Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The disk drive industry faces challenges with thin profit margins due to commoditization and competition from solid state drives, leading to a need for innovative server configurations that can efficiently utilize hard disk drives (HDDs) while reducing costs.
Innovation Solution
A server system comprising a plurality of dummy HDDs that share a common set of universal disk drive components, including a master components module which provides missing chipset functionality and two-pole voice coil magnets, allowing multiple dummy HDDs to function as complete HDDs, thereby reducing the need for individual chipsets and lowering costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional HDD configurations with individual chipsets are used, then each drive functions independently, but manufacturing costs increase and profit margins decrease
Solution Approach 1:
The patent implements a universal controller card that can control multiple dummy HDDs simultaneously. The controller card serves as a shared resource that provides chipset functionality to multiple drives, eliminating the need for individual chipsets in each dummy HDD. This multi-functional approach reduces manufacturing costs while maintaining operational capability through the shared control mechanism.
Solution Approach 2:
The patent combines multiple HDD control functions into a single controller card that can manage multiple dummy drives. By merging the chipset functionality into one shared component rather than having separate chipsets for each drive, the system reduces overall component count and manufacturing complexity while maintaining independent drive operation through logical separation.
2Ease of manufacture
If dummy HDDs share common components, then cost is reduced, but system reliability may be affected by shared component failure
Solution Approach 1:
The patent segments the HDD system into dummy drives (containing only mechanical components) and a separate universal controller card (containing electronic control functions). This segmentation allows the controller to be shared among multiple drives while keeping the drive mechanics independent. The logical separation maintains reliability by allowing individual drive operation to be managed independently through the shared controller.
Solution Approach 2:
The universal controller card acts as an intermediary between the host system and multiple dummy HDDs. It mediates all control and data operations, translating host commands into drive-specific actions. This intermediary approach allows multiple drives to share control resources while maintaining independent operational paths, reducing cost without compromising reliability.
3Adaptability or versatility
If individual chipsets are installed in each HDD, then drive functionality is complete, but server production cost increases
Solution Approach 1:
The universal controller card provides complete chipset functionality for multiple dummy HDDs simultaneously. Rather than requiring separate chipsets in each drive, one universal controller delivers all necessary control, data, and power management functions to multiple drives, maintaining full functionality while reducing component proliferation and manufacturing cost.
Solution Approach 2:
The patent creates multiple dummy HDDs that are essentially copies of the basic drive mechanism without individual chipsets. These copied drive units share a common controller, eliminating the need to replicate expensive chipset components in each drive while maintaining functional equivalence through the shared control architecture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enables cost-effective server systems by sharing chipsets among multiple dummy HDDs, reducing the overall cost of server production and maintaining data storage functionality, while also simplifying manufacturing and reducing reliance on expensive components.
Implementation Method 1
The voice coil magnet 2 is a strong hard-magnet, which is typically made from a neodymium, with a north pole side (+) and a south pole side (−) that facilitates actuating the HSA 17 across the magnetic disk 10 depending on how current is moving through the voice coil wire (not shown)
Implementation Method 2
a magnetic HDD 99 fundamentally retains or otherwise stores digital data to a magnetic disk 10 via a magnetic recording head 8 that writes data tracks 14 while the disk is spinning under the magnetic recording head 8
Implementation Method 3
one or more magnetic disks 10 are stacked over a spindle motor 12 attached to the base-plate 18
Implementation Method 4
a magnetic recording head 8 is retained in constant pressure on the disk surface by a head suspension 6 that is swaged on the end of an E-block 16
Data Source
AI summary
A server box embodiment is disclosed that generally comprises an array of dummy HDDs that share a common set of universal disk drive components in a master components module, or power module. Each dummy HDDs is constructed without expensive onboard chipsets that control the normal functionality of a standard HDD. By sharing expensive chipsets in a master components module (power module) money can be saved in building and selling the dummy HDD server. Embodiments envision a power module possessing the needed chipset functionality that is missing in a dummy HDD. The power module can be made to move from dummy HDD to dummy HDD supplying the necessary chipset in a shared manner when data is being stored or retrieved for client or end-user.
