Selectively closable ventilation opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation systems in confined spaces, such as bathrooms, often require visible components that occupy valuable space and are not easily concealed when not in use.
Innovation Solution
A ventilation assembly with a moveable trim assembly that can transition between a closed position to conceal the ventilation opening and an open position to allow airflow, incorporating a main housing, a blower, and a trim assembly with a lighting element or grille that can be retracted or extended to control airflow and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional exhaust fan grille is used, then ventilation function is provided, but the grille occupies visible space and is not aesthetically pleasing when not in use
Solution Approach 1:
The trim assembly is made movable between retracted and extended positions, allowing it to transition from a concealed state (when not ventilating) to an active state (when ventilating). This dynamic configuration enables the trim to occupy minimal visible space when retracted while still providing full ventilation function when extended.
Solution Approach 2:
The trim assembly is extracted from the fixed ceiling structure and made independently movable. By separating the trim from the permanent installation and making it retractable, the visible footprint is minimized when the ventilation function is not actively needed.
2Ease of repair
If ventilation components are made visible and accessible, then maintenance is easier, but space is occupied and aesthetics are compromised
Solution Approach 1:
The movable trim assembly allows easy access to the blower and internal components by simply retracting the trim, without requiring permanent access panels or exposed components. This maintains aesthetic appearance while providing convenient maintenance access.
3Productivity
If the trim assembly is extended to allow airflow, then ventilation function is improved, but the device occupies more space
Solution Approach 1:
The trim assembly dynamically adjusts between retracted and extended positions based on ventilation needs. When extended, it provides optimal airflow paths for maximum ventilation efficiency. When retracted, it minimizes occupied space to a sleek profile integrated with the ceiling.

Data Source
AI summary
A ventilation assembly having a moveable trim moveable between an open position in which the moveable trim defines a gap with a ceiling trim to allow movement of fluid and a closed position in which the moveable trim is against or adjacent to the ceiling trim to eliminate or reduce the gap and prevent or limit fluid flow.
