Linear Actuator Thrust Testing Device with Lower Counterweights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thrust testing methods for linear actuators are inconvenient and require high working intensity due to the need for counterweights at the upper end, making the movement of counterweights cumbersome and labor-intensive for test operators.
Innovation Solution
A thrust testing device with a frame, supporting legs, a linear actuator mounting plate, a horizontal bearing plate, and counterweight holders on the lower side of the horizontal bearing plate, allowing for accurate thrust testing with reduced operator effort by minimizing the movement height of counterweights and using connecting ropes with guide wheels for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If counterweights are placed at the upper end of the jack for thrust testing, then the thrust can be tested, but the movement of counterweights becomes inconvenient and working intensity of operators increases
Solution Approach 1:
The patent inverts the conventional arrangement by placing counterweights at the lower end of the linear actuator instead of the upper end. The counterweight holders are fixed to the lower end of the jack, and counterweights are suspended downward. This inversion reduces the movement height of counterweights during testing, making operation more convenient while maintaining thrust testing accuracy.
Solution Approach 2:
The patent introduces a vertical dimension for counterweight suspension while maintaining horizontal actuator movement. The counterweight holders are positioned at the lower end, allowing counterweights to hang vertically downward, separated from the horizontal movement path of the actuator jack. This dimensional separation resolves the conflict between measurement accuracy and operational convenience.
2Measurement precision
If counterweights are placed at the upper end of the jack, then thrust testing can be performed, but the movement height of counterweights is large increasing operator workload
Solution Approach 1:
By inverting the counterweight placement from upper to lower end, the patent significantly reduces the vertical distance counterweights must move during thrust testing. The counterweight holders are fixed to the lower end of the jack, minimizing counterweight displacement and thereby reducing both testing time and operator physical effort while preserving measurement precision.
3Device complexity
If counterweight holders are directly fixed below the horizontal bearing plate, then the structure is simple, but the horizontal bearing plate movement causes shaking of counterweight holders affecting test accuracy
Solution Approach 1:
The patent extracts the counterweight holders from direct attachment to the horizontal bearing plate and instead fixes them to the lower end of the linear actuator jack. This separation eliminates the transmission of horizontal movement vibrations from the bearing plate to the counterweight holders, ensuring test accuracy while maintaining reasonable structural simplicity.
Solution Approach 2:
The linear actuator jack serves as an intermediary structure between the horizontal bearing plate and the counterweight holders. The counterweight holders are fixed to the lower end of the jack, which acts as a stable reference point that does not move horizontally with the bearing plate, thereby isolating the counterweights from horizontal vibrations while maintaining structural coherence.
