Broadcast Receiver Segmentation for Slim Wall-Mount Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital broadcast receiving devices face limitations in slimness due to the inclusion of all constituent elements in one unit and installation restrictions when used as wall mount devices, particularly with the need for RF cables for signal reception.
Innovation Solution
A broadcast receiving device with a channel receiving unit and a main body unit separated, using serial-parallel converters to transmit and process broadcast signals, allowing for thinner designs and easier installation by separating signal processing components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If all constituent elements (channel receiving section, signal processing section, control section) are included in one unit, then the device can be compact, but the thickness of the device increases and installation flexibility is reduced
Solution Approach 1:
The broadcast receiving device is divided into two separate units: a channel receiving unit and a main body unit. The channel receiving unit contains the channel receiving section and serial-parallel converter, while the main body unit contains the signal processing section and control section. This segmentation allows the device to be thinner and more flexible for wall mounting while maintaining all necessary functions.
Solution Approach 2:
A serial-parallel converter is introduced as an intermediary component between the channel receiving unit and the main body unit. This converter enables signal transmission between the separated units through a thin connector, resolving the contradiction between device integration and thickness reduction.
2Device complexity
If all constituent elements are included in one unit, then signal processing is simplified, but installation becomes restricted due to RF cable requirements
Solution Approach 1:
By separating the channel receiving unit from the main body unit, the device can be installed in locations where wall mounting is desired. The segmented structure eliminates the need for RF cables to pass through the wall, as the channel receiving unit can be positioned near the signal source while the main body unit is mounted on the wall.
Solution Approach 2:
The serial-parallel converter acts as an intermediary that enables communication between the separated units through a thin connector, allowing flexible installation positions without requiring traditional RF cable routing through walls.
3Length of moving object
If the device is made thinner by separating units, then installation flexibility improves, but signal transmission between units becomes more challenging
Solution Approach 1:
The serial-parallel converter is designed as a reliable intermediary that converts parallel signals to serial signals for transmission through the thin connector between units. This conversion method ensures signal integrity is maintained despite the physical separation and thin connection medium.
Solution Approach 2:
The patent replaces traditional mechanical RF cable connections with an electrical serial-parallel conversion system that transmits signals through a thin connector. This substitution enables thinner device design while maintaining reliable signal transmission between separated units.
Data Source
AI summary
A broadcast receiving device and a method for receiving a broadcast thereof are provided. The broadcast receiving device includes a channel receiving unit which receives a channel broadcasting signal, generates a first parallel signal from the received channel broadcasting signal, converts the parallel signal into a serial signal, and outputs the serial signal; and a main body unit which receives the serial signal output from the channel receiving unit, reconverts the received serial signal into a second parallel signal, processes the second parallel signal, and outputs a video signal, an audio signal, and an additional data signal extracted from the processed second parallel signal. Since the channel receiving unit is provided as a separate unit from the main body unit, the thickness of the broadcast receiving device can be further reduced.
