Modular Information Handling Resource Tool for Safe DIMM Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for handling modular information handling resources, such as DIMMs, require significant force for installation, which can cause discomfort and lead to non-compliant installation practices that risk damaging the components due to the need for precise alignment and force application.
Innovation Solution
A tool with a drive portion and two mechanically coupled fingers that apply forces to opposite side edges of a modular information handling resource, allowing it to be securely engaged and then released when the retention force of a connector exceeds these forces, facilitating safe and ergonomic handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If high force is applied to install the DIMM module, then the DIMM can be installed into the slot connector, but it may cause pain or discomfort to the individual and lead to non-compliant installation
Solution Approach 1:
A tool is introduced as an intermediary between the operator and the DIMM module. The tool includes a drive portion that contacts the DIMM and fingers that the operator manipulates, allowing force application without direct hand contact with the DIMM edges. This mediator enables compliant installation while protecting the operator from discomfort and the DIMM from damage.
Solution Approach 2:
The tool is segmented into distinct functional parts: a drive portion for contacting the DIMM module, fingers for operator manipulation, and a release mechanism. This segmentation allows the force application function to be separated from the operator's direct interaction, enabling precise force control that complies with JEDEC specifications while maintaining operator comfort.
2Force
If high force is applied to install the DIMM module, then the installation can be completed, but it may result in damage to traces of the edge connector or electrical contacts of the slot connector
Solution Approach 1:
The tool acts as a protective intermediary that distributes and controls the installation force. The drive portion contacts the DIMM at safe locations (not on vulnerable edges), and the tool's structure ensures force is applied uniformly along the DIMM length, preventing concentration of stress that could damage traces or electrical contacts.
Solution Approach 2:
The tool design incorporates protective features that cushion against excessive force before it reaches the DIMM and slot connector. The fingers and drive portion geometry are designed to limit maximum force application, and the tool naturally complies with JEDEC specifications, providing built-in protection against damage before installation occurs.
3Ease of operation
If the tool applies force to the information handling resource, then safe handling is achieved, but the retention force of the connector must overcome this force to release the resource
Solution Approach 1:
The release mechanism is designed to be self-actuating. When the operator removes the tool from the DIMM, the spring automatically returns the fingers to their original position, causing the DIMM to be released from the tool by the connector's retention force. This self-service mechanism eliminates the need for additional force application during release.
Solution Approach 2:
The spring mechanism provides a counterbalancing force that opposes the force applied during installation. During removal, this spring force assists the connector's retention force in releasing the DIMM from the tool, reducing the net force requirement for the release operation while maintaining safe handling during installation.

AI summary
A tool for handling a modular information handling resource may include a drive portion, a first finger mechanically coupled to the drive portion, the first finger configured to apply a first force to a first side edge of the information handling resource when the information handling resource is engaged with the tool, and a second finger mechanically coupled to the drive portion, the second finger configured to apply a second force to a second side edge of the information handling resource opposite from the first side edge when the information handling resource is engaged with the tool. When the information handling resource is coupled to a connector via a bottom edge of the information handling resource adjacent and perpendicular to the side edges, a retention force applied by the connector to the information handling resource overcomes the first and second forces such that the tool releases the information handling resource.
