Solution Overview

Problem

Current display devices require additional IR blaster functions for controlling peripheral devices, leading to increased costs and limited functionality, especially for users with visual impairments, as existing IR blaster functions often remain dormant due to battery issues and lack accurate feedback mechanisms.

Innovation Solution

A display device system that utilizes the IR blaster function equipped in a remote control device to control peripheral devices, enabling voice recognition for users to manage device states, thereby reducing costs and enhancing user convenience by providing accurate feedback through voice commands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an IR blaster function is applied to a remote control device, then the device can control peripheral devices, but the function remains dormant due to battery issues and cannot receive control commands from peripheral devices

Engineering Contradiction:
ImproveIR blaster functionalityVSAvoidcontinuous operation capability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent inverts the traditional IR communication architecture by enabling the remote control device to receive IR signals from peripheral devices, not just transmit them. This bidirectional capability allows the remote control to wake up from sleep mode and receive control commands from set-top boxes and other peripherals, solving the battery issue while maintaining full functionality

Inventive Principle:
Principle #13The other way round (Inversion)

2Ease of operation

If a multiple IR module is equipped to eliminate directivity restriction, then IR signal reception is improved, but the costs of products are increased

Engineering Contradiction:
ImproveIR signal reception reliabilityVSAvoidnumber of IR modules
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical solution of using multiple physical IR modules with an electronic/software-based solution. The display device uses its existing IR reception capability combined with voice recognition technology to detect and confirm IR signal reception, eliminating the need for multiple IR modules while maintaining reliable operation

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If voice recognition is implemented to provide feedback on device control, then user convenience is improved, but system complexity is increased

Engineering Contradiction:
Improveuser feedback capabilityVSAvoidvoice recognition system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent makes the display device's voice recognition system perform multiple functions: it not only recognizes user commands but also provides feedback confirmation when peripheral devices are successfully controlled via IR signals. This multi-functionality approach adds feedback capability without requiring a separate dedicated system

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An operating method of a display device is provided. The method includes: recognizing, by the display device, a user's function control voice for controlling a function of a peripheral device; controlling, by the display device, the peripheral device to perform a function corresponding to the recognized function control voice in the peripheral device through a remote control device; and providing, by the display device, a control state of the peripheral device representing that the function corresponding to the recognized function control voice is performed in the peripheral device.
