Carrierless Drive Insertion Guide System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of carriers in data storage enclosures for drive insertion, retention, and removal increases costs and complexity, especially in high-density designs, due to additional integration charges and unique field-replaceable units, as well as special shipping requirements.
Innovation Solution
A carrierless system utilizing a guide system with opposing guide walls and a slidable member that includes lifting and retention features, allowing for the secure insertion, retention, and removal of data storage devices without the need for carriers, using compliant guide features to prevent vibration and rattling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If carriers are used for drive insertion, retention, and removal, then drive security and ease of operation are improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent extracts the carrier component from the system entirely, replacing it with a carrierless design where the data storage device is directly retained by the guide system. The guide features and slidable members provide retention functionality without requiring a separate carrier, thereby eliminating the complexity and cost of carrier integration while maintaining ease of operation.
Solution Approach 2:
The guide system components serve multiple functions: the guide walls provide structural support and alignment, the guide features provide retention and positioning, and the slidable members enable both insertion guidance and retention release. This multi-functionality replaces the specialized carrier component, reducing overall system complexity while maintaining operational ease.
2Reliability
If carriers are used for high-density drive designs, then drive retention is improved, but manufacturing costs and integration complexity increase
Solution Approach 1:
The carrier component is removed from the system, and its retention function is redistributed to the guide features and slidable members. This eliminates the need for separate carrier manufacturing and integration, reducing manufacturing costs while maintaining reliable drive retention through the guide system's direct retention mechanism.
Solution Approach 2:
The retention function previously performed by the carrier is merged into the guide system components. The guide features and slidable members work together to provide retention, combining multiple functions into integrated structures that reduce the number of separate components and lower manufacturing costs.
3Adaptability or versatility
If carriers are used for field-replaceable units, then drive replaceability is improved, but device complexity and shipping requirements increase
Solution Approach 1:
The carrier is extracted from the field-replaceable unit structure, allowing the data storage device to be directly installed and replaced in the guide system. This simplifies the FRU structure by eliminating the carrier layer, reducing device complexity while maintaining the ability to easily replace drives in the field.

AI summary
An apparatus includes a guide system having first and second opposing guide walls with guide features extending from the first and second guide walls. The guide features support a data storage device when the data storage device is positioned between the first and the second opposing guide walls. The apparatus also includes a slidable member operably coupled to the first guide wall. The slidable member includes a top portion having retention features and a bottom portion having a lifting member. The lifting member enables lifting of the data storage device by the slidable member when the data storage device is within the guide system. The slidable member further includes a bent latch-release portion between the top portion and the bottom portion. The bent latch-release portion biases the data storage device towards the second guide wall.
