Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual assembly is used for small radar components, then assembly flexibility is maintained, but assembly efficiency and yield rate are low
Solution Approach 1:
The base and housing are designed with self-positioning features including engaging members, engaging portions, and alignment marks that enable the components to automatically find their correct positions during assembly. This self-service mechanism eliminates the need for complex assembly molds or jigs, allowing automated assembly while maintaining high precision for small radar components.
2Manufacturing precision
If assembly molds are used to ensure precise positioning, then positioning accuracy is improved, but assembly process complexity and labor costs increase
Solution Approach 1:
The engaging members and engaging portions are designed with asymmetric geometries that provide unique orientation and positioning. The alignment marks feature asymmetric patterns that guide correct placement. This asymmetric design ensures precise positioning of the base relative to the housing without requiring complex external molds or fixtures, enabling both high precision and simplified assembly processes.
3Stability of the object's composition
If multiple engagement points are distributed around the circumference, then structural stability is improved, but assembly alignment difficulty increases
Solution Approach 1:
The alignment marks are pre-positioned on the base and housing before assembly begins. These marks provide visual guidance that simplifies the initial alignment process. Once aligned using these preliminary markers, the multiple engaging members and engaging portions distributed around the circumference automatically maintain proper relative positions, ensuring both ease of alignment and structural stability.

AI summary
A vehicle radar includes a housing, a base, and a sensor. The housing defines a circumference, and includes a front portion, a rear portion, and a body. The front portion is formed to have a front opening, the rear portion is formed to have a rear opening, and the front opening is in communication with the rear opening. The body is disposed between the front portion and the rear portion, and includes a plurality of engaging members having different distances from one another on the circumference. The base includes a plurality of engaging portions aligned with the engaging members. The sensor is disposed on the base.
