracy while dramatically improving efficiency, especially when measuring multiple devices over long distances.
Solution Approach 2:
The measurement system performs self-measurement by automatically determining the positional coordinates of transmitters/receivers without requiring manual intervention. The system autonomously measures distances, calculates coordinates, and stores data, enabling the system to serve itself in the measurement process rather than requiring external human operation.
2Ease of operation
If manual measurement of positional coordinates is performed, then measurement process can be completed, but time consumption increases when the number of transmitters/receivers is large
Solution Approach 1:
The patent replaces manual measurement operations with an automated electronic measurement system. The measurement unit automatically measures distances between all transmitters/receivers and calculates their positional coordinates without requiring human intervention, significantly reducing the time required for coordinate measurement while maintaining operational simplicity through automated processes.
Solution Approach 2:
The measurement system operates continuously to measure all transmitters/receivers in the monitoring area without interruption. The system automatically sequences through all devices, measuring distances and calculating coordinates in a continuous process rather than requiring repeated manual setup and measurement for each device individually.

AI summary
In a position detection system that has a plurality of transmitters/receivers placed at least three positions: processing is executed to measure distances among the plurality of transmitters/receivers, each distance being measured a plurality of times, and obtain a minimum value for each distance; processing is executed to obtain an angle between each two adjacent straight lines, each of which is one of straight lines that mutually connect the plurality of transmitters/receivers, by using minimum values, each of which is the minimum value for each distance; and if the absolute value of the difference between 180 degrees and the sum of angles, each of which is the angle between each two adjacent straight lines, inside a triangle formed by straight lines that interconnect three of the plurality of transmitters/receivers is smaller than a predetermined value, processing is executed to take the minimum values as the true values of the distances.
