Innovation Solution
An electronic circuit integrated into drug delivery devices that uses wireless communication with mobile devices to determine distance and relative position, enabling or disabling functions based on proximity, thereby providing secure access and aiding in device location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication and position determination are added to the electronic circuit, then user authentication security and device location capability are improved, but device complexity increases
Solution Approach 1:
The communication interface is designed to perform multiple functions: wireless communication with mobile devices, determination of distance and relative position, and authentication of users. By making the communication interface multi-functional, the patent avoids adding separate dedicated components for each function, thereby improving security capabilities while minimizing the increase in device complexity.
2Reliability
If proximity-based function control is implemented, then unauthorized use prevention is improved, but ease of operation may be reduced for users with impaired dexterity
Solution Approach 1:
The system automatically determines the position of the mobile device relative to the electronic circuit and autonomously decides whether to enable or disable functions based on proximity. This self-service mechanism eliminates the need for manual authentication steps, making the device easier to operate for users with impaired dexterity while still preventing unauthorized use through automatic position-based control.
3Measurement precision
If data acquisition and logging functions are added, then measurement precision of dispensing data is improved, but device complexity increases
Solution Approach 1:
The electronic circuit's communication interface is designed to handle multiple tasks including wireless communication, position determination, authentication, and data acquisition/logging. By consolidating these functions into a single multi-functional interface rather than adding separate dedicated components, the patent achieves precise measurement and logging capabilities while minimizing the increase in overall device complexity.
