Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If service intervals are defined synchronously with vehicle service intervals for all components, then a standardized maintenance schedule is established, but maintenance costs increase due to unnecessary servicing of components with lower usage
Solution Approach 1:
The patent segments the maintenance monitoring by creating separate memory locations for different vehicle components (brake system components and non-brake components). Each component has its own total operating value stored independently, allowing differentiated maintenance scheduling based on actual usage of each specific component rather than a unified vehicle-wide schedule.
Solution Approach 2:
The patent changes the parameter basis for maintenance scheduling from fixed time-based intervals to usage-based total operating values. By storing and comparing actual operating data (switch-on times, switch-on frequencies) against limit values, the system adapts maintenance intervals to real component usage patterns, reducing unnecessary maintenance for low-usage components.
2Measurement precision
If separate monitoring systems are added for each vehicle component, then component-specific maintenance data is obtained, but device complexity increases significantly
Solution Approach 1:
The patent makes the electronic brake control device multi-functional by enabling it to monitor both brake system components and non-brake vehicle components through its existing output connections. The single control device stores total operating values for multiple different components in separate memory locations, eliminating the need for separate monitoring systems while achieving comprehensive component-specific monitoring.
Solution Approach 2:
The patent merges the monitoring function for multiple vehicle components into a single electronic brake control device. By combining the memory storage and evaluation capabilities within this one device, the system achieves component-specific monitoring without the complexity of multiple distributed monitoring systems.
3Reliability
If comprehensive operating data is collected for all vehicle components, then maintenance needs are accurately identified, but data processing and storage requirements increase
Solution Approach 1:
The patent extracts only the essential operating data needed for maintenance decisions - specifically total operating values (switch-on times and switch-on frequencies) for each component. Rather than storing all possible operational parameters, the system focuses on collecting and storing only these key metrics that directly indicate maintenance needs, reducing data storage requirements while maintaining reliable maintenance detection.
