Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If ultraviolet rays are widely applied inside a housing to produce optical shaped articles in multiple stages, then the desired shape can be achieved even if the printing surface is moved, but ultraviolet rays are applied to portions not needing light irradiation causing burden on human body and deterioration of goods quality
Solution Approach 1:
The patent applies light only to the specific region where the printing surface is located by using a sensor to detect the surface position and controlling the light source to illuminate only that area. This prevents unnecessary light exposure to other regions, thereby reducing adverse effects on the human body and goods while maintaining shape accuracy.
Solution Approach 2:
The patent employs a sensor to detect the actual position of the printing surface and feeds this information back to the control unit, which then adjusts the light source positioning accordingly. This feedback mechanism ensures that light is applied precisely where needed even when the surface moves, eliminating both shape errors and unnecessary light exposure.
2Adaptability or versatility
If printing surface is moved during production of optical shaped article in several stages, then production flexibility is improved, but it becomes difficult to produce the article in desired shape
Solution Approach 1:
The patent makes the light source positioning dynamic by using a sensor to detect the printing surface position in real-time and adjusting the light source location accordingly. This dynamic adjustment allows the system to adapt to surface movements during multi-stage production, maintaining shape accuracy while preserving production flexibility.
Solution Approach 2:
The sensor continuously monitors the printing surface position and provides feedback to the control unit, which adjusts the light source positioning in real-time. This feedback loop enables the system to compensate for surface movements during production, ensuring desired shape is achieved regardless of surface position changes.
