Multi-Robotic Arm Cooking System for Cross-Contamination Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooking meat, vegan, vegetarian, and seafood products is labor-intensive and requires human interaction, leading to variations in cooking uniformity and potential cross-contamination due to the use of multiple kitchen utensils and different cooking styles.
Innovation Solution
A multi-robotic arm cooking system comprising grills, first and second arm assemblies, and an electronic hardware controller that automatically loads prepared products onto the grills and unloads cooked products, preventing cross-contamination by using robotic arms to handle and transfer food products along a track, with sensors and actuators ensuring precise temperature control and cooking consistency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If human servers manually handle and transfer food products during cooking, then flexibility in cooking style and interaction with food is improved, but labor intensity increases and cooking uniformity decreases
Solution Approach 1:
The robotic arm system performs food handling and transfer operations autonomously without human intervention. The controller automatically controls the robotic arms to pick up food products, transfer them between cooking stations, and place them on serving trays, enabling the system to serve itself and eliminating the need for human servers in the cooking process.
Solution Approach 2:
The patent replaces the mechanical human hand and arm system with an automated robotic arm system equipped with grippers and sensors. The robotic arms can simulate human-like dexterous movements to handle various food products, while the controller provides automated decision-making and coordination, substituting the human mechanical system with an automated electromechanical system.
2Adaptability or versatility
If multiple kitchen utensils are used by human servers, then versatility in food handling is improved, but cross-contamination between pre-cooked and cooked foods increases
Solution Approach 1:
The patent divides the food handling system into separate robotic arms dedicated to specific tasks. One robotic arm is responsible for handling pre-cooked foods while another handles cooked foods, with each arm having its own grippers and tools. This segmentation ensures that utensils and handling paths are dedicated to specific food types, preventing cross-contamination while maintaining versatility through task-specific tooling.
Solution Approach 2:
The controller acts as an intermediary that coordinates the operations of multiple robotic arms, ensuring that utensils used for pre-cooked foods do not contact cooked foods. The system manages the sequence of operations and spatial arrangement to prevent cross-contamination, while the robotic grippers serve as intermediaries that can be sterilized or replaced to maintain hygiene standards.
3Ease of operation
If human servers transfer and handle food products, then direct interaction with food is improved, but variations in cooking expertise lead to non-uniform cooking results
Solution Approach 1:
The robotic arm system incorporates sensors that provide real-time feedback on food product position, temperature, and cooking status. The controller receives this feedback and automatically adjusts the cooking parameters and handling operations to maintain consistent cooking results. This closed-loop control eliminates the variations in cooking expertise by using standardized sensor-based monitoring and automated decision-making.
Solution Approach 2:
The system maintains cooking uniformity by precisely controlling and maintaining specific parameters such as cooking temperature, time, and food product positioning. The robotic arms can adjust their movements and the cooking equipment can modify heating parameters based on pre-programmed specifications, ensuring that each food product receives identical treatment regardless of human variability.
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
The system reduces labor intensity, ensures uniform cooking, and prevents cross-contamination by automating the cooking process, maintaining consistent cooking temperatures and product handling, thereby improving efficiency and food quality.
Implementation Method 1
heating a grilling surface included with at least one grill to a cooking temperature
Data Source
AI summary
A cooking system includes a grill, a first arm assembly and a second arm assembly. An electronic hardware controller is in signal communication with the at least one grill, the first arm assembly and the second arm assembly. The controller operates the first arm assembly to transfer a prepared product to the grill, and operates the second arm assembly to transfer a cooked product from the grill.
