Rotatable Delivery Robot Body for Obstacle Crossing Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unmanned delivery robots lack mechanisms to overcome obstacles while maintaining horizontal stability, which compromises the safety of delivered articles.
Innovation Solution
A mobile object design with a rotatable body and accommodation part, coupled to a drive part with wheels, allowing independent rotational motions to adjust the center of gravity for stable passage over obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the unmanned delivery robot has a mechanism for overcoming the obstacle, then the robot can climb over the obstacle, but the horizontal stability of the robot deteriorates during the process of overcoming the obstacle
Solution Approach 1:
The accommodation part is configured to be rotatable relative to the body part, allowing the center of gravity to dynamically adjust during obstacle crossing. When an obstacle is detected, the accommodation part rotates forward to shift the center of gravity, enabling the robot to climb the obstacle while maintaining stability through controlled motion rather than rigid structural changes
2Device complexity
If the unmanned delivery robot does not include a separate mechanism for overcoming the obstacle, then the structure remains simple, but the robot cannot climb over the obstacle
Solution Approach 1:
The accommodation part serves dual functions: it accommodates the article during normal operation and acts as a counterweight mechanism for overcoming obstacles. By making the accommodation part rotatable, the same structure performs multiple functions without requiring additional dedicated obstacle-crossing mechanisms, thus maintaining structural simplicity while gaining obstacle-crossing capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
