Flexible Exhaust Boot Mounting for Variable Window Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exhaust systems for construction sites face challenges in accommodating variable window sizes and frameworks, making it difficult to effectively draw air and dust from enclosed rooms to the external environment.
Innovation Solution
A portable exhaust system comprising an exhaust fan with a flexible boot and a support assembly that includes adjustable brackets and straps, allowing secure attachment to various window frameworks, enabling efficient air and dust removal regardless of window size or framework configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fixed exhaust system is installed to effectively remove air and dust, then exhaust performance is improved, but adaptability to variable window sizes and frameworks deteriorates
Solution Approach 1:
The support assembly incorporates adjustable vertical and horizontal brackets that can be positioned at different heights and angles, allowing the exhaust system to adapt to various window sizes and framework configurations while maintaining effective exhaust performance
Solution Approach 2:
The support assembly is designed with universal mounting capabilities that can accommodate different window types and sizes through adjustable brackets and positioning mechanisms, making a single exhaust system suitable for multiple application scenarios
2Adaptability or versatility
If a portable exhaust system is used to accommodate variable window sizes, then adaptability is improved, but exhaust performance deteriorates
Solution Approach 1:
The adjustable support assembly maintains optimal exhaust performance across different window configurations by allowing dynamic repositioning of the exhaust fan to ensure proper alignment and airflow regardless of window size or framework variations
3Stability of the object's composition
If a rigid support structure is used to secure the exhaust fan, then stability is improved, but adaptability to different window frameworks deteriorates
Solution Approach 1:
The support assembly uses adjustable brackets with positioning mechanisms that provide stable mounting when set, yet can be reconfigured for different window frameworks, combining stability with adaptability
Solution Approach 2:
The support assembly is divided into separate adjustable components (vertical bracket, horizontal bracket, positioning blocks) that can be independently adjusted to match different window frameworks while maintaining overall stability

AI summary
An exhaust system includes an exhaust fan having a frame within which fan blades and a motor are secured. The frame includes an upper sidewall, a bottom sidewall, a first lateral sidewall and a second lateral sidewall, defining an inlet opening and an outlet opening on opposite sides of the frame. A flexible exhaust boot is secured to the frame of the exhaust fan adjacent the outlet opening. The exhaust boot is a flexible piece of material having a substantially tubular configuration with a first end having an opening and a second end having an opening. A support assembly secures the exhaust fan and exhaust boot in position adjacent an opening. The support assembly includes a vertical bracket having a first end and a second end, and an outwardly extending support block is mounted at the first end of the vertical bracket. The support assembly also includes a horizontal bracket extending substantially perpendicular to the vertical bracket. The horizontal bracket is shaped and dimensioned to pass through a connection opening in the second end of the vertical bracket, and the horizontal bracket includes first end and a second end. The first end of the horizontal bracket extends outwardly from the same side of the vertical bracket as the support block. A strap is selectively connected to the exhaust fan.
