Showcase with two-story structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional refrigeration showcases lack separate temperature control between upper and lower storage chambers, leading to inefficient cold air circulation and ice formation, which complicates cooling control and reduces storage capacity.
Innovation Solution
A two-story showcase structure with separate upper and lower storage chambers, featuring cold air introduction and exhaust holes, suction fans, and fan cases for gentle air circulation, along with drawers for easy access and ice cream storage container frames for uniform cold air distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional refrigeration showcases use a single storage chamber, then the structure is simple, but the temperature distribution is uniform and cannot accommodate foods with different storage requirements
Solution Approach 1:
The storage chamber is divided into an upper story storage chamber and a lower story storage chamber, allowing different temperature distributions in each chamber. The upper chamber stores foods requiring higher temperatures while the lower chamber stores foods requiring lower temperatures, thus accommodating diverse storage requirements without excessive complexity
Solution Approach 2:
The patent introduces a vertical dimension by stacking storage chambers at different heights. The upper story storage chamber is positioned above the lower story storage chamber, creating a three-dimensional temperature distribution system that accommodates different storage needs along the vertical axis
2Reliability
If conventional refrigeration showcases lack cold air circulation structure, then the structure is simple, but cold air accumulates at the bottom causing ice formation
Solution Approach 1:
Cold air introduction holes are positioned at different locations for the upper and lower storage chambers. The lower story storage chamber has cold air introduction holes at its bottom, while the upper story storage chamber has cold air introduction holes at its front, creating localized cold air supply that prevents accumulation and ice formation
Solution Approach 2:
The patent introduces dynamic air circulation through fans that actively move cold air from the refrigeration chamber through ducts into the storage chambers. This dynamic system replaces static cold air accumulation with continuous circulation, preventing ice formation while maintaining reliable cooling
3Productivity
If ice forms in the storage chambers, then cooling control becomes difficult, but the storage capacity decreases
Solution Approach 1:
Cold air is introduced in advance to the bottom and front areas of the storage chambers where ice formation is most likely to occur. By proactively supplying cold air to these critical zones, the system prevents ice formation before it can reduce storage capacity or complicate cooling control
Solution Approach 2:
The continuous circulation system creates a feedback mechanism where cold air is constantly moved through the storage chambers, detecting and correcting temperature imbalances before they lead to ice formation. This maintains optimal cooling control and preserves storage capacity

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 configuration allows for distinct temperature control between storage levels, preventing ice formation and ensuring efficient cooling, thus enhancing storage capacity and usability by maintaining consistent refrigeration temperatures and reducing the need for frequent ice removal.
Implementation Method 1
a plurality of suction fans for moving the cold air from the refrigeration chamber into the upper story and lower story through ducts
Implementation Method 2
upper story and lower story each having cold air introduction holes

AI summary
A showcase with a two-story structure includes a body having an upper story storage chamber with a top opening formed on top thereof and first cold air introduction holes formed on the side surfaces thereof and a lower story storage chamber separately disposed adjacent to the underside of the upper story storage chamber and with a front opening formed on front thereof and second cold air introduction holes formed on the side surfaces thereof; upper doors for opening and closing the top opening of the upper story storage chamber; and drawers for slidingly opening and closing the front opening of the lower story storage chamber.
