Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate parts are joined together to reduce assembly difficulty, then ease of assembly is improved, but strength at joints deteriorates
Solution Approach 1:
The barrier system is divided into modular components (posts, transverse barrier elements, attachment elements) that can be easily assembled and disassembled. The segmentation allows for simple assembly operations while maintaining joint strength through the elastic deformation mechanism.
Solution Approach 2:
The material properties of the posts are designed to change under impact conditions. The posts exhibit elastic deformation that increases friction and mechanical interlocking at the joints during impact, thereby strengthening the connections dynamically while maintaining ease of assembly under normal conditions.
2Strength
If a permanent structure is used to ensure strength, then strength is improved, but adaptability to various geometries deteriorates
Solution Approach 1:
The barrier system transitions from a static permanent structure to a dynamic modular system. The posts can deform elastically under impact to provide strength, while the modular components can be reconfigured to adapt to different geometries and protection requirements.
Solution Approach 2:
The standardized posts and attachment grooves serve multiple functions: they provide structural support, enable easy assembly/disassembly, and allow adaptation to various geometries through different configurations of transverse barrier elements. The universal design maintains strength while providing versatility.
3Strength
If rigid barrier elements are used to provide protection, then protection capability is improved, but ability to absorb repeated impacts deteriorates
Solution Approach 1:
The posts are designed with specific material properties that allow elastic deformation under impact loads. This parameter change enables the posts to absorb impact energy through reversible deformation, maintaining protection capability while reliably withstanding repeated impacts without permanent damage.
Solution Approach 2:
The elastic posts provide inherent cushioning capability before impacts occur. The material properties are selected to allow controlled deformation that absorbs impact energy, protecting the barrier system from damage during repeated impacts while maintaining structural integrity.
