Add-In Card Mount Assembly for Toolless Access in Tight Chassis

The patent applies the dynamics principle by designing a movable tray that can slide between a first position (inserted into the narrow space) and a second position (withdrawn from the narrow space). The tray is coupled to a handle that users can manipulate to move the tray along a sliding path. This dynamic mechanism allows the add-in card to be accessed in a compact configuration while enabling easy installation and removal operations by moving the tray to the second position, thereby resolving the contradiction between space utilization and ease of operation.

The patent applies the segmentation principle by dividing the mounting structure into separate functional components: a base plate fixed to the device, a movable tray that holds the add-in card, and a handle for actuation. This segmentation allows the tray to be independently moved along a sliding path between inserted and withdrawn positions. By separating the card-holding function (tray) from the fixed mounting structure (base plate), the design maintains compactness while enabling easy maintenance access through the movable tray mechanism.

The patent transforms the fixed mounting structure into a dynamic system by introducing a movable tray that can slide between inserted and withdrawn positions along a defined path. The tray is coupled to a handle that users can manipulate to achieve movement. This dynamic design maintains relatively simple structural elements (base plate, tray, handle) while providing the flexibility needed for easy installation and removal operations, resolving the contradiction between structural simplicity and installation flexibility.
