Expansion Card Lifting Module for Tool-Free Chassis Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices, expansion cards are difficult to install and remove due to limited space, often requiring users to disassemble surrounding components, which complicates the mounting and removal processes.
Innovation Solution
A lifting module with a sidewall bracket, lifting bracket, sliding button assembly, and driven assembly that allows the expansion card to be moved in and out of the chassis without disturbing other components, facilitated by a sliding button assembly that interacts with the driven assembly to control the lifting bracket's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the expansion card is installed directly in the chassis with limited space, then the device structure is compact, but the expansion card cannot be easily installed or removed without disassembling surrounding components
Solution Approach 1:
A lifting module is introduced as an intermediary mechanism between the user and the expansion card. The lifting bracket, controlled via sliding button assembly, acts as a mediator to lift the expansion card upward, creating clearance for easy removal or installation without requiring disassembly of surrounding components
Solution Approach 2:
The lifting module divides the installation/removal process into two independent stages: first lifting the expansion card vertically using the lifting bracket, then allowing horizontal removal or installation. This segmentation separates the lifting function from the insertion/removal function, making the overall process simpler and more convenient
2Stability of the object's composition
If surrounding electronic components are kept in place to maintain device structure, then structural integrity is preserved, but the expansion card becomes blocked and difficult to access
Solution Approach 1:
The lifting module introduces a vertical dimension to the expansion card manipulation. By lifting the expansion card upward in the vertical direction, the system creates access space without requiring horizontal displacement of surrounding components, thus preserving structural integrity while improving accessibility
3Ease of operation
If the expansion card is lifted using a complex mechanical mechanism, then the card can be moved easily, but the device structure becomes more complicated
Solution Approach 1:
The sliding button assembly is designed to be operated from outside the chassis, allowing users to control the lifting mechanism without opening the device. The mechanism serves itself by converting the simple sliding motion of the button into the complex coordinated movements needed to lift and position the expansion card

AI summary
A lifting module for a chassis and an electronic device including the lifting module are provided. The lifting module includes a sidewall bracket, a lifting bracket, a sliding button assembly, and a driven assembly. The sidewall bracket is disposed on a side frame of the chassis. The lifting bracket is movably connected to the sidewall bracket. The sliding button assembly is slidably disposed on the side frame of the chassis. Part of the sliding button assembly is exposed from the chassis. The driven assembly is movably disposed on the sidewall bracket. The driven assembly is connected to interact the sliding button assembly and the lifting bracket. The lifting bracket is driven to move relative to the sidewall bracket selectively by the sliding button assembly through the driven assembly.
