Solution Overview

Problem

Traditional tray tables in passenger vehicles often fail to stably support personal electronic devices (PEDs), leading to potential damage due to instability and the risk of devices falling during seat movements like taxiing, takeoff, and landing.

Innovation Solution

A tray table assembly with a holder assembly that includes a first holder pivotably attached to the tray table and a second holder pivotably attached to the first holder, allowing for movement between stowed and deployed positions, and folded and unfolded configurations, providing stable support for PEDs with adjustable height and positioning features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional PED holder is used in the tray table, then the holder can accommodate personal electronic devices, but the holder cannot stably support the PED and may allow the device to fall during seat movements

Engineering Contradiction:
Improvestability of PED supportVSAvoidholder structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The holder assembly is divided into multiple segments: a first holder portion pivotally attached to the tray table and a second holder portion pivotally attached to the first holder portion. This segmentation allows each portion to independently adjust and lock into position, providing stable support while maintaining a relatively simple overall structure. The segmented design enables the holder to adapt to different PED sizes and shapes without requiring a complex fixed structure.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the PED holder is fixed in position, then the structure is simple, but the holder cannot accommodate different types and sizes of PEDs

Engineering Contradiction:
Improveaccommodation of different PED typesVSAvoidholder structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The holder assembly incorporates pivotal connections that allow the first and second holder portions to rotate and adjust to different positions. This dynamic capability enables the holder to accommodate various PED types and sizes while maintaining structural simplicity. The pivotal joints provide controlled movement that can be locked into place, offering versatility without requiring a complex adjustable mechanism.

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the PED holder allows movement between stowed and deployed positions, then the ease of operation is improved, but the stability of the holder may be compromised

Engineering Contradiction:
Improvemovability of holder assemblyVSAvoidstability of holder in deployed position
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The holder assembly is designed with pivotal connections that inherently provide stability in both stowed and deployed positions. The first holder portion pivots relative to the tray table, and the second holder portion pivots relative to the first holder portion, allowing smooth transitions while maintaining secure positioning. This design cushiones the transition between states and ensures stability is maintained throughout the range of motion, not just at fixed endpoints.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
