Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If specific devices are included within the light fixture to achieve scenographic effects, then the scenographic effects are enhanced, but the size and cost of the light fixture increase
Solution Approach 1:
The light source assembly is designed to perform multiple functions: it can rotate to create dynamic beam patterns, change colors through LED or laser diode sources, and project various forms using gobos. This multi-functionality eliminates the need for separate dedicated devices for each effect, thereby enhancing scenographic versatility while maintaining compact size and reasonable cost.
Solution Approach 2:
The patent combines the light source, rotation mechanism, color changing capability, and gobo projection into a single integrated light fixture. By merging these functions into one unit rather than using separate devices, the system achieves diverse scenographic effects without proportionally increasing size and cost.
2Adaptability or versatility
If the light source assembly rotates at high speed to exploit retinal persistence, then special scenographic effects are obtained, but the mechanical complexity increases
Solution Approach 1:
The light source assembly incorporates a rotation mechanism that enables dynamic movement at speeds of at least 25 rps. This dynamic capability allows the system to create special scenographic effects by exploiting retinal persistence, transforming a static light source into a dynamic effect generator without requiring complex mechanical systems.
3Adaptability or versatility
If multiple light sources and optical elements are used to create diverse beam forms and colors, then the scenographic versatility is improved, but the manufacturing cost increases
Solution Approach 1:
The light fixture uses LED or laser diode sources that can change color by altering electrical parameters rather than requiring separate physical light sources for each color. This parameter-based control allows diverse color combinations and beam forms to be achieved through electronic control, significantly reducing manufacturing cost compared to using multiple fixed-color light sources.
