Solution Overview

Problem

Existing display devices require a USB port for firmware updates, which is inconvenient and costly when the device lacks a reserved USB port, necessitating manufacturer intervention.

Innovation Solution

A setup method using a remote control device to transmit setting commands to a smart device, which converts and transmits display setting commands via a Display Data Channel (DDC) to the display device, allowing firmware updates and parameter adjustments without physical buttons or on-screen menus.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a USB port is provided for firmware updates, then firmware updating operation can be performed, but device complexity increases and production cost increases

Engineering Contradiction:
Improvefirmware updating operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The existing display connector is made to serve dual purposes: both video signal transmission and firmware update communication. By enabling the display connector to function as a USB communication interface for firmware updates, the system achieves multi-functionality without adding dedicated hardware, thus resolving the contradiction between ease of operation and device complexity

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

Solution Approach 2:

A smart device acts as an intermediary between the remote control device and the display device. The smart device receives firmware update commands from the remote control device and translates them into display setting commands that can be executed through the display connector's existing communication protocol, enabling firmware updates without requiring special USB ports on the display

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a reserved USB port is provided, then firmware updating operation can be performed independently, but device complexity increases

Engineering Contradiction:
Improvefirmware updating operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The display connector is designed to handle multiple functions including video input, audio output, and firmware update communication. By making the display connector universal for all these purposes, the system eliminates the need for a separate reserved USB port while maintaining independent firmware update capability

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

Solution Approach 2:

Instead of providing a dedicated physical USB port, the system creates a virtual USB interface through software/firmware on the display connector. This virtual interface copies the functionality of a physical USB port for communication purposes while avoiding the hardware complexity of adding actual USB components

Inventive Principle:
Principle #26Copying

3Ease of operation

If hardware buttons are provided for settings, then parameter adjustment can be performed, but production cost increases

Engineering Contradiction:
Improveparameter adjustmentVSAvoidproduction cost
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The patent replaces mechanical hardware buttons with a wireless control system. The remote control device communicates settings commands wirelessly through the display connector's communication interface, eliminating the need for physical buttons while maintaining parameter adjustment functionality. This substitution reduces manufacturing complexity and cost

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

Solution Approach 2:

The smart device serves as an intermediary that receives parameter adjustment commands from the remote control device and translates them into display setting commands. This intermediary approach allows parameter adjustment without requiring direct user interaction with hardware buttons on the display device

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A setup method of a display device includes the following steps. A remote control device transmits a setting command to a smart device through a transmission interface. The smart device converts the setting command into a display setting command. The smart device transmits the display setting command to the display device, in which a first connector of the smart device is physically connected to a second connector of the display device. The display device correspondingly performs a firmware update operation or correspondingly adjusts at least one parameter of the display device according to the display setting command.
