Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current serving robots face challenges in maintaining the horizontality of the loading part during acceleration, deceleration, and movement on slopes, which can lead to instability and spills when carrying food items, and in efficiently interacting with users to receive orders and serve food.
Innovation Solution
A serving robot with a main body, an arm rotatably connected to both the main body and a loading part, and a processor that controls the arm and loading part to maintain horizontality based on acceleration, deceleration, and tilt information, using sensors and motors to adjust the position and orientation of the loading part, including a tray and display, to ensure stable food delivery and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the arm is rotated during acceleration or deceleration, then the robot can maintain horizontality of the loading part, but the control complexity increases
Solution Approach 1:
The processor continuously receives acceleration and tilt information from sensors, dynamically adjusts arm rotation and loading part orientation in real-time based on detected motion states, creating a closed-loop control system that maintains horizontality while adapting to changing conditions
Solution Approach 2:
The system transitions from static positioning to dynamic adjustment by rotating the arm and loading part based on real-time acceleration and tilt data, allowing the robot to adapt its configuration during movement to maintain stability
2Productivity
If the robot moves quickly to serve food, then productivity increases, but food stability decreases due to acceleration and deceleration effects
Solution Approach 1:
The processor proactively rotates the arm and loading part in opposition to detected acceleration and deceleration forces before food instability occurs, preventing spills and maintaining food stability during rapid movement
Solution Approach 2:
The system performs preliminary adjustments to arm and loading part orientation based on predicted motion dynamics, preparing the system in advance for acceleration or deceleration events to maintain food stability
3Ease of operation
If the robot interacts with users to receive orders, then service quality improves, but the time required for food delivery increases
Solution Approach 1:
The robot performs interactions at periodic intervals or at predetermined locations along its delivery path, allowing it to communicate with users without continuously stopping, thereby maintaining service quality while minimizing delivery time
