Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed nozzle is used in the shot treatment apparatus, then the device complexity is reduced, but the adaptability to different workpiece types deteriorates
Solution Approach 1:
The nozzle is made dynamically adjustable with positionable and three-dimensional swingable capabilities, allowing it to adapt its orientation and position according to different workpiece types and treatment requirements, thereby resolving the contradiction between device simplicity and adaptability
Solution Approach 2:
The nozzle system is designed to perform multiple functions by adjusting its position and orientation, enabling a single nozzle to handle various workpiece types and treatment patterns, thus improving versatility without proportionally increasing device complexity
2Manufacturing precision
If the nozzle position and rotation speed are manually adjusted for each product change, then the manufacturing precision is maintained, but the productivity deteriorates
Solution Approach 1:
The control apparatus automatically adjusts the nozzle position and swing parameters based on pre-stored work procedure information corresponding to different workpiece types, eliminating manual adjustment operations and enabling quick switching between product types while maintaining treatment precision
Solution Approach 2:
Work procedure information including optimal nozzle positions and swing parameters for different workpiece types is pre-stored in the control apparatus, allowing automatic selection and execution of appropriate parameters without manual intervention during production switching
3Productivity
If multiple spinning tables are provided on a revolving table, then the productivity is improved, but the device complexity increases
Solution Approach 1:
The workpiece processing system is segmented into multiple spinning tables arranged on a revolving table, allowing simultaneous processing of multiple workpieces at different stages (pretreatment, cleaning, installation/removal), thereby improving throughput while distributing the complexity across modular units
