Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for laying out construction sites using fiberglass measuring tapes are time-consuming, prone to measurement errors, and lack precision, leading to incorrect installation of structural components, while electronic positioning systems are not accurate enough for exclusive reliance.
Innovation Solution
A rotating antenna array system that captures location information from multiple antennas positioned around a pivot point, using signals from GPS, ultrawide band, Bluetooth, RFID, radio beacon, sonar, and WiFi to determine a cumulative average position, reducing errors and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fiberglass measuring tape is used to measure distances and mark locations, then the method is simple and requires minimal equipment, but the measurement precision and consistency deteriorate due to human error, weather conditions, and time-consuming re-measuring
Solution Approach 1:
The patent replaces the mechanical fiberglass measuring tape system with an electronic positioning system using multiple antennas and signal processing. The system uses electromagnetic signals (GPS, ultrawide band, bluetooth, RFID, radio beacon, sonar, radar, and wifi) to automatically determine positions, eliminating the need for manual mechanical measurement and thereby improving measurement precision while maintaining ease of operation.
2Productivity
If electronic positioning systems are used to help in the measurement and layout process, then the speed and automation improve, but the measurement precision deteriorates because these systems are not accurate enough to be exclusively relied on
Solution Approach 1:
The patent merges multiple electronic positioning systems and multiple antenna arrays into a single integrated system. By combining signals from GPS, ultrawide band, bluetooth, RFID, radio beacon, sonar, radar, and wifi through a position engine that calculates cumulative averages, the system achieves both high productivity (automated measurement) and high measurement precision (accurate positioning within 1/8 inch or 3 mm), resolving the contradiction between speed and accuracy.
3Measurement precision
If multiple antennas are rotated to multiple stopping points to capture location information, then the measurement precision improves through cumulative averaging, but the device complexity and time required increase
Solution Approach 1:
The patent employs a dynamic rotating antenna array system where antennas can be rotated to multiple stopping points to capture location information from different positions. The position engine dynamically processes signals from each antenna at each stopping point and calculates cumulative average positions. This dynamic approach improves measurement precision by averaging out errors, while the automated rotation and processing minimize the increase in operational complexity.

AI summary
A method and system for determining a position using a rotatable antenna array is provided. The method and system may include receiving first location information at a first stopping point by one or more antenna of a rotatable antenna array, the first stopping point of each of the one or more antenna being different, rotating the one or more antenna from the first stopping point to a second stopping point using the rotatable antenna array, receiving second location information at the second stopping point by the one or more antenna of the rotatable antenna array, the second stopping point of each of the one or more antenna being different, and determining an average location using the first location information and the second location information.
