Die-Cast Server Rear Wall for Multi-Card Riser Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing server type information handling systems face challenges in providing a single chassis design that can support a variety of card configurations, including PCIe, OCP, and DC-SCM cards, and require a rear wall structure with sufficient flexibility and strength to accommodate these configurations.
Innovation Solution
A rear wall system with integrated riser attachment features, a die-cast construction, and a gripping area that enhances strength, facilitates riser installation, and serves as a component handle, spanning across a large portion of the server chassis to support multiple card configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional rear wall structure is used, then the server chassis can maintain simple construction, but it cannot provide sufficient strength and flexibility to support multiple card configurations
Solution Approach 1:
The patent merges the rear wall structure with integrated riser attachment features and a gripping area into a single unified component. This integration provides the necessary strength and flexibility to support multiple card configurations (PCIe, OCP, DC-SCM) while avoiding the need for separate structural elements, thus resolving the contradiction between strength and complexity.
Solution Approach 2:
The rear wall structure is designed with universal attachment features that can accommodate various card types and configurations. The integrated riser attachment features and gripping area serve multiple functions: structural support, card installation facilitation, and component handling, thereby achieving multi-functionality that resolves the contradiction between strength requirements and construction simplicity.
2Ease of operation
If a rigid rear wall structure is used, then manufacturing is simpler, but riser installation becomes difficult and the structure lacks flexibility for diverse card configurations
Solution Approach 1:
The rear wall structure incorporates pre-integrated riser attachment features during manufacturing. These pre-positioned attachment points facilitate easy riser installation by eliminating the need for complex assembly operations, thereby improving ease of operation while maintaining manufacturing simplicity through the integrated design.
Solution Approach 2:
The rear wall structure incorporates flexible elements that allow for dynamic adjustment and easy installation of risers. The integrated design includes features that enable the structure to adapt during installation while maintaining structural integrity, resolving the contradiction between ease of installation and manufacturing simplicity.
3Strength
If the rear wall spans the entire chassis, then structural strength is maximized, but the gripping area and attachment features become more complex
Solution Approach 1:
The rear wall structure implements local quality by concentrating attachment features and the gripping area at specific strategic locations rather than distributing complexity uniformly. This allows the rear wall to span the chassis for maximum strength while keeping attachment feature complexity localized to specific zones, resolving the contradiction between overall strength and feature complexity.
