Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If members are used for a long period of time without frequent maintenance, then productivity is improved, but mounting accuracy deteriorates and member rank drops
Solution Approach 1:
The system performs preliminary evaluation of member status by calculating request member ranks based on board information and component information before actual mounting operations. This allows proactive identification of members that will soon deteriorate, enabling maintenance to be scheduled in advance before mounting accuracy actually drops, thus maintaining both high productivity and mounting accuracy.
Solution Approach 2:
The system establishes a feedback loop where mounting results and member performance data are continuously collected, evaluated, and used to update member ranks. This feedback mechanism allows the system to adapt maintenance schedules based on actual member performance, preventing accuracy deterioration while optimizing productivity by avoiding unnecessary maintenance.
2Manufacturing precision
If maintenance is performed frequently to maintain mounting accuracy, then mounting accuracy is improved, but productivity deteriorates due to increased maintenance time
Solution Approach 1:
The system changes the parameter of member evaluation from fixed time-based intervals to dynamic rank-based evaluation. By calculating request member ranks based on actual mounting board information, component characteristics, and member usage patterns, the system determines maintenance timing based on actual need rather than predetermined schedules, thereby maintaining accuracy while minimizing maintenance frequency.
Solution Approach 2:
The maintenance schedule becomes dynamic rather than static. The system continuously updates member ranks based on changing conditions including board types, component characteristics, and accumulated usage. This dynamic approach allows maintenance to be performed only when actually needed, adapting to real-time conditions to maintain accuracy without unnecessary productivity loss.
3Adaptability or versatility
If members are reused across multiple mounting machines, then resource utilization is improved, but it becomes difficult to manage member ranks and maintain consistent mounting accuracy
Solution Approach 1:
The system creates a universal member management framework that works across multiple mounting machines. By establishing a standardized method for calculating request member ranks based on board information and component information that is applicable to different machine types, the system enables consistent member evaluation and rank management regardless of which specific machine uses the member, thereby maintaining both versatility and reliability.
Solution Approach 2:
The request member rank calculation serves as an intermediary mechanism between diverse mounting machines and member management. This standardized evaluation process acts as a mediator that translates various machine-specific operations into a common rank assessment, enabling centralized management of members across multiple machines while maintaining consistent accuracy standards.
4Device complexity
If member rank evaluation is based on simple usage time, then evaluation process is simplified, but it does not accurately reflect actual mounting accuracy variations due to different usage situations
Solution Approach 1:
The system applies local quality by tailoring the member rank evaluation to specific local conditions including the particular board being mounted, the specific components involved, and the member's actual usage history with those items. Rather than applying a uniform time-based evaluation, the system customizes the evaluation based on relevant local factors, thereby achieving high measurement precision without requiring excessive overall system complexity.
