RFID Voice Bulletin Board for Automatic Message Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional voice bulletin board systems require cumbersome user authentication procedures and lack efficient methods for automatically reproducing voice messages for receiving users, causing inconvenience and inefficiency in message retrieval.
Innovation Solution
A voice bulletin board apparatus using RF ID tags for non-contact authentication, where identity information is wirelessly transmitted and verified, allowing for automatic reproduction of voice messages when the intended receiving user is authenticated, eliminating the need for manual data entry and enabling seamless message delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a log-in system with manual identity information entry is used for user authentication, then user authentication can be performed, but the authentication procedure becomes complicated and inconvenient for users
Solution Approach 1:
The patent replaces the mechanical manual entry system with a wireless RF ID recognition system. The controller automatically reads identity information from the RF ID tag through wireless communication, eliminating the need for manual keyboard input and significantly simplifying the authentication process while maintaining security
Solution Approach 2:
The system enables self-service authentication where the user's identity is automatically recognized through the RF ID tag without requiring manual intervention. The controller autonomously completes the authentication process by comparing the read identity information with stored data, making the system serve itself rather than requiring user effort
2Loss of information
If the receiver user must manually find and select voice messages from multiple recorded messages, then the receiver can access messages, but the process becomes inconvenient and time-consuming
Solution Approach 1:
The system performs preliminary action by automatically reproducing the voice message before the receiver user even needs to request it. Once the controller identifies that the approaching user is the designated receiver, it immediately plays the recorded message, eliminating the need for the user to manually search or wait
Solution Approach 2:
The system provides self-service by automatically delivering the voice message to the receiver without requiring manual selection or retrieval actions. The controller autonomously completes the entire process from identification to message playback, saving the user time and effort
3Ease of operation
If the voice message is not automatically reproduced when the receiver passes by, then the system maintains control, but the receiver cannot actively and efficiently receive the message
Solution Approach 1:
The controller performs preliminary action by preparing to reproduce the voice message as soon as it detects the receiver's presence through RF ID recognition. The system proactively initiates message delivery rather than waiting for user commands, significantly improving delivery efficiency
Solution Approach 2:
The system uses feedback from the RF ID recognition to trigger automatic message reproduction. When the controller receives the identity information from the RF ID tag and confirms it matches the designated receiver, this feedback automatically initiates the voice message playback, creating an efficient responsive system
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
Simplifies user authentication and enables automatic voice message reproduction, enhancing user convenience and efficiency by allowing receiving users to access messages without additional operations, thereby improving the overall user experience.
Implementation Method 1
the tag wirelessly outputs the identity information in response to an RF (Radio Frequency) signal; and the identity information entry unit transmits the RF signal to the tag, and receives identity information from the tag
Data Source
AI summary
A voice bulletin board apparatus and a method for controlling the same. The voice bulletin board apparatus includes: a tag for storing identity information of a user of a voice bulletin board; an identity information entry unit for receiving the identity information from the tag according to a non-contact method; and a controller for receiving identity information of a recording user and/or a receiving user from the identity information entry unit, and authenticating the received identity information so as to record and/or reproduce a voice message. The apparatus reads identity information of the users according to a non-contact scheme, resulting in a simplified authentication process, automatically reproduces the recorded voice message regardless of message reproduction intention of the receiving user selected by the recording user, such that it can actively and efficiently provide the selected receiving user with the voice message of the recording user.
