Solution Overview

Problem

Current robotic systems lack the ability to replicate complex human tasks, such as cooking, with the same precision and quality as a human chef, due to limitations in sensing and execution technologies, and are not widely applicable in home or consumer settings.

Innovation Solution

A robotic kitchen system equipped with multimodal sensors, robotic arms, and hands that can replicate a chef's movements by using an electronic library of minimanipulations, allowing for real-time adjustments and quality checking, and incorporating sensors for temperature, time, and other parameters to prepare dishes identical to those made by a human chef.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If robotic systems use traditional sensing and execution technologies, then device complexity is reduced, but manufacturing precision and task replication fidelity deteriorate

Engineering Contradiction:
Improvetask replication fidelityVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent segments the cooking task into discrete minimanipulations (e.g., chopping, stirring, seasoning) that can be independently captured, stored, and executed. Each minimanipulation is broken down into sensor readings, appliance commands, and timing parameters, enabling precise replication without requiring the entire system to be overly complex. This segmentation allows the robotic system to achieve high task replication fidelity by systematically executing individual cooking steps.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs parameter changes by capturing and storing multiple variables for each minimanipulation including temperature, time, sensor readings, and appliance settings. By systematically varying and recording these parameters during the capture phase and reproducing them during execution, the system achieves high manufacturing precision in task replication. The electronic library stores these parameter sets, allowing the robotic system to precisely reproduce cooking conditions without requiring complex real-time adjustments.

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If robotic systems capture and reproduce chef movements with high fidelity, then task replication quality improves, but ease of operation deteriorates

Engineering Contradiction:
Improveculinary task replication qualityVSAvoidsystem setup complexity
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent implements self-service by enabling the robotic system to automatically capture chef movements and cooking processes during a demonstration phase without requiring manual programming. The system autonomously records sensor data, appliance commands, and timing information, then stores this information in an electronic library for later execution. This eliminates the need for complex manual setup and programming, significantly improving ease of operation while maintaining high task replication quality.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent applies preliminary action by having the system capture and store all necessary cooking information during an initial demonstration phase before actual execution. The electronic library pre-stores minimanipulations with all their parameters (temperature, time, sensor readings, commands), so that when it comes time to execute a recipe, the system simply retrieves and follows the pre-captured instructions. This preliminary capture process simplifies operation by eliminating the need for complex real-time decision-making or programming during cooking execution.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If robotic systems use comprehensive sensors and electronic libraries, then task execution precision improves, but loss of time in system setup and calibration increases

Engineering Contradiction:
Improvecooking parameter measurement accuracyVSAvoidsystem setup time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by capturing all cooking parameters, sensor readings, and appliance commands during an initial demonstration phase and storing them in an electronic library. This pre-capture process eliminates the need for time-consuming setup and calibration during actual cooking execution. The system simply retrieves pre-validated parameter sets from the library, maintaining high measurement precision while minimizing setup time.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by creating digital replicas of chef cooking processes through the electronic library. Instead of requiring physical setup and calibration of sensors and appliances for each cooking task, the system copies the entire cooking process information (sensor readings, temperature profiles, timing, commands) into a digital format that can be instantly retrieved and executed. This copying approach maintains measurement precision by preserving exact parameter values while eliminating repetitive setup time.

Inventive Principle:
Principle #26Copying

4Manufacturing precision

If robotic systems are designed for high-precision culinary task execution, then manufacturing precision improves, but ease of manufacture deteriorates

Engineering Contradiction:
Improvecooking task execution precisionVSAvoidsystem implementation difficulty
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent applies universality by designing a standardized electronic library structure and minimanipulation framework that can capture and execute various types of cooking tasks using the same system architecture. The same sensor suite, appliance interfaces, and control algorithms can handle different cuisines, cooking methods, and recipes by simply loading different minimanipulation sets from the library. This multi-functionality approach enables high cooking task execution precision while simplifying manufacture, as the system doesn't require custom design for each specific cooking task.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent segments cooking tasks into standardized minimanipulations with defined parameters and execution protocols. This segmentation allows the system to achieve high manufacturing precision by systematically executing individual cooking steps with controlled variables, while also simplifying manufacture by breaking down complex cooking processes into manageable, reusable components. The modular minimanipulation structure makes the system easier to implement and maintain compared to attempting to execute entire cooking processes as monolithic operations.

Inventive Principle:
Principle #1Segmentation
