Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional irradiation devices are designed to emit electromagnetic radiations at fixed beam angles, then the device structure is simple, but the adaptability is limited
Solution Approach 1:
The patent implements a movable lens assembly that can be positioned at different locations along the optical axis to change the beam angle dynamically. The lens assembly moves between a first location for a first beam angle and a second location for a second beam angle, enabling the device to adapt to different application requirements without requiring multiple fixed devices.
Solution Approach 2:
The irradiation device is designed with a single housing that can perform multiple functions by adjusting the lens position. The same housing and radiation source can produce different beam angles (first beam angle and second beam angle) by moving the lens assembly to different positions, making one device universal for multiple beam angle requirements.
2Adaptability or versatility
If devices allow different beam angles from within a single device, then the versatility is improved, but the device becomes bulky and cost-intensive
Solution Approach 1:
The optical system is segmented into a fixed lens and a movable lens assembly. The movable lens assembly can be positioned at different locations along the optical axis to achieve different beam angles. This segmentation allows the device to maintain a compact overall structure while providing variable beam angle capability through the movable component.
Solution Approach 2:
The movable lens assembly is nested within the housing and can move along the optical axis between different positions. The lens assembly is contained within the same housing that contains the radiation source, creating a compact integrated structure rather than requiring separate devices for different beam angles.
3Adaptability or versatility
If devices allow different beam angles from within a single device, then the versatility is improved, but the manufacturing cost increases significantly
Solution Approach 1:
The patent uses a dynamic lens positioning mechanism that can move the lens assembly to different locations along the optical axis. This dynamic adjustment capability is achieved through a relatively simple mechanical translation mechanism that can be manufactured cost-effectively compared to providing multiple separate fixed-angle devices.
Solution Approach 2:
A single housing and radiation source assembly serves multiple beam angle functions by moving the lens to different positions. This multi-functionality is achieved through a cost-effective design that uses one set of optical components (radiation source, housing) that can be manufactured once and used for multiple beam angle applications.
4Productivity
If the radiation source remains active during lens movement, then the operational continuity is maintained, but the system reliability decreases due to potential misalignment
Solution Approach 1:
The system is designed to deactivate the radiation source before moving the lens assembly to a new position and reactivate it only after the lens reaches the target position and is properly aligned. This preliminary action (deactivation) prevents potential misalignment issues during movement, ensuring that radiation is only emitted when the beam path is correctly configured.
