[0002] Unused travel, also known as play, is the ineffective movement that occurs when the hinge rotates; it's the gap where the hinge itself doesn't immediately move the screen or other components when rotated. This can affect the user experience of a laptop, causing issues such as screen wobbling or a loose hinge.

[0003] The current industry standard for detecting misalignment is generally a manual inspection method. Specifically, a plumb bob fixture is used for inspection, and the operation process is as follows: 90 degrees (starting position) → 180 degrees → 135 degrees (place the push-out positioning rod on the positioning rod) push the positioning rod back to allow the plumb bob to slide down naturally → push out the positioning rod at 141 degrees (confirm whether the plumb bob angle exceeds the 141-degree positioning rod; if it does not exceed, it is an OK product; if it exceeds, it is an NG product). Manual inspection requires visual inspection to see if the plumb bob rod interferes with the positioning rod, as there is an error involved. Utility Model Content
