Electrical Testing Equipment with Adjustable Rails for Fixture Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in electrical testing equipment is to improve testing efficiency and reduce misplacement errors during fixture assembly, particularly when placing the upper fixture after the lower fixture is initially positioned.
Innovation Solution
The electrical testing equipment incorporates conveyor rails with a first moving device that adjusts the distance between the rails and the supporting surface, allowing the upper and lower fixtures to be placed together, and uses rollers to support the fixture assembly during placement, enabling easy alignment without contacting the supporting surface.

Engineering Contradiction Analysis
1Productivity
If the upper fixture is placed after the lower fixture is initially positioned, then the fixture assembly can be assembled in sequence, but the efficiency of placing the fixture assembly is reduced and misplacement errors may occur
Solution Approach 1:
The conveyor rails are preliminarily adjusted to a maximum distance state before the fixture assembly is placed. This preliminary preparation creates sufficient space for the entire fixture assembly to pass through and be positioned in one operation, eliminating the need for sequential placement and preventing misplacement errors.
Solution Approach 2:
The conveyor rails are made dynamically adjustable in distance through the first moving device. This dynamic adjustment capability allows the system to adapt between a maximum distance state during placement (for efficiency) and a smaller distance state during operation (for normal testing), resolving the contradiction between placement efficiency and operational requirements.
2Ease of operation
If the conveyor rails are fixed at a small distance, then the operational space is compact, but the fixture assembly cannot pass through for placement
Solution Approach 1:
The conveyor rails incorporate a moving device that enables dynamic adjustment of the distance between rails. This allows the system to switch between a compact state for normal operations and an expanded state for fixture assembly placement, satisfying both requirements at different operational phases.
Solution Approach 2:
Before placing the fixture assembly, the conveyor rails are preliminarily adjusted to maximum distance to create sufficient passage space. After placement is complete, the rails can be adjusted back to a compact configuration for normal operations, thus achieving both placement capability and operational compactness.
3Ease of manufacture
If the upper and lower fixtures are placed separately in sequence, then the assembly process is straightforward, but misplacement errors occur and efficiency is reduced
Solution Approach 1:
The conveyor rails are preliminarily adjusted to maximum distance before placement, creating sufficient space for the entire fixture assembly to pass through simultaneously. This preliminary preparation enables one-step placement of both fixtures together, improving efficiency while maintaining simplicity through the straightforward adjustment- placement sequence.

AI summary
An electrical testing equipment includes a machine, a pair of conveyor rails and a first moving device. The machine has a supporting surface. The supporting surface is configured to support a fixture assembly. The conveyor rails are configured to deliver a device under test. The conveyor rails are separated from the supporting surface by a distance. The first moving device is disposed on the machine and connected with the conveyor rails. The first moving device is configured to move the conveyor rails relative to the machine to change the distance.
