Fan Burner Mounting Device for Combustion Chamber Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forced-air burners require complex and heavy housing designs to absorb increasing forces and moments with higher air capacity, leading to increased design complexity and weight, and accessing modules between the burner and combustion chamber housing is difficult due to the need to swing the entire burner away, which complicates maintenance and operation.
Innovation Solution
A device with an attaching section for direct or indirect mounting to a combustion chamber housing, featuring a flange for interference fit and support arms to absorb forces and moments, allowing for a weight-optimized and easier-to-handle burner housing design, enabling partial opening of the housing for maintenance without needing to consider the entire system's mechanical strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the housing is designed as a whole to absorb forces and moments from the forced-air burner, then mechanical durability is improved, but design complexity and weight increase
Solution Approach 1:
The mounting system is divided into separate functional components: support arms that absorb forces and moments, and a housing that only needs to contain components. This segmentation allows each part to be optimized independently, reducing overall design complexity while maintaining mechanical durability.
Solution Approach 2:
The force-absorption function is extracted from the housing and transferred to dedicated support arms. The housing is relieved of the burden of absorbing forces and moments, allowing it to be designed as a lightweight containment structure rather than a heavy load-bearing component.

3Ease of operation
If hinges are used to swing the burner away for maintenance access, then accessibility is improved, but the hinges must sustain heavy forces and moments increasing device complexity
