Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional rigid bumper assembly is used, then the structural strength is maintained, but the bumper is prone to breaking off when subjected to impact force
Solution Approach 1:
The bumper assembly incorporates pivoting members that allow the buffering assemblies to dynamically adjust their orientation during impact. The buffering assemblies can pivot relative to the bumper and car body, transforming from a rigid static structure to a dynamic system that adapts to impact forces, thereby preventing breakage while maintaining protective function
Solution Approach 2:
The invention changes the physical state and configuration parameters of the bumper assembly by introducing elastic members that can deform and pivoting members that can change orientation. These parameter changes allow the system to absorb impact energy through controlled deformation and angular adjustment rather than rigid resistance, preventing structural failure
2Device complexity
If a single buffering assembly is used, then the structure is simple, but the impact force distribution is insufficient
Solution Approach 1:
The bumper assembly is segmented into multiple independent buffering assemblies (at least two), each capable of independently absorbing and distributing impact forces. This segmentation allows the total impact force to be distributed across multiple elements rather than concentrated on a single structure, improving force distribution while maintaining reasonable structural complexity
Solution Approach 2:
Multiple buffering assemblies are combined with the bumper and pivoting members to create an integrated force distribution system. The merging of multiple buffering elements working together provides superior impact force distribution compared to a single assembly, while the modular design keeps the overall structure manageable
3Ease of manufacture
If fixed-angle buffering assemblies are used, then the manufacturing is easier, but the adaptability to different impact angles is reduced
Solution Approach 1:
The buffering assemblies are designed with pivoting capabilities, transforming from fixed-angle static structures to dynamic elements that can automatically adjust their orientation in response to impact forces from various directions. This dynamic adaptation occurs through the pivoting members that allow angular adjustment during impact events
Solution Approach 2:
The pivoting members enable the buffering assemblies to self-adjust their orientation automatically in response to impact forces without requiring external control or pre-programming for different impact scenarios. The system serves itself by naturally adapting to the direction and magnitude of applied forces through the mechanical pivoting action

AI summary
A bumper assembly for a car includes a bumper and at least two buffering assemblies inclined to each other. Each buffering assembly includes an elastic member, a pivoting member, and a coupling rod. The pivoting member is coupled to a first end portion of the elastic member. The pivoting member is configured to pivot to the car. The coupling rod is coupled to a second end portion of the elastic member. An end portion of the coupling rod away from the elastic member is pivoted to the bumper.
