Engineering Contradiction Analysis
1Area of stationary object
If multiple independent displays are spliced together to form a large screen, then the screen size is increased, but physical gaps and height differences occur between adjacent displays
Solution Approach 1:
A connecting element is introduced as an intermediary component between adjacent backplanes. This connecting element includes a connecting surface with a geometric shape (e.g., 1/4 circular-arc convex surface) that complements the geometric surface (e.g., 1/4 circular-arc concave surface) on the backplane, enabling precise alignment and minimal spliced gaps when displays are assembled together.
Solution Approach 2:
The connecting surface and geometric surface employ curved geometries (specifically 1/4 circular-arc surfaces with matching radii of curvature) instead of flat surfaces. This curvature design enables better surface contact and alignment between adjacent displays, reducing spliced gaps and improving flatness when multiple displays are spliced together.
2Ease of manufacture
If displays are packaged independently, then manufacturing and assembly are simplified, but gaps and height differences occur after splicing
Solution Approach 1:
The display system is divided into independent display modules, each with its own backplane and connecting elements. This segmentation allows each display to be manufactured and packaged independently while maintaining the ability to achieve high flatness when assembled together through the connecting elements with complementary geometric surfaces.
Solution Approach 2:
The connecting element serves as a mediator that bridges independent backplanes. It includes a connecting surface with geometric features (e.g., 1/4 circular-arc convex surface) that complements the geometric surface on the backplane, ensuring that independent displays maintain high flatness when spliced together.
3Manufacturing precision
If connecting elements with complementary geometric surfaces are used, then spliced gaps are minimized, but assembly complexity increases
Solution Approach 1:
The connecting element and backplane feature simple curved geometries (1/4 circular-arc surfaces) that are easy to manufacture and assemble. The complementary curved surfaces naturally guide alignment during assembly, minimizing spliced gaps without requiring complex assembly mechanisms or procedures.
4Ease of operation
If magnetic materials are used for detachable assembly, then assembly and disassembly are simplified, but bonding force may be insufficient
Solution Approach 1:
The connecting element acts as an intermediary that provides both the geometric interface for precise alignment and the magnetic interface for detachable assembly. The geometric surfaces ensure proper positioning and minimal gaps, while the magnetic materials enable easy assembly and disassembly with sufficient bonding force.
