Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for techniques to easily and intuitively manage voice and data communication among screenless communication devices that utilize wireless IP communication links, such as those used in IoT applications, where traditional smartphones may not be practical or economical.
Innovation Solution
The system employs a communication server that mediates voice and data communications among various endpoints, using multiple RF transceivers including WiFi, cellular, Bluetooth, and LoRa, and allows for peer-to-peer mesh configurations, enabling voice communication without the need for a display or internet access, with user interfaces based on voice recognition and visual indicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If screenless communication devices are used, then device complexity and cost are reduced, but ease of operation deteriorates due to lack of display interface
Solution Approach 1:
The patent introduces a companion application on a smartphone as an intermediary device to manage and control the screenless communication device. The companion app provides a graphical user interface that allows users to configure settings, monitor status, and manage communications without needing a display on the communication device itself. This mediator resolves the contradiction by transferring the operational interface to an external device.
Solution Approach 2:
The screenless communication device operates autonomously with voice recognition capabilities and automated response functions. The device can independently handle communications, recognize voice commands, and execute actions without requiring manual input through a display interface. This self-service capability compensates for the lack of display while maintaining ease of operation.
2Ease of operation
If voice recognition and visual indicators are used, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The screenless communication device integrates multiple communication technologies (WiFi, cellular, Bluetooth, LoRa) and interaction methods (voice recognition, visual indicators via LED rings) into a single universal platform. This multi-functionality allows the device to operate across different networks and communication modes while maintaining a consistent simplified interface, resolving the contradiction by consolidating complexity into integrated subsystems.
3Adaptability or versatility
If multiple RF transceivers are integrated, then adaptability and versatility are improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple RF transceiver technologies (WiFi, cellular, Bluetooth, LoRa) into a single integrated communication module within the screenless device. This merging approach allows the device to access multiple communication networks simultaneously while presenting a unified simplified interface to the user. The complexity of managing multiple transceivers is hidden within the integrated module, resolving the contradiction between versatility and simplicity.

AI summary
Techniques are disclosed for responding to a pre-recorded inbound voice message in a communication system that includes communication devices and a communication server. In a first communication device, a pre-recorded inbound voice message is received from a sender communication device via a communication server. A reply mode is set for a response voice message from a plurality of reply modes. The response voice message is recorded and a reply mode flag is inserted into a message header. The response voice message is then sent to the communication server where it determines the reply mode. When the reply mode is reply to all, the response voice message is sent to the sender communication device and other recipient communication devices. When the reply mode is reply to sender, a direct channel communication link is established between the first communication device and the sender communication device and the response voice message is sent directly to the sender communication device.
