Solution Overview

Problem

Existing media delivery systems in transportation apparatuses face challenges in efficiently providing media content to passengers due to bandwidth limitations and the need for real-time wireless communication, which can be resource-intensive and technically challenging, especially during peak usage times.

Innovation Solution

A media delivery system that allows passengers to pre-select media content items before travel, which are then preloaded onto the transportation apparatus using off-peak network capacity, and enables authentication of user devices for seamless wireless access without requiring repeated login credentials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If media content items are delivered in real-time over wireless communication links during travel, then passengers can access content during travel, but the wireless communication link becomes heavily loaded and resource-intensive

Engineering Contradiction:
Improvecontent accessibilityVSAvoidwireless communication resources
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The system pre-loads media content items onto the transportation apparatus before the passenger's travel begins, using off-peak network capacity when wireless communication links have excess capacity. This preliminary action transfers content from remote servers to local storage in advance, so that during travel the content can be delivered locally without burdening the wireless communication link.

Inventive Principle:
Principle #10Preliminary action

2Loss of energy

If preloading is performed using off-peak network capacity, then wireless communication resources are optimized, but content delivery time is extended to before travel

Engineering Contradiction:
Improvewireless communication resourcesVSAvoidcontent delivery timing
Core Design Contradiction:
Loss of energyVSLoss of time

Solution Approach 1:

The system schedules content transfer during off-peak periods when network capacity is available, accepting that delivery occurs before travel. The system monitors network conditions and initiates transfers when excess capacity is detected, balancing the trade-off between using wireless resources efficiently and delivering content in a timely manner.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If authentication requires repeated login credentials, then security is maintained, but user convenience is reduced

Engineering Contradiction:
Improveauthentication securityVSAvoidaccess convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs authentication in advance by receiving credentials from the passenger's device before travel begins. The authenticated identity information is then stored locally on the transportation apparatus, enabling subsequent content access during travel without requiring repeated authentication. This preliminary authentication maintains security while improving convenience during the travel period.

Inventive Principle:
Principle #10Preliminary action

4Speed

If all media content is stored locally on the transportation apparatus, then real-time access is enabled, but storage capacity requirements increase

Engineering Contradiction:
Improvecontent delivery speedVSAvoidon-board storage capacity
Core Design Contradiction:
SpeedVSVolume of stationary object

Solution Approach 1:

The system selectively pre-loads only the specific media content items that the passenger has indicated interest in, rather than storing all available content locally. This approach maintains fast local delivery speed for requested content while minimizing the storage capacity required on the transportation apparatus.

Inventive Principle:
Principle #3Local quality

AI summary

Methods and systems for improved device authentication and presentation of media content to passengers aboard a transportation apparatus are disclosed. In some aspects, authentication of a device may be simplified based on previous associations made between the device, a user, and travel on a transportation apparatus within a particular time period. In some aspects, passenger selected media content may be prepositioned on stable storage within a transportation apparatus such that the media content may be provided to one or more passengers of the transportation apparatus while the transportation apparatus is in motion, and thus avoid transfer of the media content over an off-board wireless communication link.
