Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radars are integrated into bumpers to enhance functionality and value, then the bumper's functionality is enhanced, but the radar becomes susceptible to vibrations from unsmooth road conditions, reducing detection precision
Solution Approach 1:
A flexible support structure with U-shaped cantilever beams is introduced as an intermediary between the bumper and the radar. This mediator absorbs vibrations through elastic deformation of the U-shaped beams, isolating the radar from bumper vibrations while maintaining the integrated bumper-radar configuration
Solution Approach 2:
The support structure utilizes elastic deformation of the U-shaped cantilever beams to change the mechanical parameters (vibration amplitude) transmitted to the radar. The flexible support allows controlled deformation to absorb vibration energy, reducing the transmission of vibrational forces to the radar sensor
2Measurement precision
If high-precision radars are placed in stable regions like body frame or grille, then detection precision is maintained, but the arrangement flexibility of the radar is limited
Solution Approach 1:
The flexible support acts as a vibration-isolating intermediary that enables radar placement in bumper regions previously unsuitable for high-precision radars. By decoupling the radar from direct rigid mounting to the bumper, the system achieves both vibration isolation and enhanced arrangement flexibility
Solution Approach 2:
The support structure transitions from a rigid fixed mounting to a dynamic flexible mounting system. The U-shaped cantilever beams provide controlled compliance and vibration absorption, allowing the radar to maintain stability while enabling placement in previously inaccessible bumper locations
3Stability of the object's composition
If rigid support structures are used to stabilize the radar, then vibration resistance is improved, but the ability to absorb vibration deviation is reduced
Solution Approach 1:
The support structure employs flexible U-shaped cantilever beams that can elastically deform to absorb vibrations. This flexible support structure provides vibration isolation while maintaining adequate radar stability, overcoming the limitations of rigid mounting
Solution Approach 2:
The flexible U-shaped support beams provide beforehand cushioning by absorbing vibration energy through elastic deformation before these vibrations can reach and affect the radar. This pre-cushioning mechanism protects the radar from harmful vibrational forces

AI summary
The invention provides a flexible radar support for absorbing vibration deviation, comprising a support base and a support top cover that are engaged with each other in an interlocking manner. A housing space for arranging a radar is formed between the support base and the support top cover. The support base comprises: a centrally arranged base center, and a base edge circumferentially arranged around the base center. The base edge and the base center are connected through four flexible structures that form U-shaped cantilever beams protruding towards the support top cover. With the flexible radar support provided by the invention, thanks to the design of U-shaped flexible structures, even in the situation where an automobile body vibrates at a large amplitude, the flexible radar support can still absorb swaying in the up and down, and left and right directions during the course of driving, thereby reducing the impact of the automobile body's vibrations on the detection precision of a radar.
