Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If LED display tiles are assembled in close contact to minimize gaps, then the visual quality improves, but mechanical precision variations cause gaps and steps to become visible
Solution Approach 1:
The support structure includes adjustable positioning mechanisms that allow dynamic adjustment of each LED display tile's position. This enables compensation for manufacturing variations by dynamically adjusting the spacing and alignment of adjacent tiles to achieve consistent, inconspicuous gaps regardless of initial manufacturing tolerances.
Solution Approach 2:
The invention allows changing the positional parameters of LED display tiles through adjustable mounting mechanisms. By modifying the position, orientation, and spacing parameters of individual tiles during assembly and maintenance, the system achieves uniform gap sizes that minimize visibility despite variations in tile manufacturing precision.
2Ease of operation
If adjustment space is provided behind the video display device, then position adjustment becomes possible, but the device complexity and space requirements increase
Solution Approach 1:
The invention provides adjustment capability by utilizing the depth dimension (back-and-forth direction) in addition to the traditional horizontal and vertical adjustment dimensions. The pull-out mechanism extends the adjustment space into the depth direction, allowing position adjustments without requiring lateral workspace behind the display device.
Solution Approach 2:
The pull-out mechanism is nested within the support structure, with the video display device capable of being pulled out along the back-and-forth direction while remaining guided by the support structure. This nested configuration provides adjustment functionality without requiring external adjustment space.
3Stability of the object's composition
If the lock mechanism fastens the display device to the support structure, then stability improves, but adjustability deteriorates
Solution Approach 1:
The lock mechanism is designed as a dynamic system that can switch between locked and unlocked states. When unlocked, the pull-out mechanism allows movement for positioning adjustments. When locked, the mechanism provides stable fastening. This dynamic state change enables the system to alternately provide adjustability and stability as needed.
Solution Approach 2:
The lock mechanism acts as an intermediary between the desire for stability and the need for adjustability. By controlling the engagement state of the lock, the system mediates between these conflicting requirements, providing stability when locked and adjustability when unlocked, without requiring two separate systems.
4Measurement precision
If multiple adjustment mechanisms are provided, then positioning precision improves, but the device complexity increases
Solution Approach 1:
The support structure integrates multiple adjustment functions into a unified system. The pull-out mechanism simultaneously provides positioning in the back-and-forth direction and serves as a guide for horizontal and vertical alignment. The lock mechanism concurrently provides both stabilization and controlled release for adjustments, reducing the need for separate dedicated mechanisms for each function.
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
Enables precise adjustment and concealment of seams and steps between LED display tiles from both the display surface and backside directions, even without workable spaces behind, resulting in improved video image quality by minimizing visible gaps and variations.
Implementation Method 1
A magnet is disposed inside the step adjuster. A portion of the seam adjusting mechanism that abuts on the step adjuster is made of a magnetic material or magnet. When each of the plurality of video display devices is in the retraction position, the positioning pin is inserted in the cylindrical portion, so that a magnetic force causes the step adjuster to adhere to the seam adjusting mechanism

AI summary
An object is to provide a technique that enables making an adjustment from a direction where a video display surface is located, in order to provide inconspicuous seams between one of video display devices and other adjacent video display devices even when there are no workable spaces behind the video display devices. A multi-display system includes a plurality of LED display tiles, a position adjusting mechanism, and a pull-out mechanism. The position adjusting mechanism includes a lock mechanism that switches between a locking state and an unlocking state. When the lock mechanism is in the locking state, each of the LED display tiles is fastened in a retraction position. When the lock mechanism is in the unlocking state, each of the LED display tiles is movable between the retraction position and a pull-out position by the pull-out mechanism while being floated and supported via an elastic support portion.
