Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vein reader sensor is used for biometric verification, then reliability and speed of detection are improved, but the device requires a specific distance between sensor and hand which complicates integration into vehicle design
Solution Approach 1:
The patent combines the vein reader sensor with the shifter body by integrating the sensor into the grip portion, eliminating the need for a separate biometric verification device and simplifying overall system integration while maintaining reliable vein pattern detection
Solution Approach 2:
The patent creates a localized sensing chamber within the shifter body that provides the optimal detection environment for the vein reader sensor, allowing the sensor to function effectively at a fixed distance from the operator's palm without requiring complex external positioning mechanisms
2Ease of operation
If the vein reader sensor is positioned closer to reduce distance requirements, then ease of operation is improved, but measurement precision of vein patterns deteriorates
Solution Approach 1:
The patent optimizes the detection parameters by positioning the sensor at a specific distance (approximately 50mm) from the opening in the grip portion, and by providing a chamber that creates optimal optical conditions for vein pattern detection at this distance, thereby achieving both ease of operation and measurement precision
3Ease of operation
If the opening in the grip portion is made larger to improve hand access, then ease of operation is improved, but infrared radiation transparency may be compromised
Solution Approach 1:
The patent uses a transparent window made of infrared-transmissive material to cover the opening in the grip portion, allowing infrared radiation to pass through while providing a complete enclosure for the sensor chamber and maintaining proper optical conditions for vein pattern detection
