Mobile Terminal Event Signal Routing to Wearable Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals face limitations in call handling, particularly when users are engaged in phone calls, as they cannot easily perform other functions or access information from multiple terminals simultaneously without disrupting the call experience.
Innovation Solution
A mobile terminal system that allows for improved call handling by enabling the transmission of event signals between connected terminals, allowing information from one terminal to be displayed on another, even during active calls, through a network connection, using wireless communication units and controllers to manage multiple IDs and screen information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile terminal is used for phone calls, then call functionality is maintained, but the user cannot easily perform other functions or access information from multiple terminals simultaneously
Solution Approach 1:
The patent introduces a wearable device as an intermediary between the mobile terminal and the user. During phone calls, the wearable device displays information from multiple terminals simultaneously, allowing users to access information without interrupting the call on the mobile terminal. The wearable device acts as a mediator that receives data from the mobile terminal and presents it in an accessible format.
Solution Approach 2:
The patent utilizes the display screen of the wearable device as an additional dimension for information presentation. Instead of relying solely on the mobile terminal's display (which is occupied during calls), the system projects information to another dimension - the wearable device's screen - enabling simultaneous call handling and information access.
2Adaptability or versatility
If the terminal has a plurality of stored phone numbers, then communication versatility is improved, but the problem of managing and accessing information from multiple terminals becomes worse
Solution Approach 1:
The patent extracts the information management function from the mobile terminal during calls and transfers it to the wearable device. The wearable device displays information from multiple terminals simultaneously, allowing users to manage and access information from multiple sources without the complexity affecting the primary call function on the mobile terminal.
Solution Approach 2:
The patent segments the information display function from the call function. The mobile terminal handles calls while the wearable device handles information display from multiple terminals. This segmentation allows independent optimization of each function and reduces the complexity of managing multiple terminals within a single device interface.
3Loss of information
If the mobile terminal displays information during a call, then information accessibility is improved, but the call experience may be disrupted
Solution Approach 1:
The wearable device serves as an intermediary that handles information display during calls. By offloading the information display task to the wearable device, the mobile terminal can maintain focus on the call function without disruption, while users still gain access to information through the wearable device's display.
Solution Approach 2:
The patent moves information display to another dimension - the wearable device's screen - rather than displaying information on the mobile terminal during calls. This spatial separation allows information to be accessible without competing for the same display resources or potentially disrupting the call interface on the mobile terminal.

AI summary
A mobile terminal including a wireless communication unit configured to receive a call signal from at least one other terminal, in which the call signal corresponds to at least one of a first call ID and a second call ID of the mobile terminal; and a controller configured to receive an event on the mobile terminal after the call signal is received, transmit an event signal to an external terminal wirelessly connected with the mobile terminal using the corresponding first or second call ID to respond to the received event, and control the external terminal to display information on a display unit of the external terminal based on the event signal.
