Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input of functional instructions on a remote device is used, then the infusion system can be controlled, but the operation process becomes cumbersome and user experience deteriorates
Solution Approach 1:
The patent replaces the mechanical manual input system (buttons, switches on remote device) with a sensing system that detects body movements. The control unit interprets these movements as functional instructions, eliminating the need for manual button pressing and significantly simplifying the operation process while reducing the time required to input commands.
Solution Approach 2:
The infusion system performs self-service by automatically detecting the user's intended commands through body movement sensing. The system interprets movements such as arm raising, leg lifting, or body tilting as specific functional instructions, allowing the user to control the infusion pump through natural gestures without needing to manually operate the remote device.
2Ease of operation
If body movement sensing is implemented, then the input process is simplified and user experience is enhanced, but the device complexity increases
Solution Approach 1:
The sensing unit is designed with multi-functionality, serving both as a motion detector and as a control interface interpreter. The same sensing unit that detects body movements also works in conjunction with the control unit to recognize and execute functional instructions, eliminating the need for separate control mechanisms and reducing overall system complexity despite the added sensing capability.
Solution Approach 2:
The patent merges the sensing unit with the control unit into an integrated system. The sensing unit detects body movements and the control unit processes these signals to generate functional instructions, combining what could have been separate modules into a unified control architecture that minimizes complexity while achieving the desired functionality.
3Adaptability or versatility
If multiple infusion modes and rates are enabled, then the system flexibility is improved, but the control system complexity increases
Solution Approach 1:
The patent implements dynamic control of infusion parameters by allowing the system to switch between multiple infusion modes (continuous, intermittent, bolus) and rates based on real-time sensing data and pre-programmed protocols. The control unit dynamically adjusts infusion parameters without requiring complex manual configuration, as the body movement sensing provides natural input for mode selection and parameter adjustment.
