Reusable Electronic Badge for Public Meeting Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic badges for public meetings require a new badge for each participant, leading to additional costs and waste, and do not allow participants to receive information about their access rights without querying a device.
Innovation Solution
An electronic badge with a display screen, internal memory, and ultra-high frequency communication capabilities, allowing it to interact with beacons positioned in different zones to provide personalized information and access control, eliminating the need for bulky readers and enabling data exchange and modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a new badge is created for each participant with permanently inscribed identity information, then the participant can identify themselves and display their identity, but this requires additional cost and generates waste for one-off events
Solution Approach 1:
The badge is designed as a universal device that can serve multiple participants across different events. Instead of being permanently inscribed with one participant's identity, the badge can have its identity information updated and reprogrammed for different users, making it a multi-functional tool that eliminates waste while maintaining reliable identity verification
Solution Approach 2:
The badge's identity information is changed dynamically through communication with beacons. The badge can switch between different identity parameters (participant ID, access rights, event information) based on signals received from beacons, allowing the same physical badge to serve different participants and purposes without physical replacement
2Ease of operation
If the electronic badge permanently displays participant identity information, then the participant can be visually identified, but this requires a new badge for each participant leading to additional costs
Solution Approach 1:
The badge functions as a universal identification device that can be assigned to any participant. The display shows identity information that is received dynamically from beacons rather than being permanently fixed, allowing one badge to serve multiple participants across different events while maintaining ease of visual identification
Solution Approach 2:
Instead of creating new physical badges for each participant, the system creates a digital copy of identity information that can be transferred to reusable badges. The badge displays a copy of the participant's identity data received from beacon signals, eliminating the need for physical badge multiplication
3Loss of information
If the electronic badge stores access right information permanently, then the participant can receive information about their right of access, but this requires querying a device rather than autonomous access
Solution Approach 1:
The badge receives and stores access right information from beacons in advance of when it is needed. By preliminarily acquiring this information through beacon communication, the badge has autonomous access capability without requiring real-time querying of external devices, improving ease of operation while maintaining information availability
Solution Approach 2:
The badge serves itself by autonomously storing and displaying access right information received from beacons. It does not require external querying devices to provide this information, as the badge independently manages its own information storage and display functions, making access information readily available to the participant
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a reusable, cost-effective, and waste-reducing badge that allows participants to access personalized information and access control autonomously, facilitating communication and reducing infrastructure costs while being adaptable to changing meeting conditions.
Implementation Method 1
The device also includes a transmitter, emitting an ultra-high frequency radio wave signal, preferably via Bluetooth
Implementation Method 2
The unit 12 also contains a receiver for ultra-high frequency radio waves, similar to those sent by the transmitter

AI summary
The communication method is intended for use during a public meeting. It comprises the following steps: - positioning of a mobile beacon (27) in an area (25), the beacon (27) emitting in said area (25) a signal specific to the area (25); - storage in a memory of each participant's badge (10) of an identifier and personal information of the participant, the badge (10) displaying some of the participant's personal information; - detection by the badge (10) of the signal emitted by the beacon (27); - when the badge (10) has detected the beacon (27), exchange of information between the beacon (27) and the badge (10), and/or display on the badge (10) of personal information relating to the area (25).
