Testing Machine Damper for Probe Velocity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional testing machines often result in unstable probe movement and potential damage to either the probe or the device under test due to rapid speed, leading to impact issues during contact.
Innovation Solution
A testing machine equipped with a damper that restricts the velocity of the probe as it touches the device under test, using a control lever and temporary positioning mechanism to ensure slow and precise contact, minimizing impact and damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the lifting platform moves quickly to improve testing efficiency, then productivity increases, but the impact force increases causing potential damage to the probe or device under test
Solution Approach 1:
The damper is pre-installed on the lifting platform and automatically activates when the probe approaches the device under test. It provides cushioning force before contact occurs, reducing impact damage while allowing quick approach movements for maintained productivity.
Solution Approach 2:
The damper acts as an intermediary element between the lifting platform and the probe. It mediates the force transmission by absorbing excess energy during rapid approach, allowing fast movement while protecting against impact damage.
2Ease of operation
If the operator manually controls the lever to improve ease of operation, then ease of operation increases, but the movement speed becomes unstable causing unreliable positioning
Solution Approach 1:
The damper provides automatic feedback-based speed regulation. When the probe approaches the device under test, the damper engages and automatically reduces speed, eliminating the need for operator skill adjustments while maintaining easy manual control for positioning.
Solution Approach 2:
The damper is a self-regulating device that automatically adjusts the lifting speed based on the proximity to the device under test. It serves itself by using the mechanical compression of the probe approach to trigger the damping effect, eliminating reliance on operator skill for speed control.
3Object-affected harmful factors
If the probe moves slowly to reduce impact, then impact force decreases, but the testing time increases reducing productivity
Solution Approach 1:
The damper creates a periodic motion pattern during probe approach: fast movement during most of the approach, then automatic slowing when the damping element engages near the contact point. This periodic speed variation reduces impact force while minimizing total testing time.
Solution Approach 2:
The damper applies preliminary opposing force to the downward motion of the probe before contact occurs. This preliminary anti-action reduces the velocity just in time to prevent impact damage, while allowing rapid movement during the majority of the approach phase.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The damper effectively reduces the probe's velocity upon contact, preventing heavy impacts and ensuring the probe and device under test are not damaged, allowing for precise and safe interactions.
Implementation Method 1
the damper at least partially abuts against the control lever or the probe platform, so as to reduce a velocity of the probe moving towards the device under test

AI summary
A test machine includes a base, a testing platform, a probe platform, a control lever, a temporary positioning mechanism and a damper. The testing platform connects with the base and carries a device under test. The probe platform connects with the base and moves along a longitudinal direction. The probe platform connects with a probe. The control lever connects with the base and the probe platform which is driven by the control lever to move along the longitudinal direction. The temporary positioning mechanism connects with the control lever and temporarily holds the probe platform and the control lever at a specific position. The damper connects with the base. When a distance between the probe and the DUT is shorter than a buffering distance, the damper abuts against the control lever or the probe platform to reduce a velocity of the probe moving towards the DUT.
