Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional acupuncture devices face challenges with high operational difficulty, low penetration efficiency, and inconsistent treatment outcomes due to manual needle insertion and separate firing and reset mechanisms, which hinder continuous firing and reduce acupuncture efficiency.
Innovation Solution
An acupuncture device with an integrated needle gun and storage portion, featuring an energy storage mechanism, trigger mechanism, and energy-increasing mechanism within the gun shell, allowing for continuous firing and efficient needle insertion without manual twisting, facilitated by a spring or elastic member and mechanical/electric impact source mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual twisting operation is used for needle insertion, then operational flexibility is maintained, but operational difficulty increases and penetration efficiency decreases
Solution Approach 1:
The patent replaces the manual twisting operation with an automatic firing mechanism that uses a spring-loaded impact system to propel needles through the skin. The trigger mechanism activates a stored energy spring that rapidly drives the needle forward, eliminating the need for manual twisting and significantly reducing operational difficulty while increasing penetration efficiency.
Solution Approach 2:
The patent employs a pre-loaded spring mechanism that stores energy before needle insertion. The spring is compressed in advance and held in place by a trigger mechanism, allowing for rapid needle deployment when activated. This preliminary energy storage enables quick, efficient needle penetration without requiring manual twisting during the actual insertion process.
2Productivity
If separate firing and reset mechanisms are provided, then firing function is achieved, but device complexity increases and continuous firing capability is reduced
Solution Approach 1:
The patent combines the firing and reset functions into a single integrated mechanism. The trigger mechanism serves dual purposes: when activated, it releases the stored spring energy to fire the needle, and when released, it automatically allows the spring to reset to its loaded position. This merging of functions eliminates the need for separate firing and reset mechanisms, enabling continuous firing while reducing overall device complexity.
Solution Approach 2:
The patent designs the mechanism so that the reset action occurs automatically and continuously as part of the trigger's natural movement cycle. As the trigger is released after firing, the spring automatically returns to its compressed state, preparing for the next needle insertion without requiring separate reset operations. This continuous cycle of firing and automatic resetting maintains high productivity.
3Productivity
If rapid needle insertion is implemented, then acupuncture efficiency increases, but pain for patient may increase
Solution Approach 1:
The patent uses a controlled impact mechanism where the spring stores energy and releases it in a precise, localized manner. Rather than applying continuous force, the mechanism delivers a single, rapid impulse that is sufficient for needle penetration. The energy delivery is calibrated to be just enough to penetrate the skin quickly, minimizing the duration of any discomfort while maintaining high acupuncture efficiency.
