Position Measurement Device Boundary Verification Region Scan
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing position measurement techniques require long scan times and are unable to detect targets entering a specific area in real time, as they scan all sections of the area until a target is discovered, leading to delayed measurement.
Innovation Solution
A position measurement device that sets a verification region along the boundary of a specific area, performs position measurement within this region, and updates area information to quickly detect and measure targets entering the area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If position measurement is performed for all sections in a specific area, then measurement coverage is complete, but scan time becomes long
Solution Approach 1:
The patent divides the specific area into multiple sections and performs position measurement for each section sequentially. This segmentation allows the system to process a limited number of sections at each measurement cycle, reducing the time required for complete area coverage while maintaining comprehensive measurement capability over multiple cycles.
Solution Approach 2:
The patent implements periodic position measurement across different sections of the specific area. By cycling through sections in a periodic manner rather than measuring all sections continuously in one pass, the system reduces instantaneous scan time while ensuring complete coverage over time through repeated measurement cycles.
2Reliability
If all sections are scanned until a target is discovered, then detection thoroughness is ensured, but time to detect newly entering targets is delayed
Solution Approach 1:
The patent performs position measurement for a limited number of sections before a target is discovered, rather than waiting to scan all sections. This preliminary action enables the system to detect newly entering targets more quickly by not delaying detection until complete area coverage is achieved, while still maintaining detection thoroughness through continued periodic measurements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach significantly reduces the time required to detect targets entering the area and enables real-time position measurement by limiting the scan area to a verification region, thereby shortening the overall scan time.
Implementation Method 1
receiving a reflected wave of an electromagnetic wave transmitted toward a range including a specific area
Implementation Method 2
NPL 1 discloses a tracking technique of scanning all sections of a specific area, and, when a target is discovered, performing position measurement by restricting a scan range to a region including the target
