Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single optical system structure is used, then the device complexity is reduced, but the dynamic light spot effect and usage performance deteriorate
Solution Approach 1:
The optical system is segmented into multiple independent reflective mirrors (first reflective mirror, second reflective mirror, third reflective mirror) mounted on separate motorized rotatable platforms. Each mirror can be independently controlled to rotate around its own axis, allowing the light beam to be directed in multiple directions and create dynamic spot effects that would be impossible with a single optical component.
Solution Approach 2:
The system transitions from a static optical structure to a dynamic one by equipping each reflective mirror with an independent motor (first motor, second motor, third motor) that enables continuous rotation. This allows the light spot to move dynamically across the stage and audience area, creating varied lighting effects and enhancing adaptability for different performance requirements.
2Adaptability or versatility
If multiple reflective mirrors with independent motors are added, then the dynamic light spot effect is improved, but the device complexity increases
Solution Approach 1:
Each motorized reflective mirror assembly serves multiple functions: the first reflective mirror controls horizontal light distribution, the second controls vertical angle adjustment, and the third provides additional directional control. This multi-functional design allows a single optical system to replace what would traditionally require multiple separate stage lighting fixtures, thereby managing complexity through functional integration.
Solution Approach 2:
The optical system employs a nested hierarchical control structure where three independent motorized mirror assemblies are integrated within a single unified optical platform. Each mirror assembly operates semi-independently but is coordinated through shared control systems, creating a nested architecture that manages complexity by organizing multiple moving parts within a cohesive structural framework.
