Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated systems such as robots are employed throughout the facility, then productivity and manufacturing precision are improved, but device complexity and initial costs increase making it cost prohibitive
Solution Approach 1:
The automated assembly system is divided into discrete modular workstations, each performing specific assembly tasks. This segmentation allows the facility to implement automation incrementally at individual stations rather than requiring a complete automated system, thereby reducing initial complexity and cost while still improving productivity at each modular unit.
Solution Approach 2:
The system employs dynamically reconfigurable modular workstations that can be adjusted and reconfigured based on production needs. This dynamic capability allows the automation system to adapt to different product designs and assembly requirements without requiring complete system replacement, managing complexity while maintaining high productivity.
2Device complexity
If manual assembly processes are used, then device complexity and initial costs are reduced, but contamination risks increase due to constant human involvement
Solution Approach 1:
Automated end effectors and robotic components serve as intermediaries between human operators and the electronic devices being assembled. This intermediary layer eliminates direct human contact with the devices during critical assembly operations, preventing contamination while keeping the overall system design relatively simple through the use of standardized automated components.
3Adaptability or versatility
If vast numbers of workers are employed for assembly, then adaptability to manual task variations is improved, but manufacturing costs increase due to rising labor costs and high worker turnover
Solution Approach 1:
The modular workstations are designed with universal components and standardized interfaces that can handle multiple assembly tasks and different device types. This multi-functionality allows a single automated system to adapt to various assembly requirements without requiring additional specialized equipment, thereby maintaining cost efficiency while preserving adaptability.
