Patent number: 11683921Abstract: An insertion tool for assisting in the insertion of an OCP 3.0 type expansion card in an expansion card slot of a computer system is disclosed. The expansion card may be a pull tab type form factor that does not have a mechanism such as an ejector latch to assist in applying force to insert the card. The expansion card has a front panel opposite a distal edge connector. The tool has a handle and a head coupled to the handle. The head has two contact areas that contact different areas of the front panel of the expansion card. For example, one of the contact areas may be an extended side arm and the other area may be a lateral rib extending from the head.Type: GrantFiled: March 8, 2021Date of Patent: June 20, 2023Assignee: QUANTA COMPUTER INC.Inventors: Yaw-Tzorng Tsorng, Jen-Jia Liou, Jui-Tang Chang

Patent number: 11635791Abstract: A partition for separating computer components in an apparatus holding the computer components is provided. The partition includes a body with a first side and a second side; one or more top tabs projecting from both the first side and the second side of the body; one or more bottom tabs projecting from the first side of the body; and one or more bottom protrusions projecting from the second side of the body. The one or more top tabs are secured in a first manner, e.g., through rivets, to a first panel of the apparatus. The one or more bottom tabs are secured in the first manner to a second panel of the apparatus. The one or more bottom protrusions are secured in a second manner to the second panel of the apparatus, e.g., tucking a protrusion under the second panel. The features allow different-sized compartments for different storage form factors.Type: GrantFiled: August 28, 2020Date of Patent: April 25, 2023Assignee: QUANTA COMPUTER INC.Inventors: Yaw-Tzorng Tsorng, Tung-Hsien Wu, Jui-Tang Chang, Guan-Kai Lien

Publication number: 20210219452Abstract: A front-access chassis for storage drives can be configured to store different drives in different orientations in a single group of drives. For example, drives in a disk group can be installed with two vertical drives followed immediately by four horizontal drives. Each chassis can include multiple disk groups. Thus, drives with certain functions can be easily and readily identified based on orientation. For example, system drives may be installed vertically whereas storage drives may be installed horizontally, permitting a user to quickly identify a desired drive at a glance.Type: ApplicationFiled: January 14, 2020Publication date: July 15, 2021Inventors: Yaw-Tzorng TSORNG, Chen-Chien KUO, Chin-Ho KUO, Jui-Tang CHANG
