Fire Protection System Ventilation Opening as Transport Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fire protection systems are becoming increasingly complex and heavy, making them difficult to lift and transport without compromising their structural integrity or fire protection approvals, which limits their portability and requires additional aids that may interfere with the system's construction.
Innovation Solution
Modifying ventilation openings to serve as transport brackets, allowing for improved force distribution and mechanical stabilization, enabling easier handling and transport without altering the system's design or approval status, and incorporating reinforcement materials like cement-reinforced or fiber-reinforced materials for enhanced stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fire protection systems are designed with increased complexity and higher fire resistance classes (up to F 180), then fire protection performance is improved, but weight increases to 700-800 kg for medium-sized housings and up to 1.5 t for free-standing housings
Solution Approach 1:
The ventilation opening is designed to serve dual purposes: its primary function for ventilation and its secondary function as a transport bracket. By modifying at least one opening side of the ventilation opening to create a transport bracket, the system eliminates the need for separate lifting aids while maintaining fire protection integrity. This multi-functionality directly addresses the weight issue by providing transport capability within the existing structure without adding external components.
2Ease of operation
If additional lifting aids are introduced to handle heavy fire protection systems, then ease of transport is improved, but device complexity increases and approval compliance may be jeopardized
Solution Approach 1:
The ventilation opening serves as both a ventilation component and a transport bracket, eliminating the need for separate lifting aids. This integration maintains the system's simplicity and preserves approval compliance while significantly improving ease of transport for heavy fire protection systems.
Solution Approach 2:
The transport function is merged with the ventilation opening structure. By forming a transport bracket from the opening sides of the ventilation opening, the patent combines two functions (ventilation and transport) into a single integrated component, reducing overall device complexity while improving handling capability.
3Ease of operation
If ventilation openings are modified to serve as transport brackets, then ease of transport is improved, but fire protection requirements may be compromised
Solution Approach 1:
The modification is applied locally to the opening sides of the ventilation opening rather than altering the entire structure. By forming transport brackets only at the opening sides and using reinforcement elements positioned strategically, the fire protection integrity of the main structure is preserved while providing transport capability where needed.
Solution Approach 2:
The patent employs reinforcement elements made of cement-reinforced and/or fiber-reinforced materials that are integrated with the existing wall material. These composite reinforcement elements maintain or enhance the fire protection properties while providing the necessary mechanical strength for transport operations.

AI summary
The invention relates to a fire protection system 1 which encloses a room on one or more sides, has a fire resistance of at least class EI30, and comprises at least one wall and/or a lockable building element with a ventilation opening 7 in the wall and/or building element. To make it easier to lift and carry the fire protection system, possibly even without additional aids, the geometry and surface of a ventilation opening 7 on at least one side of the opening are designed such that this area of the ventilation opening 7 serves as a transport support.
