Solution Overview
Problem
Existing liquid injection systems face challenges in efficiently and accurately supplying a liquid to multiple vessels simultaneously, requiring precise control over piston movement and varying measuring space dimensions, which is costly and difficult to achieve with traditional designs.
Innovation Solution
A liquid injection apparatus with synchronized pistons and stroke conversion mechanisms allows for simultaneous operation of multiple measuring units with a shared driving mechanism, enabling independent control of piston movement through spring-based connecting mechanisms and direct coupling, accommodating varying measuring space sizes for precise and efficient liquid delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple driving mechanisms are used for each measuring unit, then piston movement control precision is improved, but device complexity and cost increase
Solution Approach 1:
The invention introduces stroke conversion mechanisms that independently adjust the stroke of each piston, segmenting the control function from the driving mechanism. This allows a single driving mechanism to control multiple pistons with different stroke requirements, reducing the number of driving mechanisms while maintaining precise control over each piston's movement.
Solution Approach 2:
The stroke conversion mechanism acts as an intermediary between the driving mechanism and the pistons. It receives the driving motion and converts it into the required stroke for each measuring unit, enabling precise control without requiring separate driving mechanisms for each unit.
2Ease of manufacture
If measuring space dimensions are made uniform, then manufacturing cost is reduced, but precision in accommodating different liquid volumes is worsened
Solution Approach 1:
The invention makes the piston stroke dynamic and adjustable through stroke conversion mechanisms. This allows the system to accommodate different liquid volumes by adjusting the stroke length rather than requiring different measuring space dimensions, thereby maintaining manufacturing simplicity while achieving measurement precision.
Solution Approach 2:
The system changes the stroke parameter of the pistons to adapt to different liquid volume requirements. By adjusting the stroke length through the stroke conversion mechanism, the system can precisely measure and deliver different volumes without changing the physical dimensions of the measuring spaces.
3Ease of operation
If multiple driving mechanisms are used, then operational independence of each measuring unit is improved, but spatial efficiency and cost-effectiveness are worsened
Solution Approach 1:
The stroke conversion mechanism provides a universal solution that enables a single driving mechanism to operate multiple measuring units independently. Each measuring unit can be adjusted to its required stroke through the conversion mechanism, maintaining operational independence while improving spatial efficiency and reducing costs.
4Measurement precision
If high precision measuring spaces are manufactured, then liquid delivery accuracy is improved, but manufacturing cost and difficulty increase
Solution Approach 1:
The invention transitions from static precision (fixed measuring space dimensions) to dynamic precision (adjustable piston stroke). The stroke conversion mechanism allows precise liquid delivery by adjusting the stroke length rather than requiring high-precision manufacturing of the measuring spaces, significantly reducing manufacturing difficulty.
