Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If wireless communication is used in data center, then cable quantity is reduced and ventilation is improved, but electromagnetic radiation affects electronic device service life and signal transmission quality
Solution Approach 1:
The patent changes the signal transmission direction from horizontal to vertical by arranging antennas and function nodes in vertical layers. The first antenna group transmits signals vertically to the second antenna group, which then transmits to function nodes. This dimensional change allows electromagnetic waves to propagate away from sensitive electronic components, reducing interference while maintaining wireless communication benefits.
Solution Approach 2:
The patent introduces a shield layer as an intermediary between the antenna groups and function nodes. This shield layer acts as a barrier that blocks or absorbs electromagnetic radiation, preventing direct interference with electronic devices while allowing the wireless communication system to operate effectively.
2Device complexity
If horizontal radio signal transmission is used, then communication is simplified, but electromagnetic radiation reduces electronic device service life and transmission quality
Solution Approach 1:
The patent introduces vertical signal transmission as an intermediate step between antenna groups and function nodes. This vertical transmission path directs electromagnetic waves away from the horizontal plane where sensitive electronics reside, reducing interference and improving signal quality while adding structured organization to the communication system.
Solution Approach 2:
The shield layer serves as a protective intermediary that filters harmful electromagnetic radiation from reaching function nodes and electronic devices, thereby improving transmission quality and device reliability without significantly complicating the overall communication architecture.
3Ease of repair
If wireless communication is implemented, then cable-related maintenance issues are resolved, but electromagnetic interference becomes a new maintenance challenge
Solution Approach 1:
The shield layer acts as a protective intermediary that mitigates electromagnetic radiation effects on electronic devices. This shield reduces the harmful impacts of wireless communication, making the system more reliable and easier to maintain by preventing radiation-induced failures in sensitive components.
Solution Approach 2:
The patent converts the potentially harmful electromagnetic radiation into a controlled transmission medium by using vertical propagation paths and shield layers. The radiation that would otherwise interfere with electronics is redirected vertically and filtered, transforming a harmful effect into a manageable aspect of the communication system.

AI summary
A cabinet server and a data center based on the cabinet server are disclosed. The cabinet server includes at least two function nodes, multiple intra-cabinet antennas, and multiple inter-cabinet antennas. The function nodes are vertically arranged, to form a server core; and the intra-cabinet antennas are vertically arranged, disposed at a side of the server core, and electrically connected to corresponding function nodes, and adjacent intra-cabinet antennas are wirelessly connected. When a radio signal is transmitted within the cabinet server, a transmission path is formed of the vertically arranged intra-cabinet antennas. Because the intra-cabinet antennas are disposed at the side of the server core, electromagnetic radiation generated by the radio signal in a transmission process has a relatively small effect on the function nodes, thereby reducing the effect of the electromagnetic radiation on various electronic devices in the function nodes, improving service lives of the electronic devices, and improving transmission quality of the radio signal.
