Computer Chassis Carrying Frame for Tool-Free ODD Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional computer chassis designs make it difficult to assemble or disassemble an optical disc drive (ODD) without specialized tools, due to the structural configuration of the chassis.
Innovation Solution
The computer chassis incorporates a carrying frame with pivotal shafts and an abutting structure, allowing the ODD to be detachably assembled and easily assembled or disassembled by adjusting the carrying frame to different arrangement angles, thereby preventing interference with the front plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional chassis structural configuration is used, then the chassis structure is simple and stable, but the ODD becomes difficult to assemble or disassemble and requires specialized tools
Solution Approach 1:
The carrying frame is divided into separate components including pivotal shafts, abutting structures, and drive mechanisms that can independently move between arrangement angles. This segmentation allows the ODD assembly to be detached without affecting the overall chassis structure, enabling tool-free assembly and disassembly while maintaining chassis simplicity
Solution Approach 2:
The carrying frame is designed with dynamic movement capability, allowing it to switch between multiple arrangement angles (first, second, and third angles) through pivotal shafts rotating in sliding slots. This dynamic adjustment enables the frame to move from a storage position to an operational position flush with the panel, providing ease of operation without permanent structural modification
2Ease of operation
If the carrying frame is positioned at the first arrangement angle for detachment, then the ODD can be separated from the chassis, but the pivotal shafts may interfere with the front plate during movement
Solution Approach 1:
The abutting structure is designed to preliminarily contact the front plate before the pivotal shafts complete their movement to the first arrangement angle. This preliminary action guides the movement path and ensures that the shafts rotate smoothly within the sliding slots without colliding with or interfering with the front plate, enabling safe detachment
Solution Approach 2:
The sliding slots act as intermediary guides between the pivotal shafts and the front plate. These slots constrain the movement path of the shafts, allowing them to rotate from the second arrangement angle to the first arrangement angle while preventing direct contact or interference with the front plate, thus enabling safe detachment
3Shape
If the carrying frame is positioned at the third arrangement angle, then the ODD surface is flushed with the panel for a clean appearance, but the frame requires precise positioning
Solution Approach 1:
The abutting structure is designed to contact the front plate at a predetermined position that corresponds to the third arrangement angle. This beforehand cushioning provides a mechanical stop that automatically positions the carrying frame at the correct angle, ensuring the ODD surface is flush with the panel while compensating for minor manufacturing tolerances without requiring high-precision positioning

AI summary
A computer chassis includes a chassis, a panel covering a front plate of the chassis, a carrying frame assembled to two lateral plates of the chassis, and an optical disc drive (ODD) that is assembled to the carrying frame. The carrying frame has a first arrangement angle, a second arrangement angle, and a third arrangement angle with respect to the chassis. When the carrying frame is at the first arrangement angle, the carrying frame is detachable from the chassis. When the carrying frame is at the second arrangement angle, the carrying frame abuts against the front plate and is movable away from the front plate. When the carrying frame is at the third arrangement angle, the carrying frame is movable toward the front plate and a surface of the ODD is flushed with the panel through an opening of the panel.
