Ventilation box and associated ventilation system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation boxes are impractical to produce due to the need for multiple models to accommodate different air tapping configurations, and they are limited to a single configuration once produced, making it difficult to control fluid exchange between the inside and outside of a room.
Innovation Solution
A ventilation box design featuring a plurality of external openings and a closure system that allows for the installation of either an air tap or a blocking member, enabling flexible configuration to control fluid exchange through a main internal opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple models of ventilation boxes are produced to accommodate different air tapping configurations, then adaptability is improved, but manufacturing complexity increases
Solution Approach 1:
The ventilation box is designed with multiple external openings that can each accommodate either an air tapping or a blocking member, allowing a single universal model to serve multiple configurations. The main internal opening with its closure system enables the box to adapt to different air intake positions without requiring multiple specialized models, thus improving adaptability while maintaining manufacturing simplicity.
2Ease of manufacture
If a ventilation box is designed for a single air tapping configuration, then manufacturing simplicity is improved, but adaptability deteriorates
Solution Approach 1:
The external casing is segmented into multiple external openings, each capable of independently accommodating an air tapping or a blocking member. This segmentation allows the ventilation box to be manufactured as a single standardized unit while providing flexibility in field configuration, thereby maintaining manufacturing simplicity while achieving adaptability.
3Adaptability or versatility
If external openings accommodate either air intake or blocking member, then versatility is improved, but control over fluid exchange deteriorates
Solution Approach 1:
The closure system is pre-configured to control the main internal opening that connects the exchange compartment to the transition compartment. This preliminary control mechanism allows users to manage fluid exchange between the room interior and exterior by controlling the main internal opening, thereby maintaining ease of operation despite the versatility provided by multiple external openings with different configurations.

AI summary
This ventilation unit (14) comprises: - an outer casing (22); - a main partition (24), arranged in the outer casing (22) to separate a heat exchange compartment (44) and a transition compartment (46); - external openings (26), supported by the outer casing (22); - a main internal opening (28) to fluidly connect the heat exchange compartment (44) and the transition compartment (46); and - a heat exchange opening to fluidly connect the heat exchange compartment (44) and the interior of the room.The ventilation box (14) includes a shuttering system (32), which evolves between a passage configuration, in which the shuttering system (32) allows fluid exchange between each unsealed external opening (26) and the exchange compartment (44), and a shuttering configuration, in which the shuttering system (32) prevents fluid exchange between each unsealed external opening (26) and the exchange compartment (44).
