Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the laser source is replaced periodically, then the ultraviolet laser processing system can maintain operational capability, but the downtime increases and productivity decreases
Solution Approach 1:
The laser source is segmented into a modular assembly that includes the laser source, casing, electric connector, and fluidic connector as integrated components. This segmentation allows the entire assembly to be quickly replaced as a single unit, reducing downtime and maintaining productivity while ensuring the system retains operational capability.
2Duration of action of stationary object
If the laser source is replaced frequently, then the system can operate continuously, but the cost per process operation increases
Solution Approach 1:
The laser source is pre-assembled with its casing, electric connector, and fluidic connector into a complete replacement unit before being installed in the system. This preliminary assembly preparation eliminates the need for time-consuming on-site connections and adjustments, reducing the time and cost associated with frequent replacements while enabling continuous operation.
3Manufacturing precision
If the optical unit is tuned for each new laser source, then the processing precision is maintained, but the replacement time increases
Solution Approach 1:
The electric connector and fluidic connector are designed with adjustable parameters that can be modified to match different laser source characteristics. This allows the optical unit to be adapted to new laser sources without complete re-tuning, maintaining processing precision while significantly reducing the time required for replacement.
4Duration of action of moving object
If the laser source lifetime is extended, then the replacement frequency decreases, but the system complexity increases
Solution Approach 1:
The laser source is equipped with a casing and integrated connector system that is designed to accommodate gradual degradation and extended operation. This beforehand cushioning design allows the laser source to operate beyond its original lifetime without requiring complex system modifications, reducing replacement frequency while avoiding increased system complexity.
