Specification

Description:Field of the Invention


The present disclosure generally relates to actuator systems. Further, the present disclosure particularly relates to a fluid-actuated actuator system for regulating fluid flow.
Background
The background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
Fluid-actuated actuator systems are commonly used in various industrial and mechanical applications. Such systems typically involve a combination of channels, valves, and pressure sensors that enable fluid transport and control. However, conventional fluid-actuated actuator systems face several challenges. Various systems are known for employing rigid channel structures that lack flexibility, thereby limiting the adaptability of the actuator system in environments requiring dynamic fluid control. Rigid structures often result in inefficient fluid transport, leading to delays in response time and increased operational costs. Such systems are also prone to clogging and blockages due to the use of narrow channels, which further exacerbates inefficiencies and increases maintenance requirements.
Another commonly known method for fluid control involves the use of external valves and pressure regulators to manage the flow of fluids. In such systems, separate components are utilized for fluid transport, flow regulation, and pressure sensing. However, said systems suffer from high complexity due to the requirement of multiple external components. The integration of such external components leads to increased system size, weight, and cost. Moreover, the dependence on multiple discrete elements increases the likelihood of component failure, resulting in reduced overall system reliability. Such systems are also limited in terms of precision control due to lag in communication between the separate components, which further results in inaccuracies during fluid regulation.
Furthermore, actuator systems employing traditional valves and sensors often struggle with energy efficiency. Known systems tend to consume high amounts of energy to maintain fluid flow and regulate pressure. This problem is exacerbated in applications where fluid flow needs to be continuously monitored and adjusted. Additionally, conventional systems often exhibit uneven distribution of activation energy across the actuator system, leading to inconsistent fluid flow and irregular pressure levels. Such inconsistencies adversely impact the overall performance of fluid-actuated systems, particularly in applications where high accuracy and reliability are required.
Moreover, traditional pressure sensors used in fluid-actuated systems face challenges with regard to placement and alignment. Sensors are often positioned in locations that result in suboptimal pressure monitoring, leading to inaccurate readings and poor regulation of fluid flow. Misalignment of pressure sensors can cause delays in detecting pressure changes, reducing the effectiveness of the actuator system. In applications where rapid response to pressure fluctuations is critical, such delays can lead to system failure or malfunction.
Additionally, the use of bulky control systems for fluid management has been a persistent drawback in known fluid-actuated actuator systems. The large size of control units adds to the overall complexity and space requirements of the system. Said bulkiness often makes said systems unsuitable for compact or portable applications, where space constraints are a significant concern. The heavy reliance on external control units also hinders the ability to achieve high precision in fluid control, especially in applications requiring real-time adjustments.
In light of the above discussion, there exists an urgent need for solutions that overcome the problems associated with conventional systems and/or techniques for fluid-actuated actuator systems.
