Solution Overview

Problem

Existing refrigerator systems do not effectively provide information about objects stored inside without opening the door, especially for obscured or hard-to-identify items, and lack efficient methods for tracking container contents and expiration dates.

Innovation Solution

A method and system using a camera and display unit in the refrigerator to capture images of stored objects, display substitute images upon user input, and provide detailed information, including expiration dates and container contents, through augmented reality techniques, allowing users to identify objects and track container positions without opening the door.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If users open the refrigerator door to identify stored items, then they can see the contents clearly, but energy loss increases and storage temperature stability deteriorates

Engineering Contradiction:
Improvevisibility of stored itemsVSAvoidenergy loss from door opening
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent uses a camera to capture images of stored items and displays them on a display unit mounted on the refrigerator door or externally. This creates a visual copy of the interior contents, allowing users to identify items without opening the door, thereby preventing energy loss and temperature fluctuations that would occur with frequent door openings.

Inventive Principle:
Principle #26Copying

2Loss of information

If users open the refrigerator door to locate specific items, then they can identify obscured objects, but time loss increases due to searching

Engineering Contradiction:
Improveidentification of obscured itemsVSAvoidtime to locate items
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The camera captures real-time or periodic images of the refrigerator interior and displays them on the display unit. Users can view the complete contents including obscured items without physically opening the door and searching, significantly reducing the time required to locate specific items.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system performs preliminary action by continuously capturing and displaying images of the refrigerator contents before the user needs to access them. This allows users to plan their retrieval operations in advance, opening the door only when necessary and knowing exactly what to look for, thereby reducing both time loss and energy consumption.

Inventive Principle:
Principle #10Preliminary action

3Loss of information

If the refrigerator displays detailed information about all stored items, then information completeness improves, but device complexity increases

Engineering Contradiction:
Improvecompleteness of item informationVSAvoidsystem complexity for information processing
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system displays information selectively rather than showing all possible data about every item. The display unit presents relevant information such as item images, expiration dates, and basic identification, while omitting less critical details. This partial action approach provides sufficient information for most user needs without requiring complex processing and storage systems.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A method of providing information about an object in a refrigerator is provided. The method includes: obtaining, using a camera, an image of a plurality of objects stored in the refrigerator; displaying the image on a display of the refrigerator; receiving a first user input indicating a first object from among the plurality of objects included in the image; and displaying a substitute image of the first object on the display based on the first user input.
