External Device Chat Mediator for Mobile Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices require manual activation of chat applications and interfaces to transmit and receive messages, which can consume power and limit convenience in chat processes, especially when interacting with external devices.
Innovation Solution
A method and system that allow a mobile device to perform a chat process using an external device paired with it, enabling message transmission and reception without activating the chat application on the mobile device, using a separate protocol signal and processing messages through the external device for output and input, thus reducing power consumption and enhancing independence from the mobile device's interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the chat application is activated on the mobile device to transmit and receive messages, then the chat function can be performed, but power consumption increases and user convenience decreases
Solution Approach 1:
The patent introduces an external device as an intermediary between the user and the mobile device's chat application. The external device captures user input (voice or text), processes it, and transmits it to the chat application through the mobile device without requiring the user to directly interact with the application interface. This mediator approach allows chat functionality while reducing the need to keep the application and interface active, thereby lowering power consumption.
Solution Approach 2:
The system performs preliminary actions by pre-processing user input on the external device before transmission to the mobile device. The external device prepares messages in advance (converting voice to text, formatting inputs), so that when the message is transmitted to the mobile device, minimal processing is required on the main device. This preliminary preparation reduces the operational burden and power consumption of the mobile device's chat application.
2Ease of operation
If the chat application and interface are activated on the mobile device, then message transmission and reception can occur, but manual interface manipulation is required which limits convenience
Solution Approach 1:
The external device provides self-service functionality by autonomously capturing user input through its own interface (microphone, display, buttons), processing the input locally, and automatically transmitting the processed message to the mobile device. The system serves itself by handling input capture and message preparation without requiring the user to manually navigate the mobile device's chat application interface, thereby increasing automation while maintaining ease of operation.
Solution Approach 2:
The external device acts as an intermediary that bridges the user and the mobile device's chat system. It absorbs the manual interface manipulation tasks (voice recording, text input, message composition) and handles them autonomously, then communicates only the essential message data to the mobile device. This intermediary layer automates the chat process while keeping the user experience simple and convenient.
3Reliability
If an open channel state is maintained with the external device for message transmission, then chat functionality is available, but power consumption increases
Solution Approach 1:
Instead of maintaining a continuous open channel state, the system uses periodic action by establishing communication channels only when needed for message transmission. The external device and mobile device connect, exchange messages, and then close or suspend the channel until the next communication need arises. This periodic activation maintains chat functionality availability while significantly reducing power consumption compared to continuous channel maintenance.

AI summary
Disclosed is a method, apparatus, system, and/or non-transitory computer readable medium for chatting on a mobile device using an external device. A chat method performed by a mobile device configured as a computer may include receiving a transmission input request for a signal including a send message through a preset button input of an external device; receiving, at the mobile device, the signal in response to the transmission input request; transmitting the send message to at least one counterpart that participates in a paired chatroom according to the signal; and outputting, to the external device, a received message that is received as a reply to the send message from the at least one counterpart through the chatroom.
