Solution Overview
Problem
Existing computerized injectors face challenges in accurately identifying and managing medicament cartridges due to limitations in data communication, particularly when cartridges are inserted at varying rotational orientations, which can affect the efficiency and reliability of medicament administration.
Innovation Solution
A computer-controlled injector system equipped with an electromagnetic detector, preferably an annular antenna, that can read and write data to a data tag on the medicament cartridge regardless of its rotational orientation, ensuring consistent communication and optimal data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional electromagnetic detector is used that requires specific rotational orientation, then data communication reliability is improved when properly aligned, but the device becomes difficult to operate when cartridges are inserted at varying orientations
Solution Approach 1:
The electromagnetic detector is configured with an annular (ring-shaped) antenna structure that provides 360-degree rotational symmetry. This curved geometric design allows the detector to maintain consistent electromagnetic coupling with the data tag regardless of the cartridge's rotational orientation, eliminating the need for precise alignment during insertion while ensuring reliable data communication.
2Measurement precision
If the electromagnetic detector is positioned to read data tags at specific orientations, then measurement precision of data tag information is improved, but the device loses adaptability to different cartridge orientations
Solution Approach 1:
The annular electromagnetic detector design provides universal functionality across all rotational orientations. The ring-shaped antenna creates an electromagnetic field that uniformly surrounds the central axis, enabling the detector to accurately read data tags regardless of how the cartridge is rotated during insertion, thus achieving both precision and adaptability simultaneously.
3Adaptability or versatility
If multiple electromagnetic detectors are added to cover all orientations, then coverage of all rotational positions is improved, but device complexity increases
Solution Approach 1:
Instead of using multiple discrete detectors positioned at different angles, the invention employs a single annular electromagnetic detector whose ring geometry inherently provides 360-degree coverage. This curved design consolidates what would otherwise require multiple components into one element, maintaining full orientational coverage while minimizing device complexity.
