Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If usage data is stored in the pump device itself, then data portability and accessibility are improved, but data management complexity and energy profile correction difficulties increase
Solution Approach 1:
The patent introduces a controller device as an intermediary between the pump device and external systems. The controller receives usage data from the pump's memory device, manages the data, and can correct energy profiles. This intermediary approach maintains data portability while reducing the complexity burden on the pump device itself.
2Ease of operation
If the controller device is reusable and pump devices are disconnected and reconnected, then system flexibility and ease of operation are improved, but data transfer reliability and energy profile accuracy deteriorate
Solution Approach 1:
The patent implements feedback mechanisms where the controller device receives usage data from the pump device after disconnection and reconnection events. The controller can detect discrepancies in energy profiles and initiate correction procedures, ensuring data integrity is maintained despite the flexible connect/disconnect operation cycle.
3Measurement precision
If energy requirement profiles are stored in the pump device memory, then energy management precision is improved, but memory capacity requirements and device complexity increase
Solution Approach 1:
The patent extracts the energy requirement profile data from the pump device memory and stores it in the controller device's memory. This extraction reduces the memory capacity requirements of the disposable pump device while maintaining precise energy management capabilities through the reusable controller that has sufficient storage capacity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enhances user safety and compliance by allowing for retrospective analysis of medicine delivery, automatic correction of energy profiles, and prevention of depleted battery use, while being portable and concealable.
Implementation Method 1
a drive system to dispense medicine from the pump device
Implementation Method 2
The pump device includes a memory device that stores an event log of pump system operations
Implementation Method 3
The controller device receives the energy requirement profile from the memory device and initiates a medicine dispensing operation by supplying a pattern of voltage pulses from the energy storage source to the drive system
Implementation Method 4
The pump device may also include a battery

AI summary
A pump system can include a pump device and a controller device removably attachable to the pump device. The controller device can be reusable, and one or more pump devices can be disconnected and reconnected to the controller device. As such, some pump usage data can be conveniently stored in the pump device itself. In such circumstances, the controller device can receive data related to the pump's history or other usage when the pump device is attached to the controller.
