Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expensive pressure monitoring equipment is used, then pressure control accuracy is improved, but device cost increases
Solution Approach 1:
The pressure relief valve is integrated directly into the handle component, allowing the system to self-monitor and self-regulate pressure without requiring external monitoring equipment. The valve automatically releases pressure when the preselected threshold is reached, making the system self-sufficient for pressure control.
Solution Approach 2:
The pressure relief valve acts as an intermediary mechanism between the inflation source and the medical device, mediating pressure control by automatically releasing excess pressure. This intermediary component eliminates the need for complex external monitoring systems while maintaining accurate pressure control.
2Ease of operation
If external inflation sources are used, then inflation capability is improved, but device complexity increases
Solution Approach 1:
The inflation mechanism is merged with the handle component, creating an integrated self-contained system. The syringe, plunger, and pressure relief valve are all incorporated into the handle assembly, eliminating the need for separate external inflation sources and reducing overall system complexity.
Solution Approach 2:
The handle component serves multiple functions: it houses the inflation mechanism, controls pressure delivery, and incorporates the pressure relief valve. This multi-functional design consolidates what would otherwise require separate external devices, simplifying the overall system while maintaining full inflation capability.
3Reliability
If pressure relief valve is integrated into handle component, then over-pressurization risk is reduced, but manufacturing complexity increases
Solution Approach 1:
The pressure relief valve is designed as a separate, modular component that can be independently manufactured and then integrated into the handle assembly. This segmentation allows for specialized manufacturing of the valve component while keeping the overall manufacturing process manageable through modular assembly.

Data Source
AI summary
A handle component of a medical device is disclosed for delivering a material to an enclosed cavity or space. The handle component includes a self-contained mechanism for holding the material and for providing or releasing the material to the enclosed cavity. The handle component also includes a pressure relief valve in fluid communication with the mechanism and the enclosed cavity. The pressure relief valve is configured to indicate when delivery of the material to the enclosed cavity reaches a preselected or set pressure and to thereby assure precise filling of the enclosed cavity with the material.
