Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flat-screen display systems are cumbersome to install and transport due to complex and bulky support mechanisms, especially when transitioning between set-down and hanging positions.
Innovation Solution
A flat-screen display device with two mobile arms that fold during transport and unfold for stability on a horizontal plane, featuring rotation means with ball joints and synchronisation mechanisms, and integrated loudspeakers for improved ergonomics and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex support mechanism is used to enable transition between set-down and hanging positions, then the device can be mounted on wall or set down, but the device becomes cumbersome and requires complicated support structure
Solution Approach 1:
The support structure is divided into two separate mobile arms instead of one complex support mechanism. Each arm can independently transition between positions, simplifying the overall structure while maintaining the ability to support the screen in multiple configurations (set-down or wall-mounted positions).
Solution Approach 2:
The mobile arms are designed to be dynamic rather than fixed, allowing them to move between a first position (for set-down mounting) and a second position (for wall mounting or transport). This dynamic capability enables the screen to be easily reconfigured between different mounting positions without requiring complex fixed support structures.
2Ease of operation
If handles are added to enable carrying, then the device can be transported, but the device becomes cumbersome in both set-down position and carrying position
Solution Approach 1:
The mobile arms serve multiple functions: they provide structural support when the screen is in the set-down position and can be folded against the cabinet to enable easy carrying. This multi-functionality eliminates the need for separate handles, reducing overall device bulkiness while maintaining portability.
Solution Approach 2:
The mobile arms are designed to be dynamic rather than fixed, allowing them to move between a first position (for set-down mounting) and a second position (for wall mounting or transport). This dynamic capability enables the screen to be easily reconfigured between different mounting positions without requiring complex fixed support structures.
3Stability of the object's composition
If the arms are positioned for stability in set-down position, then the screen is stable, but the device occupies more space and is less compact
Solution Approach 1:
The mobile arms are designed to be dynamic rather than fixed, allowing them to move between a first position (for set-down mounting) and a second position (for wall mounting or transport). This dynamic capability enables the screen to be easily reconfigured between different mounting positions without requiring complex fixed support structures.
Solution Approach 2:
The mobile arms are extracted from the main cabinet body and positioned as separate, movable components. This allows them to be deployed when needed for stability during set-down operation and retracted into a compact configuration during transport, effectively separating the stability function from the compact form requirement.

AI summary
The invention concerns to a display device comprising a flat screen, a cabinet and at least one mobile arm capable of taking up first and second positions:in the first position, one end of the mobile arm or mobile arms is space apart from a plane corresponding to the front surface of the screen along a horizontal direction, one part at least of the arm or arms being adapted to maintain the screen in a noticeably vertical position when the device is resting on a horizontal plane, andin the second position, the arm(s) are in the space between the planes parallel to the screen and tangent respectively to the front and to the rear of the cabinet.
