Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in controlling multiple electronic devices due to the need for maintaining distance with remote controllers and limited versatility in input methods, especially with the increasing number of devices in home networks without remote control capabilities.
Innovation Solution
A mobile terminal with a short-range wireless communication module, memory unit, and display unit that registers external devices, transmits UI information, and performs operations based on user inputs through a touch screen interface, enabling seamless control of electronic devices like TVs, computers, and audio players.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional remote controllers are used to control electronic devices, then the user can operate the devices, but the user must maintain suitable distances and constantly search for the remote controller, reducing convenience
Solution Approach 1:
The mobile terminal serves as a universal remote control for multiple electronic devices (TV, audio device, computer) simultaneously. The control unit can identify and control different device types through their respective communication modules, eliminating the need for multiple dedicated remote controllers and reducing the time to find the appropriate remote.
Solution Approach 2:
The mobile terminal acts as an intermediary device between the user and electronic devices. It receives user inputs through the touch screen, processes control commands, and transmits them to the target electronic device via appropriate communication modules (short-range wireless or network communication), simplifying the control process.
2Adaptability or versatility
If traditional remote controllers with buttons are used, then the control method is simple, but the input methods are limited and versatility is reduced
Solution Approach 1:
The mobile terminal provides multiple input methods (touch screen gestures, keyboard input, mouse input) to control different types of electronic devices. The control unit adapts the interface based on the target device type, offering versatile control options while managing complexity through automated device identification.
Solution Approach 2:
The control interface dynamically adapts based on the identified electronic device type. The control unit adjusts the available control options and input methods according to the target device, providing appropriate versatility for each device while maintaining manageable complexity through context-aware interface adaptation.
3Adaptability or versatility
If multiple electronic devices are connected in a home network, then the system functionality increases, but the number of devices to control increases, making integrated control necessary
Solution Approach 1:
The mobile terminal serves as a centralized control hub for multiple electronic devices in the home network. It includes control functionality for TV, audio devices, computers, and other networked devices, allowing integrated control of the entire system through a single interface rather than requiring separate controllers for each device.
Solution Approach 2:
The mobile terminal acts as an intermediary that manages communication between the user and multiple electronic devices. The control unit identifies the target device, selects the appropriate communication module (short-range wireless or network communication), and handles the control signal transmission, simplifying the complexity of controlling multiple devices through automated device management.
