Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems for autonomous vehicles are limited in their ability to accurately navigate complex environments, as they often rely on obstacle detection and infrared patterns that can be disrupted by objects, making it difficult for vehicles to track their location and move independently in cluttered spaces.
Innovation Solution
A navigation control system that includes a transmitter emitting signals, a power source capable of wireless charging, and a receiver on the autonomous vehicle that uses these signals to determine its relative location within a working area, allowing it to navigate effectively by calculating azimuth and elevation angles and creating a map of its environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If infrared or other detectors are used to sense nearby walls, obstacles, or objects, then the vehicle can detect objects in its immediate vicinity, but the vehicle cannot accurately track its location within a room or other working environment
Solution Approach 1:
The patent transitions from two-dimensional obstacle detection (sensing nearby objects in the immediate vicinity) to three-dimensional location tracking (determining position within a room or working environment). The system uses multiple transmitters positioned at different locations and angles, allowing the vehicle to calculate its precise position through triangulation based on signal strength measurements from multiple sources, thereby achieving accurate location tracking throughout the entire working space.
2Adaptability or versatility
If infrared patterns are dispersed around the autonomous vehicle, then the vehicle can navigate around an entire area, but the system is disrupted by objects present in the working space
Solution Approach 1:
The system continuously monitors the strength and characteristics of infrared signals from multiple transmitters and uses this feedback to dynamically adjust navigation decisions. By comparing expected signal patterns with actual received signals, the vehicle can detect disruptions caused by objects and compensate for them, maintaining reliable navigation even in cluttered environments. The feedback mechanism allows the system to adapt to changing environmental conditions and maintain accurate location tracking.
3Measurement precision
If multiple transmitters are used to emit coded signals, then the vehicle can differentiate between areas and improve location accuracy, but the device complexity increases
Solution Approach 1:
The patent implements a universal navigation system where multiple transmitters use identical infrared LEDs and modulation techniques, allowing the same hardware component to serve multiple functions: area differentiation, location tracking, and environmental mapping. Each transmitter emits coded signals that can be recognized and processed by the vehicle's receiver, enabling the system to achieve high location accuracy without requiring fundamentally different hardware for each transmitter, thereby managing complexity through functional uniformity.
