Problem
Current personal vehicle control devices lack the ability to automatically detect and respond to key environmental features, such as obstacles and stairs, which limits their safety and reliability in navigating complex environments.
Innovation Solution
A user control device equipped with a processor that receives user input and sensor data to generate movement commands, utilizing a point cloud library and simultaneous location and mapping to navigate through doors, stairs, elevators, and parking scenarios, and store or recharge the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual control methods are used for personal vehicles, then device complexity is reduced, but the ability to automatically detect and respond to environmental features is lost
Solution Approach 1:
The patent introduces a processor as an intermediary between sensors and actuators. The processor receives sensor data, processes it to identify environmental features, generates appropriate commands, and sends them to actuators. This intermediary component enables automatic detection and response while managing system complexity through modular architecture.
Solution Approach 2:
The personal vehicle is equipped with sensors that automatically detect environmental features and a processor that autonomously generates control commands without requiring continuous user input. The system serves itself by independently perceiving the environment and making navigation decisions, reducing the need for manual intervention.
2Reliability
If automated environmental detection is implemented, then safety and reliability are improved, but device complexity increases
Solution Approach 1:
The patent segments the control system into distinct functional modules: sensors for detecting environmental features, a processor for analyzing sensor data and generating commands, and actuators for executing commands. This segmentation allows each component to be optimized independently while working together to improve safety and reliability.
Solution Approach 2:
The system implements feedback by continuously monitoring environmental features through sensors and adjusting control commands based on detected conditions. The processor receives ongoing sensor data, compares it with desired navigation goals, and generates corrective commands to maintain safe and reliable operation in dynamic environments.
