Cooling device having at least two storage compartments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling devices with multiple compartments require thick insulation walls between compartments to maintain temperature differences, leading to increased production costs and reduced inner volumes.
Innovation Solution
A cooling device design featuring a door that encloses both compartments with integrated gaskets and bosses, reducing the need for thick insulation walls between compartments, while using pull-out brackets for easier door operation and decorative panels for assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If separate doors are provided for each storage compartment, then thermal insulation between compartments is improved, but the insulation wall thickness must be increased
Solution Approach 1:
The patent combines multiple door functions into a single door structure that serves multiple storage compartments simultaneously. This single door includes integrated gaskets and bosses that provide thermal insulation for multiple compartments, eliminating the need for separate doors for each compartment and reducing the overall insulation wall thickness required.
Solution Approach 2:
The single door structure is designed to perform multiple functions: it closes multiple storage compartments, provides thermal insulation for each compartment through integrated gaskets, and maintains structural integrity through bosses. This multi-functional design replaces what would traditionally require multiple separate door assemblies.
2Loss of energy
If thick insulation walls are provided between storage compartments, then thermal insulation is improved, but production costs increase
Solution Approach 1:
The patent merges the insulation function into the door assembly itself through integrated gaskets and bosses, rather than requiring thick insulation walls between compartments. This reduces the quantity of insulation material needed and simplifies the manufacturing process by consolidating insulation components.
Solution Approach 2:
The patent uses flexible gasket materials in the door assembly to provide effective thermal insulation. These thin, flexible insulation elements are more material-efficient than thick rigid insulation walls, reducing both material costs and manufacturing complexity while maintaining effective thermal barriers.
3Loss of energy
If separate doors with individual gaskets are used for each compartment, then thermal insulation is improved, but device complexity increases
Solution Approach 1:
The patent consolidates multiple door assemblies into a single integrated door structure with unified gasket and boss components. This reduces the total number of parts, simplifies assembly procedures, and decreases device complexity while maintaining comprehensive thermal insulation coverage for multiple storage compartments.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design increases storage compartment volumes, reduces production costs by minimizing insulation material usage, and enhances thermal insulation, allowing for varied compartment shapes and sizes.
Implementation Method 1
the door has at least one gasket in order to rest at the flank part in a manner encircling the storage compartment. Thus, thermal insulation is provided between the door and the body.
Implementation Method 2
This design increases storage compartment volumes, reduces production costs by minimizing insulation material usage, and enhances thermal insulation

AI summary
A cooling device includes a body and at least two storage compartments having at least one insulation wall therebetween. At least one door is associated with a flank part of the body facing the door. Accordingly, the door is configured in such a manner as to close the inlet of the at least two storage compartments.
