Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional alignment methods are used to position lens devices with respect to optoelectronic components, then precise positioning can be achieved, but the alignment process becomes costly and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-defining the distance between the adjustment lens and the optical element, and pre-positioning the lens device at an initial aligned position where the adjustment lens focuses the optical free-space beam. This preliminary positioning eliminates the need for time-consuming iterative adjustments during the alignment process, thereby reducing alignment time while maintaining precision.
Solution Approach 2:
The adjustment lens serves as an intermediary element in the alignment process. By using the adjustment lens to focus the optical free-space beam and establish an initial aligned position, the system creates a reference point that simplifies the subsequent positioning of the optical element. This intermediary mechanism enables more efficient alignment compared to direct positioning methods.
2Manufacturing precision
If traditional alignment methods are used to position lens devices with respect to optoelectronic components, then precise positioning can be achieved, but the alignment process becomes complex and costly
Solution Approach 1:
The patent reduces alignment process complexity by performing preliminary positioning actions: the lens device is pre-positioned at an initial aligned position where the adjustment lens focuses the optical free-space beam, and the distance between the adjustment lens and optical element is pre-defined. This eliminates the need for complex real-time adjustment mechanisms and simplifies the overall alignment procedure.
Solution Approach 2:
The adjustment lens acts as an intermediary that simplifies the alignment process. By establishing an initial aligned position through the adjustment lens's focusing action, the system creates a simplified reference framework that reduces the complexity of positioning the optical element relative to the access port, compared to direct alignment methods.
3Productivity
If the lens device is positioned to optimize light alignment, then data transmission efficiency is improved, but the positioning requires precise measurement and adjustment
Solution Approach 1:
The patent applies preliminary action by pre-defining the distance between the adjustment lens and the optical element, and pre-positioning the lens device at an initial aligned position. This preliminary setup provides a known reference framework that reduces the measurement precision requirements during final positioning, as the system only needs to adjust from a known good starting point rather than achieving absolute precision from scratch.

AI summary
A method of aligning a lens device includes: coupling an optical free-space beam that propagates along a first direction into an access port of an optoelectronic component, the first, a second, and a third direction being mutually perpendicular; positioning the lens device inside a free-space beam path, the lens device having an adjustment lens configured to focus radiation in only the second direction; moving the lens device along the second direction to align the adjustment lens with respect to the access port at an initial aligned position at which the optical free-space beam is one-dimensionally focused by the adjustment lens and at least a portion of a resulting one-dimensionally focused beam is input into the access port; and starting from the initial aligned position, moving the lens device in the second and/or third directions to position an optical element of the lens device in front of the access port.
