Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed beam characteristic is used in background display devices, then the device structure is simple, but the adaptability to different recording situations is limited
Solution Approach 1:
The patent applies the dynamics principle by making the beam characteristic of the picture elements dynamically adjustable through a controllable lens arrangement. The lens arrangement can change the beam characteristic in response to different recording situations, transforming a static system into a dynamic one that adapts to varying requirements without requiring multiple fixed configurations.
Solution Approach 2:
The patent implements parameter changes by modifying the beam characteristic parameter of the picture elements through the lens arrangement. This allows the same physical device to operate with different beam characteristics (such as beam width, direction, or intensity distribution) depending on the recording situation, effectively changing the operational parameters without altering the physical structure.
2Productivity
If a fixed beam characteristic is used, then the device is easier to manufacture, but complex post-processing of recorded image material is required
Solution Approach 1:
The patent applies preliminary action by adjusting the beam characteristic of the picture elements in advance according to the specific recording situation. The lens arrangement pre-configures the optimal beam characteristics before recording begins, which eliminates the need for complex post-processing corrections and allows for direct capture of the desired image quality.
3Adaptability or versatility
If the beam characteristic is made variable, then the suitability for diverse recording situations is enhanced, but the control system becomes more complex
Solution Approach 1:
The patent introduces an intermediary lens arrangement between the picture elements and the recording medium. This lens arrangement acts as a mediator that simplifies the control complexity by providing a mechanical or optical interface for adjusting beam characteristics, rather than requiring complex electronic control of each picture element's light emission properties directly.
