Solution Overview
Problem
Rack-mounted servers face challenges in managing and connecting numerous network and power cables, which obstruct airflow and hinder heat dissipation due to increased computing and storage density.
Innovation Solution
An electronic device with a chassis, main board module, and electrically connecting module that includes a circuit board and connector, allowing for direct electrical connection to the rack, reducing the need for cables and enhancing airflow by using an adjustable position-limiting element and positioning elements for secure and adaptive connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the density of computing and storage units inside the cabinet is increased, then the computing and storage capability is improved, but the number of network cables and power cables increases making it difficult to manage and connect
Solution Approach 1:
The patent merges the electrical connection function directly into the rack structure by integrating electrically connecting terminals onto the rack back panel. This allows multiple computing and storage units to share common power and data connections through the rack infrastructure itself, eliminating the need for individual cables to each device and resolving the cable management complexity issue while maintaining high device density
Solution Approach 2:
The rack structure is given universal electrical connection capabilities by incorporating electrically connecting terminals that can serve multiple computing and storage units simultaneously. This multi-functional approach allows the rack to provide both mechanical support and electrical connectivity, reducing the overall system complexity and improving manageability
2Productivity
If the number of network cables and power cables is increased to support higher density units, then the computing and storage capability is improved, but air flow is blocked making heat dissipation a problem
Solution Approach 1:
By merging electrical connections into the rack structure rather than using individual cables, the patent eliminates cable clutter that blocks air flow. The integrated electrical connecting terminals provide necessary power and data connections without requiring numerous cables that would obstruct the air flow paths needed for effective heat dissipation in high-density computing environments
3Reliability
If cables are piled up in the rear of cabinets to connect all working units, then the electrical connection is achieved, but the air flow is blocked and heat dissipation is hindered
Solution Approach 1:
The patent extracts the electrical connection function from the cable system and relocates it to the rack structure itself through integrated electrically connecting terminals. This separation eliminates the harmful effect of cables blocking air flow while preserving the essential electrical connection function, thereby improving heat dissipation without sacrificing connection reliability

AI summary
An electronic device includes a chassis, a main board module and an electrically connecting module. The chassis is slidably disposed in a rack. The rack has an electrically connecting terminal. The main board module is disposed in the chassis. The electrically connecting module includes a circuit board and a first connector. The circuit board has a first connecting end corresponding to the main board module and a second connecting end corresponding to the rack. The first connecting end is electrically connected to the main board module. The first connector is disposed on the circuit board and electrically connected to the second connecting end. When the chassis is in the rack, the first connector is electrically connected to the rack. When the chassis is pulled out from the rack, the first connector is moved with the chassis such that the electrical connection between the first connector and the rack is terminated.
