Self-Driving Luggage Side-Follow Navigation for Obstacle Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current self-driving luggage systems are limited in maneuverability, especially in crowded areas, as they follow from behind and lack effective obstacle avoidance capabilities.
Innovation Solution
A smart self-driving system equipped with motorized wheel assemblies, cameras, and proximity sensors that allow it to autonomously follow a user on the side while detecting obstacles, transitioning between side and rear follow positions to navigate through crowded spaces effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the luggage follows from behind the user, then it is simple to implement, but it lacks maneuverability to avoid obstacles especially in crowded places
Solution Approach 1:
The luggage dynamically transitions between different follow positions (side follow and rear follow) based on real-time obstacle detection and user position, rather than maintaining a fixed position. This dynamic adaptability resolves the contradiction by allowing the system to switch configurations to maintain maneuverability while managing complexity through context-based position selection.
Solution Approach 2:
The system adds the spatial dimension of lateral positioning by implementing side follow capability in addition to traditional rear following. This dimensional expansion allows the luggage to navigate around obstacles by moving to the user's side, significantly improving maneuverability in crowded environments while maintaining a manageable system architecture.
2Ease of operation
If the luggage stays in a fixed follow position, then it simplifies control, but it cannot effectively navigate through crowded spaces
Solution Approach 1:
The control system dynamically adjusts the luggage's follow position between side and rear configurations based on detected obstacles and user position, rather than maintaining a static position. This dynamic control approach maintains relative simplicity while significantly improving navigation capability in crowded spaces.
Solution Approach 2:
The luggage autonomously determines when to switch between side follow and rear follow positions based on its own sensor inputs (obstacle detection, user position tracking), eliminating the need for complex external control inputs from the user. This self-service approach maintains ease of operation while enhancing navigation adaptability.
3Reliability
If the luggage follows closely behind the user, then it maintains good visibility of the user, but it has limited ability to detect obstacles in front
Solution Approach 1:
By transitioning to a side follow position, the luggage changes its spatial relationship to the user, positioning itself laterally where it can simultaneously maintain user visibility and improve forward obstacle detection. This dimensional repositioning resolves the contradiction between tracking reliability and obstacle detection capability.
Solution Approach 2:
The side follow position acts as an intermediary configuration that balances both user tracking and obstacle detection requirements. From this intermediate position, the luggage can monitor the user while having better line-of-sight to potential obstacles in the user's path, eliminating the need to choose between the two competing requirements.
