Solution Overview

Problem

Existing heating system control methods fail to account for heat stored in rooms, leading to unnecessary high heating and energy consumption when windows are opened, causing the system to overshoot the target temperature.

Innovation Solution

A method that monitors the actual room temperature and its gradient, using the last measured temperature before a window opening to control the heat generator when the gradient indicates a window is open, and continuing to use this temperature even after the window is closed to utilize stored heat for reheating, while avoiding high energy expenditure and temperature overshooting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the heat generator heats with high output after window closing to restore target temperature, then the room temperature is brought back to target level, but energy consumption increases unnecessarily and temperature overshooting occurs

Engineering Contradiction:
Improveroom temperature restorationVSAvoidenergy consumption
Core Design Contradiction:
TemperatureVSUse of energy by moving object

Solution Approach 1:

The system detects window opening in advance and preemptively reduces heat generator output before the window is closed, rather than reacting after temperature drops. This preliminary action prevents unnecessary heating cycles and utilizes stored heat in building structures, avoiding energy waste and temperature overshooting while maintaining comfortable temperature levels.

Inventive Principle:
Principle #10Preliminary action

2Speed

If the heat generator operates at full load after window closing, then the room is heated quickly, but the stored heat in floors, walls and furnishings causes overshooting of target temperature

Engineering Contradiction:
Improveheating speedVSAvoidtemperature overshooting
Core Design Contradiction:
SpeedVSTemperature

Solution Approach 1:

The system continuously monitors room temperature and detects window opening events by analyzing temperature gradients. When window opening is detected, the control device adjusts heat generator output based on feedback from temperature sensors, preventing both excessive heating and temperature overshooting by adapting to real-time thermal conditions and stored heat release patterns.

Inventive Principle:
Principle #23Feedback
