Solution Overview
Problem
Existing technologies have not effectively addressed the issue of airflow distribution and humidity control in existing aging devices, which can lead to moisture accumulation and microbial growth, resulting in spoilage and deterioration of aged objects.
Innovation Solution
A double-shell structure with a circulating fan system that directs airflow uniformly across the aging chamber, using sparse-top, dense-bottom air supply ports and a U-shaped air supply channel to enhance airflow distribution and inhibit microbial growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If objects are placed on a shelf in the aging chamber, then they are supported and positioned for aging, but the bottom sections come into contact with the shelf causing high humidity and microbial growth
Solution Approach 1:
The aging chamber bottom is segmented into multiple air supply ports distributed across the bottom surface, allowing airflow to reach beneath and around objects placed on shelves, preventing moisture accumulation at contact points
Solution Approach 2:
A circulating fan system provides forced airflow through air supply ports at the chamber bottom, creating a pneumatic flow that removes humid air from beneath objects and prevents microbial growth conditions
2Loss of energy
If airflow is not sufficient at the bottom of the aging chamber, then energy is saved, but humidity accumulates and promotes microbial growth
Solution Approach 1:
The air supply system is segmented into multiple distributed ports at the chamber bottom rather than a single centralized supply, enabling targeted airflow delivery to areas where objects contact the shelf without requiring high overall airflow
Solution Approach 2:
Airflow is concentrated locally at the bottom air supply ports where it is most needed to prevent moisture accumulation, while other areas receive ambient circulation, optimizing energy use by directing flow only where harmful humidity would accumulate
3Ease of manufacture
If air supply ports are uniformly distributed, then manufacturing is simplified, but airflow distribution uniformity is poor especially at the bottom
Solution Approach 1:
The air supply ports are arranged asymmetrically with higher density at the bottom of the aging chamber where objects contact shelves and humidity accumulates, rather than uniform distribution, creating targeted airflow where it is most needed
Solution Approach 2:
Different regions of the aging chamber bottom receive different airflow densities through strategically positioned air supply ports, with concentrated supply at areas prone to moisture accumulation rather than uniform supply throughout
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 solution ensures uniform airflow distribution, preventing spoilage and enhancing the aging process by maintaining airflow speed and humidity control, thereby improving the quality and longevity of aged objects.
Implementation Method 1
a circulating fan, configured to controllably drive airflow in the air supply channel through the air supply ports towards the aging chamber
Implementation Method 2
Inadequate airflow at the bottom can easily lead to excessive humidity, thereby promoting microbial growth

AI summary
A refrigerating and freezing device and an aging device thereof. The aging device comprises: an inner housing, the interior thereof defining an aging chamber for accommodating an object to be aged; an outer housing, disposed outside the inner housing, at least part of the circumferential side wall of the outer housing and at least part of the circumferential side wall of the inner housing being spaced apart to form an air supply channel located outside the inner housing and located inside the outer housing, and the air supply channel being communicated with the aging chamber by means of a plurality of air supply ports disposed in the circumferential side wall of the inner housing; and a circulating fan, configured to controllably drive airflow in the air supply channel to flow to the aging chamber by means of the air supply ports. The plurality of air supply ports are arranged on the circumferential side wall of the inner housing in a manner of becoming gradually dense from top to bottom. In this way, more airflow in the air supply channel can flow into the lower part of the aging chamber and be blown to the bottom of the object to be aged, thereby inhibiting growth and reproduction of microorganisms, and solving the problem that an object to be aged is prone to spoilage due to large humidity of the bottom.
