Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional needle-free injection device is operated in handheld manner, then the device can be used for drug injection, but the nozzle may deviate from the injection position due to operator fatigue or patient movement
Solution Approach 1:
The injection device is mounted on the operator's head, allowing the operator to perform the injection procedure independently without requiring another person to hold or stabilize the device. The head-mounted structure enables the operator to use their own head movements to position and stabilize the nozzle at the injection site throughout the prolonged procedure
Solution Approach 2:
The device incorporates a pivoting assembly with multiple degrees of freedom that allows dynamic adjustment of the nozzle position and angle. The pivot joints enable the nozzle to be positioned at various angles relative to the headband, and the detachable injection device can be repositioned as needed during the injection process
2Duration of action of moving object
If the injection procedure lasts for 10 to 12 minutes, then complete drug administration can be achieved, but operator fatigue and head shaking cause nozzle deviation
Solution Approach 1:
The nozzle position is pre-adjusted and fixed to the headband using the pivoting assembly before the injection procedure begins. This preliminary positioning ensures that the nozzle is correctly aligned with the injection site at the start of the prolonged 10-12 minute procedure, preventing deviation due to fatigue or movement
Solution Approach 2:
The head-mounted structure uses the operator's head as a stable support platform, counteracting the effects of arm fatigue that would occur with handheld operation. The headband distributes the device weight around the head, providing a stable base that resists shaking and maintains nozzle position throughout the extended injection duration
3Productivity
If the nozzle deviates from the injection position, then the injection procedure can continue, but drug waste and poor therapeutic effect occur
Solution Approach 1:
The pivoting assembly provides visual and tactile feedback to the operator about nozzle position relative to the injection site. The adjustable pivot joints allow the operator to sense and correct any positioning deviations, ensuring the nozzle remains aligned with the target area throughout the injection process to prevent drug waste

Function Achieved in This Case
Enables long-time, stable drug administration to the scalp by overcoming manual operation challenges, ensuring precise and consistent injection without nozzle deviation.
Implementation Method 1
the injection device is configured to spray a drug toward the user's head by atomizing penetration
Implementation Method 2
use the high pressure generated by power to make the drug in the syringe penetrate (water column penetration or atomizing penetration) the skin through the nozzle with a jet stream at a high speed of more than 100 meters per second
