Test Card Receiving Device for Lateral Exchange and Self-Centering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing test apparatuses for test cards are inefficient in terms of test card exchange, requiring manual disassembly of the contact device for each card change, limiting the number of tests that can be performed in a given time period.
Innovation Solution
The apparatus features a receiving device that can be displaced laterally between a test position and a loading/unloading position, facilitated by actuators, allowing for automated or semi-automated card exchange without disassembling the contact device, and includes guide rails and centering means for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the contact device is manually removed and reattached for each test card exchange, then the test apparatus can be operated, but the test throughput is limited and time is lost
Solution Approach 1:
The receiving device is made movable between a test position (where it holds test cards under the contact device) and a loading/unloading position (where test cards can be accessed from the side). This dynamic repositioning eliminates the need to manually remove and reattach the contact device for each card exchange, thereby increasing test throughput and reducing time loss.
Solution Approach 2:
The test apparatus is divided into functionally independent components: the contact device remains fixed while the receiving device moves independently to access test cards. This segmentation allows the contact device to stay in place during card exchanges, improving productivity without requiring repeated assembly and disassembly.
2Productivity
If the receiving device is made movable for automated card exchange, then test efficiency is improved, but device complexity increases
Solution Approach 1:
The receiving device is equipped with self-centering means that automatically align it with the contact device when moved to the test position. This self-service alignment mechanism reduces the need for complex external positioning systems, thereby improving test efficiency while minimizing the increase in device complexity.
Solution Approach 2:
Guide rails serve as an intermediary mechanism between the movable receiving device and the fixed contact device. The guide rails provide a simple, low-complexity path for the receiving device to follow, enabling automated card exchange without requiring complex positioning or control systems.
3Extent of automation
If the receiving device is displaced laterally for card loading, then automated exchange is enabled, but alignment precision must be maintained
Solution Approach 1:
The receiving device incorporates self-centering means that automatically adjust its position to ensure precise alignment with the contact device after lateral displacement. This self-adjustment capability enables automated card exchange while maintaining the necessary alignment precision without requiring complex external positioning systems.
Solution Approach 2:
Manual alignment operations are replaced with automated self-centering mechanisms. The self-centering means use mechanical guidance features (such as tapered guides or cam mechanisms) to automatically position the receiving device correctly, eliminating the need for manual alignment while ensuring precision.
