Solution Overview

Problem

The existing refrigeration appliances with trough-like depressions on their bases face challenges in accessing and utilizing the lower area due to obstructions from refrigerated goods carriers or pull-out drawers, leading to inefficient and unsafe use of the space.

Innovation Solution

The solution involves connecting containers via a joint in the refrigerator, allowing them to be easily removed together, with one container tiltable for lifting while the other is pulled along, and incorporating a cover plate and inclined embankment for improved access, along with lockable trays and handles for secure handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a refrigerated goods carrier is arranged above the depression, then storage capacity is improved, but access to the depression is blocked

Engineering Contradiction:
Improvestorage capacityVSAvoidaccess to depression
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The refrigerated goods carrier is divided into a movable front section and a fixed rear section. The movable front section can be pulled forward to clear the path to the depression, allowing access while maintaining storage capacity when pushed back into position.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The front section of the refrigerated goods carrier is made movable rather than fixed, allowing it to be dynamically repositioned. When access to the depression is needed, the front section can be pulled forward; when storage is the priority, it can be pushed back into place.

Inventive Principle:
Principle #15Dynamics

2Loss of energy

If the depression is covered by a cover plate, then thermal insulation is improved, but access to the depression is restricted

Engineering Contradiction:
Improvethermal insulationVSAvoidaccess to depression
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The cover plate is made movable rather than fixed, allowing it to be opened when access to the depression is needed and closed when thermal insulation is the priority. This dynamic design balances energy efficiency with operational accessibility.

Inventive Principle:
Principle #15Dynamics
