Solution Overview
Problem
Existing window control systems do not effectively utilize temperature differentials to optimize heating and cooling by automatically adjusting window positions based on current and target indoor and outdoor temperatures, leading to inefficient energy use and comfort issues.
Innovation Solution
A system that periodically or continuously monitors indoor and outdoor temperatures and adjusts window positions between closed and open states to facilitate natural airflow for heating or cooling, prioritizing a window-based subsystem over a ducts-based subsystem when temperature differentials are significant, and transitions between the two based on effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If window-based natural airflow system is used for heating or cooling, then energy efficiency is improved and energy costs are reduced, but the system cannot effectively regulate temperature when temperature differentials are insufficient
Solution Approach 1:
The system dynamically switches between window-based natural airflow mode and ducts-based forced airflow mode based on real-time temperature differential conditions. When the temperature differential between indoor and outdoor environments is sufficient, the system uses energy-efficient natural airflow through windows. When the temperature differential is insufficient, the system automatically transitions to ducts-based forced airflow to ensure reliable temperature regulation, thus resolving the contradiction between energy efficiency and temperature regulation effectiveness.
Solution Approach 2:
The system monitors temperature differential parameters and changes operational mode based on threshold conditions. By detecting when the temperature differential falls below a predetermined threshold, the system switches from window-based to ducts-based operation, ensuring that temperature regulation effectiveness is maintained while maximizing energy efficiency during favorable conditions.
2Measurement precision
If the system continuously monitors and adjusts window positions, then temperature control precision is improved, but device complexity increases
Solution Approach 1:
The system automatically monitors temperature conditions and adjusts window positions without requiring manual intervention. The automated control logic evaluates temperature differentials and triggers appropriate actions, improving temperature control precision while minimizing the need for complex manual control interfaces and reducing overall system operational complexity.
Solution Approach 2:
The system implements continuous temperature monitoring with feedback control mechanisms. Temperature sensors provide real-time data to the control system, which adjusts window positions based on detected temperature differentials. This closed-loop feedback approach ensures precise temperature control while using simple, straightforward control logic that does not significantly increase system complexity.
3Loss of energy
If the system prioritizes window-based subsystem over ducts-based subsystem, then energy costs are reduced, but the ability to meet temperature requirements during extreme conditions is compromised
Solution Approach 1:
The system dynamically adapts its operational strategy based on environmental conditions. During moderate temperature conditions, the system prioritizes energy-efficient window-based natural airflow. During extreme temperature conditions when natural airflow becomes insufficient, the system automatically transitions to ducts-based forced airflow, ensuring the ability to meet temperature requirements across a wide range of environmental conditions while maximizing energy savings during favorable periods.
Solution Approach 2:
The system uses temperature forecasting and threshold-based triggers to initiate cooling or heating actions in advance. By monitoring predicted temperature trends and triggering window adjustments or ducts operation before extreme conditions fully develop, the system proactively maintains comfortable temperatures while minimizing energy consumption, thus resolving the contradiction between energy savings and temperature adaptability.

AI summary
Techniques for heating and/or cooling a structure including are described. The system may determine that a current indoor temperature is higher than both the current outdoor temperature and the target indoor temperature. Based on the determination, the system (in a cooling mode) may determine that a window opening criteria is met for opening one or more windows. Responsive to determining that the window opening criteria has been met, the system may instruct a window control mechanism to modify a state of the window from (a) a closed position that prevents airflow through the window to (b) an open position that allows for airflow through the window to cool a structure. Similarly, the system in a heating mode may open one or more windows when the current indoor temperature is lower than both the target indoor temperature and the current outdoor temperature.
