Tablet Communication System with Automatic Display Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems require significant user effort and technical expertise to prepare multiple terminals for operation, including powering them up and setting destination addresses, which is burdensome and inefficient.
Innovation Solution
A communication system where a second terminal can transmit control information to a first terminal to initiate application execution and connect to a display device, allowing the first terminal to communicate and display information, even from a power-saving state, reducing the need for manual preparation and conserving power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminals are powered up and configured manually before operation, then communication readiness is achieved, but user burden and preparation time increase significantly
Solution Approach 1:
The terminal automatically performs communication setup and configuration when needed, without requiring manual user intervention. The terminal monitors for requests from external devices and autonomously establishes communication connections, making the system self-sufficient in preparation tasks.
Solution Approach 2:
The terminal maintains standby capability to receive communication requests even in power-saving mode, and pre-configures communication parameters automatically when a request is detected, eliminating the need for advance manual preparation by users.
2Speed
If terminals remain in normal operation state to ensure immediate responsiveness, then communication speed is improved, but power consumption increases
Solution Approach 1:
The terminal dynamically adjusts its operational state based on incoming requests. It can transition from a low-power standby state to an active communication state only when needed, optimizing the balance between responsiveness and power consumption by being adaptive rather than static.
Solution Approach 2:
The terminal periodically checks for communication requests in standby mode and activates full communication functionality only when a request is detected, rather than maintaining continuous high-power operation. This periodic monitoring approach reduces average power consumption while maintaining responsiveness.
3Reliability
If multiple terminals are configured with destination addresses manually, then communication routing is established, but setup complexity and time increase
Solution Approach 1:
The system introduces an external device or automatic identification mechanism that mediates the routing setup process. Instead of manual configuration, the terminal automatically identifies the destination device and establishes routing information through this intermediary process, eliminating time-consuming manual setup.
Solution Approach 2:
The terminal automatically configures its own destination address and routing information when a communication request is received, without requiring external manual configuration. The system performs self-configuration by extracting routing data from the request itself or through automatic device identification.
4Ease of operation
If the second terminal has high processing capability to manage multiple terminals, then system control is improved, but device cost and complexity increase
Solution Approach 1:
Each terminal in the system performs its own configuration and communication setup autonomously when requested, rather than relying on a powerful central controller to manage everything. This distributes the processing burden and allows simple terminals to function independently.
Solution Approach 2:
The external device or system acts as an intermediary that coordinates between terminals without requiring any single terminal to have high processing capability. The intermediary handles the coordination logic, allowing simple terminals to participate in complex multi-terminal operations.

AI summary
In a display system, one tablet terminal transmits control information to another tablet terminal. If the another tablet terminal receives the control information from the one tablet terminal, the another tablet terminal starts executing an application and starts communicating with a projector. The one tablet terminal transmits, to the projector, display instruction information instructing the another tablet terminal to display information. The projector receives the display instruction information from the one tablet terminal and transmits the display instruction information to the another tablet terminal currently connected to the projector. The another tablet terminal displays, on a touch panel, information designated by the display instruction information, if the another tablet terminal receives the display instruction information from the projector while executing the application.
