Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single electronic element is used to control emission intensity, then the control structure is simple, but the controllable intensity range is limited
Solution Approach 1:
The control function is segmented into two separate electronic elements, each responsible for a specific intensity range. The first electronic element controls the first intensity range while the second electronic element controls the second intensity range, allowing each element to be optimized for its specific range without being constrained by the need to handle the full range alone.
Solution Approach 2:
The solution transitions from a single-dimensional control approach (one element controlling all intensities) to a multi-dimensional control approach by introducing a second electronic element that operates independently in a different intensity dimension, thereby expanding the overall controllable intensity range.
2Adaptability or versatility
If emission intensity is controlled over a wide range, then the adaptability is improved, but flickering or stroboscopic effects occur
Solution Approach 1:
The wide intensity control range is segmented into two manageable ranges, each handled by a dedicated electronic element. This segmentation allows each element to operate within its optimal range without inducing flickering, while collectively providing wide-range control capability.
3Adaptability or versatility
If two electronic elements are used to extend intensity range, then the controllable intensity range is expanded, but the device complexity increases
Solution Approach 1:
The control system is segmented into two independent electronic elements, each handling a specific intensity range. This segmentation allows for modular design and independent optimization of each element while achieving the goal of extended intensity range control.
