Interface Card Module with Enlarged Operational Holes for Tool-Free Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in quickly and easily installing or removing interface card modules from servers due to the lack of clear operational guides and ergonomic design, often requiring additional tools and starting from the wrong position.
Innovation Solution
The interface card module features a support frame with module locks and enlarged operational holes, allowing for single-handed operation and easy installation/removal without tools, using a riser card and card lock mechanism for secure locking and easy disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional interface card modules are used without ergonomic design, then the installation structure is simple, but the ease of operation deteriorates as users cannot quickly locate the operation position or easily operate the locks
Solution Approach 1:
The operation hole is designed with an enlarged opening that exposes a distinct visual indicator to the exterior, allowing users to easily locate and identify the operation position without complex guides or markings. This visual exposure principle enables users to quickly find the correct interaction point on the module.
Solution Approach 2:
The locking mechanism is segmented into movable module locks that can be independently operated through the enlarged operation hole. This segmentation allows users to engage or disengage locks individually, providing intuitive control and ease of operation without requiring complex coordinated actions.
2Ease of operation
If additional tools are required for installation, then the locking mechanism can be more secure, but the ease of operation deteriorates as users need additional tools and cannot perform quick installation
Solution Approach 1:
The module locks are designed to be directly operable through the enlarged operation hole without requiring additional tools. Users can manually engage and disengage the locks by inserting fingers through the hole, making the system self-servicing and eliminating the need for external installation tools.
Solution Approach 2:
The operation hole is pre-configured with an enlarged opening that directly exposes the module locks, allowing users to perform installation or removal actions immediately upon positioning the module. This preliminary exposure of the locking mechanism eliminates the need for additional tool introduction steps.
3Ease of operation
If the operation hole is small, then the structural complexity is low, but the ease of operation deteriorates as users cannot easily insert fingers to operate the locks
Solution Approach 1:
The operation hole incorporates an enlarged opening that creates a distinct visual indicator, making the hole's purpose and location immediately apparent to users. This visual differentiation simplifies the design by eliminating the need for additional markings or complex guidance structures.
Solution Approach 2:
The operation hole is segmented into an enlarged access opening and the internal cavity, allowing direct finger insertion and manipulation of the module locks. This segmentation provides ergonomic access while maintaining a relatively simple overall hole structure without requiring multiple components.

AI summary
In a support frame of an interface card module, two module locks are disposed thereon, both the support frame and the module locks having enlarged operational holes for easy operation for a user. To install the interface card module on a housing of an electronic device, the module locks are pushed and moved by the housing and withstood by the housing. The user may directly operate the module locks through the enlarged holes to disengage the module locks from the housing and to uninstall the interface card module. The interface card module further uses a card lock pivoted on the support frame for locking the interface card at the support frame.
