Solution Overview
Problem
Existing injection devices for medicament delivery lack a compact and cost-effective solution for precise monitoring and control of user operations, particularly in detecting manual dose settings and dispensing, and require additional sensors for accurate dose measurement.
Innovation Solution
An injection device with an auxiliary electronic device that controls an electric propulsion mechanism, eliminating the need for onboard sensors and electronic control circuits by using a separate auxiliary device for monitoring and controlling the injection process, including dose tracking and power supply, through interconnected interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional sensors and electronic control circuits are added to the injection device for precise monitoring and control, then measurement precision and reliability improve, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent extracts the electronic control circuit and sensor from the injection device itself, placing them in a separate auxiliary electronic device. The injection device retains only the basic mechanical injection function with an electric propulsion mechanism, while the auxiliary device handles all monitoring, control, and data processing functions. This separation reduces the complexity of the injection device while maintaining precise measurement capabilities through the auxiliary device's processor that tracks dose settings and dispensing actions.
2Reliability
If additional sensors and electronic components are integrated into the injection device, then monitoring reliability improves, but manufacturing costs increase
Solution Approach 1:
The patent extracts the expensive electronic monitoring and control components from the injection device and places them in a separate auxiliary electronic device. This allows the injection device to be manufactured using simpler, more cost-effective processes while the auxiliary device, which contains the sensors and processing electronics, can be produced separately and attached to the injection device. The auxiliary device's processor reliably monitors and records all injection operations including dose setting and dispensing.
3Device complexity
If a separate auxiliary electronic device is used for controlling the injection device, then device complexity and manufacturing costs decrease, but the need for additional external components increases
Solution Approach 1:
The auxiliary electronic device is designed as a universal multi-functional unit that can be attached to different injection devices. It provides power supply through the electric power connector, monitors injection operations via the data connector, controls the electric propulsion mechanism, and stores injection data in its memory. This universal design allows the same auxiliary device to work with multiple injection device models, reducing the need for device-specific electronic components while maintaining full monitoring and control capabilities.
