Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passive fire protection systems for cable trays are cumbersome, require destructive inspection, generate hazardous waste, and lose effectiveness over time, posing risks and inefficiencies in installation and maintenance.
Innovation Solution
A modular, removable fire protection device comprising a flexible mattress with endothermic and insulating materials, secured by removable fastening elements, allowing easy assembly, disassembly, and adaptation to cable tray configurations without permanent gluing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wrapping protection system is glued directly onto the cable tray, then fire protection is achieved, but the cables become invisible and cannot be inspected without destroying the wrapping
Solution Approach 1:
The protection system is divided into modular panels that can be independently removed and reinstalled, allowing cable inspection without complete destruction of the wrapping. Each panel can be detached to access cables and reattached to restore fire protection.
Solution Approach 2:
The protection system transitions from a static glued wrapping to a dynamic removable and reinstallable structure. The panels can be moved between attached and detached states, enabling flexible access for cable inspection while maintaining fire protection when needed.
2Ease of repair
If the wrapping is destroyed to add or inspect cables, then cable maintenance is possible, but hazardous waste is generated and installation risks increase
Solution Approach 1:
The protection system is segmented into removable panels that can be taken off and reinstalled, eliminating the need to destroy the wrapping for cable maintenance. This prevents generation of hazardous waste from destroyed fire protection materials.
Solution Approach 2:
Instead of discarding the wrapping when accessing cables, the panels are temporarily removed, used to access cables, then recovered and reinstalled. This recycles the fire protection material rather than generating waste.
3Reliability
If rigid and heavy protection systems are used, then fire protection performance is improved, but installation becomes difficult and time-consuming
Solution Approach 1:
The protection system is divided into smaller modular panels that can be handled and installed more easily than a single large rigid structure. This maintains fire protection performance while improving installation productivity through manageable sections.
Solution Approach 2:
The patent uses flexible fire protection panels instead of rigid heavy structures. These flexible panels achieve the required fire protection performance while being lighter and easier to install, directly addressing the productivity issue.
4Adaptability or versatility
If custom manufacturing is required for each cable tray, then fire protection adapts to specific geometries, but manufacturing complexity and time increase
Solution Approach 1:
The fire protection panels are designed with universal applicability to accommodate different cable tray geometries through standardized connection systems. This eliminates the need for custom manufacturing for each specific geometry while maintaining adaptability.
Solution Approach 2:
The modular panel system allows dynamic adaptation to different geometries through configuration of multiple standardized units rather than requiring custom-manufactured pieces for each specific geometry.
