Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated brake fluid filling is performed without independent verification, then filling speed and repeatability are improved, but the ability to diagnose malfunctions deteriorates
Solution Approach 1:
The patent creates a test vessel that replicates the brake system's pressure characteristics during air removal and fluid filling operations. By copying the pressure profile that would exist in an actual brake system, the test apparatus enables independent verification of the filling apparatus's sensor readings without requiring a real vehicle brake system, thus maintaining high productivity while improving diagnostic capability
Solution Approach 2:
The test vessel acts as an intermediary between the filling apparatus and the operator. It provides a controlled environment where pressure conditions can be precisely monitored by independent sensors, serving as a mediator that translates the filling apparatus's operations into measurable data for verification purposes
2Device complexity
If pressure monitoring is performed without independent verification, then system complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent segments the pressure monitoring function into two independent parts: the filling apparatus's sensor and the test vessel's sensor. This segmentation allows each sensor to perform its measurement independently, enabling verification of readings without significantly increasing overall system complexity, as the test vessel is a standalone component
Solution Approach 2:
The test vessel serves multiple functions: it simulates brake system pressure conditions, provides independent pressure monitoring, and enables verification of the filling apparatus's sensors. This multi-functionality allows precise measurement verification without adding separate dedicated equipment for each function
