Solution Overview
Problem
Manual operation of raising and lowering the upper cover of automatic test equipment leads to repetitive strain injuries and increased fatigue for operators, potentially causing errors due to the weight of the cover and repetitive actions.
Innovation Solution
An automatic test equipment system with a first and second control device, a driving device, and transmission members that automatically raise and lower the cover using a stepper motor and timing belt mechanism, along with indicator lights for test results, reducing operator intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to raise and lower the upper cover, then the device structure remains simple, but operator fatigue and injury risk increase due to repetitive actions
Solution Approach 1:
The system uses a driving device with a transmission member to automatically raise and lower the upper cover without requiring manual physical effort. The driving device is controlled by a control device that receives signals from the activating device, enabling the system to serve itself by automating the cover operation and eliminating repetitive manual strain on operators.
2Productivity
If manual operation is used to raise and lower the upper cover, then the device complexity remains low, but work efficiency decreases due to repetitive manual actions
Solution Approach 1:
The patent replaces the manual mechanical operation with an automated driving device that uses a transmission member (such as a belt or chain) connected to a motor or actuator. This substitution eliminates repetitive manual lifting and lowering actions, significantly improving work efficiency while adding only moderate device complexity through the incorporation of the driving and control systems.
3Reliability
If manual operation is used, then the device structure remains simple, but error probability increases due to operator fatigue
Solution Approach 1:
The system incorporates a control device that receives signals from the activating device and automatically controls the driving device to raise and lower the upper cover. This feedback mechanism ensures precise and consistent operation, eliminating errors caused by operator fatigue. The control system monitors and regulates the cover movement, maintaining testing accuracy while adding only necessary control components.

AI summary
An automatic test equipment includes a test apparatus, a first control device, a first assisting device, and a second control device. The test apparatus is applied for testing a first object, wherein the test apparatus has a first cover. The first control device has an activating device. The first assisting device is electrically connected to the first control device. The second control device is electrically connected to the first control device and the test apparatus. When the activating device is activated, the first control device controls the first assisting device to lower the first cover and then the first control device transmits a first control signal to the second control device for allowing the test apparatus to test the first object.
