Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If welding is used to assemble the ballistic wall and target system, then the structure is strong and stable, but the system becomes difficult to disassemble, transport, and modify
Solution Approach 1:
The ballistic wall and target system are divided into separate modular components that can be independently assembled and disassembled. The wall panels, target mounts, and support structures are distinct pieces connected through mechanical interfaces rather than permanent welding, enabling easy reconfiguration while maintaining structural integrity during use.
Solution Approach 2:
The system transitions from a static welded structure to a dynamic modular assembly that can be easily reconfigured. Mechanical fasteners and connection mechanisms allow the structure to be assembled, disassembled, and reconfigured multiple times while maintaining strength during each operational state.
2Stability of the object's composition
If welding is used to assemble the ballistic wall, then the structure is permanent and stable, but the steel is weakened and more susceptible to damage from bullet impacts
Solution Approach 1:
The welding process is completely removed from the assembly system. Instead of joining metal through fusion that creates vulnerable zones, mechanical fasteners and connection mechanisms are used that do not compromise the steel's inherent strength and impact resistance properties.
Solution Approach 2:
Mechanical fasteners and connection elements serve as intermediaries between structural components. These mediators transmit loads without requiring direct metal-to-metal fusion, preserving the full strength of the steel components while achieving stable structural assembly.
3Stability of the object's composition
If the target system is assembled as a large welded structure, then it is stable, but it is difficult to ship and requires welding on site
Solution Approach 1:
The complete target system is segmented into transportable modular units that can be shipped separately and assembled at the destination using simple mechanical connections. This eliminates the need for on-site welding while maintaining structural stability through proper mechanical fastening of the modular components.
Solution Approach 2:
The modular components are designed with universal connection interfaces that work across different assembly configurations. The same mechanical fasteners and connection mechanisms serve multiple functions during shipping, storage, and final assembly, simplifying the entire process from manufacture to deployment.
4Stability of the object's composition
If the target system is made as a permanent welded structure, then it is stable, but it cannot be modified without cutting or welding
Solution Approach 1:
The system is divided into independent modular components with standardized connection interfaces. This segmentation enables easy modification by adding, removing, or repositioning individual modules without affecting the stability of the overall structure, as each module can be independently adjusted through mechanical connections.
Solution Approach 2:
The system transitions from a static permanent structure to a dynamic modular configuration that can be easily adapted. Mechanical connections allow for flexible reconfiguration while maintaining structural stability, enabling the system to evolve and be customized for different applications without cutting or welding.
