Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user interface with haptic feedback is implemented, then user control and privacy are enhanced, but device complexity increases
Solution Approach 1:
The patent implements haptic feedback mechanisms that provide tactile responses to user inputs, enabling users to feel resistance or confirmation when adjusting parameters. This feedback loop enhances user control by allowing intuitive interaction without visual confirmation, while the feedback is generated through existing motor drivers and control circuits already present in the infusion device, thereby limiting the increase in overall device complexity.
Solution Approach 2:
The haptic feedback system enables the device to communicate its state and respond to user inputs autonomously through tactile sensations. The system self-regulates by providing natural resistance when approaching parameter limits or preferred values, eliminating the need for additional complex interfaces or communication channels while enhancing ease of operation.
2Measurement precision
If haptic feedback is provided as user approaches predefined limits, then dosing accuracy is improved, but device complexity increases
Solution Approach 1:
The system incorporates haptic feedback that activates when user-adjusted parameters approach predefined limits or preferred values. This feedback mechanism uses the existing motor driver circuits to generate tactile resistance or pulses, providing dosing accuracy enhancement without requiring separate dedicated hardware for limit detection and feedback generation, thus minimizing the increase in device complexity.
Solution Approach 2:
The patent utilizes changes in motor driver parameters (such as pulse width modulation duty cycle or frequency) to generate haptic feedback sensations. By dynamically adjusting these electrical parameters, the system creates tactile responses that indicate proximity to dosing limits, achieving improved dosing accuracy through software-controlled parameter modulation rather than additional hardware complexity.
3Device complexity
If discrete button inputs are used, then device complexity is reduced, but ease of operation and privacy are compromised
Solution Approach 1:
The patent enhances simple button inputs by incorporating haptic feedback mechanisms that provide tactile confirmation of button presses and parameter adjustments. This allows users to operate the device privately without visual confirmation, as the haptic responses provide intuitive feedback through touch alone. The feedback is generated using existing motor driver circuits, maintaining low device complexity while significantly improving ease of operation and user privacy.
