Driving Robot Air Suspension Structure for Uneven Surface Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Driving robots experience instability and shaky posture when traveling on uneven surfaces due to varying forces applied to their casters, leading to potential changes in driving direction or stoppage.
Innovation Solution
The driving robot is equipped with a suspension system featuring air suspensions for each caster, connected through interconnected air tubes, allowing for synchronized pressure adjustments to maintain stability by minimizing rolling and pitching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If independent air suspensions are used for each caster, then each caster can be adjusted independently, but the system complexity increases
Solution Approach 1:
The patent combines multiple air suspension systems into a single integrated system where casters are connected through common air chambers and flow paths. This allows independent adjustment of each caster while sharing pneumatic components, thereby reducing overall system complexity while maintaining adaptability.
Solution Approach 2:
The air suspension system is designed with universal components that serve multiple functions. The same air chambers and flow path structures are used across different casters, allowing a single system design to handle various adjustment needs of multiple casters simultaneously.
2Adaptability or versatility
If multiple separate flow paths are used for air suspensions, then each caster can be controlled independently, but the response time for vibration reduction increases
Solution Approach 1:
The patent merges multiple flow paths into a single integrated flow path that connects all air suspensions. This allows pressure changes to be transmitted simultaneously to all casters through the common flow path, significantly reducing the response time for vibration reduction while still allowing individual caster adjustment through selective valve control.
3Stability of the object's composition
If rigid suspension is used, then structural stability is maintained, but the robot cannot adapt to uneven surfaces
Solution Approach 1:
The patent implements a dynamic suspension system using pneumatic air chambers that can adjust their stiffness and damping characteristics in real-time. The air pressure can be dynamically changed to adapt to different surface conditions, providing both stability on flat surfaces and compliance on uneven terrain.
Solution Approach 2:
The suspension system changes its physical parameters (air pressure, volume) dynamically to adapt to different operating conditions. By adjusting the air pressure in the chambers, the system can transition between rigid and compliant states, maintaining structural stability when needed and surface adaptation when needed.
