Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart TVs face challenges in implementing somatosensory system control and touch control functions due to cost and hardware constraints, making it difficult to utilize third-party developer applications that require gravity sensing and touch control.
Innovation Solution
A remote control method and system utilizing a Universal Plug and Play (UPnP) network to enable communication between a smart TV and a portable device, allowing the transmission of hardware information for operation control, which includes driver and control information, to perform operations similar to those in portable devices, such as single-touch or multi-touch controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a smart TV integrates touch screen and gravity sensor hardware, then touch control and gravity sensing functions can be implemented, but cost and hardware complexity increase significantly
Solution Approach 1:
The patent introduces a portable device as an intermediary between the user and the smart TV. The portable device contains the touch screen and gravity sensor hardware, while the smart TV provides the processing and display functions. This mediator approach allows the smart TV to access touch and gravity sensing capabilities without integrating the corresponding hardware, thereby resolving the contradiction between functional versatility and hardware complexity.
Solution Approach 2:
The patent enables the smart TV to perform multiple control functions (touch control, gravity sensing, direction sensing) by leveraging the portable device's hardware capabilities through network communication. The smart TV acts as a universal controller that can interface with various portable devices, providing multi-functional operation without requiring dedicated hardware for each function.
2Ease of operation
If a smart TV integrates touch screen and gravity sensor hardware, then somatosensory system control can be achieved, but manufacturing cost increases
Solution Approach 1:
The portable device serves as a cost-effective intermediary that provides somatosensory control hardware. Instead of the smart TV manufacturer investing in expensive touch screens and gravity sensors, the solution leverages existing portable devices that consumers already possess, thereby maintaining ease of operation while significantly reducing manufacturing costs.
Solution Approach 2:
The patent creates a virtual copy of the portable device's control hardware within the smart TV's software environment. Through UPnP network communication, the smart TV replicates the functionality of physical touch and gravity sensing hardware without actually incorporating the physical components, thus avoiding the associated manufacturing costs.
3Adaptability or versatility
If third-party developer applications require gravity sensing and touch control, then application functionality is enhanced, but implementation on smart TV becomes challenging due to hardware constraints
Solution Approach 1:
The portable device acts as a bridge that enables third-party applications designed for portable devices to run on smart TVs. The application executes on the portable device which provides the necessary gravity sensing and touch control hardware, while the smart TV displays the output. This intermediary approach maintains full application functionality without requiring the smart TV to meet the same hardware requirements.
Solution Approach 2:
The patent shifts the execution dimension from the smart TV's hardware to the portable device's hardware. Instead of requiring the smart TV to have gravity sensors and touch screens, the solution moves these hardware requirements to a different dimension (the portable device), allowing the smart TV to focus on processing and display functions while maintaining application compatibility.
