Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Household cooling devices, such as refrigerators, often fail to provide rapid and efficient cooling for bottles without risking overcooling or freezing, which can lead to expansion and potential explosion of liquids.
Innovation Solution
A modular holder element within the cooling device that can be moved from a normal cooling position to a rapid cooling position, positioned close to a cold air deflector, allowing direct passage of cold air for enhanced cooling efficiency, along with a control system and drive means to automate the transition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If bottles are placed in the freezer compartment for rapid cooling, then the cooling speed is improved, but the bottles may be overcooled or frozen causing liquid expansion and potential explosion
Solution Approach 1:
The holder element is designed to be movable between a normal cooling position and a rapid cooling position. This dynamic positioning allows the system to adapt the cooling intensity based on user needs, enabling rapid cooling when required while preventing overcooling by allowing easy repositioning to a milder cooling zone.
Solution Approach 2:
The cooling device provides different cooling conditions in different spatial locations. The area close to the evaporator offers intense rapid cooling, while other areas provide moderate normal cooling. Users can select the appropriate cooling intensity by placing bottles in different positions within the holder element.
2Productivity
If bottles are placed close to the evaporator for rapid cooling, then the cooling efficiency is improved, but the temperature control becomes difficult leading to overcooling
Solution Approach 1:
The holder element can be dynamically repositioned between a rapid cooling position near the evaporator and a normal cooling position farther away. This allows users to easily adjust the cooling intensity by simply moving the holder, providing precise temperature control without complex mechanisms.
3Device complexity
If a fixed holder element is used in the cooling device, then the device structure is simple, but rapid cooling functionality cannot be provided
Solution Approach 1:
The holder element is designed to be movable along the shelf rather than fixed. This simple linear movement capability enables the holder to access different cooling zones, providing rapid cooling functionality without requiring complex mechanical systems. The holder can be easily slid between positions to activate rapid cooling when needed.
4Productivity
If the holder element is moved to rapid cooling position frequently, then the cooling performance is improved, but the mechanical wear and positioning accuracy may deteriorate
Solution Approach 1:
The holder element uses a simple linear sliding mechanism along the shelf with stoppers defining discrete positions. This design minimizes mechanical complexity and potential failure points while enabling frequent repositioning. The stoppers provide reliable positioning without requiring complex locking mechanisms, balancing durability with the ability to frequently switch between cooling modes.

AI summary
The present invention relates to a cooling device comprising a heat-insulated body (10) into which items to be cooled are placed, as well as a cold air deflector (20) extending in the body (10) and dispensing cold air. The cooling device comprises a holder element (40), which can be moved in the body (10) from a normal cooling position, in which cold air leaving the deflector (20) is circulated within the body (10), to a rapid cooling position, in which the holder element (40) is brought to a position close to the deflector (20) so that cold air leaving the deflector is passed directly through the holder element (40) before being circulated within the body (10).
