Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large area spaces, such as construction sites, face challenges in tracking and locating static objects due to the inefficiency of current methods, which often rely on low-resolution images or require multiple expensive devices to transmit signals simultaneously.
Innovation Solution
A method using a single instrument to determine the location of a static object by serially transmitting omnidirectional signals from different locations at different times, employing trilateration techniques to calculate distances and ultimately pinpoint the object's location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple devices transmit signals simultaneously, then location determination accuracy is improved, but device complexity and cost increase
Solution Approach 1:
The patent segments the location determination process into multiple sequential time steps, where a single instrument performs measurements at different locations and times. This replaces the need for multiple simultaneous devices with one device performing segmented measurements, thereby reducing device complexity while maintaining location accuracy through trilateration
Solution Approach 2:
The patent employs periodic action by having the single instrument transmit signals at different times from different locations. The instrument performs repeated measurements at scheduled intervals, allowing location determination through time-sequenced data collection rather than requiring multiple simultaneous devices
2Measurement precision
If high-resolution imaging is used to locate objects, then location precision is improved, but time consumption and cost increase
Solution Approach 1:
The patent replaces the mechanical/optical imaging system with an electromagnetic signal-based measurement system. Instead of using cameras or visual inspection methods that require high-resolution imaging, the system uses electromagnetic signals and trilateration mathematics to determine location, significantly reducing time while maintaining precision
Solution Approach 2:
The patent introduces an intermediary computational process that uses signal travel time and distance calculations to determine location. This intermediary mathematical model transforms raw signal measurements into precise location data without requiring direct visual imaging, thereby reducing time consumption while maintaining accuracy
3Device complexity
If a single instrument is used for serial measurements, then device cost is reduced, but measurement time increases
Solution Approach 1:
The patent applies dynamics by optimizing the instrument's movement and measurement sequence. The instrument dynamically adjusts its measurement locations and timing to minimize total measurement time while collecting sufficient data for accurate trilateration, balancing the trade-off between using one device and measurement duration

AI summary
A method and apparatus for determining the location of an object with a sensor positions an instrument at a first location, controls the instrument to transmit a first omnidirectional signal during a first time, and determines a first distance from the instrument to the static object using the first omnidirectional signal. The method and apparatus repeats this process in a serial manner at two other locations, and uses the respective distances from each location to determine the location of the object. Other embodiments are disclosed.
