Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Commercial aircraft curtains often hang loosely or stack unevenly when retracted, obstructing emergency exit locator signs and requiring significant manual adjustment, which can lead to safety and aesthetic issues, as well as increased workload for flight crew members.

Innovation Solution

An integrated magnetic slider assembly is introduced, featuring a slider portion, a hanger portion with integrated magnets, and a longitudinal hanging device, which aligns magnets to attract pleats together when the curtain is retracted, ensuring a neat stack and maintaining visibility of emergency exit signs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual adjustment is used to align curtains, then the curtains can be positioned correctly, but the workload and time required for flight crew members increases

Engineering Contradiction:

Improvecurtain alignment precisionVSAvoidtime for manual adjustment

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The curtain system uses magnetic attraction between magnets in the slider assembly and magnetic material in the curtain to automatically align and hold the curtain in the correct position during retraction, eliminating the need for manual adjustment by flight crew members while maintaining proper alignment precision

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical adjustment with a magnetic field-based system where magnets in the slider assembly attract to magnetic material in the curtain, creating automatic alignment and positioning without requiring human intervention

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If the curtain is allowed to retract freely, then the operation is simple, but the curtain hangs loosely and obstructs emergency exit locator signs

Engineering Contradiction:

Improvecurtain retraction operationVSAvoidemergency exit sign visibility

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The magnetic slider assembly automatically performs the function of aligning and stacking the curtain neatly during retraction without requiring manual intervention, ensuring the curtain does not hang loosely or obstruct emergency exit signs while maintaining simple operation

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The magnetic field acts as an intermediary force between the slider assembly and the curtain, creating attraction that pulls the curtain into proper alignment and stack configuration, preventing obstruction of emergency exit locator signs while maintaining ease of operation

Inventive Principle:

Principle #24Intermediary (Mediator)

3Extent of automation

If magnets are integrated into the slider assembly, then automatic stacking is achieved, but the device complexity increases

Engineering Contradiction:

Improveautomatic curtain stackingVSAvoidslider assembly structure

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The patent combines the slider assembly with magnetic components and integrates them into a single unit that attaches to the curtain rail, achieving automatic stacking functionality while managing device complexity through functional integration rather than separate components

Inventive Principle:

Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution allows for automatic, hands-free stacking of the curtain, preventing obstruction of emergency exit signs, reducing crew workload, and ensuring compliance with safety regulations by maintaining a clear view of essential signage.

AI summary

There is provided a system for an integrated magnetic slider assembly. The system has the integrated magnetic slider assembly with a slider portion, a hanger portion coupled to or integrated with the slider portion, and one or more magnets coupled to the hanger portion. The system further has a longitudinal hanging device configured for coupling to and suspending the slider portion of the integrated magnetic slider assembly. The system further has at least one hanging partition configured for coupling to the hanger portion of the integrated magnetic slider assembly, the at least one hanging partition having a plurality of pleats. All the magnets in a plurality of integrated magnetic slider assemblies are vertically aligned with respect to each other to cause a magnetic attraction between adjacent magnets in order to hold the plurality of pleats together, when the at least one hanging partition is in a retracted position.
