Pneumatic Dish Adsorber with Air Ejection for Stable Robot Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robots face difficulties in stably lifting dishes due to foreign objects or water on their surfaces, leading to potential slipping or unstable adsorption, which can result in the dishes being detached during movement or washing processes.
Innovation Solution
A robot equipped with an air ejecting method to remove foreign objects and water from dish surfaces using a combination of suction and ejection nozzles, controlled by a force sensor and vision sensor to ensure stable adsorption and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot uses an air suction device to adsorb dishes, then the dishes can be lifted, but the adsorption becomes unstable due to foreign objects or water on the dish surface
Solution Approach 1:
The robot performs air ejection to remove foreign objects and water from the dish surface before the air suction device adsorbs the dish. This preliminary cleaning action ensures that the subsequent adsorption process is not interfered with by contaminants on the dish surface, thereby improving adsorption stability.
Solution Approach 2:
The robot uses the air ejection device to extract and remove foreign objects and water from the dish surface. By taking out these harmful factors before adsorption, the system ensures that only the clean dish surface remains for stable air suction adsorption.
2Ease of operation
If the robot grabs and lifts dishes directly, then the lifting operation is simple, but the dishes may slip due to foreign objects or water on the surface
Solution Approach 1:
The robot replaces direct mechanical grabbing with pneumatic adsorption using the air suction device. The air suction creates a vacuum that adsorbs the dish to the adsorber, providing reliable grip without the complexity of mechanical grippers. The pneumatic system maintains stable adsorption even when dishes are wet or have foreign objects, as the air ejection pre-cleans the surface.
3Reliability
If the robot uses a complex air ejection system to remove foreign objects, then adsorption stability improves, but the device complexity increases
Solution Approach 1:
The robot combines the air ejection device and air suction device into a single integrated adsorber assembly. Both devices share the same structural framework and control system, allowing the robot to perform cleaning and adsorption functions simultaneously or sequentially without requiring separate complex systems. This merging reduces overall device complexity while maintaining adsorption stability.
