Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flange or screw-in fastening is used to attach radar sensor to container, then secure attachment is achieved, but device complexity and installation time increase
Solution Approach 1:
The radar sensor housing is designed with a spherical segment outer contour that fits into a corresponding hollow spherical segment in the mounting device, creating a curved geometric interface. This spherical geometry provides inherent mechanical stability and secure attachment while simplifying the overall fastening structure, eliminating the need for complex flange or screw-in mechanisms.
2Reliability
If traditional mounting methods are used, then sensor attachment is achieved, but installation time and user intervention requirements increase
Solution Approach 1:
The mounting device incorporates a hollow spherical segment that passively receives and secures the spherical segment housing of the radar sensor through simple insertion. The spherical geometry provides self-alignment and automatic mechanical engagement, eliminating the need for complex assembly steps, tools, or extensive user intervention, thereby dramatically reducing installation time while maintaining mounting stability.
3Measurement precision
If sensor housing is made of plastic for signal radiation, then measurement signal transmission is improved, but mechanical strength decreases
Solution Approach 1:
The sensor housing is made of plastic material specifically in the area of the antenna unit where measurement signal radiation is required, as plastic allows effective transmission of the measurement signal. Other areas of the housing may be made of different materials with different properties, optimizing both signal transmission and mechanical strength in different regions of the housing structure.
