Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wound packing with gauze is used, then bleeding can be controlled, but the procedure requires advanced first aid knowledge and immediate application to prevent clot dislodgment
Solution Approach 1:
The device allows the wound to essentially treat itself by injecting clotting factors and forming a seal automatically. The system self-regulates the injection process and maintains pressure without requiring continuous manual intervention or specialized knowledge of first aid procedures.
Solution Approach 2:
The biocompatible sealant material acts as an intermediary substance that facilitates clot formation and seals the wound. This intermediary material bridges the gap between the injected clotting factors and the wound tissue, enabling effective sealing without requiring the user to have expertise in the complex physiological processes involved.
2Ease of operation
If pressure is reduced on a packed wound, then comfort is improved, but any clots that have formed may become ruptured and dislodged, causing bleeding to resume
Solution Approach 1:
The device maintains continuous pressure through the inflatable balloon mechanism, ensuring that the sealing force is constantly applied to the wound. This continuous action prevents clot dislodgment while allowing for controlled pressure adjustment to balance comfort and effectiveness.
Solution Approach 2:
The system allows dynamic adjustment of pressure levels. The balloon can be inflated to different pressures based on wound severity, and pressure can be monitored and adjusted over time. This dynamic capability enables the system to adapt to changing wound conditions and patient comfort needs.
3Productivity
If typical wound packing is done at a given density immediately following injury, then bleeding flow is slowed, but the procedure requires first aid training and must be done within a very short duration
Solution Approach 1:
The device replaces the manual mechanical process of wound packing with an automated injection and inflation system. The pump mechanism automatically delivers the sealant material at the correct rate and pressure, eliminating the need for users to manually pack wounds with gauze and apply pressure.
Solution Approach 2:
The system uses pneumatic principles through the inflatable balloon and hydraulic principles through the fluid injection mechanism. These engineered systems provide controlled delivery of sealing materials and consistent pressure application, replacing the need for trained first aid techniques.
