Vent Pipe Hat With Integrated Spirit Level for Vertical Roof Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of an exhaust ventilation pipe with a hat on an inclined roof often results in the pipe leaning, making it difficult to ensure vertical alignment without additional accessories.
Innovation Solution
Incorporating a circular spirit level integrated into the conical cup of the hat, allowing the installer to verify the pipe's vertical position easily, along with a ball-shaped collar and conical collar design for secure roof penetration and water drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an exhaust ventilation pipe is installed on an inclined roof, then the pipe can be mounted on the roof surface, but the pipe tends to lean and fails to maintain vertical alignment
Solution Approach 1:
The spirit level is integrated directly into the hat of the exhaust ventilation pipe, combining the mounting structure with the alignment verification function. This eliminates the need for separate alignment tools and makes vertical verification immediate and intuitive during installation.
Solution Approach 2:
The hat structure serves dual purposes: it acts as both the mounting component and the alignment indication device. The integrated spirit level allows the installation system to self-verify its vertical alignment without requiring external measurement tools or additional steps.
2Manufacturing precision
If a spirit level is added to verify vertical alignment, then alignment precision improves, but the device complexity increases
Solution Approach 1:
The spirit level is merged with the hat structure, so that what appears to be a single component actually performs multiple functions: structural support, weather protection, and alignment verification. This eliminates the need for separate alignment accessories.
Solution Approach 2:
The hat is transformed from a simple protective cover into a multi-functional component that simultaneously provides structural support, weather protection, and built-in alignment verification capability through the integrated spirit level.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates and accelerates the installation process by providing immediate visual confirmation of vertical alignment, preventing water ingress and ensuring a secure, watertight seal.
Implementation Method 1
A circular spirit lever 6 is integrated on the top of the conical cup 3 in the hat 2, by means of which an installer easily sees, when said exhaust ventilation pipe is in quite a vertical position, i.e. when the glass pearl of the spirit level is in the middle of the spirit level.
Implementation Method 2
The diameter of said conical cup 3 is smaller than the inner diameter of the hat 2, so that an annular slot is formed between the wall of the hat and the cup, through which rain water can flow down onto a conical collar 8 fastened by supporting arms 7 to the side wall of the hat 2, from which collar 8 the water flows out of the hat 2.
