Solution Overview

Problem

Existing temperature regulation methods for output fluids in systems like building installations and appliances struggle to efficiently adapt to local conditions and maintain setpoint temperatures, leading to inefficiencies and user discomfort.

Innovation Solution

A method where a control unit adjusts a control parameter for the heat transfer medium based on measured values and setpoint temperatures, using a PI controller with adaptive settings and pre-control parameters to optimize heat transfer, and stores end values as new starting values for future dispensing, allowing for quick adaptation to site-specific conditions and maintaining temperature stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a control parameter is adjusted during dispensing to maintain setpoint temperature, then temperature regulation precision is improved, but the system cannot adapt to local conditions and system changes

Engineering Contradiction:
Improvetemperature regulation precisionVSAvoidadaptability to local conditions
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The control parameter determined at the end of the current dispensing is stored and used as the starting value for the next dispensing operation. This preliminary action allows the system to adapt to local conditions and system changes that occur during dispensing, while maintaining temperature regulation precision during the actual dispensing process by using the pre-adapted starting value.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If the control parameter is continuously adjusted during dispensing, then temperature stability is improved, but the response time to reach setpoint temperature increases

Engineering Contradiction:
Improvetemperature stabilityVSAvoidresponse time to setpoint
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The control parameter is determined and stored at the end of the current dispensing operation, serving as a pre-adapted starting value for the next dispensing. This preliminary adaptation reduces the adjustment range needed during the next dispensing, thereby decreasing the response time to reach setpoint temperature while maintaining temperature stability through controlled adjustments during the dispensing process.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If adaptive control parameters are used for each dispensing operation, then adaptability to system changes is improved, but memory and computational requirements increase

Engineering Contradiction:
Improveadaptability to system changesVSAvoidmemory and computational requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Only the control parameter at the end of each dispensing operation is extracted and stored for use as the starting value of the next dispensing. This selective extraction approach provides adaptability to system changes while minimizing memory requirements by storing only the essential parameter rather than complete control histories or complex adaptive models.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of operation

If the control parameter is optimized for each dispensing event, then user comfort is improved, but energy consumption increases

Engineering Contradiction:
Improveuser comfortVSAvoidenergy consumption for temperature regulation
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The control parameter determined at the end of the current dispensing is stored and used as the starting value for the next dispensing. This preliminary optimization reduces the adjustment range and energy required during each subsequent dispensing operation, thereby improving user comfort through consistent temperature control while decreasing overall energy consumption.

Inventive Principle:
Principle #10Preliminary action
