Solution Overview

Problem

Existing refrigerator and freezer cameras are cumbersome, difficult to maintain, and obstructive due to their rectangular shape and fixed installation, requiring professional service for replacement and causing space and adjustment issues.

Innovation Solution

A cylindrical camera with an upright arrangement, detachable design, and wireless connectivity, allowing easy placement among refrigerated goods, avoiding unnecessary adjustments and obstacles, with a stable and adjustable viewing angle.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rectangular camera with fixed installation is used, then the camera can be securely mounted in designated positions, but it requires professional service for replacement and causes space obstruction in the refrigerator

Engineering Contradiction:
Improvesecure mountingVSAvoiduser-friendly maintenance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The camera is designed as a separable component that can be easily detached from the refrigerator interior. The mounting system is divided into a camera unit and a mounting structure, allowing the camera to be removed and reinstalled by users without requiring professional service technicians.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of making the camera permanently fixed for security, the invention inverts the approach by designing a removable mounting system that achieves secure positioning during use while enabling easy removal for maintenance. The mounting arm allows the camera to be temporarily attached and detached as needed.

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If a spherical camera is permanently attached, then the camera is securely fixed, but it is difficult to remove and requires readjustment by service technicians

Engineering Contradiction:
Improvesecure fixationVSAvoidcamera replacement
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The camera system is segmented into a camera unit and a separate mounting structure with a mounting arm. This segmentation allows the camera to be easily detached from the mounting arm by users for replacement or maintenance, eliminating the need for service technician intervention while maintaining secure positioning during operation.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If cameras are mounted on surfaces not intended for storing goods, then the camera can be positioned for imaging, but it obstructs space and may cause collisions with refrigerated goods

Engineering Contradiction:
Improveviewing angleVSAvoidusable storage space
Core Design Contradiction:
Measurement precisionVSVolume of moving object

Solution Approach 1:

The camera is mounted on the interior surface of the refrigerator door rather than on shelves or walls where goods are stored. This utilizes the door's third dimension (the door panel space) for camera placement, keeping the camera positioned for optimal imaging while leaving all storage surfaces completely available for refrigerated goods without obstruction.

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

4Ease of operation

If the camera is made removable for easy maintenance, then user-friendliness improves, but the mounting structure becomes more complex

Engineering Contradiction:
Improvemaintenance accessibilityVSAvoidmounting structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mounting system is segmented into a simple mounting arm and a camera unit with a corresponding mounting structure. This segmentation enables easy removal and reinstallation of the camera by users while keeping each component individually simple in design, avoiding the need for complex integrated mounting mechanisms.

Inventive Principle:
Principle #1Segmentation
