Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional damping devices are used for high energy impacts, then they can provide basic cushioning, but they suffer from structural deformation and breakage under tangential impact forces
Solution Approach 1:
The device divides the impact resistance function into separate components: springs for normal force absorption and reinforcement bars for tangential force resistance. This segmentation allows each component to specialize in handling specific force components, preventing structural failure.
Solution Approach 2:
The device combines different material properties by using elastic springs for energy absorption and rigid reinforcement bars for structural stability. This composite approach creates a system that can withstand both compressive and shear stresses without deformation or breakage.
2Object-affected harmful factors
If damping devices absorb high energy impacts, then they protect structures, but they risk deformation of their own components
Solution Approach 1:
The reinforcement bars are pre-positioned to provide structural support before impact occurs. This preliminary structural preparation prevents deformation during the actual impact event by maintaining geometric stability while the springs absorb energy.
Solution Approach 2:
The device changes the mechanical parameters of the system by introducing elements with different stiffness characteristics. The springs provide compliance for normal forces while the rigid bars maintain dimensional stability, allowing the structure to absorb energy without permanent deformation.
3Reliability
If reinforcement structures are added to prevent deformation, then structural integrity improves, but device complexity increases
Solution Approach 1:
The device merges the cushioning function and structural support function into a single integrated assembly. The springs and reinforcement bars work together as a unified system, eliminating the need for separate cushioning and support structures.
Solution Approach 2:
The combination of springs and reinforcement bars creates a multi-functional component system that simultaneously handles normal impact forces, tangential forces, and structural stability requirements, reducing the need for additional specialized components.
