Solution Overview
Problem
Conventional refrigerators with two doors face challenges in accurately grasping the food storage state of the inner door due to limitations in camera placement, leading to inefficient food stock management and purchase linkage services.
Innovation Solution
An artificial intelligence refrigerator with cameras mounted on the outer door, tilted to optimize the viewing angle of the inner door, coupled with sensors to detect door opening angles and processors to photograph and analyze the food storage state, providing detailed food management information on a transparent display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera is provided only on the ceiling of the refrigerator, then the structure is simple, but the food storage state of the inner door cannot be properly grasped
Solution Approach 1:
The refrigerator door system is segmented into outer door and inner door, with cameras strategically placed on the outer door to capture images of the inner door's food storage state, enabling independent monitoring of the inner door without requiring a camera inside it
Solution Approach 2:
The camera placement moves from the traditional ceiling position to the outer door position, utilizing the spatial dimension of the door assembly to achieve a viewing angle that captures the inner door's food storage state effectively
2Loss of information
If cameras are mounted on the outer door, then the food storage state of the inner door can be accurately captured, but the device complexity increases
Solution Approach 1:
The outer door is designed to serve multiple functions: it acts as both the external door structure and as the mounting platform for cameras and sensors, eliminating the need for separate internal monitoring systems and reducing overall device complexity
Solution Approach 2:
The camera system on the outer door automatically captures images of the inner door when the door is closed, and the processor automatically analyzes these images to identify food storage state, enabling self-service monitoring without additional manual intervention
3Measurement precision
If the camera is tilted to optimize the viewing angle, then the photographing accuracy of the inner door improves, but the manufacturing precision requirements increase
Solution Approach 1:
The camera is tilted at a specific angle relative to the outer door surface, transforming the geometric parameters of the camera placement to achieve optimal viewing angle for capturing the inner door's food storage state while maintaining manufacturability

AI summary
According to an embodiment of the present disclosure, an artificial intelligence refrigerator includes an inner door, an outer door having a transparent display on a front surface of the outer door, one or more cameras provided in the outer door, a sensor configured to detect an opening, a closing and an opening angle of the outer door, and at least one processor configured to determine whether the opening angle of the outer door is a preset angle when closing of the outer door is detected, photograph the inner door when the opening angle of the outer door is the preset angle, obtain a storage state of food items stored in the inner door, and display food management information on the transparent display based on the obtained storage state.
