Remote Control Device for Touch Application Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional TVs lack a touch control screen, preventing the execution of application programs designed for touch control, such as games, which are typically operated via touch control screens on devices like tablets and smartphones.
Innovation Solution
A remote control system comprising a remote control device with a touchpad input element, a control unit, and a wireless transmitter that generates and transmits absolute coordinate signals and motion signals to an electronic device, allowing the execution of touch-controlled application programs on devices without a touch screen by simulating cursor movements and command inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional TV without a touch control screen is used, then the device structure remains simple and cost-effective, but application programs designed for touch control (such as games) cannot be executed
Solution Approach 1:
A remote control device serves as an intermediary between the user and the TV. It includes a touch control pad that can execute touch-controlled application programs, and a wireless transmitter that sends control signals to the TV. This intermediary approach allows the TV to run touch-based applications without modifying the TV's physical structure, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The system is segmented into separate functional components: the remote control device handles touch control operations, while the TV handles display and reception. By dividing the functionality, the TV remains structurally simple while gaining the ability to run touch-controlled applications through the remote control's intermediary role.
2Adaptability or versatility
If a touch control screen is added to the TV, then application programs supporting touch control can be executed, but the device complexity and cost increase
Solution Approach 1:
Instead of modifying the TV with a touch control screen, a remote control device acts as an intermediary that provides the touch control functionality. The remote control includes a touch control pad and wireless transmitter, allowing it to execute touch-based applications and communicate with the TV without adding physical components to the TV itself.
Solution Approach 2:
The remote control device copies the touch control functionality needed for applications onto a separate device. By implementing the touch control pad and signal transmission capabilities in the remote control rather than the TV, the system achieves the same functional outcome without increasing the TV's structural complexity.
3Adaptability or versatility
If a remote control device with touch control pad is used, then touch-controlled application programs can be executed on the TV, but the ease of operation may be reduced due to additional devices
Solution Approach 1:
The remote control device is designed with multi-functionality, combining a touch control pad for executing applications, a wireless transmitter for sending control signals to the TV, and the capability to both receive and transmit signals. This universal design consolidates multiple functions into one device, maintaining ease of operation while enabling touch-controlled applications on the TV.

AI summary
A remote control system includes a remote control device and an electronic device. The remote control device includes an input element, a wireless transmitter to transmit an absolute coordinate signal and a motion signal and a control unit electrically connected to the input element and the wireless transmitter. The electronic device includes a wireless receiver and a display screen. The wireless receiver receives the absolute coordinate signal and the motion signal, and displays the absolute coordinate signal at the display screen via a cursor. When the electronic device does not receive the motion signal, the absolute coordinate signal is not operated on an application program of the electronic device. When the electronic device receives the motion signal, the absolute coordinate signal is operated on the application program.
