Micro-Injection Flow Channel Assembly With Adjustable Impact Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid micro-injection devices face issues with frequent wear and maintenance due to non-adjustable impact force, low precision in fluid ejection, and cumbersome installation and disassembly processes, leading to inefficient fluid ejection and high maintenance costs.
Innovation Solution
An execution system for fluid micro-injection devices featuring a base body with a movable executor, an adjusting member, and clearance sheets to adjust the pre-tightening force, allowing for precise control of fluid ejection by varying the number or thickness of clearance sheets between the executor and the base body's inner wall, thereby enhancing the fluid ejection effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a flexible hinge mechanism or operating element is used to perform secondary movement of closing element, then fluid micro-injection can be achieved, but both ends of the closing element wear out quickly requiring frequent replacement and maintenance
Solution Approach 1:
The patent implements an adjustable executor mechanism where the closing element's position and pre-tightening force can be dynamically adjusted through clearance sheets and positioning holes. This dynamic adjustment capability allows optimization of contact forces and movement characteristics, reducing wear on the closing element ends while maintaining fluid ejection functionality.
2Adaptability or versatility
If the closing element lifting height is not adjustable or adjustment precision is low, then the structure is simple, but the impact force for fluid ejection cannot be accurately adjusted
Solution Approach 1:
The patent employs clearance sheets with different thicknesses and positioning holes at various positions to change the geometric parameters of the executor system. By selecting different clearance sheet thicknesses and positioning hole locations, the closing element lifting height and pre-tightening force can be precisely adjusted, enabling accurate control of impact force for fluid ejection.
3Productivity
If the executor structure is fixed with non-adjustable pre-tightening force, then the structure is simple, but fluid ejection effect cannot be optimized
Solution Approach 1:
The patent segments the executor structure into modular components including the closing element, executor body, clearance sheets, and positioning mechanism. This segmentation allows independent adjustment of pre-tightening force and positioning through interchangeable clearance sheets and positioning holes, optimizing fluid ejection effect without creating excessive overall structural complexity.
4Productivity
If traditional mounting structures are used for the executor, then installation is straightforward, but installation and disassembly are cumbersome resulting in low installation efficiency
Solution Approach 1:
The patent implements a dynamic mounting system where the executor can be quickly installed and removed from the base body through the positioning hole and clearance sheet mechanism. This dynamic mounting approach allows rapid assembly and disassembly operations, significantly improving installation efficiency compared to traditional fixed mounting structures.
