Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If each pixel unit is equipped with complete light-emitting devices independently, then each pixel unit can function autonomously, but the total number of light-emitting devices increases leading to higher power consumption
Solution Approach 1:
Adjacent pixel units share common light-emitting devices (second and third light-emitting devices) located at their boundaries. Specifically, the first pixel unit and second pixel unit share one second light-emitting device and one third light-emitting device, while the third pixel unit and fourth pixel unit share another set of second and third light-emitting devices. This merging approach reduces the total number of light-emitting devices required while ensuring each pixel unit maintains its functional independence through the shared arrangement.
2Manufacturing precision
If light-emitting devices are densely arranged to improve display resolution, then display quality improves, but the complexity of circuit design and manufacturing increases
Solution Approach 1:
The second and third light-emitting devices serve multiple functions by being shared between adjacent pixel units. These shared devices contribute to the display output of multiple pixel units simultaneously, allowing a reduced number of devices to achieve the same or higher display resolution. This multi-functionality simplifies the overall circuit design and reduces manufacturing complexity while maintaining or improving display quality.
Solution Approach 2:
By merging the functionality of light-emitting devices across adjacent pixel units, the patent reduces the total device count and simplifies the circuit interconnections required. The shared light-emitting devices eliminate redundant circuit pathways, thereby reducing design complexity and manufacturing difficulty while achieving high display resolution through optimized spatial arrangement.
3Adaptability or versatility
If new circuit boards are designed for different pixel arrangements, then specific design requirements are met, but product development schedule is extended and labor cost increases
Solution Approach 1:
The circuit board design incorporates a universal layout where second and third light-emitting devices are positioned to be shared by multiple pixel units. This universal design can accommodate different pixel arrangements and display specifications without requiring complete redesign of the circuit board, thereby reducing development time and labor costs while maintaining adaptability to various display requirements.
