Indoor ventilation system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional windows for ventilation compromise insulation, safety, and aesthetics, and pose health risks due to pollution when opened, especially in polluted areas.
Innovation Solution
An indoor ventilation system with opening parts in window glass and a sealing mechanism that includes a ring-shaped fixing frame and operation parts, allowing for controlled ventilation without the need for traditional window sashes and frames, enhancing safety and aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional openable windows are used for ventilation, then air circulation is improved, but insulation performance deteriorates
Solution Approach 1:
The window is divided into a fixed transparent portion and a separate operable vent portion. The vent can be opened independently from the main window pane, allowing air circulation without compromising the insulation of the main window structure. This segmentation enables selective ventilation while maintaining thermal efficiency.
Solution Approach 2:
A frame structure serves as an intermediary element that houses both the fixed transparent pane and the movable vent. This frame acts as a mediator that allows the vent to open for air circulation while the fixed pane remains in place to maintain insulation performance.
2Productivity
If conventional openable windows are used for ventilation, then air circulation is improved, but safety deteriorates
Solution Approach 1:
By separating the ventilation function into a small independent vent from the main window structure, the opening size is limited. This prevents children from falling through while still providing adequate air circulation. The segmentation isolates the safety risk to a minimal area.
Solution Approach 2:
The vent portion is designed with locally appropriate characteristics - a small opening size that provides sufficient ventilation airflow while being too small to pose a fall hazard. This local quality optimization resolves the safety concern without sacrificing ventilation effectiveness.
3Productivity
If conventional openable windows are used for ventilation, then air circulation is improved, but aesthetics deteriorates
Solution Approach 1:
The window is segmented into a large fixed transparent portion that maintains aesthetic continuity and a small separate vent portion. The fixed portion provides an unobstructed view, while the small vent opening does not significantly impact the overall visual appearance, thus preserving aesthetics while enabling ventilation.
Solution Approach 2:
The vent portion can be designed to match the aesthetic style of the main window frame, creating a harmonious appearance. The vent operates independently but visually integrates with the overall window design, maintaining aesthetic quality.
4Productivity
If conventional openable windows are used for ventilation, then air circulation is improved, but cost deteriorates
Solution Approach 1:
The window system is segmented into a simple fixed pane and a separate vent assembly. This segmentation allows the use of simpler, less expensive materials and construction methods for each component, reducing overall cost compared to a fully operable window system with complex framing and sealing requirements.
Solution Approach 2:
The vent portion can be constructed with simpler, more cost-effective materials since it does not require the same level of structural support and sealing as a full window. This use of simpler components for the ventilation function reduces manufacturing and installation costs.

AI summary
A system for selectively opening and closing a ventilation opening in a window glass panel. The system includes a shield gasket and a ring-shaped fixing frame inserted into the opening, with the gasket interposed between the opening and the fixing frame. A cover is inserted into the fixing frame to open and close the ventilation opening. Fixing frame alternatives include wherein the fixing frame comprises a drain structure, an exterior gutter, a filter, and peripheral elastic support hooks. Shield gasket alternatives include wherein a body part transforms into a cylindrical shape during installation of the fixing frame, and wherein a wall part comprises a circumferential elastic protruding part forming an inner space part therein. Cover alternatives include wherein the cover includes ring shaped shielding walls and a hook to engage fixing frame insertion groove.
