Modular Drum Segment Ventilation Regulation with Mechanical Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation regulation systems require tedious manual adjustment of individual drum segments to control air flow, which is often not accomplished due to the labor-intensive nature of the task.
Innovation Solution
A modular air regulation drum member with rotatable segments linked by a mechanical coupling, actuated by parameters such as air debit, pressure, or temperature, allowing coordinated rotational movement to adjust air direction, speed, and debit rate automatically.

Engineering Contradiction Analysis
1Ease of operation
If individual drum segments are manually adjusted to control air flow, then air flow direction and speed can be controlled, but the operation becomes tedious and labor-intensive
Solution Approach 1:
Multiple drum segments are merged into a single integrated drum assembly where all segments are mechanically coupled together. This allows one actuator to rotate the entire assembly, controlling air flow direction and speed for all segments simultaneously, eliminating the need for manual adjustment of each segment individually
Solution Approach 2:
The drum assembly is designed to automatically respond to air flow conditions through a single actuator. The mechanical coupling between segments allows the system to self-regulate air distribution without requiring maintenance personnel to manually adjust each segment, making the system self-sufficient
2Adaptability or versatility
If multiple individual drums are provided for each ventilation opening, then each opening can be independently controlled, but the device complexity increases
Solution Approach 1:
The drum assembly is segmented into multiple rotatable segments that are mechanically coupled. Each segment can be independently positioned relative to the others through the mechanical coupling mechanism, allowing independent control of air flow for each segment while maintaining a unified structural assembly that reduces overall complexity
Solution Approach 2:
The mechanical coupling mechanism serves multiple functions: it connects all drum segments into a single rotatable assembly, allows independent positioning of segments, and enables control by a single actuator. This multi-functionality reduces the number of separate components needed, simplifying the overall device

AI summary
The ventilation regulation system comprises a ventilation duct including a ventilation opening through a separating wall of the ventilation duct. An air regulation apparatus is provided within the ventilation opening for regulating the air flow therethrough, and comprises a modular air regulation drum member that has a number of rotatable drum segments that can each rotate to adjustably block or deflect the air flow through the ventilation opening such that at least one among the direction, the speed and the debit rate of air is controlled through the ventilation opening. A mechanical coupling mechanically links the drum segments of the drum member into a coordinated rotational movement. An actuator acting on at least one, but not all, of the drum segments of the drum member, rotates one of the drum segments, with the mechanical coupling allowing all drum segments to be rotated when that one drum segment is rotated.
