Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the work system uses basic attachment parameter storage for configuration evaluation, then the system structure remains simple, but the evaluation precision and optimization accuracy are insufficient
Solution Approach 1:
The patent transforms the evaluation approach from storing basic attachment parameters to calculating dynamic device interface loads based on attachment configurations. This parameter transformation enables precise evaluation of machine configuration effects (such as ballast and tire pressure) by quantifying the actual mechanical loads transmitted through attachment interfaces, thereby resolving the contradiction between evaluation precision and system complexity.
2Productivity
If the system calculates device interface load based on attachment configuration, then the optimization accuracy improves, but the calculation complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-storing device interface load characteristics and calculation models for different attachment configurations in the control arrangement. When evaluating machine configurations, the system retrieves and combines these pre-stored data with current operating parameters, avoiding complex real-time calculations while achieving accurate load assessment and optimization.
3Duration of action of stationary object
If the system evaluates machine configuration without considering device interface load, then the system operation remains simple, but the service life optimization and fuel efficiency improvement are limited
Solution Approach 1:
The patent implements feedback by continuously monitoring attachment configurations and calculating the resulting device interface loads, which are then fed back to evaluate and optimize machine configurations (such as ballast distribution and tire pressure settings). This closed-loop feedback mechanism enables the system to adjust configurations to minimize mechanical stresses on critical components, thereby extending service life while improving fuel efficiency without excessive complexity.
