Rooftop Landing Platform Sealing and Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing landing platforms lack adequate protection against media penetration, stability during assembly and operation, and secure connection of platform elements, which can lead to damage and failure under force or shock.
Innovation Solution
Incorporating a sealing arrangement between the connecting element and platform elements to create an impermeable landing surface, with multiple sealing areas and elements designed to prevent fluid penetration and enhance stability, including fire-resistant materials and anti-slip surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If platform elements are connected exclusively and directly via locking mechanisms, then assembly is simple, but the locking mechanisms can be damaged by force or impact, compromising the connection
Solution Approach 1:
The connection system is divided into three functional components: locking mechanisms for assembly, support elements for structural support, and sealing arrangements for protection. This segmentation allows each component to perform its specific function independently, preventing damage to locking mechanisms from direct impact forces.
Solution Approach 2:
Support elements and sealing arrangements act as intermediaries between platform elements. These intermediaries absorb and distribute forces, protecting the locking mechanisms from direct impact and preventing media penetration that could compromise connections.
2Ease of operation
If platform elements are connected using lugs or recesses forming click connections, then assembly is simple, but disassembly and replacement of individual elements can only be carried out from one direction or not non-destructively
Solution Approach 1:
The locking mechanisms are designed with reversible engagement characteristics, allowing the connection to be dynamically assembled and disassembled from either direction. The support elements can be independently removed without damaging the locking mechanisms, enabling non-destructive replacement of individual platform elements.
3Device complexity
If no sealing arrangement is provided, then the structure remains simple, but contaminated water, fire-fighting foam, or burning kerosene can penetrate the landing platform and cause damage below
Solution Approach 1:
Sealing arrangements incorporating flexible sealing elements are integrated into the connection between platform elements and support structures. These flexible seals prevent media penetration while maintaining structural simplicity and allowing for easy assembly and disassembly.
4Ease of operation
If the engagement depth of the connecting element is made small in the direction opposite to the height direction, then assembly from the landing surface is enabled, but the connection may be less stable
Solution Approach 1:
The connection stability is enhanced by adding dimensional components in multiple directions. Support elements extend in the height direction and lateral directions, creating a three-dimensional connection system that maintains stability even with reduced engagement depth in the opposite height direction.
Solution Approach 2:
The connection system uses composite structural elements combining locking mechanisms, support elements, and sealing arrangements. This composite approach distributes loads and forces across multiple materials and components, maintaining connection stability despite reduced engagement depth.
