Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If switching light guide components on a light transfer axis is used to achieve beam and pattern effects, then the stage lamp can switch between effects, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent combines the beam generating component and pattern generating component into a single integrated optical system where both components share the same light source and optical path. The beam component and pattern component are merged into one unified structure that can selectively activate either function, thereby reducing overall system complexity while maintaining versatility.
Solution Approach 2:
The optical system is designed with multi-functionality where a single light source and optical path serve dual purposes: generating both beam effects and pattern effects. The system can selectively activate either the beam component or pattern component based on operational requirements, making the same hardware structure versatile for multiple functions without requiring separate dedicated systems for each effect type.
2Adaptability or versatility
If switching positions of a light source is used to achieve beam and pattern effects, then the stage lamp can switch between effects, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent merges the beam generating component and pattern generating component into a single integrated optical system where both components share the same light source and optical path. This consolidation reduces the number of separate components that need to be manufactured and assembled, thereby lowering manufacturing costs while maintaining the ability to switch between effects.
Solution Approach 2:
The optical system is designed with multi-functionality where a single light source and optical path serve dual purposes: generating both beam effects and pattern effects. This universal design reduces manufacturing complexity and cost compared to having separate dedicated systems for each effect type.
3Adaptability or versatility
If switching between beam and pattern effects requires complex structural changes, then effect switching is possible, but operation becomes cumbersome
Solution Approach 1:
The patent implements a dynamic switching mechanism that allows rapid transition between beam and pattern effects without requiring physical reconfiguration of the optical system. The switching is achieved through electronic control of the light source activation, enabling fast and convenient effect changes during operation.
Solution Approach 2:
The optical system is designed with multi-functionality where a single light source and optical path serve dual purposes: generating both beam effects and pattern effects. This universal design simplifies operation because the system can switch between effects through simple activation control rather than complex mechanical reconfiguration.
