Server Chassis Roller-Based Support to Prevent Load Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server chassis positioning structures deform or experience gap changes due to weight loads, leading to potential interference between upper and lower chassis, especially when loaded with multiple hard disks.
Innovation Solution
The proposed solution includes a supporting and positioning structure with a metal mounting plate, a supporting body featuring parallel plates and a rotatable roller, which reduces friction and maintains chassis distance, preventing interference and facilitating easy extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If positioning structures such as hooks are used to position chassis in the cabinet, then the chassis can be positioned after being pushed into the cabinet, but the positioning structures will be deformed or the gaps between the chassis will be changed due to the weight load
Solution Approach 1:
The positioning function is divided into two independent parts: the supporting body that bears the weight load and the positioning structure that maintains chassis position. The supporting body includes a base and supporting plates that are separately configured from the positioning hooks, allowing the positioning function to be independent from the load-bearing function.
Solution Approach 2:
A supporting body is introduced as an intermediary component between the chassis and the cabinet. This supporting body includes supporting plates that extend toward the cabinet and work together with positioning structures to provide both support and positioning functions, preventing direct load on the positioning hooks.
2Quantity of substance
If the chassis is designed to accommodate multiple hard disks, then the storage capacity is increased, but the chassis weight increases causing deformation of positioning structures and potential interference between upper and lower chassis
Solution Approach 1:
The supporting body is designed to counterbalance the weight of the chassis by providing a rigid support structure with supporting plates that extend toward the cabinet. This support structure compensates for the increased weight from multiple hard disks, preventing deformation of positioning structures and maintaining proper spacing between chassis.
3Ease of operation
If the chassis is extracted by pushing and pulling, then the operation is simple, but the friction between the chassis and cabinet is high making extraction difficult
Solution Approach 1:
A roller is disposed between the supporting body and the cabinet to replace direct sliding contact with rolling contact. The roller reduces friction significantly, allowing the chassis to be extracted more easily while maintaining the simple push-pull operation method.
4Reliability
If positioning structures are used to maintain chassis position, then the chassis can be positioned in the cabinet, but the gaps between chassis may change due to load causing interference between upper and lower chassis
Solution Approach 1:
The positioning function is segmented from the load-bearing function. The supporting body with supporting plates handles the load-bearing to maintain stable gaps, while separate positioning structures handle the positioning. This segmentation ensures that positioning stability is not compromised by weight-induced deformations.

Function Achieved in This Case
This solution effectively maintains chassis position, reduces wear, and enhances the extraction process by minimizing friction between the chassis and server rack, ensuring stable and efficient operation.
Implementation Method 1
a roller is rotatably disposed in the slot... friction between the supporting and positioning structures and the server rack will be reduced for extracting the chassis

AI summary
A supporting and positioning structure of server chassis including a metal plate combined with the chassis. A supporting body is combined at a lateral side of the mounting plate facing the server rack and includes a base and a pair of supporting plates. The base is fixed on the mounting plate, and the pair of supporting plates are arranged in parallel and at an interval so that a slot is formed therebetween. Moreover, a roller is rotatably disposed in the slot so that the chassis of the server rack can be supported and held.
