Solution Overview

Problem

Conventional smart refrigerators face issues with camera collision, inadequate installation, limited shooting angle, and dew formation due to improper placement of cameras in refrigerators, affecting service life and user experience.

Innovation Solution

The camera is mounted on a vertical beam within the refrigerator, which rotates with the door, preventing collision and allowing a wider shooting angle, and a dew removal heating device is integrated to prevent moisture buildup, ensuring clear images and improved aesthetics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the camera is installed on the front side of the upper wall of the refrigerator inner container, then the camera is easily accessible and visible to users, but the camera is prone to collision and damage by articles being taken and placed

Engineering Contradiction:
Improvecamera accessibilityVSAvoidcamera collision resistance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The camera is moved from the front wall (2D surface mounting) to the door assembly (3D spatial relocation), specifically mounted on the inner surface of the door body or door rack. This dimensional change relocates the camera to a position that is both accessible during door operation and protected from direct collision with stored articles.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The door assembly acts as an intermediary structure that houses the camera, separating it from direct exposure to articles in the storage chamber. The camera is mounted on the door or door rack, which serves as a protective intermediary between the camera and the articles being handled by users.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the camera is installed in a low-temperature and high-humidity environment inside the refrigerator, then the camera can monitor the storage compartment, but dew formation occurs on the camera

Engineering Contradiction:
Improvestorage monitoring capabilityVSAvoiddew formation on camera
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The camera is extracted from the cold storage chamber environment and relocated to the door assembly, which is partially exposed to ambient air. This extraction removes the camera from the harmful low-temperature, high-humidity environment that causes dew formation, while the camera still maintains monitoring capability through strategic positioning.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The environmental parameters (temperature and humidity) experienced by the camera are changed by relocating it from the cold storage chamber to the door assembly. The door assembly experiences more moderate temperature and humidity conditions, preventing dew formation while maintaining the camera's ability to capture images of the storage compartment.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the camera is mounted on the door rack, then the camera is protected from collision, but the camera housing support protrudes from the door rack surface

Engineering Contradiction:
Improvecamera collision protectionVSAvoiddoor rack surface flushness
Core Design Contradiction:
ReliabilityVSShape

Solution Approach 1:

The door rack serves multiple functions: it provides structural support for the door, offers a mounting surface for the camera, and acts as a protective barrier. By utilizing the door rack's existing structure and space, the camera can be mounted in a way that maintains surface flushness while leveraging the door rack's protective function.

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

Solution Approach 2:

The camera housing is nested within or integrated into the door rack structure. The camera mount is designed to fit within the door rack's available space, with the outer surface of the camera housing aligned flush with the door rack surface, creating a nested appearance that maintains surface continuity.

Inventive Principle:
Principle #7Nested doll (Nesting)
