Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mini LEDs are arranged in an array to display patterns, then various patterns or text can be displayed, but dark regions are formed between mini LEDs due to routing requirements, resulting in low resolution
Solution Approach 1:
The patent transitions from a two-dimensional array of mini LEDs to a three-dimensional structure by introducing a light guide plate positioned below the substrate. This allows light-emitting components to be placed in the gaps between mini LEDs at different vertical levels, filling the dark regions and enabling high-resolution display without compromising pattern variability.
Solution Approach 2:
The patent nests light-emitting components within the structural gaps of the mini LED array by positioning them on the light guide plate below the substrate. This nested arrangement allows additional light sources to occupy the routing spaces that would otherwise create dark regions, thereby improving resolution while maintaining the original mini LED pattern display capabilities.
2Shape
If a light-transmitting area with a light guide plate is used to emit a predetermined luminous pattern, then the appearance design is enhanced, but the pattern lacks variability
Solution Approach 1:
The patent makes the light guide plate serve multiple functions: it maintains the aesthetic light-transmitting appearance design while simultaneously housing additional light-emitting components that enable variable pattern display. The light guide plate acts as both a structural element for appearance and a functional platform for high-resolution pattern generation, eliminating the trade-off between design and versatility.
Solution Approach 2:
The patent merges the predetermined pattern emission function with the variable pattern display capability by integrating light-emitting components directly onto the light guide plate. This combination allows the system to achieve both the aesthetic appearance of a light-transmitting design and the flexibility of displaying various patterns and text through the additional light sources.
3Ease of manufacture
If routing requirements are considered for mini LED arrangement, then proper electrical connections are achieved, but gaps between mini LEDs create dark regions
Solution Approach 1:
The patent resolves the routing conflict by moving light-emitting components to a different vertical dimension on the light guide plate. This allows routing to proceed freely on the substrate level without creating visible dark regions, as the additional light sources are positioned below to fill the gaps between mini LEDs at the display level.
