Solution Overview

Problem

Existing aircraft cabin attendant seats lack a secure and reliable mechanism to store and retain mobile devices during flight conditions such as turbulence and emergencies, while allowing easy access and egress without interference.

Innovation Solution

A seat-mounted device holder with a main body, cover, lever assembly, and structural member that securely retains mobile devices within a cavity, featuring a retention lever assembly and padded portions to protect the device, capable of withstanding up to 16G acceleration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a device holder with retention lever assembly is implemented, then device security during turbulence is improved, but device accessibility is worsened

Engineering Contradiction:
Improvedevice securityVSAvoiddevice accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The retention lever assembly is designed to rotate between a first position (securing device) and a second position (releasing device). This dynamic mechanism allows the system to transition between secure retention and easy accessibility states, resolving the contradiction between device security and accessibility.

Inventive Principle:
Principle #15Dynamics

2Object-affected harmful factors

If a cover is added to enclose the device holder cavity, then device protection is improved, but device accessibility is worsened

Engineering Contradiction:
Improvedevice protectionVSAvoiddevice accessibility
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The cover is configured to rotate between a closed position (protecting device) and an open position (allowing access). This dynamic design enables the cover to provide protection when needed while allowing quick access when required, resolving the contradiction between protection and accessibility.

Inventive Principle:
Principle #15Dynamics

3Object-affected harmful factors

If padded portions are added to protect the mobile device, then device protection is improved, but device holder complexity is worsened

Engineering Contradiction:
Improvedevice protectionVSAvoidholder complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

Padded portions are strategically positioned within the device holder cavity at specific locations where devices may contact during turbulence. This localized approach provides necessary protection while minimizing the addition of components, thus reducing overall complexity compared to comprehensive padding.

Inventive Principle:
Principle #3Local quality

AI summary

A cabin attendant seat is disclosed. The seat may include a seat pan (602) and a seatback (604). The seat may include a device holder (100) coupled to the seat pan. The device holder may include a main body (102) including a plurality of main body walls (200) that define a main body cavity (202) and a cover (104) including a plurality of cover walls (300) that define a cover cavity (302). The main body cavity and the cover cavity may form a device holder cavity configured to stow a mobile device. The device holder may include an opening (112) configured to receive the mobile device. The device holder may include a device securing assembly (106) configured to rotate between a first and second position, when in the first position the securing assembly configured to secure the mobile device within the cavity, when in the second position the mobile device configured to be removed from the device holder cavity.
