Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a manual pump is used for inflation, then the device can be simpler, but the ease of operation deteriorates as it is difficult for patients to implement effectively
Solution Approach 1:
The patent replaces the manual mechanical pump system with an automated motor-driven pump system. The motor is controlled by a microprocessor that responds to patient input (such as button presses or sensor detection), automatically activating the pump to inflate the implant. This substitution eliminates the need for the patient to manually operate a complex pump mechanism, thereby improving ease of operation while maintaining device functionality.
Solution Approach 2:
The system incorporates self-service capabilities through automated control mechanisms. The microprocessor monitors patient needs and automatically activates the pump without requiring manual intervention for each inflation cycle. The system can detect when inflation is needed and execute the inflation process autonomously, reducing the operational burden on the patient while maintaining simplicity in the overall system design.
2Adaptability or versatility
If multiple functions are integrated in the implanted device, then the functionality improves, but the device complexity increases and requires more space
Solution Approach 1:
The patent implements a multi-functional integrated device where a single implanted unit performs multiple functions: it houses the pump mechanism, contains the fluid reservoir, incorporates sensors for detecting inflation needs, includes a wireless communication module for receiving control signals, and integrates the motor assembly. This universal design consolidates what would traditionally require separate components into one compact implantable device, improving versatility while managing complexity through integrated architecture.
Solution Approach 2:
The patent merges previously separate components (pump, reservoir, motor, control electronics, and sensors) into a single integrated implanted device. The motor is positioned to directly drive the pump mechanism, which draws fluid from the integrated reservoir and delivers it to the inflatable element. This merging of functions into one device reduces the number of separate surgical implantation procedures and simplifies the overall system architecture.
3Ease of operation
If a motor-driven pump is used, then the ease of operation improves, but the device complexity and space requirements worsen
Solution Approach 1:
The patent utilizes hydraulic principles by employing a fluid reservoir and pump system where hydraulic fluid is transferred from the reservoir through the pump to the inflatable element. This hydraulic mechanism allows for efficient force multiplication and compact actuation, enabling the motor-driven pump to achieve the necessary inflation pressure and volume with a smaller, more compact design compared to purely mechanical alternatives.
Solution Approach 2:
The system employs parameter changes in the form of wireless energy transfer to power the motor. By using inductive coupling or electromagnetic resonance between an external charging device and an internal receiving coil, the motor receives power wirelessly, eliminating the need for large battery assemblies or complex wired power delivery systems. This parameter change in the power delivery method significantly reduces the volume of the implanted device while maintaining ease of operation.
