Window Insert Arrangement for Controlled Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation systems in occupant rooms often suffer from poor ventilation, leading to high humidity, mold, and temperature issues, which conventional heaters are insufficient to address.
Innovation Solution
A window ventilation arrangement featuring a slidable window assembly and a window insert arrangement with panel spacers, allowing for adjustable airflow and improved temperature control by reducing the air-letting opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the air-letting opening is reduced to control temperature and humidity, then temperature stability and humidity control are improved, but ventilation efficiency deteriorates
Solution Approach 1:
The window assembly is segmented into multiple components: a fixed window, a slidable window, and a panel with adjustable openings. This segmentation allows independent control of each component to optimize both temperature stability and ventilation efficiency. The panel can be positioned at different locations within the window frame to create controlled air-letting openings while maintaining overall temperature control.
Solution Approach 2:
The slidable window and panel are designed to be dynamically adjustable rather than fixed. The slidable window can move horizontally to adjust the size of air-letting openings, and the panel can be repositioned within the window frame to control airflow paths. This dynamic adjustment capability allows the system to adapt between maximizing ventilation efficiency and maintaining temperature stability based on environmental conditions.
2Temperature
If conventional heaters are used to address cold temperatures and humidity, then temperature increase is achieved, but the root cause of poor ventilation remains unresolved
Solution Approach 1:
The invention extracts and addresses the root cause of the problem (poor ventilation) rather than merely treating the symptom (cold temperature). By providing a window assembly with controlled air-letting openings, the system enables proper ventilation that naturally regulates temperature and humidity, eliminating the need for conventional heaters to compensate for poor ventilation.
Solution Approach 2:
The invention converts the harmful effect of cold air infiltration through poor ventilation into a beneficial controlled airflow system. The adjustable panel and slidable window mechanism allow cold air to be introduced in a controlled manner, mixing with warmer indoor air to provide natural temperature regulation and fresh air circulation, thereby eliminating the need for additional heating while maintaining comfort.
3Productivity
If the window is fully opened to improve ventilation, then air quality improves, but temperature control deteriorates during extreme temperature fluctuations
Solution Approach 1:
The panel introduces local quality variation by creating specific localized air-letting openings within the window assembly rather than requiring the entire window to be open. The panel can be positioned to create openings at specific locations, allowing controlled airflow paths that maintain temperature control while providing adequate ventilation. Different portions of the window assembly can have different levels of openness to optimize both ventilation and temperature control.

AI summary
A window ventilation arrangement includes a window assembly and a window insert arrangement. The window assembly includes a window frame and a slidable window. The frame includes an insert-receiving channel and is configured to provide an air-letting opening. The slidable window is displaceable within the window channel portion so as to provide the air-letting opening. The window insert arrangement includes a panel and a plurality of panel spacers. The panel has four corners, a first panel edge, a second panel edge, and a panel thickness. The panel spacers are attached to the panel at least at the four corners for providing an overall insert thickness equaling an insert channel width of an insert-receiving channel of the slidable window. The window insert arrangement is insertable into the insert-receiving channel of the slidable window and exposed portions of the panel providing a reduced, air-letting opening for reductively ventilating the room.
