Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional needle-free injection systems are complex, costly, and suffer from poor production quality, leading to reduced gene transfer efficiency and increased discomfort due to loose connections and cumbersome operation.
Innovation Solution
A needle-free injection system with an adapter tube for easy connection and disassembly of the output pipe and pressure accumulator, a touch control panel for real-time delivery adjustments, and a design that reduces turbulence and space requirements, using a pressure accumulator with a solenoid valve and a venturi or jet engine type output pipe for efficient delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the output pipe is directly connected to the pressure accumulator without an adapter tube, then the structure is simpler, but the connection becomes loose during use reducing reliability
Solution Approach 1:
An adapter tube is introduced as an intermediary component between the pressure accumulator and the output pipe. The adapter tube includes a first connecting end that couples to the pressure accumulator and a second connecting end that couples to the output pipe, providing a stable intermediate connection that prevents loosening while maintaining overall system simplicity
2Adaptability or versatility
If the control panel is connected via external wires, then the control function is complete, but the usage space and placement space increase
Solution Approach 1:
The control panel is merged with the pressure accumulator by fixing it directly on the outer surface of the pressure accumulator. This integration eliminates the need for external wire connections and external controller placement, reducing both usage space and placement space while maintaining full control functionality
3Reliability
If the adapter tube connects both ends to the pressure accumulator and output pipe respectively, then the connection stability improves, but the manufacturing complexity increases
Solution Approach 1:
The adapter tube is designed as a segmented component with distinct functional zones: a first connecting end for the pressure accumulator and a second connecting end for the output pipe. This segmentation allows each end to be optimized for its specific connection type while maintaining overall manufacturing simplicity through modular design

AI summary
The invention provides a needle-free injection system, which mainly includes a pressure accumulator, an output pipe, a delivery device and a fluid supply device. The front end of the pressure accumulator is connected to the output pipe, and the bottom end of the pressure accumulator can be connected to the fluid supply device and/or a hand-holding device. A control panel and a shooting button are fixed on the outer surface of the pressure accumulator. The control panel is electrically connected to the delivery device, and can store a delivery program to control the delivery steps of a delivery material stored in the delivery device, such as the delivery time, delivery quantity or delivery times of the delivery material into the output pipe. In this way, not only the convenience of use can be improved, but also the use space of the needle-free injection system can be reduced.
