Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of distributing travel-related information using conventional technologies limits its accessibility to locations beyond airports or specific terminals, due to expensive display and communication technologies.
Innovation Solution
A system comprising a display data management unit that formats and sends travel-related content to low-cost display units via a communication interface, supporting various data sources and formats, including arrival and departure information, maps, advertisements, and weather updates, using low-cost display technologies connected via wireless or wired networks, reducing bandwidth requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional display technologies are used to distribute travel information, then information accuracy and reliability are improved, but distribution cost and accessibility are worsened
Solution Approach 1:
The patent uses e-paper display technology that creates a visual copy of information similar to printed paper, allowing travel information to be displayed without requiring expensive conventional display hardware. This copying approach enables reliable information transmission at minimal cost, resolving the contradiction between information accuracy and distribution cost.
Solution Approach 2:
The patent employs low-cost e-paper display units that can be easily deployed and replaced, eliminating the need for expensive infrastructure. These disposable-like display units provide sufficient information display capability at a fraction of the cost of conventional displays, addressing the contradiction between reliability and distribution cost.
2Manufacturing precision
If expensive display technology is used to ensure high-quality information presentation, then information quality is improved, but device complexity and infrastructure requirements are worsened
Solution Approach 1:
The patent replaces complex expensive display infrastructure with simple e-paper display units that require minimal infrastructure. These low-cost displays maintain information quality while dramatically reducing device complexity and infrastructure requirements, allowing deployment in diverse locations without extensive technical support.
Solution Approach 2:
The patent extracts the essential information display function from complex conventional display systems, isolating the core capability to present travel information. This extraction allows the system to achieve information quality without the accompanying complexity of expensive hardware and infrastructure.
3Reliability
If conventional communication links are used to distribute travel data, then data transmission reliability is improved, but communication cost and bandwidth requirements are worsened
Solution Approach 1:
The e-paper display technology creates a static visual copy of information that can be transmitted efficiently over communication networks. This copying approach reduces the amount of data that needs to be continuously transmitted, maintaining transmission reliability while significantly reducing bandwidth requirements compared to conventional dynamic display systems.
Data Source
AI summary
A display data management unit that receives and formats data and sends the formatted data to one or more low-cost display units for display to at least one of passengers and customers is disclosed and may include a communication interface that facilitates the sending and receiving of travel data, and a display content management unit that receives travel data through the communication interface that contains travel-related content from one or more data sources, determines which travel-related content is to be displayed on each particular low-cost display unit, determines in what format the travel-related content is to be displayed on each particular low-cost display unit, formats the travel-related content for display, and sends the formatted travel-related content to one or more low-cost display units through the communication interface for display to one of passengers and customers.
