Solution Overview

Problem

Current animal barn air conditioning systems lack intelligent control routines that consider both current and historical weather parameters, leading to suboptimal climate control and potential animal welfare issues.

Innovation Solution

A building climate control system that assigns the current climate situation to one of several predetermined thermal phases based on monitored temperature exceedances and undershoots over defined periods, adjusting ventilation and other climate conditioning devices accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current animal barn air conditioning systems only consider individual control-relevant parameters without intelligent control routines, then the system operation is simple, but the climate control effectiveness and animal welfare are suboptimal

Engineering Contradiction:
Improveclimate control effectivenessVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The control device stores weather parameters from previous days and pre-determines thermal phases before control decisions are made. This preliminary action allows the system to anticipate climate changes and adjust ventilation proactively, improving climate control effectiveness while maintaining manageable complexity through structured prediction algorithms.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors current weather parameters, compares them with stored historical data, and adjusts ventilation settings based on the determined thermal phase. This feedback loop ensures optimal climate control by constantly adapting to changing conditions while using structured decision rules to keep control complexity manageable.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If the system assigns current climate situation to thermal phases based on weather parameters recorded over previous phase determination periods, then predictive climate control is achieved, but the response time and computational requirements increase

Engineering Contradiction:
Improvepredictive control capabilityVSAvoidphase determination time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The control approach segments the climate control into distinct thermal phases (cold phase, intermediate phase, warm phase) with specific temperature ranges and control specifications. This segmentation allows the system to use simple lookup tables and predefined control rules for each phase, reducing computational complexity and response time while maintaining predictive capability through historical weather data integration.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If thermal phase-specific control specifications are implemented for different weather scenarios, then climate-adapted air conditioning is achieved, but the control logic complexity increases

Engineering Contradiction:
Improveclimate adaptation precisionVSAvoidcontrol logic complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system changes control parameters (ventilation opening degrees, fan speeds) based on the determined thermal phase. Each thermal phase has predefined parameter ranges and control specifications that simplify the control logic. The control device selects appropriate parameters from stored specifications based on the current thermal phase, achieving climate-adapted control without complex real-time calculations.
