Dolly and Base Apparatus for GPU Board Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of a GPU board into a GPU tray is challenging due to the bulky and heavy nature of the board, which often results in damage to both the board and the tray during maneuvering, especially when navigating through confined spaces with exposed and fragile features.
Innovation Solution
A dolly and base apparatus is used to support and guide the GPU board into the tray, allowing it to be rolled into position without manual lifting, thereby reducing the risk of collision and damage, and facilitating a more controlled and efficient installation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual handling of the heavy GPU board is used, then installer control and flexibility are maintained, but the risk of damage to the board and tray increases due to uncontrolled maneuvering
Solution Approach 1:
The patent introduces a specialized installation apparatus that acts as an intermediary between the installer and the GPU board. This apparatus includes a support structure with rollers that contacts the board, allowing the installer to control the board's movement indirectly through the apparatus rather than direct manual handling. The apparatus translates installer input into controlled, damage-free movement of the heavy board into the tray.
Solution Approach 2:
The patent replaces direct manual mechanical handling with a mechanical assistance system. The installation apparatus uses rollers and support surfaces to substitute for direct human manipulation, providing mechanical advantage and control. This substitution eliminates the need for the installer to directly grip and maneuver the heavy board, reducing damage risk while maintaining operational control.
2Manufacturing precision
If the GPU board is lowered manually into the tray, then installation speed is maintained, but collision with standoffs and damage to components occurs due to imprecise positioning
Solution Approach 1:
The installation apparatus performs preliminary positioning actions before the board makes contact with the tray. The rollers and support structure guide the board into the correct position in advance, ensuring that components like GPUs and connectors are properly aligned before final placement. This preliminary guidance prevents last-minute collisions with standoffs and components.
Solution Approach 2:
The apparatus serves as an intermediary that provides precise positioning control during the insertion process. It includes guided movement paths and support surfaces that ensure the board follows the correct trajectory into the tray, preventing misalignment and collision. This intermediary control mechanism maintains both precision and reasonable installation speed.
3Ease of operation
If metal beams are removed to facilitate board installation, then access to the tray is improved, but reassembly time is increased and production efficiency decreases
Solution Approach 1:
The patent extracts or removes the obstruction (metal beams blocking tray access) temporarily during the installation process. The installation apparatus is designed to work with the tray in its closed configuration, allowing the board to be installed without removing protective beams. After installation, the beams can be quickly reattached, minimizing the time loss compared to traditional methods requiring complete disassembly.
4Reliability
If the GPU board is supported during translation to avoid standoffs, then component damage is prevented, but the complexity of the installation process increases
Solution Approach 1:
The installation apparatus acts as an intermediary support system during the translation phase. It includes support surfaces and rollers that bear the weight of the board and guide it into the tray, automatically preventing contact with standoffs. This intermediary mechanism protects components without requiring the installer to perform complex manual coordination or use multiple tools.

AI summary
An apparatus is provided for loading an electronic device, e.g., a populated GPU board, onto a device tray, e.g., a GPU tray, where the electronic device is cumbersome and the device tray presents obstacles that prevent simply lowering the device into the tray. The apparatus includes a dolly and a base, the base configured to position the dolly against the device tray so that the dolly, carrying the board, may slide the device into position and then be removed from beneath the device.
