Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid suction systems require precise positioning of trolleys relative to cabin monuments, leading to potential noise emissions and complex handling processes.
Innovation Solution
A system comprising a hose with a flexible fluid line and adapter, allowing for easy coupling between the cabin monument and trolley without precise alignment, utilizing a controllable main fluid valve and triggering unit to establish a fluid connection and apply negative pressure for efficient fluid suction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed fluid connection is arranged on the cabin monument and a fixed fluid counter-connection is arranged on the trolley, then a fluid-tight connection can be established, but the trolley must be positioned particularly precisely in the receiving space to ensure the connection
Solution Approach 1:
The hose is made elastically and/or flexibly deformable, allowing it to adapt to different positions and orientations of the trolley. This dynamic flexibility replaces the rigid fixed connection, enabling fluid-tight coupling without precise positioning while maintaining connection reliability throughout the suction process
Solution Approach 2:
The hose's physical parameters (shape, length, orientation) are made changeable through elastic and/or flexible deformation. This allows the hose to compensate for positioning variations and maintain optimal connection conditions between the cabin monument and trolley without requiring precise initial positioning
2Object-generated harmful factors
If the trolley is fixed in the receiving space to maintain fluid-tight connection, then noise emissions are reduced, but the handling process becomes more complex
Solution Approach 1:
The flexible hose maintains continuous fluid-tight connection during trolley movement, eliminating the need to fix the trolley in place. This dynamic connection capability reduces noise emissions while keeping the handling process simple, as the trolley can be freely inserted and removed without complex fixing mechanisms
Solution Approach 2:
The flexible hose acts as an intermediary element between the fixed cabin monument and the movable trolley. It absorbs the mechanical constraints and maintains fluid connection stability, allowing the trolley to remain mobile (reducing noise) while ensuring reliable fluid coupling without complex handling procedures
3Ease of operation
If a hose with flexible fluid line and adapter is used, then simple coupling without precise positioning is enabled, but additional components are required
Solution Approach 1:
The hose assembly (comprising the flexible hose, adapter with trigger unit, and connector housing) serves multiple functions: it provides flexible fluid connection, enables simple coupling without precise positioning, incorporates control mechanisms for the main fluid valve, and ensures fluid-tight sealing. By combining these functions into a single integrated assembly, the system achieves operational simplicity without proportionally increasing overall system complexity
