Rotatable TV Base for Wall Mounting and Sound Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing TV sets require time-consuming and laborious base mounting and removal processes, which can damage the base, and suffer from poor sound quality due to backward or downward sound generation, leading to dry sounds and reduced mid-range and treble sound reception.
Innovation Solution
A TV set design featuring a rotatable base with a triangular supporting structure that allows for easy switching between supporting and retracted states, incorporating a speaker assembly that generates sound towards the front, reducing base damage and improving sound quality by maintaining a thinner structure and enhancing sound wave transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the base is mounted and removed for wall hanging, then the TV set can be hung on a wall, but the mounting and removal procedures are time-consuming and laborious and the base is prone to damage
Solution Approach 1:
The base is designed as a dynamic structure that can rotate between a supporting state (for table top placement) and a retracted state (for wall hanging). The first and second members are rotatably connected, allowing the base to transform its configuration without removal, thus providing adaptability while maintaining ease of operation
Solution Approach 2:
The base serves multiple functions: it provides support when the TV is on a table top, and it can be rotated to a retracted position when the TV is mounted on a wall. This multi-functionality eliminates the need for separate mounting and removal procedures, resolving the contradiction between versatility and ease of operation
2Length of moving object
If the speaker assembly generates sound backwards or downwards, then the display screen assembly can be thinner, but the mid-range and treble sounds are reduced and sound quality becomes poor
Solution Approach 1:
The speaker assembly is mounted on the rotatable base, allowing it to dynamically adjust its sound generation direction. When the base is in the supporting state, the speaker can generate sound forward or downward, and when rotated to the retracted state, the sound direction changes accordingly, maintaining thin profile while improving sound quality through dynamic positioning
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design simplifies base adjustment, reduces damage, and improves sound quality by allowing the base to be easily switched between states without removal, and ensures better sound transmission by directing sound waves directly to the viewer.
Implementation Method 1
The at least one first member includes a first end and a supporting end, where the first end of the at least one first member is rotatably connected with a back side of the display screen assembly
Implementation Method 2
The second member includes a connecting end and a supporting end, wherein the connecting end of the second member is rotatably connected with the at least one first member at a rotatory connection point away from the first end of the at least one first member
Implementation Method 3
incorporating a speaker assembly that generates sound towards the front, reducing base damage and improving sound quality by maintaining a thinner structure and enhancing sound wave transmission

AI summary
In one aspect, a TV set is provided. A base includes a first member and a second member that have two supporting arms symmetrically disposed on two sides of the first member. One end of each of the two supporting arms is respectively rotatably connected with two side portions of the first member. When the base is in a supporting state, a first angle, a second angle and a third angle is formed between the first member and the display screen assembly, between the first and second members, and between the second member and a supporting object, respectively. When the base is in a retracted state, the first member is substantially parallel to the display screen assembly and is located at a lower portion of the display screen assembly, and the second member is located on a same side of the first member and the display screen assembly.
