Solution Overview
Problem
Conventional refrigerator deodorizing devices are inefficient due to their placement, which reduces air circulation and storage space, and are aesthetically unappealing as they protrude and are exposed when the door is opened.
Innovation Solution
A refrigerator design with a deodorizing device positioned on the upper surface of the storage space, adjacent to the cold air discharge port, utilizing an upper duct surrounded by insulating material and a deodorizing filter with a sterilization LED, enhancing air circulation and deodorization efficiency while minimizing visual exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the deodorizing device is placed on the rear wall of the refrigerator inside, then it is directly exposed when the door is opened improving accessibility, but the outer appearance is degraded and storage space is reduced
Solution Approach 1:
The deodorizing device is relocated from the rear wall to the upper surface of the storage space, changing its spatial dimension. This repositioning allows the device to be accessible while not protruding forward to compromise appearance or storage capacity.
Solution Approach 2:
The deodorizing device is integrated into the upper duct structure, with the upper discharge port formed in the duct itself. This nesting approach allows the deodorizing function to be embedded within the existing air circulation system without adding external protrusions.
2Shape
If the deodorizing device is placed above the rear of the storage space, then it is hidden from view improving appearance, but deodorization efficiency is reduced due to poor air circulation
Solution Approach 1:
Cold air is discharged from the upper discharge port before reaching the deodorizing device, creating a pre-established airflow pattern that directs air efficiently through the deodorizing filter. This preliminary air movement ensures optimal deodorization performance.
Solution Approach 2:
The upper duct serves multiple functions: it guides cold air from the evaporator, provides structural support for the deodorizing device, and creates the airflow path necessary for effective deodorization. This multi-functionality maintains efficiency while improving appearance.
3Ease of operation
If the deodorizing device protrudes forward in the storage space, then it is accessible when the door is opened, but storage space is lost
Solution Approach 1:
The deodorizing device is positioned on the upper surface rather than protruding forward horizontally. This dimensional change maintains accessibility while preserving the horizontal storage space capacity of the refrigerator.
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
Improves deodorization performance by positioning the deodorizing device near the cold air discharge point, ensuring effective air circulation and user satisfaction, while maintaining a clean and aesthetically pleasing appearance by reducing direct exposure and maximizing storage space.
Implementation Method 1
cooling the inside of the storage space using cold air generated through heat exchange with the refrigerant circulating in the refrigeration cycle
Implementation Method 2
an insulating material which is filled between the outer case and the inner case
