Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Open type hardware server designs face challenges in passing electromagnetic interference (EMI), electromagnetic compatibility (EMC), and safety tests, which conventional server package structures can handle but not the open designs.
Innovation Solution
A drawer with a moveable or rotatable bezel door structure that serves as an electrostatic shield, allowing access to the node while maintaining electrostatic integrity, configured for use in open type hardware servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an open type hardware server design is used, then accessibility and structural simplicity are improved, but electromagnetic interference (EMI), electromagnetic compatibility (EMC), and safety performance deteriorate
Solution Approach 1:
The bezel is divided into a fixed portion and a movable door structure, allowing the server to maintain an open configuration for accessibility while providing a shielded environment when closed for EMI/EMC protection. This segmentation enables the system to switch between open and closed states as needed.
Solution Approach 2:
The door structure is designed to be movable rather than fixed, allowing dynamic transition between open and closed positions. This enables the server to adapt its shielding characteristics based on operational requirements, providing both accessibility and EMI protection at different times.
2Object-affected harmful factors
If a conventional server package structure is used, then electromagnetic interference (EMI), electromagnetic compatibility (EMC), and safety performance are improved, but accessibility and structural simplicity deteriorate
Solution Approach 1:
The bezel with movable door structure serves multiple functions: it provides structural support, enables accessibility when open, and provides EMI/EMC shielding when closed. This multi-functionality replaces the need for separate shielding structures, reducing overall device complexity.
Solution Approach 2:
The EMI shielding function is merged with the access door structure, combining two previously separate functions (shielding and access) into a single integrated component. This reduces the number of separate parts and simplifies the overall structure.
3Reliability
If a movable door structure is added to provide electrostatic shielding, then electromagnetic compatibility (EMC) performance is improved, but device complexity increases
Solution Approach 1:
The door structure serves dual purposes: providing physical access when open and electrostatic shielding when closed. By making the access door itself the shielding structure, the patent avoids adding separate shielding components, thereby improving EMC without proportionally increasing complexity.
Solution Approach 2:
The bezel structure is discarded as a simple decorative element and recovered as a functional electrostatic shield through the addition of the movable door mechanism. This transforms a previously non-essential component into a multi-functional element that provides both access and shielding.
