Solution Overview

Problem

Egg cartons occupy fixed space in refrigerators regardless of the number of eggs, leading to inefficient use of storage space.

Innovation Solution

Design of modular egg holders that can stack both horizontally and vertically using connectors, allowing for flexible configuration to optimize storage space within the refrigerator.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional egg cartons are used, then eggs are protected during transportation, but refrigerator storage space is wasted

Engineering Contradiction:
Improveegg protectionVSAvoidrefrigerator space
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The invention divides the traditional egg carton into individual modular egg holders, each capable of holding a single egg. These modular units can be used separately or combined, allowing users to occupy only the necessary refrigerator space based on the number of eggs stored, thereby eliminating wasted space while maintaining egg protection through the same dimpled cup design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention introduces vertical stacking capability through connectors that allow egg holders to be stacked vertically and horizontally. This transforms the traditional single-layer horizontal storage into multi-dimensional stacking, maximizing refrigerator space utilization while keeping each egg individually protected.

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

2Volume of stationary object

If modular egg holders with connectors are used, then refrigerator space efficiency is improved, but device complexity increases

Engineering Contradiction:
Improverefrigerator space utilizationVSAvoidconnector structure
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The connector is designed with universal functionality to work with all egg holder units in the system. Each connector can mate with corresponding connectors on any egg holder, enabling flexible configuration and stacking patterns. This standardized universal interface simplifies the overall system complexity despite the modular nature, as users don't need to learn different connection methods for different units.

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

AI summary

An egg holder is provided. The egg holder has a top portion including an upper surface and a lower surface. The upper surface may include a first vertical connector. The egg holder may further include at least one sidewall protruding from the lower surface of the top portion. The sidewall may include a second vertical connector. The second vertical connector may mate and releasably connect with the first vertical connector of a different egg holder. The present invention further includes a cup extending downward and formed to secure an egg within. A plurality of egg holders may be stacked vertically relative to one another using the first and second vertical connectors.
