Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dynamic vibration absorber is attached to suppress vibration, then vibration suppression effectiveness improves, but the complexity of determining optimal attachment position and type increases
Solution Approach 1:
The system performs preliminary measurement of vibration amplitudes at various positions on the work machine before finalizing the attachment configuration. By measuring and storing amplitude data in advance, the system determines optimal attachment positions and types beforehand, eliminating the need for complex real-time decision-making during operation.
Solution Approach 2:
The system displays measured vibration amplitude information and attachment position/type information on a display section, providing feedback to users about the vibration characteristics and optimal absorber configurations. This feedback mechanism guides users in making informed decisions about absorber placement without requiring complex analytical calculations.
2Device complexity
If dynamic vibration absorber attachment position and type are not optimized, then device simplicity is maintained, but vibration suppression effectiveness deteriorates
Solution Approach 1:
The work machine itself performs the measurement and information provision functions needed for optimal absorber attachment. The control section automatically measures vibration amplitudes, stores the data, and displays it to guide attachment decisions, eliminating the need for external complex measurement equipment or expert intervention.
3Device complexity
If vibration is not sufficiently suppressed, then no additional measurement or control systems are needed, but component mounting quality deteriorates
Solution Approach 1:
The system measures and identifies optimal vibration suppression configurations before component mounting operations begin. By determining and storing amplitude data and attachment information in advance, the system ensures that proper absorber attachment is established beforehand, preventing mounting quality issues without requiring complex real-time monitoring during the mounting process.
