Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If current intelligent management systems are used, then the system structure is simple, but the measurement precision of injection dose is insufficient
Solution Approach 1:
The patent combines multiple sensing functions (rotation detection, acceleration sensing, movement tracking) into an integrated information collection device that attaches to the injection pen. This merging of multiple measurement capabilities into a single unified system enables precise injection dose reading while avoiding the complexity of multiple separate devices.
Solution Approach 2:
The information collection device serves multiple functions: detecting pressing knob rotation, sensing injection pen movement, validating injection actions, and calculating injection doses. This multi-functionality allows the system to achieve comprehensive measurement precision without requiring separate specialized devices for each function.
2Reliability
If the system records all rotation data, then the quantity of recorded information increases, but the reliability of injection confirmation decreases
Solution Approach 1:
The system uses feedback from multiple sensors to validate injection actions. The gyroscope detects rotation, the accelerometer detects movement, and the processing unit cross-validates these signals to confirm whether an intended injection action occurred. This feedback mechanism ensures reliable injection confirmation while maintaining complete information recording.
Solution Approach 2:
The system performs preliminary validation of injection actions by analyzing sensor data before recording the injection dose. The processing unit determines whether the detected movement and rotation correspond to a valid injection action, preventing false recordings while ensuring complete and accurate information is captured for confirmed injections.
3Ease of operation
If the pressing knob is designed for easy rotation, then the ease of operation improves, but the measurement precision of rotation information may be affected
Solution Approach 1:
The patent replaces mechanical measurement mechanisms with electronic sensing (gyroscope for rotation detection). This substitution allows the pressing knob to be designed for ease of operation with smooth rotation, while the gyroscope accurately captures rotation information electronically, eliminating the trade-off between operational ease and measurement precision.

AI summary
An information collection method for an injection pen includes several steps as follows. The action of the pressing knob is sensed to determine whether the rotation information of the pressing knob is obtained. The traveling movement of the injection pen is sensed to determine whether the movement information of the injection pen is obtained. A determination is made that the traveling movement of the injection pen is conformed as an intending injection action according to the rotation information of the pressing knob and the movement information of the injection pen. When the traveling movement of the injection pen is conformed as the intending injection action, an actual injection dose that the injection content is pushed outwards from the injection pen is calculated according to the rotation information of the pressing knob. The actual injection dose is recorded.
