Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the laser module is moved frequently during processing, then the processing area coverage is improved, but the positional stability deteriorates leading to uncontrollable processing accuracy
Solution Approach 1:
The patent introduces a new degree of freedom by enabling independent movement of the focusing lens along the optical axis (Z-direction), separate from the laser module's position in the X-Y plane. This dimensional separation allows the laser module to maintain a fixed position while still achieving variable focal depths for different processing requirements, thereby maintaining processing accuracy while improving adaptability.
Solution Approach 2:
The patent segments the focusing function from the laser module positioning system. The focusing lens is made independently movable through a dedicated driving mechanism, separating the focusing degree of freedom from the module's positional movement. This segmentation allows independent optimization of positioning stability and focusing flexibility, resolving the contradiction between coverage and precision.
2Adaptability or versatility
If the focusing lens is made movable to adjust focal position, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The driving mechanism for the focusing lens is designed to serve multiple functions: it not only adjusts the focal position but also integrates with the existing laser module structure to provide stable mounting and alignment. This multi-functionality reduces the need for separate complex mechanisms, thereby achieving focal adjustment capability while minimizing additional structural complexity.
Solution Approach 2:
The patent merges the focusing lens driving mechanism with the existing laser module housing and mounting structure. The driving apparatus is integrated into the module's internal structure, sharing common components such as mounting brackets and alignment features, which reduces overall device complexity compared to having entirely separate focusing and positioning systems.
3Reliability
If the laser module structure is optimized for stability, then the reliability is improved, but the miniaturization capability deteriorates
Solution Approach 1:
The patent employs a nested structure where the focusing lens and its driving mechanism are housed within the existing laser module housing. The focusing apparatus is nested inside the module body, utilizing internal space efficiently. This nesting approach allows the addition of focusing functionality without significantly increasing the overall module volume, thereby enabling miniaturization while maintaining structural stability.
Solution Approach 2:
The patent introduces dynamic capability through the movable focusing lens while maintaining the static stability of the laser module housing and laser emitting apparatus. The dynamic focusing mechanism is designed with compact travel range and precise positioning, allowing focal adjustment without requiring large structural changes. This dynamic element is integrated into a stable, minimized housing structure, achieving both reliability and miniaturization.
