Tool-less Server Chassis Mounting via Staggered Backing Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional blade server systems face challenges in simplifying and improving accessibility to server components due to the need for tool-based mounting and potential damage during installation, as well as issues with electromagnetic interference.
Innovation Solution
A server mounting system that uses a backing plate with tapered holes in a staggered pattern to align and couple with the server chassis, allowing for tool-free insertion and extraction of system boards, while also providing EMI resistance without traditional clips and gaskets, and incorporating a protective layer for impact resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional tool-based mounting is used, then secure attachment is achieved, but installation time and complexity increase
Solution Approach 1:
The patent replaces traditional mechanical fastening systems (screws, clips, tools) with a spring-loaded plunger mechanism that uses elastic potential energy storage and release to achieve secure attachment through simple push-button operation, eliminating the need for tools and reducing installation time
Solution Approach 2:
The mounting system is designed to be self-servicing through the spring-loaded plunger mechanism that automatically engages and disengages the mounting tab with the receptacle through push-button operation, without requiring external tools or complex assembly procedures
2Reliability
If traditional mounting methods are used, then secure attachment is achieved, but risk of damage during installation increases
Solution Approach 1:
The patent replaces forceful mechanical fastening methods with a controlled spring-loaded plunger mechanism that uses elastic deformation to gradually engage the mounting tab with the receptacle, minimizing impact forces and reducing the risk of damage during installation
Solution Approach 2:
The spring element in the plunger mechanism acts as a cushioning element that absorbs and distributes forces during engagement, preventing sudden impacts that could damage the system board or chassis components during the mounting process
3Object-affected harmful factors
If traditional EMI protection methods (clips and gaskets) are used, then electromagnetic interference resistance is achieved, but device complexity increases
Solution Approach 1:
The patent combines the EMI shielding function with the existing mounting structure by making the chassis base pan itself EMI-shielded, eliminating the need for separate EMI clips and gaskets, thereby reducing structural complexity while maintaining electromagnetic interference resistance
Solution Approach 2:
The chassis base pan is designed to serve multiple functions simultaneously: structural support, mounting surface, and EMI shielding barrier, eliminating the need for separate dedicated EMI protection components and reducing overall device complexity

AI summary
Embodiments of the present invention are directed to a mounting system. The mounting system may include a chassis comprising a base and a plurality of guide ramps and a plurality of mounting spools arranged in pairs extending from a first side of the base, wherein the pairs are unaligned with respect to one another relative to a direction along at least one length of the base. Further, the mounting system may include a backing plate coupled to the chassis via engagement of the pairs with a plurality of receptacles in the backing plate.
