Solution Overview

Problem

Display apparatuses require an IR receiver for initial pairing with control devices using near field communication methods like Bluetooth, limiting the use of Bluetooth-only control devices without an IR signal.

Innovation Solution

A display apparatus and method that allows Bluetooth pairing without an IR receiver, using a processor to search for connectable control devices, determine pairing history, and perform automatic booting and pairing when no history is found, enabling Bluetooth communication with a Bluetooth remote processor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a display apparatus uses an IR receiver for initial pairing with control devices, then pairing can be performed, but the device complexity increases and Bluetooth-only control devices cannot function

Engineering Contradiction:

Improvecompatibility with Bluetooth-only control devicesVSAvoidrequirement of IR receiver

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the booting function from the IR receiver and relocates it to the processor. The processor now performs the booting operation through logic implemented in software or firmware, eliminating the need for a separate IR receiver hardware component. This allows Bluetooth-only control devices to pair without requiring IR signal support.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the optical/mechanical IR signal transmission system with an electronic/software-based booting mechanism. Instead of using infrared light signals to boot the display apparatus, the processor directly executes booting logic when a control device is detected, substituting the physical IR communication layer with a software-controlled process.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If the display apparatus automatically boots when no pairing history is found, then pairing can be performed without IR signal, but power consumption increases

Engineering Contradiction:

Improveautomatic pairing capabilityVSAvoidpower consumption during booting

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent implements preliminary action by having the processor check pairing history before initiating the booting process. The system proactively determines whether pairing is needed by examining stored pairing information, and only boots when necessary (i.e., when no pairing history exists). This prevents unnecessary booting operations and associated power consumption.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses feedback mechanisms where the processor continuously monitors pairing history status and control device presence. Based on this feedback information, the system intelligently decides whether to initiate booting, creating a closed-loop control system that optimizes power consumption by avoiding redundant booting operations while ensuring pairing occurs when needed.

Inventive Principle:

Principle #23Feedback
