Stackable Ventilation Units With Perpendicular Interlock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stackable ventilation units disrupt the structural continuity and aesthetic appeal of building walls by requiring sliding engagement, which damages the wall's integrity and allows easy removal, unlike conventional masonry bricks.
Innovation Solution
Ventilation units are designed to engage perpendicularly through formations and cooperating formations, preventing sliding and ensuring secure attachment with cement, maintaining wall integrity and allowing staggered or aligned stacking without disrupting the brick layout.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ventilation units are engaged by sliding one on top of the other, then the ventilation units can be easily installed and stacked, but cement is knocked off adjacent bricks causing damage to the structural integrity of the wall
Solution Approach 1:
Instead of sliding the ventilation unit horizontally across the brick surface (conventional method), the patent inverts the engagement direction to be perpendicular to the surface, with formations protruding outward and engaging into corresponding recesses. This reversal of the engagement direction eliminates the harmful sliding action that knocks cement off bricks while maintaining ease of installation.
2Ease of operation
If ventilation units are engaged by sliding one on top of the other, then the installation process is simple, but the ventilation units can be easily removed by sliding them out of the wall
Solution Approach 1:
The patent reverses the engagement mechanism from horizontal sliding to perpendicular insertion with formations and recesses. This inversion creates a secure mechanical interlock that prevents easy removal while maintaining simple installation, as the units can still be pushed in perpendicular to the surface but cannot be easily extracted without damage.
Solution Approach 2:
The ventilation unit is segmented into distinct engagement features: formations protruding from one surface and corresponding recesses on the opposing surface. This segmentation creates discrete mechanical interlocks that provide secure attachment while allowing for straightforward installation and removal of individual units if needed.
3Quantity of substance
If ventilation units are stacked in alignment with each other, then the level of ventilation is increased, but the normal staggered arrangement of masonry bricks is interrupted disrupting structural continuity and aesthetic appeal
Solution Approach 1:
The ventilation units are designed with universal engagement features (formations and recesses) that allow them to be stacked in multiple configurations - both aligned and staggered arrangements are possible. This multi-functionality enables the builder to maintain the traditional staggered brick pattern for structural continuity and aesthetics while still achieving increased ventilation through multiple stacked units.

AI summary
A set of ventilation units comprises a first and second ventilation unit, wherein a surface of the first ventilation unit is provided with at least one formation and a surface of the second ventilation unit is provided with at least one co-operating formation. The formation(s) and co-operating formation(s) is/are engageable with one another in a direction substantially perpendicular to said surface of the first ventilation unit and/or said surface of the second ventilation unit.
