Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a laser beam mixer is used to convert bundle-type laser beam into single-type laser beam, then the conversion function is achieved, but precise alignment and distance control between lenses is required which increases device complexity and difficulty of operation
Solution Approach 1:
The optical cable jumper is designed to automatically align and transmit the laser beam without requiring external alignment tools or procedures. The built-in microlenses are pre-positioned to automatically focus and transmit the beam, making the system self-aligning and eliminating the need for complex alignment procedures by operators.
Solution Approach 2:
The optical cable jumper acts as an intermediary component between the bundle-type optical cable and the single-type optical cable. It contains built-in microlenses that mediate the beam transformation process, handling the complex optical alignment and focusing internally while presenting a simple connection interface to users.
2Measurement precision
If center alignment and distance control between lenses are implemented, then beam transmission accuracy is improved, but the setup time and operational complexity increase
Solution Approach 1:
The microlenses are pre-aligned and pre-positioned during manufacturing with high precision. The optical cable jumper is prepared in advance with the correct lens spacing and alignment, so that when deployed, it immediately provides accurate beam transmission without requiring field alignment or setup adjustments.
3Stability of the object's composition
If bundle-type optical cable is converted to single-type optical cable, then energy density uniformity is achieved, but the system requires complex lens alignment and distance control
Solution Approach 1:
The optical cable jumper merges the functions of multiple microlenses into a single integrated component. Instead of requiring separate alignment of multiple lenses, the jumper combines them into one unit that performs beam mixing, focusing, and transmission internally, simplifying the operation while maintaining energy density uniformity.
