Solution Overview
Problem
Existing personal vehicle technologies lack effective modes for ergonomic comfort and pedestrian courtesy, particularly in following user trajectories and navigating through doorways autonomously, while also failing to efficiently manage convoy behaviors and known path navigation.
Innovation Solution
A self-powered personal vehicle equipped with a mechanical drive system, sensors, and a controller that operates in pair mode to follow users with hysteresis dynamics for ergonomic comfort and pedestrian courtesy, and transitions to smart behavior mode for autonomous navigation through doorways and convoy formation, with the ability to learn and traverse known paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the vehicle follows user trajectory with hysteresis dynamics for ergonomic comfort, then user comfort and pedestrian courtesy are improved, but response latency and following precision deteriorate
Solution Approach 1:
The vehicle implements dynamic following behavior by adjusting its response characteristics based on operating conditions. The hysteresis dynamics enable the vehicle to smoothly transition between following states, adapting to user movement patterns while maintaining ergonomic comfort. This dynamic approach resolves the contradiction by making the system responsive yet comfortable rather than precisely but rigid.
2Ease of operation
If the vehicle operates in pair mode to follow user movements, then user guidance and control are improved, but autonomous navigation capability deteriorates
Solution Approach 1:
The vehicle dynamically switches between pair mode and autonomous mode based on operational context. In pair mode, it provides user guidance with hysteresis dynamics for comfort. When encountering doorways or known paths, it transitions to autonomous smart behavior mode. This dynamic mode switching resolves the contradiction by providing both user guidance and autonomous navigation at different times.
Solution Approach 2:
The system changes its operational parameters by switching between different control modes. Pair mode enables user-following behavior with specific hysteresis parameters, while smart behavior mode enables autonomous navigation with different control parameters. This parameter change approach allows the vehicle to optimize for either user guidance or autonomous navigation depending on the situation.
3Productivity
If the vehicle implements smart behavior mode for autonomous doorway passage, then navigation efficiency is improved, but system complexity and control difficulty deteriorate
Solution Approach 1:
The autonomous navigation system is segmented into distinct functional modules: sensor processing, decision-making, path planning, and execution. The smart behavior for doorway passage is separated as a specific autonomous function rather than a monolithic control system. This segmentation reduces overall system complexity by organizing functions into manageable, independent modules that can be developed and tested separately.
Solution Approach 2:
The vehicle performs preliminary actions by learning and storing known paths in advance. When encountering a known path, the vehicle retrieves pre-stored navigation data rather than processing real-time sensor information from scratch. This preliminary action approach improves navigation efficiency through doorways and complex areas while reducing the computational complexity of real-time control.
4Stability of the object's composition
If the vehicle maintains speed-dependent position for convoy behavior, then convoy coordination is improved, but maneuverability and adaptability deteriorate
Solution Approach 1:
The vehicle implements dynamic position adjustment within the convoy based on speed conditions and environmental factors. Rather than maintaining a fixed speed-dependent position, the vehicle can adapt its position dynamically while preserving convoy coordination. This dynamic approach resolves the contradiction by maintaining stable convoy structure while allowing necessary maneuverability and adaptability to different situations.
