Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wheel service machines measure wheel conditions and vehicle attitude parameters, then measurement precision is improved, but the tyre service person still lacks sufficient information to make precise adjustment decisions
Solution Approach 1:
The system measures wheel conditions and vehicle attitude parameters, then feeds back simulation results showing the effect of different adjustment options on on-road behavior. This closed-loop feedback provides the tyre service person with actionable information linking measurements to adjustment outcomes, resolving the information gap despite precise measurements.
Solution Approach 2:
A computer-based simulation system acts as an intermediary between measurement devices and the tyre service person. The simulation translates raw measurement data into predictive on-road behavior scenarios, providing the missing link between measurement precision and adjustment decision-making.
2Ease of operation
If the tyre service person adjusts vehicle configuration based on experience and approximations, then ease of operation is improved, but manufacturing precision of vehicle configuration deteriorates
Solution Approach 1:
The simulation system automatically calculates optimal adjustment configurations based on measured parameters, eliminating the need for the tyre service person to rely on experience-based approximations. The system serves itself by generating precise adjustment recommendations without human intervention in the calculation process.
Solution Approach 2:
The patent replaces the mechanical decision-making process (experience-based adjustment) with a computer-based simulation system. This substitution transitions from approximate human judgment to precise computational analysis, improving configuration precision while maintaining ease of operation through automated guidance.
3Productivity
If static adjustment is performed without simulating on-road behavior, then productivity is improved, but reliability of adjustment results deteriorates
Solution Approach 1:
The system performs preliminary simulation of on-road behavior before the actual adjustment is made. By predicting the effects of different adjustment configurations in advance, the system ensures reliable adjustment results while maintaining productivity, as the simulation is conducted computationally rather than through repeated trial adjustments.
Solution Approach 2:
The simulation creates a virtual copy of the vehicle's on-road behavior based on measured parameters and proposed adjustments. This digital twin allows prediction of adjustment outcomes without physical testing, ensuring reliability while preserving productivity by eliminating the need for multiple iterative adjustments.
