Solution Overview
Problem
The existing injector for automatically mixing powder for injection has a complex manufacturing process and structure, making it costly and difficult to assemble due to the need for precise spiral or arc slots and multiple sleeves.
Innovation Solution
A simplified device with a solvent bottle, needle, and impelling units where the solvent bottle drives the solvent slide along the solute bottle, using elastic force to facilitate mixing without the need for complex slots or multiple sleeves, allowing the needle to penetrate both bottles for efficient mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spiral shape or arc with certain angle are made in the inner wall of turntable sleeve, then the mixing function can be achieved, but the manufacturing process becomes complex and costs a lot
Solution Approach 1:
The patent removes the complex spiral or arc slots from the turntable sleeve structure. Instead, it uses a simple linear restrict slot that guides the impelling sleeve in a straight path, extracting the complexity from the design while maintaining the mixing function through a different mechanism
Solution Approach 2:
Instead of creating complex curved paths in the turntable sleeve, the patent inverts the approach by using a simple linear restrict slot combined with a turntable mechanism that rotates the entire assembly, achieving the mixing effect through rotational movement rather than curved guiding slots
2Reliability
If multiple sleeves including solute bottle, solvent bottle and turntable bottle are used, then the mixing function can be achieved, but the structure becomes complex and difficult to assemble
Solution Approach 1:
The patent merges the functions of multiple separate sleeves into a single integrated turntable sleeve structure. The turntable sleeve combines the guidance function, the rotational mechanism, and the restrict slot functionality in one component, reducing the number of separate parts and simplifying assembly
Solution Approach 2:
The turntable sleeve serves multiple functions simultaneously: it guides the impelling sleeve through the linear restrict slot, provides rotational movement for mixing, and acts as the structural framework for the entire mixing mechanism, eliminating the need for separate dedicated components for each function

AI summary
A device for automatically mixing powder for injection, includes an injector body, a solvent bottle, a needle, a first impelling unit and a second impelling unit. The injector body has a solute bottle and its mouth is opposite the mouth of the solvent bottle. The first impelling unit is disposed upon the solvent bottle. The second impelling unit is sleeved with a needle and located between the mouth of solute bottle and mouth of solvent bottle. A first and a second impelling sleeve-are driven by the solvent bottle to slide along the solute bottle, so the first end of the needle is fixed and extend through the solute bottle. The solvent bottle drives the first impelling sleeve and second impelling sleeve to turn with each other. The second impelling sleeve slides opposite the first impelling sleeve to make the second end of the needle extend through the solvent bottle.
