Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ovens lack the ability to accurately determine the volume and type of cooking materials within the oven, limiting their functionality in providing tailored cooking processes.
Innovation Solution
An oven equipped with a camera, communication interface, and processors that capture images of cooking materials, display a guide UI for capturing, transmit images to a server for volume information, and determine a cooking process based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera is added to capture images of cooking materials, then measurement precision of cooking material volume and type is improved, but device complexity increases
Solution Approach 1:
The patent introduces a server as an intermediary component that receives images from the oven's camera, processes them to determine cooking material volume and type, and returns results to the oven controller. This externalizes the complex image processing functionality, allowing the oven to achieve precise measurement capabilities without incorporating complex processing hardware directly into the oven system.
2Productivity
If image processing and volume determination functions are integrated into the oven, then productivity of cooking process determination is improved, but device complexity increases
Solution Approach 1:
The patent extracts the complex image processing and volume determination functions from the oven system and relocates them to an external server. The oven controller only handles image acquisition and result application, while the computationally intensive processing tasks are performed externally, maintaining high productivity without increasing oven system complexity.
3Measurement precision
If multiple image sets are captured and processed through server communication, then measurement precision of cooking material properties is improved, but loss of time in the cooking preparation process increases
Solution Approach 1:
The system performs preliminary actions by capturing multiple image sets at different stages (before cooking, during cooking) and preparing them for processing. The guide UI is displayed in advance to guide users through the capture process, ensuring all necessary images are collected before the actual cooking begins, thus minimizing time loss during the cooking process itself.

AI summary
An oven and a method for controlling same where the oven comprises: a door; a camera; a communication interface; and one or more processors. The one or more processors acquire, by of a camera, a first image of at least one food item, displays, on an area of the door on the basis of the acquired first image, a guide UI for the at least one food item, transmits the first image to a server device through the communication interface, receives volume information on the at least one food item from the server device, and determines a cooking process for the at least one food item based on the volume information. At this time, the volume information on the at least one food item is obtained on the basis of the first image and a second image acquired by a user terminal device according to the UI.
