Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server chassis kits lack expandability and flexibility, making them inefficient in accommodating different hardware configurations and requiring multiple molds for various specifications, which is undesirable for limited spaces.
Innovation Solution
A hard disk rack design featuring a housing with detachable cartridges and battens, allowing for adjustable assembly of hard disk modules with stackable and interchangeable cartridges, reducing the need for multiple molds and enhancing assembly efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional chassis kits are designed for specific rack unit specifications, then the hardware configuration is stable and reliable, but the adaptability and flexibility are poor, requiring multiple molds for different specifications
Solution Approach 1:
The patent applies universality by designing a standardized cartridge structure that can be used across different rack unit specifications (1U, 2U, etc.). The cartridge includes universal components such as the circuit board, connector, and mounting mechanism that remain consistent regardless of the rack size, allowing the same cartridge design to fit multiple configurations without requiring separate molds for each specification.
Solution Approach 2:
The patent segments the hard disk storage system into modular cartridges that can be independently designed and manufactured. Each cartridge is a self-contained unit with its own circuit board and mounting structure, allowing the storage capacity to be scaled by simply adding or removing cartridges rather than redesigning the entire chassis for different specifications.
2Adaptability or versatility
If multiple chassis kits with different dimensions are prepared for various server applications, then the adaptability is improved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The patent reduces manufacturing complexity by establishing a universal cartridge design that can be produced using the same molds and manufacturing processes regardless of the target rack specification. This eliminates the need to maintain separate tooling for 1U, 2U, and other configurations, significantly reducing tooling costs and simplifying the manufacturing supply chain while maintaining flexibility to serve different market segments.
3Stability of the object's composition
If cartridges are fixed within the housing, then the structural stability is improved, but the ease of operation for installation and maintenance is reduced
Solution Approach 1:
The patent implements a dynamic mounting system where cartridges can be easily inserted and removed from the housing through a simplified mechanism. The cartridge includes engagement features that automatically secure it in place during operation, providing stability, while also allowing for quick release and removal when maintenance or upgrades are needed, balancing fixed stability with operational flexibility.

AI summary
A hard disk rack comprises a housing, a plurality of cartridges for receiving a plurality of hard disk modules, and at least one batten. The housing has a bottom, and a plurality of positioning elements disposed on the bottom at intervals. The cartridges are detachably disposed on the bottom in stacks by fastening a fastening portion to the positioning elements of the housing. The batten is pressed against the cartridges for sandwiching the cartridges between the batten and the bottom of the housing, and two opposite ends of the batten are connected to two opposite sidewalls of the housing detachably in order to facilitate the assembly and disassembly of the cartridges conveniently.
