Fire Damper Frame Segmentation for Faster On-Site Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fire damper installation process is cumbersome due to a closed frame design that requires the housing to be pushed into a recess and then surrounded by plate segments, making it difficult and time-consuming to assemble and store.
Innovation Solution
The fire damper features a frame composed of multiple segments that can be easily assembled around the housing with non-overlapping end regions, secured by a separate fixing element, allowing for on-site assembly and storage of individual components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a closed frame design is used where the housing is pushed into a recess and then surrounded by plate segments, then the structural integrity of the fire damper is maintained, but the assembly process becomes cumbersome and time-consuming
Solution Approach 1:
The frame is divided into multiple frame segments (e.g., four segments for a rectangular frame) that can be assembled separately and then connected to form the complete frame. This segmentation allows the frame to be prepared in advance and assembled more quickly around the housing, reducing on-site assembly time while maintaining structural integrity through the connection of segments.
Solution Approach 2:
The frame segments can be pre-assembled or pre-positioned before the housing is installed. The recess can be prepared in advance by assembling the frame segments around the housing's intended position, allowing for faster final assembly when the housing is inserted, thereby reducing overall assembly time without compromising the structural integrity of the closed frame design.
2Reliability
If a closed frame design is used with plate segments attached around the housing, then the fire damper provides complete protection, but the installation process becomes difficult and complex
Solution Approach 1:
The frame is segmented into multiple sections that can be independently handled and assembled. This makes the installation process easier by allowing workers to assemble smaller, more manageable segments rather than dealing with a large, complex closed frame all at once, while still achieving complete protection when the segments are connected to form the full frame around the housing.
Solution Approach 2:
The frame segments are designed to be flexible in assembly, allowing for adjustment and adaptation during installation. The segments can be positioned and connected in different sequences or configurations depending on the specific installation context, making the installation process easier and more adaptable while maintaining the complete protective enclosure when assembled.
3Ease of manufacture
If the frame is designed as a single integrated piece, then the manufacturing process is simple, but the storage and handling become inefficient
Solution Approach 1:
The frame is divided into multiple segments that can be manufactured separately using simpler processes and then connected to form the complete frame. This segmentation improves storage efficiency by allowing the segments to be stored in a compact, disassembled state, reducing the volume required for storage and handling, while the manufacturing process remains simple through standardized segment production.

AI summary
The invention relates to a fire damper with a housing (1) for a shut-off damper (2) pivotably mounted therein about a pivot axis and with a mounting kit surrounding the housing (1) on the outside, wherein the mounting kit comprises at least one plate (4), preferably at least two plates (4) arranged adjacent to each other, wherein each plate (4) comprises at least two plate segments (4a) and is designed such that the entirety of all plate segments (4a) of the respective plate (4) forms a recess for receiving the housing (1), wherein each plate segment (4a) can be attached laterally from the outside, in particular in a radial direction, around the housing (1), and wherein the associated plate segments (4a) of each plate (4) contact the other plate segment(s) (4a) at two butt edges, wherein the housing (1) is further enclosed on the outside by at least one frame (5). To specify a fire damper,whose installation kit is easier and faster to assemble, each frame (5) shall comprise at least two frame segments (5a) and be designed such that the entirety of all frame segments (5a) of the respective frame (5) forms a recess for receiving the housing (1), wherein each frame segment (5a) can be attached laterally from the outside, in particular in a radial direction, around the housing (1),wherein the interacting end regions of two adjacent frame segments (5a) are provided adjacent to and in contact with each other without overlap in a direction orthogonal to the plane spanned by the frame segments (5a) of this frame (5), and wherein furthermore the interacting end regions of two adjacent frame segments (5a) are either directly fixed with respect to a relative movement to each other in at least one direction (8) or alternatively are indirectly fixed with respect to a relative movement to each other in at least one direction (8) by at least one separate fixing element, wherein each frame segment (5a) of two adjacent frame segments (5a) has in its respective end region, which interacts with the end region of the adjacent frame segment (5a), at least one insertion region (10) accessible laterally from the outside, preferably an insertion region (10) designed as an insertion opening,and that the two end regions of these two adjacent frame segments (5a) are fixed by at least one clamp (9) designed as a fixing element, which engages with one part into at least one insertion region (10) of one frame segment (5a) and with another part into at least one insertion region (10) of the other frame segment (5a).
