Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The industry lacks a mature solution for effective EMC shielding design in centralized power supply systems using copper bars within cabinet-level servers, particularly in open rack applications, where integrating shielding materials and achieving overlap among components is challenging.
Innovation Solution
A centralized power supply shielding structure that integrates a power supply copper bar with plug-in frames and an inner container shielding can, where the copper bar's plugs are inserted through holes in the shielding unit to supply power while shielding the frames from the copper bar, utilizing a simple structural design suitable for open rack environments.

Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional shielding design is used for centralized power supply copper bar, then shielding effectiveness can be achieved, but the design becomes complicated and difficult to implement
Solution Approach 1:
The patent merges the shielding can with the rack structure to form an integrated shielding unit. The shielding can is combined with the plug-in frame, eliminating the need for separate shielding components and complex overlap joining among multiple separate components. This integration maintains shielding effectiveness while significantly simplifying the overall structure and implementation.
Solution Approach 2:
The shielding can serves multiple functions: it provides EMC shielding for the copper bar, acts as a structural support component, and integrates with the rack system. This multi-functionality reduces the number of separate components needed and simplifies the overall shielding design while maintaining effectiveness.
2Reliability
If shielding material is added to achieve effective shielding, then EMC compatibility improves, but the structural design becomes more complex
Solution Approach 1:
The shielding material is integrated into the rack and frame structures rather than being added as separate components. The shielding can is formed as part of the overall structural assembly, making the shielding function inherent to the structure itself. This approach maintains EMC compatibility while preserving ease of manufacture and structural simplicity.
