Modular Beverage Cooler for Swappable Refrigeration Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beverage coolers are inflexible, requiring complete replacement for changes in refrigerant type, cooling capacity, or installation site issues, leading to high costs and downtime, as they are not modular and cannot be easily adapted or serviced without specialized personnel.
Innovation Solution
A modular beverage cooling system with independently removable and connectable refrigeration, pumping, and cooling modules, using a secondary cooling medium and a dual-spindle motor to operate both the pump and fan, allowing for easy maintenance, capacity adjustments, and refrigerant changes without disrupting operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional beverage coolers use integrally constructed refrigeration systems with permanent joints, then system reliability is improved, but ease of repair deteriorates because entire coolers must be replaced upon failure
Solution Approach 1:
The beverage cooler is divided into separate modular components: a refrigeration module containing the compressor and evaporator, and a beverage cooling module containing the cooling tank. These modules are connected via removable couplings rather than permanent joints, allowing the refrigeration module to be independently removed and replaced if it fails, without needing to replace the entire cooler system.
2Ease of manufacture
If conventional beverage coolers are correctly sized at installation, then initial cost efficiency is improved, but adaptability deteriorates because capacity cannot be increased for future market growth
Solution Approach 1:
The system allows dynamic adjustment of cooling capacity by replacing the refrigeration module with different sized modules. The removable coupling enables the user to swap between refrigeration modules of varying capacities as market conditions change, transforming a static system into a dynamically adaptable one without requiring complete system replacement.
3Reliability
If conventional beverage coolers are designed with specific refrigerant types, then initial system performance is improved, but adaptability deteriorates because refrigerant changes require complete replacement
Solution Approach 1:
By segregating the refrigerant-containing components (compressor, evaporator, refrigerant charge) into a separate refrigeration module that can be independently removed, the system allows refrigerant type changes without affecting the beverage cooling module. Users can replace the entire refrigeration module with one designed for different refrigerant types (R134a, R404A, R448A, etc.) while retaining the same cooling tank and beverage handling components.
4Ease of operation
If conventional beverage coolers are installed in fixed locations, then installation simplicity is improved, but adaptability deteriorates because relocation or reconfiguration is difficult
Solution Approach 1:
The separation of the refrigeration module from the beverage cooling module via removable couplings enables flexible reconfiguration and relocation. The beverage cooling module can be moved to different positions or reconfigured with different tank sizes while keeping the refrigeration module in place, or vice versa, providing installation flexibility without complex re-piping or re-soldering operations.

AI summary
A beverage cooling system includes a main assembly having a refrigeration module, a pumping and control module, and a beverage cooling module. The refrigeration module has a refrigeration system cooling a cooling medium. The beverage cooling module has a cooling tank cooled by the refrigeration system. The pumping and control module has a pump to pump a beverage ingredient cooled by the refrigeration system. Each of the refrigeration module, the pumping and control module, and beverage cooling module are independently removable from and connectable to the remainder of the main assembly.
