Programmable Luggage Tag with Bistable Display and RFID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luggage tags are not integrated into airline baggage handling/management systems and are not reusable, resulting in significant waste as disposable machine-readable tags are used once and then discarded, contributing to environmental issues.
Innovation Solution
A programmable luggage tag featuring a bistable electronic visual display, radio frequency identification (RFID) transponder, and wireless reprogramming capabilities, allowing it to be reused and integrated into carriers' systems, with a design that includes a flexible microporous polymer core and a separate case for the display and RFID components to enhance durability and readability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If disposable machine readable tags are used for airline baggage handling, then integration with airline systems is achieved, but waste increases significantly
Solution Approach 1:
The patent implements a reusable RFID tag system where the tag is recovered and reused across multiple baggage handling cycles. The tag includes a reusable housing with display and RFID components that can be repeatedly applied to different bags, eliminating the need to discard disposable tags after single use.
Solution Approach 2:
The reusable tag is designed to serve multiple functions across different airline systems and baggage handling operations. The universal design allows the same tag hardware to be used with various airlines and baggage management systems, replacing the need for disposable single-use tags.
2Duration of action of stationary object
If permanent luggage tags with personal information are used, then reusability is achieved, but integration with machine readable airline systems is lost
Solution Approach 1:
The patent merges the permanent reusable tag design with machine-readable components by integrating an RFID transponder and display assembly into the housing. This combination allows the tag to simultaneously provide permanent personal information display and machine-readable data for airline system integration, resolving the trade-off between reusability and system integration.
Solution Approach 2:
The RFID transponder acts as an intermediary between the permanent tag housing and the airline's machine reading systems. It enables communication with airline baggage handling systems while the main housing and display remain as a permanent reusable component.
3Loss of information
If electronic display components are added to luggage tags, then information display capability is improved, but device complexity increases
Solution Approach 1:
The patent uses an electronic display to copy and present information from the RFID transponder and airline systems. Instead of requiring complex input mechanisms, the display copies information from existing data sources and presents it to the user, simplifying the overall system while improving information accessibility.
Solution Approach 2:
The electronic display automatically displays relevant baggage information without requiring manual input or complex user interaction. The system self-updates with new information from airline systems, reducing the need for complex user interfaces or manual data entry mechanisms.

Implementation Method 2
a bistable, programmable electronic visual display assembly including a display screen
Data Source
AI summary
A programmable luggage tag has a rigid, flat case containing a bistable visual display assembly, a BLE, NFC or other comparable short range, radio receiver and a processor configured to convert short range radio image control signals detected by the receiver into commands to modify the image on the display. A manual input switch on the case activates circuitry with a battery in the case for a time sufficient to receive the control signals and modify the image. A multilayer plastic, resiliently flexible thin flap is fixed with the case extending away from the case generally in a common plane with the case. The flap includes an encapsulated passive RFID transponder and mounting holes distal to the housing permitting the tag to be resiliently secured to the handle of a piece of luggage.
