Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle driving assistant device is mounted in the vehicle, then the device can perform driving assistance functions, but installation errors or warpage cause inaccurate effective area determination
Solution Approach 1:
The patent applies preliminary action by measuring center axis values in multiple directions (first direction and second direction opposite to first direction) before final effective area determination. This preliminary measurement in multiple orientations allows the system to calculate gradient values and identify warpage errors in advance, enabling accurate effective area determination despite installation errors or warpage.
Solution Approach 2:
The patent implements feedback by using the sensor module to continuously measure center axis values and compare them against expected values. The control module calculates gradient values based on these measurements and uses the feedback to identify and correct for warpage errors, thereby maintaining accurate effective area determination throughout operation.
2Measurement precision
If the device requires service center visit for warpage correction, then accurate calibration can be achieved, but maintenance time and cost increase
Solution Approach 1:
The patent applies self-service by enabling the vehicle driving assistant device to automatically detect and correct its own warpage errors. The sensor module measures center axis values, the control module calculates gradient values and identifies warpage, and the system autonomously determines the corrected effective area without requiring external service center intervention, thereby reducing maintenance time and cost while maintaining calibration accuracy.
3Ease of operation
If the device autonomously corrects warpage on-site, then maintenance time and cost are reduced, but the complexity of the correction algorithm increases
Solution Approach 1:
The patent applies segmentation by dividing the warpage correction process into distinct segments: (1) measuring center axis values in multiple directions using the sensor module, (2) calculating gradient values from these measurements, (3) identifying warpage errors based on gradient analysis, and (4) determining the corrected effective area. This segmentation of the correction algorithm into manageable steps reduces overall system complexity while maintaining on-site correction capability.

AI summary
The present invention provides a vehicle driving assistant device, including: a sensor module; a camera module which photographs images; and a control module which calculates a gradient value of a ground where a vehicle is located based on a first center axis value measured by the sensor module when a front side of the vehicle is located in a first direction after being mounted and a second center axis value measured by the sensor module when the front side of the vehicle is located in a second direction which is opposite to the first direction and determines an effective area for following an object in the image based on a center axis fixing error value of the sensor module calculated using at least one of the first and second center axis values and the gradient value.
