Server Casing Plate Connecting Structure for Space Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server casing designs that rivet side boards together occupy internal space, reducing the capacity for disk drives and causing space inefficiency.
Innovation Solution
A plate connecting structure with a first side board and a second side board, featuring opening structures with specific peripheries and limiting surfaces, allowing for riveting without additional space occupation, enabling efficient use of internal space by aligning and engaging riveting structures with opening structures to securely connect the boards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional plate connecting design rivets board edges of side boards together, then the two side boards are fixed securely, but the stacked board edges occupy partial internal containing space, reducing the allowed amount of disk drives and causing space waste
Solution Approach 1:
The patent transitions from a conventional edge-stacking riveting approach to a through-hole riveting approach where riveting structures pass completely through the side boards. This dimensional change allows the riveting components to be located in the thickness direction of the boards rather than occupying the internal containing space, thereby resolving the space occupation problem while maintaining secure fixation.
Solution Approach 2:
The patent extracts the riveting structures from the internal containing space and positions them on the outer surfaces of the side boards. By using through-holes that extend through the entire thickness of the side boards, the riveting components are taken out from the problematic stacked board edge configuration and repositioned to engage with opening structures on the outer surfaces, eliminating space occupation while preserving fixing strength.
2Stability of the object's composition
If riveting structures are designed to engage with opening structures through limiting surfaces, then the connection between first side board and second side board is secured, but the structure becomes more complex with multiple peripheries and surfaces
Solution Approach 1:
The patent segments the connection function into distinct components: opening structures with outer and inner peripheries in the first side board, and corresponding riveting structures with matching peripheries in the second side board. Each component has specific limiting surfaces that work together to provide stable connection. This segmentation allows for modular design and assembly while achieving the desired connection stability.

AI summary
A server casing includes a frame having first and second plates and a plate connecting structure including first and second side boards extending from the first and second plates respectively and having first and second opening structures and first and second riveting structures respectively. A first outer periphery of the first opening structure is larger than a first inner periphery, and a first limiting surface extends therebetween. A second outer periphery of the second opening structure is less than a second inner periphery, and a second limiting surface extends therebetween. The first and second riveting structures have third and fourth limiting surfaces respectively. When the second riveting structure is engaged with the second opening structure and the second and fourth limiting surfaces abuts against each other, the first riveting structure is pressed to engage with the first opening structure and the first and third limiting surfaces abuts against each other.
