Rack Frame Corner Assembly for Easy Disassembly and Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rack frame assemblies for servers are inconvenient to disassemble after the frames and support poles are welded together, limiting flexibility and maintenance access.
Innovation Solution
A rack frame assembly design featuring linking members and linking posts with specific hole configurations and cutouts allows for secure assembly and disassembly, utilizing a linking member with an L-shaped insert portion and a linking post with different diameter portions to align and connect the frame poles and support poles, facilitated by a bent piece for securing the assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the frame poles and support poles are welded together, then the structural strength and stability are improved, but the ease of disassembly and reconfiguration deteriorates
Solution Approach 1:
The corner connection is divided into separable components: a corner assembly with corner bodies and corner plates, and support poles with corresponding connection structures. This segmentation allows the connection to be assembled and disassembled while maintaining structural strength through the bolted connection between corner plates and support poles.
Solution Approach 2:
Corner plates serve as intermediary elements between the frame poles and support poles. These corner plates with through holes and bolt holes enable the connection without requiring direct welding, thus maintaining ease of disassembly while ensuring structural integrity through the mediating corner plate component.
2Manufacturing precision
If welding is used to assemble the rack frame assembly, then the manufacturing precision and structural integrity are improved, but the ease of repair and maintenance deteriorates
Solution Approach 1:
The connection structure is segmented into removable parts (corner bodies, corner plates, support poles) that can be independently accessed and replaced. This segmentation enables maintenance personnel to repair or replace individual components without affecting the entire structure, significantly improving ease of repair compared to welded assemblies.
Solution Approach 2:
The corner plates and support poles are designed to be extractable from the corner bodies through the through holes and bolt connections. This extraction capability allows damaged or worn components to be removed and replaced independently, facilitating maintenance without requiring complex welding operations.
3Stability of the object's composition
If the rack frame assembly is designed for secure connection, then the stability is improved, but the adaptability for reconfiguration deteriorates
Solution Approach 1:
The connection system transitions from a static welded joint to a dynamic bolted connection that can be assembled, disassembled, and reconfigured. The corner plates with through holes and bolt holes provide a stable connection when assembled, while allowing easy reconfiguration when needed, thus achieving both stability and adaptability.
Solution Approach 2:
The corner bodies and corner plates are designed with universal connection features (through holes, bolt holes, L-shaped insert portions) that can accommodate different support pole configurations. This multi-functionality enables the same corner assembly to support various rack configurations, improving adaptability while maintaining stable connections.

AI summary
A rack frame assembly includes a first frame pole, a second frame pole, a linking member, linking post, and a support pole. A first frame pole includes a first support wall and a first through hole. The second frame pole includes a second support wall. The second frame pole is assembled with the first frame pole with the first support wall and the second support wall is located on the same plane. The linking member is located on the first support wall and the second support wall. The linking member includes a second through hole in alignment with the first through hole, and an insert portion. The linking post is located in the first through hole and the second through hole to secure the linking member to the first frame pole. The support pole includes an insert hole with the insert portion located therein.
