Solution Overview
Problem
Existing firestop collars are limited to specific opening cross sections, requiring either standard sizes that are not optimally configured or individually custom-made solutions, leading to inefficiencies in material usage and logistical challenges.
Innovation Solution
A modular firestop collar design featuring a frame constructed from common parts that can be configured using plug-type connectors, allowing for adaptation to various opening sizes, with a block of intumescent material securely fastened by front parts and optionally reinforced with an inner lining for enhanced stability and smoke gas imperviousness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standard sizes are used for firestop collars, then manufacturing and logistics are simplified, but the fit and optimization for specific opening cross sections deteriorates
Solution Approach 1:
The frame is divided into multiple modular frame parts that can be independently manufactured and then assembled together using plug-type connectors. This segmentation allows each component to be produced using standard manufacturing processes while the final assembled structure can be customized to fit various opening cross sections by selecting and combining appropriate frame parts.
Solution Approach 2:
The modular frame parts are designed with universal plug-type connectors that enable the same components to be used across different configurations and opening sizes. This universality allows a limited set of standardized frame parts to create multiple customized firestop collar solutions, achieving both manufacturing efficiency and adaptability.
2Adaptability or versatility
If individually configured firestop collars are made for each opening, then the fit to opening cross sections is optimized, but manufacturing complexity and logistics deteriorate
Solution Approach 1:
By segmenting the frame into standardized modular parts, the complexity of creating custom firestop collars is reduced. Instead of manufacturing entirely custom pieces for each opening, the system uses a library of pre-designed frame parts that can be assembled in different configurations, simplifying both manufacturing and on-site assembly.
Solution Approach 2:
The modular assembly system provides dynamic configurability, allowing the firestop collar structure to be adapted to different opening cross sections by simply reconfiguring the same set of frame parts. This dynamic approach eliminates the need for complex custom manufacturing while maintaining optimization for each specific application.
3Adaptability or versatility
If the frame is made from multiple non-modular parts, then customization is possible, but transportation and assembly efficiency deteriorate
Solution Approach 1:
The frame is segmented into modular parts that maintain configuration flexibility while enabling efficient assembly. The standardized segmentation allows for pre-fabrication and off-site preparation of frame components, which can then be rapidly assembled on-site using the plug-type connector system, improving both transportation efficiency and assembly speed.
Solution Approach 2:
The plug-type connectors serve as intermediaries between the frame parts, enabling rapid and tool-free assembly. These standardized connectors act as mediators that simplify the joining process, allowing workers to quickly assemble different frame configurations without requiring complex fastening operations, thereby improving assembly productivity.
