Actuator Bypass Pathway Flow Rate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing actuators in resource recovery and fluid sequestration industries lack precise control over their behavior, leading to inefficiencies in fluid flow and movement of dynamic components relative to static components.
Innovation Solution
The actuator design incorporates a dynamic component, a static component, a seal, and a bypass pathway within the static component. The bypass pathway opens or closes based on the dynamic component's position, adjusting the required flow rate to maintain movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a bypass pathway is added to the actuator, then control precision is improved, but device complexity increases
Solution Approach 1:
The bypass pathway acts as an intermediary element that mediates between the fluid flow and the dynamic component. It provides a controlled leakage path that interacts with the seal to regulate flow rates and control component movement, thereby improving control precision without requiring complex external control systems.
Solution Approach 2:
The actuator utilizes hydraulic principles by incorporating a bypass pathway that allows fluid to flow through the static component. This hydraulic mechanism enables automatic flow rate adjustment based on the dynamic component's position, improving control precision through fluid pressure and flow dynamics rather than mechanical complexity.
2Productivity
If the bypass pathway opens at higher positions, then flow rate control is improved, but energy consumption increases
Solution Approach 1:
The bypass pathway is designed to dynamically open and close based on the dynamic component's position. As the component moves, the relative positioning of the bypass pathway inlet and outlet changes, automatically adjusting the flow rate. This dynamic behavior enables better flow control while minimizing energy consumption by avoiding constant high flow rates.
Solution Approach 2:
The system changes the flow rate parameter automatically by varying the bypass pathway opening based on the dynamic component's position. The bypass pathway provides a variable leakage area that adjusts the flow rate according to operational needs, improving flow control efficiency while reducing overall energy consumption compared to fixed high flow rate systems.
