Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intercom systems face difficulties in quickly and conveniently registering wireless peripheral devices with access points, particularly when switching between different venues, due to slower wireless data protocols.
Innovation Solution
An intercom system with a user panel and wireless access point that utilizes short-range communication transceivers to establish connections, exchange identification information, and register devices based on matching characteristics such as bandwidth, connectivity strength, and UUID, enabling fast and convenient registration through Bluetooth Low Energy (BLE) connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional wireless data protocols are used for device registration, then devices can be registered wirelessly, but the registration process is slow and inconvenient
Solution Approach 1:
The patent segments the registration process into two distinct phases: (1) rapid pairing phase using Bluetooth Low Energy for quick device discovery and pairing, and (2) data transfer phase using Wi-Fi for actual profile transmission. This segmentation allows each protocol to be optimized for its specific function, with BLE providing fast initial connection and Wi-Fi handling bulk data transfer, thereby resolving the contradiction between wireless convenience and registration speed.
Solution Approach 2:
The patent introduces a mobile device as an intermediary that facilitates the registration process. The mobile device acts as a mediator between the wireless device and the access point, managing the pairing process through Bluetooth Low Energy and coordinating the transition to Wi-Fi for data transfer. This intermediary approach enables rapid device pairing while maintaining system coordination, effectively resolving the speed-time contradiction in device registration.
2Ease of operation
If wireless protocols are used for device registration, then device registration is possible, but the process is difficult and inconvenient when switching between venues
Solution Approach 1:
The patent implements universal device profiles that can be used across multiple venues and access points. The system stores standardized device profiles (such as headsets, microphones, and speakers) that can be quickly paired with any access point in the network. This universality allows users to seamlessly switch between venues without reconfiguring device settings, as the same profiles work across different locations, thereby resolving the contradiction between ease of operation and venue adaptability.
3Productivity
If fast registration is implemented using short-range communication, then registration speed improves, but additional transceivers and complexity are required
Solution Approach 1:
The patent merges two communication technologies (Bluetooth Low Energy and Wi-Fi) into a unified registration system. The access point and mobile device are configured with both BLE and Wi-Fi capabilities, allowing them to leverage the strengths of each protocol. BLE provides fast initial pairing while Wi-Fi handles data transfer, and the system automatically manages the transition between protocols. This merging approach increases productivity by enabling fast registration while the integrated design minimizes the perceived complexity for users.
Solution Approach 2:
The patent implements automatic protocol selection and transition management. The system automatically determines which protocol to use for each phase of registration and handles the transition between BLE and Wi-Fi without user intervention. The mobile device and access point self-coordinate to manage the pairing process, selecting the appropriate protocol based on the current task requirements. This self-service approach improves productivity while reducing the operational complexity users would otherwise need to manage.

AI summary
An intercom system including an intercom network, a user panel, and a wireless access point. The user panel includes a user panel wireless transceiver, a user panel short range communication transceiver, and a user panel electronic controller. The wireless access point communicatively coupled with the intercom network via a first intercom interface, the wireless access point includes an access point wireless transceiver, an access point short range communication transceiver, and an access point electronic controller. The access point electronic controller receives a user input to begin a registration mode, detects a first beacon signal via the access point short range communication transceiver, determines whether the user panel has matching characteristics with the wireless access point, initiates a first wireless connection between the access point short range communication transceiver and the user panel short range communication transceiver, exchanges identification information, and registers the user panel to the intercom network.
