Window arrangement with an interior lining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window assemblies with inner linings for skylights lack a flexible ventilation option that can maintain air exchange between the interior and exterior environments, especially when the window is closed.
Innovation Solution
Incorporating an additional air passage within the inner lining that allows for ventilation connections via a ventilation device, which can include an air box for air distribution or collection, and a cover frame that forms a nozzle-like structure with the wall surface to direct airflow, enabling air exchange even when the window is closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional inner lining with only a passage to the window is used, then the structure is simple and clear, but ventilation is only possible when the window is open, lacking flexibility
Solution Approach 1:
The inner lining is divided into functional segments: the original passage structure for window access and a new air passage system for ventilation. The air passage is separated into an air inlet area, air outlet area, and connecting flow path, allowing independent optimization of each segment's function while maintaining overall system simplicity
Solution Approach 2:
The inner lining is transformed from a single-function element (providing passage to window) to a multi-function component that simultaneously provides window access and independent ventilation capability. The air passage system enables the inner lining to perform both structural/access functions and active ventilation functions, increasing versatility without requiring separate ventilation infrastructure
2Adaptability or versatility
If an air passage is added to the inner lining for closed-window ventilation, then ventilation flexibility is improved, but the inner lining structure becomes more complex
Solution Approach 1:
The air passage components (air inlet, air outlet, and flow connection) are merged into and integrated with the inner lining structure itself. Rather than adding separate ventilation components, the air passage is formed as part of the inner lining's geometry, combining structural support and ventilation functions into a single unified element
Solution Approach 2:
The air passage is positioned and configured to exploit local characteristics of the inner lining structure. The air inlet and outlet are strategically located at specific positions on the inner lining to optimize airflow patterns and ventilation efficiency while maintaining the overall structural integrity and aesthetic quality of the inner lining
3Shape
If the air passage is completely enclosed by the inner lining, then the structure is clean and unobtrusive, but airflow distribution and volume are limited
Solution Approach 1:
The air passage is nested within the inner lining structure, with the air inlet and outlet areas positioned in recesses or integrated zones of the inner lining. This nesting approach allows the air passage to be contained within the overall form of the inner lining, maintaining a clean external appearance while providing sufficient internal volume for effective airflow
Solution Approach 2:
The air passage utilizes three-dimensional space within and around the inner lining structure. By extending the air passage in multiple directions and utilizing vertical and lateral dimensions, the design achieves adequate airflow volume without requiring the air passage to protrude or be fully exposed, thus maintaining aesthetic quality while ensuring functional performance
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration provides a flexible and efficient ventilation system that maintains air turnover with low flow rates and noise reduction, ensuring optimal interior air quality without visible obstructions.
Implementation Method 1
The air box provides a comparatively large flow volume, which is preferably significantly larger than the flow volume of the air outlet. In particular, the flow volume of the air box is a multiple of the flow volume of the air outlet. In this respect, the air box is used for calming and the even distribution of the air flowing into or out of it.
Implementation Method 2
the ventilation device can have, for example, an active air conveying device, by means of which air is conveyed from the interior, for example in the direction of the outside environment and/or vice versa
