Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire protection damper devices are costly to produce, difficult to maintain, and lack recyclability, while requiring fire sealing compounds that can damage structures during installation and removal.
Innovation Solution
A fire protection damper device with a duct body, movable damper blade, and elastic sealing member that allows for mounting without fire sealing compounds, enabling easy detachment and maintenance, and is designed to be compact and cost-effective with reduced material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fire sealing compounds are used to seal the mounting flange to the structure, then fire protection is improved, but the structure is damaged during installation and removal, and maintenance becomes difficult
Solution Approach 1:
The invention extracts and eliminates the fire sealing compound from the system by using an elastic sealing member that provides both sealing and fire protection functions inherently through its material properties and design, without requiring separate compounds that damage the structure
Solution Approach 2:
The mounting flange is designed as a separate component with an integrated elastic sealing member, allowing the damper device to be segmented into removable parts for easy maintenance while maintaining fire protection through the elastic sealing member that can be reused
2Reliability
If traditional fire protection dampers are designed with fixed mounting structures, then fire sealing is achieved, but the device becomes difficult to maintain and is not recyclable
Solution Approach 1:
The mounting flange with elastic sealing member provides a dynamic, reversible mounting solution that allows the damper device to be installed, removed, and reinstalled multiple times while maintaining fire sealing effectiveness, enabling maintenance and recyclability
Solution Approach 2:
The elastic sealing member changes its physical parameters (compression, expansion) during mounting and removal cycles while maintaining its fire protection properties, allowing repeated use without degradation of fire sealing capability
3Reliability
If fire sealing compounds are used during installation, then fire protection is ensured, but material is wasted and cost increases
Solution Approach 1:
The elastic sealing member is designed as a durable, reusable component that replaces disposable fire sealing compounds, eliminating material waste while maintaining fire protection across multiple installation and removal cycles
Solution Approach 2:
The invention recovers and reuses the elastic sealing member across multiple installations, eliminating the need to discard and replace fire sealing compounds with each installation, thereby reducing material waste and cost
