Solution Overview

Problem

Refrigerators do not allow users to view their contents without opening the door, leading to increased energy consumption and potential food waste due to unawareness of available items, as existing solutions are limited in viewing capabilities and require complex camera movements.

Innovation Solution

Integration of internal content cameras and light sources within the refrigerator, controlled by a controller to capture images of different portions of the compartment with varying illuminations, enabling remote viewing of the contents through a user device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If a single camera is used to view refrigerator contents, then device complexity is reduced, but the area of compartment that can be viewed is limited

Engineering Contradiction:
Improveviewable compartment areaVSAvoidcamera system complexity
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The refrigerator compartment is divided into multiple viewing zones, with each camera responsible for capturing a specific portion. Two cameras are positioned to capture different portions of the compartment, allowing the entire area to be viewed without increasing mechanical complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The solution transitions from a single viewpoint to multiple viewpoints by positioning cameras at different locations within the compartment. This spatial distribution of cameras enables comprehensive coverage of the compartment area without requiring complex moving mechanisms.

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

2Measurement precision

If uniform illumination is provided throughout the compartment, then lighting complexity is reduced, but image quality varies across different portions

Engineering Contradiction:
Improveimage qualityVSAvoidillumination system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Different portions of the compartment receive customized illumination tailored to their specific lighting needs. The controller provides different illuminations for respective camera zones, ensuring optimal image quality in each area without requiring a complex unified lighting system.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The illumination system is made dynamic and adaptive, with the controller adjusting lighting conditions based on which portion of the compartment is being viewed. This allows image quality to be optimized for different zones without permanently complexifying the lighting infrastructure.

Inventive Principle:
Principle #15Dynamics

3Loss of information

If the door remains closed to conserve energy, then energy consumption is reduced, but users cannot view the contents

Engineering Contradiction:
Improvecontent visibilityVSAvoidenergy consumption
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

Instead of requiring users to open the door to view contents, the system creates visual copies (images) of the compartment interior using cameras. These images are transmitted to user devices, allowing remote viewing without physical door opening and thus without energy loss from temperature fluctuations.

Inventive Principle:
Principle #26Copying
