Solution Overview

Problem

Conventional beverage cooling systems face challenges in efficiently cooling large volumes of beverages with varying temperatures and compositions while maintaining consistency and energy efficiency, as dry block coolers are energy-intensive for large volumes and ice bath coolers react slowly to temperature changes.

Innovation Solution

A beverage cooling system integrating a dry block cooling unit with one or more cooling buffer units, combining rapid initial cooling with consistent temperature maintenance, using a control system to regulate operation and flow based on temperature and flow data, and incorporating a recirculation conduit for efficient heat exchange.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If a dry block cooling unit is used, then rapid initial cooling is achieved, but energy consumption increases for large volumes

Engineering Contradiction:
Improvecooling speedVSAvoidenergy consumption
Core Design Contradiction:
SpeedVSUse of energy by moving object

Solution Approach 1:

The cooling system is segmented into two distinct units: a dry block cooling unit for rapid initial cooling and a cooling buffer unit for sustained cooling. This segmentation allows each unit to operate optimally - the dry block provides fast cooling when needed while the buffer maintains temperature with minimal energy input, resolving the contradiction between cooling speed and energy consumption.

Inventive Principle:
Principle #1Segmentation

2Quantity of substance

If a cooling buffer unit is used, then large volumes of beverages can be cooled, but response to temperature changes is slow

Engineering Contradiction:
Improvebeverage volumeVSAvoidtemperature response speed
Core Design Contradiction:
Quantity of substanceVSSpeed

Solution Approach 1:

The cooling buffer unit is pre-cooled before beverage dispensing begins. This preliminary cooling action ensures that when large volumes of beverage are dispensed, the pre-cooled buffer immediately provides the necessary cooling capacity without delay, resolving the contradiction between handling large volumes and maintaining fast temperature response.

Inventive Principle:
Principle #10Preliminary action

3Ease of repair

If a dry block cooling unit is used, then easy maintenance is achieved, but cooling capacity is insufficient for large volumes

Engineering Contradiction:
Improvemaintenance easeVSAvoidbeverage cooling capacity
Core Design Contradiction:
Ease of repairVSQuantity of substance

Solution Approach 1:

The system merges a dry block cooling unit (which is easy to maintain) with a cooling buffer unit (which provides large volume cooling capacity). The dry block handles the cooling function with minimal maintenance requirements while the buffer provides the necessary capacity for large volumes, allowing both maintenance ease and high cooling capacity to coexist.

Inventive Principle:
Principle #5Merging (Combining)

4Device complexity

If conventional cooling systems are used, then simple structure is maintained, but temperature consistency varies

Engineering Contradiction:

Solution Approach 1:

The system incorporates temperature sensors that continuously monitor the beverage temperature and provide feedback to the control system. This feedback mechanism allows the system to automatically adjust cooling operations to maintain consistent temperature, resolving the contradiction between structural simplicity and temperature consistency through intelligent control.

Inventive Principle:
Principle #23Feedback
