Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sphere is divided into two hemispheres and then each hemisphere is divided longitudinally according to multiple latitudes, then the spherical display screen can be constructed, but there will be end points that cannot be completely covered by LED modules, affecting display effect
Solution Approach 1:
The spherical display screen is segmented into multiple identical cabinet main frames, each with the same triangular structure. This segmentation allows the sphere to be constructed from repeating units, eliminating the need for special handling of end points and ensuring uniform coverage across the entire spherical surface.
Solution Approach 2:
The patent adopts a spherical geometric structure composed of triangular cabinet main frames. This spherical configuration allows the display surface to wrap around the sphere uniformly, eliminating flat surface end points and ensuring continuous LED coverage across the curved surface.
2Reliability
If each hemisphere is divided into curved triangles with different shapes, then the spherical display screen can be formed, but the design cost and difficulty of installation are greatly increased
Solution Approach 1:
Each cabinet main frame is designed with identical local quality - the same triangular structure, same LED module arrangement, and same magnetic connection configuration. This uniformity in local quality across all segments simplifies manufacturing and installation, as each unit can be produced and installed using the same procedures.
Solution Approach 2:
The patent employs homogeneous cabinet main frames throughout the spherical structure. All triangular units are identical in shape, size, and configuration, ensuring uniform appearance and consistent performance across the entire display. This homogeneity eliminates the need for different designs for different positions, reducing both design cost and installation complexity.
3Reliability
If traditional spherical cabinet structures are used, then the display screen can be assembled, but the end points affect the display effect and the structure is complex
Solution Approach 1:
The spherical cabinet is segmented into multiple identical triangular main frames, each capable of independent assembly. This segmentation eliminates the need for complex end point handling, as each segment follows the same structural pattern and connects uniformly to its neighbors through magnetic joints.
Solution Approach 2:
The patent replaces traditional mechanical fastening systems with magnetic connection between cabinet main frames and LED modules. This substitution simplifies the assembly process, eliminates complex mechanical joints at end points, and allows for easier installation and maintenance while maintaining structural integrity.

AI summary
An icosahedral LED display screen belongs to the field of display screens and includes multiple cabinet main frames. Each cabinet main frame is formed with an accommodating cavity. A side of each cabinet main frame is provided with a flexible PCB, an outer side of the flexible PCB is disposed with LEDs, and an inner side of the flexible PCB is provided with a magnet fixedly therewith. The multiple e.g., twenty cabinet main frames are mutually connected to form an icosahedral sphere which has no end point similar to a football, and polygons that make up the sphere are the same, and therefore the cabinet main frames can be completely covered by the flexible PCBs to eliminate a missing of display at an endpoint and reduce design numbers and complexities of the cabinet main frames and the flexible PCBs. An installation of the LED display screen becomes more convenient.
