Solution Overview
Problem
In compact blade server chassis, the limited space and restricted airflow pose challenges for adequate cooling and full functionality of components like hard disk drives, processors, and memory, requiring compromises in design to maintain performance.
Innovation Solution
The implementation of hinged hard disk drive carriers that rotate between open and closed positions within the server chassis, allowing for optimized placement and airflow while maintaining accessibility for hot swapping, ensuring proper cooling and full system capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If hard disk drives are installed in a compact blade server chassis, then space utilization is improved, but airflow and cooling are worsened
Solution Approach 1:
The hard disk drive carrier is made rotatable about a hinge axis, allowing it to dynamically change position between a first position (extending beyond the front of the chassis) and a second position (within the chassis). This dynamic positioning enables optimization of both space utilization and airflow/cooling depending on operational requirements.
Solution Approach 2:
The solution introduces a rotational dimension to the hard disk drive carrier installation, moving from a fixed linear arrangement to a multi-positional rotational arrangement. This allows the carrier to access different spatial configurations, improving both compactness and cooling airflow by utilizing the rotational degree of freedom.
2Ease of operation
If hard disk drives are made accessible for hot swapping, then ease of operation is improved, but physical space and airflow are worsened
Solution Approach 1:
The rotatable carrier provides dynamic accessibility - the hard disk drives can be easily accessed for hot swapping when the carrier is in the first position (extending beyond the front), while maintaining compact integration when in the second position (within the chassis). This resolves the contradiction by making accessibility a controllable state rather than a fixed constraint.
3Adaptability or versatility
If components are arranged to maximize functionality, then device capability is improved, but air flow and cooling are worsened
Solution Approach 1:
The rotatable carrier allows the system to dynamically adjust between maximizing functionality (carrier within chassis for compact integration) and optimizing airflow (carrier extending beyond front for better air access). This dynamic adjustment resolves the contradiction between functionality and cooling efficiency.

AI summary
A system comprises a server chassis and first and second hard disk drive carriers, wherein each carrier supports a hard disk drive. A first hinge rotatably connects a distal end of the first hard disk drive carrier to a first side of the chassis, wherein the first hinge allows the carrier to rotate about a first hinge axis between an open position and a closed position. The first hard disk drive carrier rotates in a first plane between an open position extending beyond the front of the chassis and a closed position within the chassis. A second hinge rotatably connects a distal end of the second hard disk drive carrier to a second side of the chassis that opposite the first side of the chassis, wherein the hinge allows the carrier to rotate about a second hinge axis between an open position and a closed position. The second hard disk drive carrier rotates in a second plane between an open position extending beyond the front of the chassis and a closed position within the chassis, wherein the second plane is parallel to the first plane.
