Solution Overview

Problem

Existing technologies for controlling movable platforms, such as UAVs, lack accurate methods to determine their relative position with respect to designated movable and prohibited movement areas, leading to potential unsafe accidents.

Innovation Solution

A method that involves determining a first area as a movable area and a second area as a prohibited movement area, obtaining platform positions within these areas, and calculating relative positions to implement control strategies ensuring safe operation based on these positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the distance between UAV location and no-fly area is used to determine relative position, then the control method is simple, but the position determination accuracy is insufficient leading to potential unsafe accidents

Engineering Contradiction:
Improveposition determination accuracyVSAvoidcontrol method complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The spatial set is segmented into multiple discrete regions (first area, second area, third area) with different safety levels. Instead of treating the space as continuous, the method divides it into zones where each zone has specific control requirements, enabling more precise position determination while maintaining manageable control logic through regional classification

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from one-dimensional distance measurement to two-dimensional spatial region classification. By introducing area-based positioning with multiple zones radiating from the no-fly area, the system achieves higher position determination accuracy by utilizing angular and radial dimensions simultaneously, rather than relying solely on radial distance

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Measurement precision

If comprehensive area division and relative position calculation are implemented, then position determination accuracy is improved, but the computational complexity increases

Engineering Contradiction:
Improverelative position determination accuracyVSAvoidcomputation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The control device pre-establishes the spatial set, divides it into multiple regions, and sets no-fly areas before operation begins. This preliminary configuration allows the system to avoid real-time complex calculations by simply determining which pre-defined region the UAV occupies, significantly reducing computation time while maintaining high position determination accuracy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts control strategies based on the UAV's real-time position within different regions. Rather than using static control parameters, the method adapts control actions according to which pre-defined region the UAV is in, enabling efficient real-time control with reduced computational burden while maintaining high positioning accuracy

Inventive Principle:
Principle #15Dynamics
