Solution Overview
Problem
Conventional fluid delivery devices for diabetes treatment are cumbersome, costly, and complex, with tubeless systems experiencing radio interference and inconvenient wearing due to separate components and large size.
Innovation Solution
A disposable tubeless fluid delivery system integrating a pump base, wireless control device, and glucose monitoring capabilities within a single, user-friendly device, featuring a button unit, key unit, fluid reservoir, indwelling cannula, and control unit for seamless fluid delivery and glucose monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fluid delivery device with pump base and separate wireless control device is used, then fluid delivery function is achieved, but device complexity and size increase
Solution Approach 1:
The patent integrates the pump base and wireless control device into a single integrated device. The control unit includes both pump control functionality and wireless communication capabilities, eliminating the need for separate components. This merging reduces the number of parts the patient must wear and carry, directly resolving the contradiction between operational convenience and device complexity.
2Ease of operation
If tubeless fluid delivery device with separate pump base and control module is used, then fluid delivery is achieved, but size and mass increase making it inconvenient to wear
Solution Approach 1:
The patent combines the pump base and control module into a single integrated unit with unified housing. The control unit incorporates both the pump mechanism and wireless control capabilities in one compact structure, reducing the overall mass and volume that the patient must carry, thereby improving wearing convenience.
3Device complexity
If integrated pump base and control module is used, then device size is reduced, but radio interference occurs
Solution Approach 1:
The patent extracts the wireless communication antenna and its control circuitry into a separate wireless communication unit that can be positioned away from the pump mechanism. This spatial separation allows the integrated device to maintain compact size while minimizing radio frequency interference with the pump's mechanical and electrical components.
4Ease of manufacture
If disposable tubeless system is used, then cost is reduced and convenience is improved, but integration of multiple functions in single device increases manufacturing complexity
Solution Approach 1:
The patent designs the integrated device with multi-functional capabilities where a single control unit performs both pump control and wireless communication functions. The unified housing and integrated circuitry allow the device to deliver fluid, monitor glucose, and communicate wirelessly without requiring separate dedicated components for each function, simplifying the manufacturing of the disposable unit while maintaining comprehensive functionality.
