Roller or blind box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of decentralized ventilation systems in buildings with aligned openings is visually unappealing and requires significant effort, as existing roller shutter or Venetian blind boxes do not provide a defined mounting position for ventilation devices, necessitating irregular openings in the exterior facade.
Innovation Solution
A roller shutter or blind box design with a second cavity separated by a wall, housing a ventilation device pipe that extends through the outer and inner walls, providing a defined mounting interface and eliminating the need for additional openings, with a pipe geometry adapted to the ventilation device and insulated for thermal efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If decentralized ventilation systems are installed with separate openings in the exterior wall, then ventilation functionality is achieved, but the installation requires significant effort and creates visual irregularity on the facade
Solution Approach 1:
The patent combines the ventilation device installation with the existing roller shutter box structure. The ventilation device is mounted on the inner wall of the roller shutter box, which already provides a defined mounting position. This merging eliminates the need for separate facade openings and reduces installation complexity while maintaining visual uniformity of the facade.
2Adaptability or versatility
If separate openings are created in the exterior wall for ventilation, then ventilation devices can be installed, but the openings cannot be guaranteed to be correctly aligned resulting in irregular cover positions
Solution Approach 1:
The roller shutter box serves multiple functions: it houses the roller shutter mechanism and simultaneously provides a pre-defined mounting position for the ventilation device. The inner wall of the box acts as a universal mounting surface that ensures correct alignment with the facade, eliminating the need for separate opening creation and ensuring uniform cover positioning.
3Ease of manufacture
If the roller shutter box is extended to create a second cavity for the ventilation device, then a defined mounting interface is provided, but the box structure becomes more complex
Solution Approach 1:
The roller shutter box is segmented into two functional cavities: the first cavity for the roller shutter mechanism and the second cavity (formed by extending the box) for the ventilation device. This segmentation provides a defined mounting interface for the ventilation device while keeping the overall structure relatively simple through modular design.
