Solution Overview

Problem

Food service appliances require time-consuming and error-prone manual input for selecting and processing food products, often using expensive graphical input panels.

Innovation Solution

A food preparation appliance equipped with a food recognition system, including sensors and a controller, automatically identifies and processes food products by analyzing pre-processing, in-process, and post-processing data to set optimal operating parameters such as temperature, speed, and humidity, allowing for simultaneous processing of multiple products with different parameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual input is used to select and process food products, then the appliance can process food items, but the process becomes time-consuming and error-prone

Engineering Contradiction:
Improveinput accuracyVSAvoidprocessing time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system uses sensors to automatically detect and identify food products on the conveyor belt, allowing the appliance to self-determine processing parameters without manual input. The controller receives sensor data, automatically selects the appropriate food item from a database, and configures processing settings autonomously.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical input (buttons, touchscreens) with an automated optical sensing system. Sensors capture images of food products, and the system uses image processing and pattern recognition to automatically identify items and trigger appropriate processing sequences.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If graphical input panels are used for food selection, then user interface functionality is provided, but the cost of the appliance increases

Engineering Contradiction:
Improveuser interface capabilityVSAvoidappliance cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The system eliminates the need for user interaction with graphical input panels by implementing automatic food identification through sensors. The appliance independently detects food items, retrieves processing parameters from its database, and executes the appropriate processing sequence without requiring expensive user interface components.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent removes the graphical input panel component entirely from the system, extracting only the essential function of food selection and processing control. This is achieved by implementing sensor-based automatic detection that replaces the need for manual input interfaces.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If multiple food products are processed simultaneously, then productivity increases, but tracking and controlling each product becomes more complex

Engineering Contradiction:
Improveprocessing throughputVSAvoidtracking system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system processes multiple food products simultaneously by dividing the conveyor belt into discrete zones, each with its own sensor array. The controller segments the processing task by individually tracking each product's position and characteristics, applying appropriate processing parameters to each item independently while maintaining overall system coordination.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements continuous feedback loops where sensors monitor each food product's position, type, and processing state in real-time. The controller receives this feedback data and dynamically adjusts processing parameters for each individual product, enabling simultaneous processing of multiple items with precise control over each one's treatment.

Inventive Principle:
Principle #23Feedback

AI summary

A food preparation appliance includes a housing, a conveyor, a thermal element, a first sensor, a second sensor, and a third sensor. The housing defines an inlet, an outlet, and a processing zone between the inlet and the outlet. The conveyor is configured to move a food product from the inlet, through the processing zone, and to the outlet. The thermal element is positioned within the processing zone. The first sensor is positioned proximate the inlet of the housing and along a lateral side of the conveyor or along a first cantilever arm extending laterally across the conveyor. The second sensor is positioned within the processing zone. The third sensor is positioned proximate the outlet of the housing and along a lateral side of the conveyor or along a second cantilever arm extending laterally across the conveyor.
