Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigerators with wood material cabinet covers face issues with resistance to stains, scratches, chemical damage, heat, and deformation, especially when external objects are placed on the rear surface, affecting their efficiency and aesthetics.
Innovation Solution
A refrigerator design featuring a cabinet cover and front panel made of stone material, coupled using a foaming liquid in a foaming space between the stone front panel and door liner, with insulating material and guide grooves for secure attachment, enhancing durability and aesthetics while preventing deformation and efficiency loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a wood material cabinet cover is used, then the aesthetic design is achieved, but the resistance to stains, scratches, chemical damage, and heat is not high
Solution Approach 1:
The patent applies composite materials by combining a stone material front panel with a door liner to create a cabinet cover that maintains aesthetic design while significantly improving resistance to stains, scratches, chemical damage, and heat. The stone material serves as the outer decorative layer while the door liner provides structural support and additional protection.
2Reliability
If a stone material front panel is used, then the durability and resistance to damage are improved, but the processing difficulty increases
Solution Approach 1:
The patent segments the cabinet cover into a stone material front panel and a separate door liner, allowing each component to be manufactured and processed independently. This segmentation enables the use of difficult-to-process stone material for the visible front panel while the door liner can be easily manufactured and later assembled through coupling.
3Adaptability or versatility
If objects are disposed on the rear surface of the refrigerator, then the space utilization is improved, but the efficiency of the refrigerator is deteriorated
Solution Approach 1:
The patent introduces a rear cover as an intermediary component between objects disposed on the rear surface and the refrigerator's heat dissipation system. This rear cover is designed with heat dissipation holes that allow thermal energy to pass through, enabling objects to be placed on the rear surface while maintaining proper heat dissipation and preventing efficiency deterioration.
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
The stone material provides improved durability and resistance to stains, scratches, and heat, maintaining a neat appearance and preventing insulating material leakage, while allowing for versatile design and efficient operation even with objects on the rear surface.
Implementation Method 1
a foaming liquid injected into a foaming space formed by the front panel and the door liner
Implementation Method 2
an insulating material provided in the foaming space
