Actuator Detachable Guide Mechanism Axial Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing actuators lack stability and rigidity in displacing a displaceable body along an axial direction, especially when handling varying loads, as they do not have a detachable guide mechanism that can be optimized based on the load size.
Innovation Solution
A detachable guide mechanism is introduced, comprising a main body portion, guide shafts, and a connecting member that interconnects the guide shafts and the displaceable body, allowing for stable displacement along the axial direction and enhanced rigidity by using guide rods and a connecting plate to guide the piston rod.

Engineering Contradiction Analysis
1Stability of the object's composition
If a guide mechanism is integrated into the actuator body, then stability and rigidity during displacement are improved, but the actuator size and weight increase
Solution Approach 1:
The guide mechanism is separated from the actuator body as an independent detachable unit. This segmentation allows the guide mechanism to be added only when needed for stability, rather than being permanently integrated into the actuator structure, thereby reducing the base actuator weight while maintaining stability when required.
Solution Approach 2:
The guide mechanism is designed to be detachably attachable and removable from the actuator body. This dynamic configuration allows the system to adapt between a compact lightweight state (without guide mechanism) and a stable reinforced state (with guide mechanism), optimizing the trade-off between weight and stability based on operational requirements.
2Strength
If a guide mechanism is added to enhance rigidity, then resistance to perpendicular loads is improved, but device complexity increases
Solution Approach 1:
The guide mechanism is designed as a separate modular unit with standardized attachment interfaces. This segmentation reduces the complexity of integrating guidance functionality into the actuator, as the guide mechanism can be independently designed, manufactured, and attached without redesigning the entire actuator structure.
Solution Approach 2:
The detachable guide mechanism can be universally applied to different actuator models using standardized attachment interfaces. This multi-functionality allows a single guide mechanism design to serve multiple purposes across different actuator configurations, reducing overall system complexity rather than requiring custom guide mechanisms for each actuator variant.
3Force
If the actuator is designed for large loads, then load handling capability is improved, but the actuator size increases
Solution Approach 1:
The actuator system allows dynamic configuration where the guide mechanism (which provides load handling capability) can be attached only when large loads are anticipated. This enables the actuator to operate in a compact lightweight mode for small loads and transition to a high-capacity mode when needed, optimizing the balance between size and load handling capability.
Solution Approach 2:
By separating the guide mechanism from the actuator body, the load handling components can be added independently based on actual load requirements. This segmentation prevents the need to oversize the entire actuator for maximum load capacity, allowing the base actuator to remain compact while the detachable guide mechanism provides the necessary load handling capability when attached.

AI summary
An actuator is equipped with a cylinder body in the interior of which a piston is disposed for displacement therein. A piston rod connected to the piston projects outwardly to the exterior from an end of the cylinder body. A guide unit, having a guide body that is attached to the cylinder body, and a pair of guide rods, which are disposed displaceably with respect to the guide body, are disposed detachably on the cylinder body. Additionally, by mutually interconnecting the guide rods of the guide unit and the piston rod through a connecting plate, when the piston rod is displaced in an axial direction, the piston rod is guided by the pair of guide rods.
