Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If color devices are positioned downstream of the work point, then the light beam quality deteriorates and space for further elements is reduced, but the patent places color devices between the lamp and work point to resolve this
Solution Approach 1:
The patent inverts the conventional arrangement by placing color devices upstream of the work point rather than downstream. This inversion allows the color devices to be positioned in the space between the lamp and the work point, maintaining light beam quality while preserving space for other optical elements downstream of the work point.
Solution Approach 2:
The patent utilizes the spatial dimension between the lamp and the work point to accommodate color devices. By arranging color devices in this intermediate zone rather than downstream, the system optimizes space utilization and maintains optical quality without compromising either aspect.
2Ease of operation
If the fixture size is reduced to facilitate movement, then operator mobility improves, but space for components is minimized making integration difficult
Solution Approach 1:
The patent employs a nested arrangement where color devices are integrated within the compact space between the lamp and the work point. This nesting approach allows multiple functional elements to coexist in a reduced footprint, maintaining mobility while achieving complex optical effects.
Solution Approach 2:
The patent utilizes rotatable color devices that can dynamically adjust their orientation. This dynamic capability allows the compact fixture to achieve various optical effects without requiring additional fixed components, thereby maintaining small size while providing versatility.
3Adaptability or versatility
If color devices are made rotatable and inclined to optimize space and effects, then operational versatility improves, but device complexity increases
Solution Approach 1:
The patent designs color devices that serve multiple functions: they can rotate to different angles, be inclined to optimize space, and produce various optical effects. This multi-functionality reduces the need for separate components for each effect, thereby managing complexity while enhancing versatility.
Solution Approach 2:
The patent combines multiple color devices with rotational and inclination capabilities into an integrated assembly. By merging these functions into a single coherent structure, the system achieves diverse optical effects without proportionally increasing overall complexity.
