Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a tact switch is used to detect brake lever operation, then the brake operation can be detected, but the operation amount of the brake lever cannot be measured
Solution Approach 1:
The patent replaces the mechanical tact switch with a magnetic detection system consisting of a Hall IC sensor and magnet. This substitution enables continuous measurement of the brake lever operation amount through detection of magnetic field changes, transforming a binary on/off detection into a precise analog measurement system.
Solution Approach 2:
The patent changes the detection parameter from binary switch state to continuous magnetic field strength. By measuring the varying magnetic field intensity as the brake lever moves, the system can determine the operation amount proportionally, converting a qualitative detection into a quantitative measurement.
2Loss of information
If only binary operation detection is used, then the system is simple, but the information on traveling state is insufficient for smooth and safe traveling
Solution Approach 1:
The patent implements a feedback system where the detected operation amount is continuously transmitted to other vehicles and stored. This feedback loop provides real-time information about the current vehicle's operating state to surrounding vehicles and authorities, enabling improved traffic flow management and accident prevention.
Solution Approach 2:
The patent creates a multi-functional system that simultaneously performs operation detection, data storage, inter-vehicle communication, and accident reconstruction. The same detection mechanism serves multiple purposes: monitoring current operation, recording historical data, communicating with other vehicles, and providing evidence for accident analysis.
3Reliability
If detailed operation data is recorded and communicated, then driving safety and accident analysis are improved, but the system complexity and data processing requirements increase
Solution Approach 1:
The patent performs preliminary data collection and validation during normal operation, continuously monitoring and storing operation parameters before accidents occur. This preliminary action ensures that accurate data is already prepared and stored when needed for accident analysis, eliminating the need for complex post-accident data reconstruction.
