Adaptive Movement Measurement Using Coded Signal Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining the position of objects with high accuracy are hindered by the labor-intensive installation of continuous signal sources along the object's motion path, which is complicated by obstacles and requires precise positioning, leading to error accumulation and increased costs.
Innovation Solution
An adaptive method using uniquely coded signal sources and transducers, where sources are arranged randomly at varying distances and types within the transducer's measurement range, allowing for accurate object positioning without strict coordinate alignment, enabling flexible placement and reduced labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If signal sources are arranged in a continuous array along the object's motion path, then measurement accuracy is improved, but installation complexity and time increase significantly
Solution Approach 1:
The patent divides the continuous measurement path into discrete segments, each marked by individually coded signal sources. Instead of requiring a continuous array of transducers, the system uses segmented, distributed signal sources placed at intervals along the motion path. Each signal source carries unique identification code that allows the transducer to determine position based on which segment's signal it receives, thereby achieving accurate position measurement without the need for dense continuous transducer placement.
2Measurement precision
If signal sources are positioned with strict equal spacing, then measurement accuracy is maintained, but installation time and labor increase
Solution Approach 1:
The patent changes the parameter of signal source spacing from fixed equal intervals to variable intervals. Each signal source is assigned a unique identification code that encodes its position information. This allows signal sources to be placed at variable distances from each other along the motion path while maintaining measurement accuracy, as the transducer can determine position based on the received signal's identification code rather than relying on regular spacing patterns.
3Measurement precision
If obstacles are present along the motion path, then measurement continuity is disrupted, but installing multiple systems to overcome obstacles greatly complicates production
Solution Approach 1:
The patent creates a universal measurement system where individually coded signal sources can be placed independently along the motion path, allowing the same system architecture to handle both obstacle-free and obstacle-present scenarios. The transducer receives signals from whichever signal sources are within its detection range, regardless of obstacles. This universal approach eliminates the need for separate measurement systems for different path configurations, as the coded signal sources provide continuous position information even when obstacles block portions of the path.
4Measurement precision
If signal sources are placed at predetermined positions with strict accuracy, then measurement error accumulation is reduced, but installation labor and precision requirements increase
Solution Approach 1:
The patent implements a self-calibrating system where each signal source carries its own identification code that automatically provides position information to the transducer. The signal sources themselves serve as the reference markers, eliminating the need for external calibration equipment or complex installation procedures. When the transducer receives a signal, it automatically decodes the position information from the signal's identification code, making the system self-sufficient and easy to install without requiring high-precision positioning equipment or complex calibration procedures.

AI summary
The invention can be used for determining absolute movements of objects. The problem to be solved consists in increasing the accuracy of the measurement of movements of an object when obstacles are present in the trajectory of motion thereof by eliminating error accumulation in the positioning of signal sources. A transducer is mounted on an object, separate sources of uniquely coded signals are used and/or groups of sources of a uniquely coded signal are formed, the separate sources of uniquely coded signals and/or formed groups of sources of a uniquely coded signal are placed randomly along the trajectory of movement of the object at any distance between any two consecutively mounted separate sources of a uniquely coded signal and/or between any two formed groups of sources of a uniquely coded signal, said distance not exceeding the measurement range of the transducer, a signal is directed at the moving object having the transducer, an output signal from the transducer regarding the position of the separate sources of uniquely coded signals and/or groups of sources of a uniquely coded signal is received, and the position of the object is determined.
