Telescoping Flue Gas Outlet Assembly for Compact Roof Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flue gas outlet assemblies require large packaging, storage, and transportation volumes, and are cumbersome to handle and install, especially when dealing with roof installations.
Innovation Solution
A flue gas outlet assembly comprising separable tubular parts that telescope into each other in a pre-operational condition, allowing for reduced packaging and storage volume, and a method to transition these parts into an operational configuration suitable for installation, involving separation and rotation to achieve the expanded length needed for roof placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flue gas outlet assembly is provided as a single integrated unit, then the structural integrity and operational reliability are maintained, but the packaging, storage, and transportation volume increases significantly
Solution Approach 1:
The flue gas outlet assembly is divided into multiple separate tubular parts (inner tube and outer tube) that can be packaged independently or nested within each other, significantly reducing the required packaging volume compared to a single integrated unit while maintaining structural integrity through designed connection mechanisms
Solution Approach 2:
The inner tubular part is designed to be inserted into the outer tubular part for packaging and transportation, creating a compact nested configuration that minimizes packaging volume. The connection ends are dimensioned to allow this nesting arrangement while ensuring proper alignment and structural stability during installation
2Volume of stationary object
If the flue gas outlet assembly is divided into separate tubular parts, then the packaging and storage volume is reduced, but the complexity of assembly and installation increases
Solution Approach 1:
The assembly is segmented into modular tubular parts with standardized connection interfaces, allowing for simplified handling and transportation while reducing installation complexity through pre-designed connection mechanisms that guide proper assembly
Solution Approach 2:
The connection ends of the tubular parts are pre-dimensioned and pre-configured with specific geometric features (such as tapered surfaces or interlocking profiles) that automatically guide the parts into correct alignment during assembly, eliminating the need for complex alignment procedures and reducing installation complexity
3Volume of stationary object
If the tubular parts are dimensioned to slide into each other for compact packaging, then the packaging efficiency is improved, but the precision required for connection ends increases
Solution Approach 1:
The connection ends are designed with tapered surfaces or interlocking profiles that provide self-aligning features during the nesting process, reducing the manufacturing precision requirements compared to tight-fit cylindrical connections while still achieving compact packaging and stable assembly
