Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If traditional incandescent or fluorescent lamps are used, then lighting function is provided, but lifespan is short and replacement frequency is high
Solution Approach 1:
The patent merges the controller, LED array, and connection terminals onto a single transparent substrate, eliminating the need for separate mounting structures and reducing assembly steps. This integration maintains the long lifespan benefit of LEDs while simplifying manufacturing processes and reducing overall device complexity
Solution Approach 2:
The transparent substrate serves multiple functions simultaneously: it acts as a mounting platform for the LED array and controller, provides electrical connection pathways, and functions as a light transmission medium. This multi-functionality reduces the number of separate components needed, lowering manufacturing costs while preserving LED longevity
2Duration of action of stationary object
If LED technology is adopted, then lifespan is extended and power consumption is reduced, but manufacturing cost increases
Solution Approach 1:
The controller is integrated directly onto the transparent substrate alongside the LED array, eliminating the need for separate controller housing and mounting hardware. This consolidation reduces component count and assembly complexity, making LED manufacturing more cost-effective while maintaining the technology's inherent lifespan advantages
Solution Approach 2:
The transparent substrate functions as a thin, multi-functional film that combines structural support, electrical connection, and light transmission properties. This approach replaces traditional bulky LED assemblies with a streamlined structure that is easier and cheaper to manufacture while preserving LED longevity
3Adaptability or versatility
If separate components are used for LED array and controller, then functionality is maintained, but device complexity increases
Solution Approach 1:
The controller and LED array are merged onto a single transparent substrate with integrated electrical connections. This integration maintains full control functionality while significantly reducing device complexity by eliminating separate mounting structures, wiring harnesses, and assembly steps
Solution Approach 2:
The patent transitions from a three-dimensional assembly of separate components to a two-dimensional integrated layout on the transparent substrate. This dimensional simplification reduces spatial complexity and assembly difficulty while preserving all necessary control functions through planar integration
