Adjustable Modular Server Chassis Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server chassis lack standardization in length, requiring multiple chassis of different sizes to accommodate servers of varying lengths, causing inconvenience and increased costs for users.
Innovation Solution
A modular server chassis with adjustable length, comprising a first casing module, a second casing module, and a back plate module, where the second outer box can slide relative to the first outer box, allowing for adjustable length and accommodating different server lengths through a system of fixing holes and slots, enabling easy assembly and replacement of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple chassis with different sizes are purchased to accommodate servers of different lengths, then all server length requirements are met, but cost and device complexity increase
Solution Approach 1:
The chassis is divided into multiple modular segments (first chassis segment, second chassis segment, third chassis segment) that can be selectively assembled. Each segment has standardized interfaces with fixing holes and fixing pieces that allow flexible combination. This segmentation enables a single modular chassis design to replace multiple fixed-size chassis, reducing device complexity while maintaining adaptability to different server lengths.
Solution Approach 2:
The modular chassis segments are designed with universal interfaces (fixing holes arranged in arrays, standardized fixing pieces) that allow the same components to serve multiple functions. The first chassis segment can pair with different second chassis segments, and power supply units can be installed in various positions. This universality enables one modular chassis design to accommodate multiple server configurations, eliminating the need for multiple specialized chassis types.
2Device complexity
If a fixed-size chassis is used, then device complexity is reduced, but adaptability to different server lengths is lost
Solution Approach 1:
The chassis transitions from a fixed structure to a dynamic, reconfigurable structure. The modular segments can be assembled and disassembled, and the second chassis segment can slide relative to the first segment along the sliding direction. This dynamic capability allows the chassis length to be adjusted based on server requirements while maintaining relatively simple individual segment designs, thus preserving device complexity benefits while gaining adaptability.
Solution Approach 2:
The second chassis segment is disposed within the first chassis segment in a nested configuration, with the second segment capable of sliding along the first segment. This nesting arrangement allows flexible length adjustment while keeping the overall structure compact and manageable. The power supply units are also nested within the modular segments, enabling flexible positioning without increasing overall structural complexity.

AI summary
A modular chassis includes a first casing module, a second casing module and a back plate module. The second casing module and the back plate module are disposed inside the first casing module. The first casing module includes a first outer box and a second outer box, in which the second outer box is capable of sliding relative to the first outer box and joining to the first outer box such that the length of the first casing module is adjustable.
