Adjustable Fireplace Circulating Chamber for Flue and Insert Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fireplace inserts with small circulating chambers face limitations in air circulation and efficiency due to restricted dimensions, making them difficult to install and requiring powerful electric blowers.
Innovation Solution
An adjustable circulating chamber with bendable side walls and a trapezoidal top member featuring an oval opening and adjustable flange, paired with L-shaped brackets and sheet metal screws, allows for customizable fit within varying fireplace sizes and flue pipe dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a small circulating chamber is used to fit all fireplace sizes, then the insert can be universally installed, but air circulation and efficiency are restricted
Solution Approach 1:
The circulating chamber is designed with adjustable side walls that can be bent to different configurations, allowing the chamber size to be dynamically changed to match different fireplace dimensions. This resolves the contradiction by enabling both universal installation through adjustment and optimized air circulation through appropriate sizing.
Solution Approach 2:
The side walls are made bendable to change the dimensional parameters of the circulating chamber. By adjusting the bend angle and position, the chamber can be customized to fit various fireplace sizes while maintaining optimal air circulation characteristics for each configuration.
2Adaptability or versatility
If a small circulating chamber is used, then the insert can fit all fireplace sizes, but the installation becomes more complicated
Solution Approach 1:
The adjustable side wall design allows the circulating chamber to be configured on-site to match the specific fireplace dimensions, simplifying installation by eliminating the need for complex custom fabrication for each fireplace size.
Solution Approach 2:
The side walls are designed as separate, adjustable components rather than a fixed monolithic structure. This segmentation allows for easier handling, configuration, and installation while maintaining adaptability to different fireplace sizes.
3Volume of moving object
If a small circulating chamber is used, then the insert can be made compact, but strong electric blowers are required
Solution Approach 1:
By allowing the circulating chamber to be expanded to an optimal size through adjustable side walls, the system can maintain compactness when needed while providing sufficient volume for effective natural convection, thereby reducing or eliminating the need for high-power electric blowers.

AI summary
An adjustable circulating chamber for a fireplace insert having a rear wall including two linear sets of perforations forming two bendable side walls, and adapted such that the chamber can be adjusted to fit within fireplace inserts of differing dimensions and a top member including a linear set of perforations forming a flange portion thereon. The flange portion is adapted to be adjustably attached to the rear wall to thereby provide means to vary the height of the top member with respect to the rear wall. The top member further includes an oval-shaped opening therethrough and an adjustable flange member slidably mounted thereto and over the oval-shaped opening and having a circular opening therethrough, such that the oval-shaped opening and the adjustable flange member working together are adapted to receive, adjust, and fit fireplace flue pipes of differing dimensions to the fireplace insert.
