Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple welders are used to process different portions of a work, then machining versatility is improved, but device complexity increases due to need for multiple select mirrors and drive mechanisms
Solution Approach 1:
A single laser oscillator is designed to serve multiple welders (A-D) through selective beam direction. The laser oscillator performs multiple functions by directing its output to different welders based on processing needs, eliminating the requirement for multiple separate laser sources while maintaining machining versatility across different work portions.
Solution Approach 2:
Select mirrors (103-105) act as intermediary components that redirect the laser beam from a single laser oscillator to different welders. These mirrors serve as mediators that enable one laser source to serve multiple processing locations without requiring direct connection to each welder, thus reducing overall system complexity.
2Manufacturing precision
If the focal length of laser light is kept constant to maintain stable machining, then manufacturing precision is improved, but adaptability to different work distances deteriorates
Solution Approach 1:
The laser machining head is designed with movable optical components that allow dynamic adjustment of the focal length. This enables the system to adapt to different work distances while maintaining stable machining conditions for each specific configuration, combining both precision and adaptability.
Solution Approach 2:
The optical parameters of the laser machining head, particularly the focal length, are made changeable to suit different processing requirements and work distances. By allowing parameter adjustment, the system can optimize machining precision for each specific work configuration rather than being constrained to a fixed focal length.
3Adaptability or versatility
If select mirrors are moved to different positions to direct laser beam to different welders, then machining versatility is improved, but positioning accuracy requirements increase
Solution Approach 1:
Instead of requiring high-precision positioning of select mirrors, the system uses pre-calibrated mirror positions that have been optimized during setup. Once positioned correctly, the mirrors remain fixed at these calibrated locations, eliminating the need for continuous high-precision positioning while maintaining beam direction accuracy for versatile welding operations.
