Dummy Chassis for Server Rack Socket Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current server rack configurations pose risks of accidental electrical contact and dust/foreign object intrusion when power sockets are exposed without server units, disrupting airflow and maintenance safety.
Innovation Solution
A dummy chassis with a modular design featuring interconnected frame bars and a connection member, allowing tool-free assembly, foolproof engagement mechanisms, and compact storage, which can be quickly inserted into server racks to cover power sockets and maintain airflow paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If server units are removed from rackmount chassis for maintenance or replacement, then ease of operation is improved, but power sockets become exposed causing safety hazards and dust intrusion
Solution Approach 1:
The patent uses a dummy chassis that replicates the appearance and dimensions of a real server unit without containing actual electronic components. This copy blocks power sockets and maintains rack structure while enabling safe removal of real server units for maintenance, thus improving accessibility while preventing electrical contact and dust intrusion risks
2Adaptability or versatility
If configuration space is left empty for server unit replacement, then adaptability is improved, but airflow paths are disrupted and foreign objects may intrude
Solution Approach 1:
The dummy chassis replicates the form factor of a server unit to maintain proper airflow paths and block foreign object intrusion, while allowing real server units to be easily replaced in other positions, thus maintaining adaptability without generating harmful effects
Solution Approach 2:
The dummy chassis is designed as a simple, inexpensive structure without complex electronic components, serving as a temporary placeholder to maintain rack integrity and airflow during server unit replacement operations
3Ease of manufacture
If dummy chassis is designed with modular frame bars for easy assembly, then ease of manufacture is improved, but device complexity increases
Solution Approach 1:
The dummy chassis is divided into modular frame bars that can be independently manufactured and then assembled together using simple connection mechanisms, making the manufacturing process easier while the modular design itself adds minimal complexity through standardized interfaces
4Volume of moving object
If connection member width is reduced for compact storage, then volume of moving object is improved, but engagement reliability may be compromised
Solution Approach 1:
The frame bars are designed to nest within each other when not in use, with the connection member featuring a reduced width that allows it to be stored compactly within the rack structure, while maintaining sufficient engagement surface area when deployed to ensure reliable connections

AI summary
A dummy chassis includes a first frame bar, a second frame bar and a connection member. The first frame bar has a first long side and a first engaging portion. The second frame bar has a second long side and a second engaging portion. The connection member has two end portions which are located oppositely. The first end portion has a third engaging portion. The second end portion has a fourth engaging portion. A width of the connection member is less than a length of the first frame bar and a length of the second frame bar.
