Solution Overview

Problem

Existing TV systems face significant signal degradation when the distance between the control box and the TV panel exceeds 30-50 centimeters, requiring the control box to be installed close to the panel or integrated on its back cover, which complicates wall mounting and increases the TV's thickness.

Innovation Solution

A display apparatus with a control device and a panel device connected via a transmission device that uses optical signals transmitted through optical fibers to minimize signal degradation, allowing the control device to be separated from the panel and mounted remotely, while power is supplied through pogo pins for efficient power transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the control box is externally connected to the panel via electrical cables, then the control box can be installed close to the panel, but signal degradation occurs when the cable length exceeds 30-50 centimeters

Engineering Contradiction:
Improvesignal qualityVSAvoidcable length
Core Design Contradiction:
ReliabilityVSLength of stationary object

Solution Approach 1:

The patent replaces electrical cable transmission with optical fiber transmission. The control box converts electrical signals to optical signals that are transmitted through optical fibers to the panel, eliminating signal degradation issues associated with long electrical cables while allowing greater installation flexibility.

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

Solution Approach 2:

The patent changes the transmission medium from electrical conductors to optical fibers, fundamentally altering the signal transmission parameter. This enables signal transmission over much longer distances without degradation, as optical fibers have significantly lower attenuation and interference compared to electrical cables.

Inventive Principle:
Principle #35Parameter changes

2Length of moving object

If the control box is integrated on the back cover of the panel, then the TV thickness is reduced, but the TV thickness becomes excessive due to the sum of control box and panel thickness

Engineering Contradiction:
ImproveTV thicknessVSAvoidintegration complexity
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The patent extracts the control box from the panel assembly, allowing it to be mounted separately on the wall or ceiling. The optical fiber connection enables the control box to be positioned independently from the panel, eliminating the need to accommodate its thickness within the panel's back cover structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent moves the control box from the same spatial plane as the panel (integrated on back cover) to a different spatial arrangement (separate wall or ceiling mounting). This dimensional repositioning allows the panel to maintain its original thickness while the control box occupies separate mounting space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If the control box is integrated on the back cover of the panel, then the TV structure is compact, but wall mounting becomes complicated requiring additional wall mount plate and shelf

Engineering Contradiction:
Improvewall mounting easeVSAvoidmounting structure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the control box from the panel integration, allowing it to be mounted independently using standard wall or ceiling mounting methods. This eliminates the need for complex integrated mounting structures and additional components like wall mount plates and shelves.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent enables the control box to serve multiple mounting locations (wall or ceiling) through its independent mounting capability. The optical fiber connection provides universal compatibility with various panel types and mounting configurations, simplifying the overall installation process.

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

AI summary

A display apparatus has a control device, a transmission device, a connection device, and a panel device. The control device receives a first data signal having a first signal type, and converts the first data signal to a second data signal having a second signal type different from the first signal type. The transmission device receives the second data signal, and converts the second data signal to a third data signal having a third signal type identical to the first signal type. The connection device removably coupled to the control device and the transmission device transmits the second data signal from the control device to the transmission device. The panel device removably coupled to the transmission device wirelessly receives the third data signal from the transmission device.
