Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If step motors are installed in hundreds of pixel cells to enable three-dimensional display, then stereoscopic display capability is improved, but parts cost increases to several tens of millions of won making commercialization nearly impossible
Solution Approach 1:
The patent replaces expensive step motors with a magnetic field-based driving system. A magnet is attached to the protruding portion and a magnetic sensor detects its position, eliminating the need for complex mechanical actuators in each pixel cell. This substitution dramatically reduces parts cost while maintaining stereoscopic display capability.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the control system and the display elements. Instead of direct mechanical actuation, the system uses magnetic fields to control the protruding portions, enabling precise positioning without expensive motors. The magnetic sensor acts as an intermediary detection mechanism.
2Ease of operation
If clutch method using electromagnet is used to control lifting and lowering screw, then movement control is simplified, but accumulated movement error occurs during continuous use making accurate stereoscopic image output impossible
Solution Approach 1:
The patent implements a feedback mechanism using a magnetic sensor that continuously detects the position of the magnet attached to the protruding portion. This feedback allows the system to accurately determine the current position and make precise adjustments, eliminating accumulated movement errors that occur with open-loop clutch mechanisms.
Solution Approach 2:
The patent replaces the mechanical clutch mechanism with a magnetic field-based positioning system. The magnetic sensor provides precise position detection without the mechanical wear and error accumulation inherent in clutch mechanisms, enabling continuous accurate operation.
3Adaptability or versatility
If fixed 3D model is used to represent three-dimensional objects, then three-dimensional representation is achieved, but characteristics such as size and direction become distorted and only information on a specific moment or state can be obtained
Solution Approach 1:
The patent creates a dynamic display system where individual pixel elements can protrude and retract to represent three-dimensional coordinates. This dynamic configuration allows accurate representation of spatial relationships, sizes, and directions by physically positioning elements in 3D space rather than using fixed projections that distort these characteristics.
Solution Approach 2:
The patent transitions from two-dimensional flat display to three-dimensional spatial display by enabling pixel elements to protrude from the screen plane. This addition of the z-dimension allows accurate representation of 3D coordinates, volumes, and spatial relationships without the distortions inherent in 2D projections.

AI summary
The purpose of the present invention is to provide a stereoscopic screen device having each pixel configured to protract/retract and method for controlling same, wherein stereoscopic information can be provided. Particularly, the present invention comprises: a fixed housing portion 100 coupled to a mainboard 10 having multiple slots 12 formed thereon, thereby forming each pixel cell of a stereoscopic screen, the fixed housing portion 100 containing a straight driving module 120, PCBs 112 mounted in the slots 12, and a distance sensing module 130; a protracting/retracting housing portion 200 installed to surround the fixed housing portion 100, coupled to the straight driving module 120 and moved accordingly, and configured to detect a distance of movement by the distance sensing module 130; and a visual information output portion 300 configured to output color data transmitted from a computer to the upper area of the protracting/retracting housing portion 200. The stereoscopic screen device having each pixel configured to protract/retract and a method for controlling same, if used, are advantageous in that it is possible to effectively provide visual stereoscopic information which is implemented in terms of x, y, and z axes, and which is dynamic, diversified, and stereoscopic, and the fixed housing portion and the protracting/retracting housing portion are modularized and assembled/installed in mainboard slots, thereby facilitating partial maintenance/repair in the case of malfunctions.
