Window Ventilation Element to Reduce Frame Slot Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing supply air windows require multiple slits in the window frame and sashes, which complicates their structure and increases the need for cutting slots, whereas the goal is to simplify the design and reduce slotting while maintaining effective air routing.
Innovation Solution
A ventilation element with a base part, supports for filters, and fixing parts that attach the base part inside the window at a distance from the frame, allowing for adjustable air flow regulation through tiltable regulators and air guides, eliminating the need for some slots by using filter supports that do not require adhesives and allowing for easy cleaning or replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple slits are made in the window frame and sashes to form air routes, then air routing functionality is achieved, but the structure becomes more complex and manufacturing becomes more difficult
Solution Approach 1:
The patent extracts the air routing function from the window frame and sash structure by introducing a separate ventilation element. This element contains the inlet and outlet openings and air guiding features, eliminating the need to cut slits in the main window structure. The ventilation element is attached to the window pane, providing air routing functionality independently of the frame and sash complexity.
Solution Approach 2:
The ventilation system is segmented into a separate attachable element rather than being integrated into the window frame and sash. This segmentation allows the air routing functionality to be provided by a modular component that can be added or removed without modifying the main window structure, thereby reducing structural complexity while maintaining functionality.
2Adaptability or versatility
If multiple slits are cut in the window frame and sashes, then air flow routes are created, but the manufacturing process becomes more difficult and time-consuming
Solution Approach 1:
The air flow routing function is extracted from the window manufacturing process by providing it through a separate ventilation element. This element comes pre-formed with inlet/outlet openings and air guiding features, eliminating the need to cut slots during window frame and sash manufacturing. The ventilation element is simply attached to the completed window pane, significantly simplifying the manufacturing process.
3Device complexity
If a ventilation element is attached inside the window at a distance from the frame, then the structure is simplified and slot cutting is reduced, but the element needs effective fixing parts to maintain position
Solution Approach 1:
The fixing parts are designed to be adjustable and adaptable rather than rigid and fixed. The suction cups can be positioned at different locations on the ventilation element, allowing the element to be securely attached at various distances from the frame while maintaining reliable positioning. This dynamic attachment system provides both structural simplification and reliable fixation.
