Solution Overview

Problem

Existing freezer designs consume excessive energy due to the need for separate heating devices to prevent fogging and freezing on transparent panels and doors, which complicates the structure and increases energy costs.

Innovation Solution

A freezer frame with a low-temperature part housing a light source and a heat conduction channel to the heating part, utilizing the heat from the light source to prevent fogging and freezing, and incorporating a heat insulation part with light-transmitting and heat-insulating materials to reduce energy consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a separate heating device (electric heating wire) is added to the frame to prevent fogging and freezing, then the panel fogging and door freezing problems are solved, but energy consumption increases and device complexity increases

Engineering Contradiction:
Improveprevention of panel fogging and door freezingVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent combines the lighting function and heating function into a single light source system. The light source serves dual purposes: providing illumination and generating heat to prevent fogging and freezing on transparent panels and doors. This eliminates the need for a separate heating device, thereby reducing energy consumption and device complexity while maintaining the reliability of preventing fogging and freezing.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The light source is designed to perform multiple functions simultaneously: illumination and heating. By making the light source universal, it can prevent both fogging and freezing issues that previously required a dedicated heating device, thus reducing overall energy consumption and simplifying the system structure.

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

2Reliability

If a separate heating device (electric heating wire) is added to the frame to prevent fogging and freezing, then the panel fogging and door freezing problems are solved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the lighting and heating functions into a single integrated system. The light source is positioned and designed to simultaneously provide illumination and generate heat on the transparent panels and doors, eliminating the need for separate heating wires and reducing structural complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The light source is designed as a multi-functional component that performs both illumination and heating tasks. This universality reduces the number of components needed in the system, thereby simplifying the overall device structure and reducing complexity while maintaining effective prevention of fogging and freezing.

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

3Use of energy by moving object

If a light source is provided on the low-temperature part with heat conduction channel to heating part, then additional heating devices are eliminated, but the structure becomes more complex due to heat conduction channel requirements

Engineering Contradiction:
Improveenergy consumptionVSAvoidstructure complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent integrates the heat conduction function directly into the frame structure itself. The frame serves as both the structural support and the heat conduction pathway, eliminating the need for separate heat conduction components. This merging approach reduces energy consumption by eliminating separate heating devices while minimizing structural complexity by using the existing frame for heat conduction.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The frame is designed to serve multiple functions: structural support, heat conduction, and potential mounting for the light source. By making the frame universal, it can conduct heat from the light source to the heating areas without requiring additional dedicated heat conduction components, thus reducing both energy consumption and structural complexity.

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