Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are mounted on the vehicle body to advance driving support technology, then detection capability is improved, but space utilization efficiency deteriorates
Solution Approach 1:
The patent combines multiple sensor units (first sensor unit and second sensor unit) into a single integrated sensor system mounted on the vehicle body. By merging multiple sensors into one coordinated system with intersecting detecting reference axes, the patent achieves comprehensive detection capability while optimizing space utilization, as the sensors share a common mounting structure and coordination mechanism rather than requiring separate mounting spaces.
2Measurement precision
If multiple sensors are arranged to improve detection capability, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent creates a multi-functional sensor system where the first sensor unit and second sensor unit work together to provide comprehensive detection capabilities. The system achieves multiple functions (detecting different aspects of outside information) through a unified structure with intersecting detecting reference axes, reducing overall complexity compared to separate single-function sensor systems.
Solution Approach 2:
The patent implements coordination between the first sensor unit and second sensor unit based on their intersecting detecting reference axes. This feedback mechanism allows the sensors to work together systematically, where the relationship between the intersecting axes provides geometric feedback that simplifies the integration and calibration process, reducing the complexity that would otherwise arise from multiple independent sensors.
3Measurement precision
If sensor units are mounted to improve detection capability, then detection accuracy is improved, but maintenance labor increases
Solution Approach 1:
The patent combines multiple sensor units into a single integrated sensor system with a common mounting structure. This merging approach allows maintenance personnel to service the entire sensor system through a unified access point and mounting interface, significantly reducing maintenance labor compared to servicing multiple separate sensor units that would require individual access and adjustment procedures.
4Measurement precision
If sensor units are made adjustable to improve detection accuracy, then detection reference position flexibility is improved, but ease of operation deteriorates
Solution Approach 1:
The patent employs a switching device that controls the aiming mechanisms based on operational conditions. This feedback system automatically manages the adjustment process, allowing the sensor units to be adjusted when needed (improving detection reference position flexibility) while preventing unnecessary or incorrect adjustments by general users (maintaining ease of operation). The switching device acts as an intelligent gatekeeper that enables professional adjustment while restricting user interference.

AI summary
A first camera unit (111) acquires an image including at least an area ahead of a vehicle based on a first optical axis (X1). A second camera unit (112) acquires an image including at least an area on the left of the vehicle based on a second optical axis (X2). When viewed from an up-down direction of the vehicle, the first optical axis (X1) and the second optical axis (X2) intersect with each other.
