Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If various optical elements and light modulators are combined to realize different modulation modes, then the versatility of the optical system is improved, but the device complexity and operational burden increase
Solution Approach 1:
The patent implements a sliding mechanism that enables dynamic reconfiguration of the optical path by allowing optical elements to be moved between different positions. This dynamic structure allows the same physical components to serve multiple functions depending on their arrangement, thereby achieving various modulation modes without requiring separate fixed optical paths for each mode.
Solution Approach 2:
The patent designs optical elements and light modulators that can perform multiple functions depending on their position in the optical path. The same components can be used for different modulation modes (e.g., intensity modulation, phase modulation, polarization modulation) by simply changing their arrangement through the sliding mechanism, eliminating the need for dedicated components for each modulation mode.
2Manufacturing precision
If optical elements are precisely arranged to achieve specific modulation modes, then the manufacturing precision is improved, but the ease of operation deteriorates when changing modes
Solution Approach 1:
The sliding mechanism provides a structured way to change the arrangement of optical elements from static to dynamic. Pre-defined sliding positions ensure that when elements are moved to specific locations, they automatically achieve the precise arrangement needed for the desired modulation mode, combining ease of operation with manufacturing precision.
Solution Approach 2:
The patent pre-establishes multiple discrete sliding positions along the optical path, each corresponding to a specific modulation mode. This preliminary arrangement of possible positions means that operators do not need to perform complex alignment procedures when switching modes; they simply move components to the pre-defined position corresponding to the desired mode, and the precise arrangement is automatically achieved.
3Adaptability or versatility
If the optical path is redesigned and elements are rearranged to change modulation modes, then the adaptability is improved, but the loss of time increases
Solution Approach 1:
The sliding mechanism transforms the time-consuming process of complete optical path redesign into a simple component repositioning operation. By maintaining the same physical components and only changing their positions along the predefined sliding path, the system achieves mode switching in a fraction of the time required for complete redesign and rearrangement.
Solution Approach 2:
The patent pre-establishes multiple discrete sliding positions along the optical path, each corresponding to a specific modulation mode. This preliminary arrangement of possible positions means that operators do not need to perform complex alignment procedures when switching modes; they simply move components to the pre-defined position corresponding to the desired mode, and the precise arrangement is automatically achieved.

The second wavelength selection surface is disposed at an angle at which the one beam incident in the positive direction of one of the first vector and the second vector is reflected in the positive direction of the other of the first vector and the second vector.
