Solution Overview

Problem

Conventional audio-visual devices require separate sound and image devices, leading to exposure of screens which cannot be protected and result in reduced viewer immersion due to aspect ratio issues and limited visibility of image-related sound outputs.

Innovation Solution

An audio-visual device with a display part that can appear and disappear, featuring a lifter mechanism allowing the display to be adjusted in height and accommodated within a housing, enabling it to function as both an image and sound device with adjustable aspect ratios and protection of the screen.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the display part is always exposed like conventional image devices, then the screen is visible for viewing, but the screen cannot be protected or hidden

Engineering Contradiction:
Improvescreen protectionVSAvoidscreen visibility
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The display part is designed to be movable between exposed and hidden positions through a lifting mechanism. The controller dynamically adjusts the display part position based on operational states, enabling the screen to be protected when not in use while remaining accessible for viewing during operation.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the screen displays images with aspect ratio 21:9 on a 16:9 screen, then more image content is shown, but black screens appear on upper and lower portions reducing viewer immersion

Engineering Contradiction:
Improveaspect ratio compatibilityVSAvoidviewer immersion
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The display part can be dynamically positioned at different heights to adjust the visible display area. When displaying 21:9 images, the system lifts the display part to eliminate black screens and provide full-screen coverage, enhancing viewer immersion while maintaining aspect ratio versatility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The solution adds vertical positioning as a new dimension for controlling the display area. By moving the display part vertically, the system can adjust which portions of the screen are visible, allowing full utilization of the display area for different aspect ratios without compromising immersion.

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

3Adaptability or versatility

If separate sound devices and image devices are manufactured, then each device can be optimized for its specific function, but the user needs to purchase and manage multiple devices

Engineering Contradiction:
Improvedevice functionalityVSAvoidnumber of devices
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines sound device and image device functions into a single integrated unit. The housing contains both the speaker unit and the display part with lifting mechanism, allowing the user to have one device that performs both audio and visual functions, reducing the number of separate devices needed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated device is designed to perform multiple functions: it can operate as a sound device with the display hidden, as an image device with the display exposed, and as both simultaneously. This multi-functionality allows a single device to replace what would traditionally require separate sound and image devices.

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

4Volume of moving object

If the screen size in sound devices is small, then the device can be compact, but the content can only be viewed when the user is close to the device

Engineering Contradiction:
Improvedevice compactnessVSAvoidviewing distance
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The display part can be dynamically extended outward from the housing when needed, increasing the effective viewing distance while maintaining a compact form when retracted. This allows users to view content from a greater distance when the display is extended, while the device remains compact when the display is retracted.

Inventive Principle:
Principle #15Dynamics
