Refrigerator having storage space formed on door body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refrigerators with door-in-door structures suffer from cold energy leakage and cross-contamination of odors between storage spaces, leading to potential bacterial spread.
Innovation Solution
A refrigerator design with independent storage spaces on the door body, featuring an inner-layer door with a storage container, air supply port, sterilization module, and air supply assembly to maintain separation and sterilization, along with optimized mounting structures for enhanced refrigeration and space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If door-in-door structure is adopted to improve space utilization, then storage space flexibility is improved, but cold energy leakage occurs when outer-layer door is opened
Solution Approach 1:
The storage space is segmented into two independent parts: the first storage space in the refrigerator body and the second storage space on the inner-layer door. They are separated by an air supply port and sterilization module, allowing the outer-layer door to be opened without causing cold energy leakage in the first storage space.
Solution Approach 2:
An air supply port and sterilization module are introduced as intermediaries between the first storage space and the second storage space. These components control airflow and prevent direct communication, eliminating cold energy leakage while maintaining space flexibility.
2Ease of operation
If storage spaces are directly connected to improve accessibility, then ease of operation is improved, but odor mixing and bacterial spread occur
Solution Approach 1:
A sterilization module is positioned at the air supply port to act as an intermediary that sterilizes air flowing between storage spaces. This prevents odor mixing and bacterial spread while maintaining controlled accessibility to both storage spaces.
Solution Approach 2:
The sterilization module creates a sterile air environment in the second storage space by sterilizing incoming air. This inertifies the atmosphere regarding harmful factors like bacteria and odors, preventing contamination while allowing access.
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
Prevents cold energy leakage and odor mixing while ensuring bacterial prevention, enhancing space flexibility and reliability of refrigeration.
Implementation Method 1
a sterilization module, disposed at the air supply port and configured to sterilize the air passing through the air supply port
Implementation Method 2
low-temperature air in the first storage space is introduced into the second storage space via the air supply port to implement refrigeration inside the second storage space
