Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional chassis designs are unable to adapt to changing dimensions of IT components, necessitating replacement and causing downtime and increased costs due to the need for new chassis assemblies, which disrupts IT infrastructure availability.
Innovation Solution
A chassis node coupling system with a latch assembly and coupling assemblies that allow for releasable coupling of chassis nodes of varying sizes to a chassis assembly, enabling online upgrades without disrupting the computing device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional chassis designs are used, then the chassis structure is simple and fixed, but the chassis cannot adapt to changing dimensions of upgraded IT components, requiring complete replacement and causing downtime
Solution Approach 1:
The chassis is divided into a fixed portion and a movable extension portion that can be independently adjusted. The extension portion includes a chassis node that can be moved along the chassis assembly and locked at different positions, allowing the overall chassis length to be adapted to different component dimensions without replacing the entire chassis structure.
Solution Approach 2:
The chassis design transitions from a static fixed-length structure to a dynamic adjustable-length structure. The movable extension portion can be extended or retracted along the chassis assembly and secured at various positions using the latch assembly, enabling the chassis to dynamically adapt to different component size requirements.
2Adaptability or versatility
If traditional fixed-size chassis are used, then manufacturing is simple, but upgraded components requiring different dimensions necessitate complete chassis replacement, increasing costs and complexity
Solution Approach 1:
The chassis is segmented into a fixed base portion and a movable extension portion with independent adjustment capability. This segmentation allows the majority of the chassis structure to remain simple and standardized while only the extension portion requires additional adjustment mechanisms, balancing adaptability with structural simplicity.
Solution Approach 2:
The movable extension portion serves multiple functions: it extends the chassis length to accommodate larger components, provides adjustment mechanisms for different component sizes, and maintains electrical connections throughout the adjustment range. This multi-functionality reduces the need for multiple different chassis designs.
3Adaptability or versatility
If chassis nodes are coupled rigidly to the chassis assembly, then structural stability is high, but the chassis cannot accommodate varying component dimensions without complete replacement
Solution Approach 1:
The coupling mechanism transitions from a rigid fixed-position connection to a dynamic adjustable connection. The latch assembly allows the chassis node to be positioned at different locations along the chassis assembly while maintaining secure coupling, providing both adaptability and stability through controlled mechanical engagement.
Solution Approach 2:
The latch assembly acts as an intermediary mechanism between the chassis node and the chassis assembly. It provides a controlled coupling interface that allows for positional adjustment while maintaining secure attachment, mediating between the need for flexibility in positioning and the need for stable coupling.

AI summary
A chassis node coupling system includes a chassis node configured to be received at a first end of a chassis assembly, wherein the chassis node size exceeds the chassis assembly size. A latch assembly with one or more coupling assemblies may be configured to releasably couple the chassis node to the chassis assembly.
