Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a microprocessor and memory are integrated into the implantable medical device, then the device can store and execute complex control algorithms for pacing therapy, but the device size and power consumption increase
Solution Approach 1:
The patent extracts the microprocessor and memory from the implantable medical device and places them in an external programmer. This allows the IMD to maintain a simple, small form factor while still accessing complex control algorithms through the external device that communicates with the IMD via telemetry.
Solution Approach 2:
The external programmer acts as an intermediary between the user and the IMD. It contains the microprocessor and memory needed for complex computations, while communicating with the simpler IMD through a telemetry interface, thus providing advanced functionality without increasing IMD complexity.
2Adaptability or versatility
If a microprocessor and memory are integrated into the implantable medical device, then the device can store and execute complex control algorithms for pacing therapy, but the power consumption increases
Solution Approach 1:
The power-intensive microprocessor and memory are extracted from the battery-powered IMD and placed in the externally-powered programmer. This allows complex computations to be performed outside the body where power is readily available, preserving the IMD's long battery life.
Solution Approach 2:
The external programmer serves as a power-providing intermediary that performs computationally intensive tasks. The IMD only needs to execute simpler instructions and communicate data, dramatically reducing its power consumption and extending battery operation.
3Productivity
If a leadless ventricular pacing therapy is implemented, then the atrial kick is preserved for efficient ventricular filling, but the ventricle cannot be sensed or paced
Solution Approach 1:
The patent segments the pacing functionality into two separate devices: a leadless ventricular pacemaker that provides pacing only, and a separate atrial pacemaker that provides both pacing and sensing. This allows each device to be optimized for its specific function while together they provide complete AV sequential pacing capability.
4Adaptability or versatility
If a traditional biventricular pacing system with leads is used, then both ventricles can be paced and sensed, but the device complexity and surgical invasiveness increase
Solution Approach 1:
The patent extracts the leads and lead-related complexity from the system by using leadless pacemakers. The pacing leads are replaced by leadless devices that are implanted directly in the cardiac chambers, eliminating the need for venous access, lead threading, and connector assembly while maintaining biventricular pacing capability.
5Adaptability or versatility
If a traditional biventricular pacing system with leads is used, then both ventricles can be paced and sensed, but the surgical invasiveness increases
Solution Approach 1:
The patent removes the invasive leads from the system architecture. Leadless pacemakers are implanted percutaneously through the femoral vein and deployed directly into the cardiac chambers using delivery catheters, eliminating the need for surgical sternotomy, muscle cutting, and lead insertion through venous puncture and manipulation.
Solution Approach 2:
The patent replaces the mechanical lead system with a fully implantable electronic system. The leadless pacemakers communicate with the external programmer and each other through electromagnetic fields via telemetry, eliminating the need for physical electrical connections through leads and connectors.

AI summary
A reset device for resetting a controller of a motor is provided. The device comprises a first delay circuit configured to discharge a first voltage and a second delay circuit configured to discharge a second voltage. A reset circuit is configured to provide a reset signal to the controller. The first delay circuit and second delay circuit are arranged to be charged from a physical connector, and to discharge upon removal of the physical connector. The first delay circuit triggers the reset circuit to provide the reset signal when the first voltage meets a first threshold condition relative to the second voltage.
