Telescopic Chimney Pipe Connector for Variable Fireplace Heights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The diverse designs and dimensions of fireplaces result in non-standardized positions for air supply and exhaust gas connections, necessitating exact dimension knowledge or adapter devices for chimney pipe installation, particularly complicating the adjustment of supply air connections located near the floor.
Innovation Solution
A connection base with a height-adjustable air inlet connector, featuring a telescopic connecting pipe element and a spiral guide device, allowing the air inlet connector to be raised or lowered relative to the base element, and a cover sleeve for gas-tight closure, enabling flexible positioning of the air supply socket from a few centimeters above the floor to several decimeters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-position air inlet connector is used in conventional chimney systems, then the installation structure is simple, but it cannot accommodate diverse fireplace connection positions particularly when supply air connections are located near the floor
Solution Approach 1:
The air inlet connector is made dynamically adjustable through a telescopic connection mechanism with a connecting pipe element that can slide axially within the base element. This allows the connector position to be dynamically changed to match diverse fireplace connection positions, particularly for supply air connections near the floor, while maintaining a relatively simple overall structure.
Solution Approach 2:
The connection base is segmented into multiple functional elements: a base element, a telescopic connecting pipe element, and an air inlet connector. This segmentation allows independent adjustment of the connector position while keeping each component structurally simple, resolving the contradiction between adaptability and structural complexity.
2Ease of manufacture
If exact dimensions of fireplace connections are known in advance, then adapter devices are not needed, but precise measurement and planning are required before installation
Solution Approach 1:
The connection base is designed with preliminary adjustable features including the telescopic connecting pipe element and height-adjustable air inlet connector. These preliminary design features allow installation personnel to adjust the connection position during installation without needing to perform precise measurements and calculations in advance, reducing planning time while eliminating the need for adapter devices.
3Ease of operation
If the air inlet connector position is fixed during manufacturing, then production is simple and cost-effective, but field adjustment is impossible
Solution Approach 1:
The air inlet connector incorporates a telescopic connecting pipe element with sliding capability and axial play, enabling field adjustment of the connector position. The mechanism includes a spiral guide device for height adjustment and a locking mechanism to secure the adjusted position. This dynamic design allows easy field adjustment while maintaining relatively simple manufacturing processes for each component.
