Solution Overview
Problem
Current server node ID address recognition systems face issues with reliability due to connector wear and foreign matter interference, difficulty in assembly, limited universality, and high implementation complexity, especially when dealing with different backplane heights and heavy server nodes.
Innovation Solution
A non-contact optical medium is used for communication between a first recognition module in the cabinet and a second recognition module in the server, eliminating the need for physical contact and reducing electromagnetic interference, with light exit and entrance holes configured to convert optical signals into digital node ID addresses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If connector contacts are used for ID address recognition, then the server node can obtain its position in the cabinet, but the reliability deteriorates due to contact abrasion and foreign matter interference after multiple plugging and unplugging operations
Solution Approach 1:
The patent replaces the mechanical contact-based ID recognition system with an optical communication system. A light source in the server node emits light that passes through optical channels (holes) in the backplane and cabinet structure to a light receiver in the cabinet. The pattern of open/closed optical channels encodes the server node's position information, eliminating mechanical contacts and their associated wear and reliability issues.
Solution Approach 2:
The patent introduces light as an intermediary medium for ID address recognition. Instead of direct electrical contact between connectors, the system uses light transmission through optical channels as the intermediary to convey position information, thereby avoiding the harmful effects of mechanical contact including abrasion, oxidation, and foreign matter interference.
2Ease of manufacture
If blind plugging is used for assembling server nodes into the cabinet, then the assembly process is simple, but the ease of operation deteriorates due to connector damage from misalignment and impact
Solution Approach 1:
The patent moves the ID recognition function from the electrical contact dimension to the optical dimension. By using optical channels (holes) that are spatially arranged to encode position information, the system provides inherent alignment guidance during assembly without requiring high-precision mechanical guide pins, thus improving ease of operation while maintaining assembly simplicity.
3Adaptability or versatility
If multiple backplanes with different heights are combined to support different numbers of nodes, then the adaptability improves, but the device complexity increases due to the need for multiple backplane configurations
Solution Approach 1:
The patent creates a universal ID recognition system where the same optical channel structure and recognition modules can serve multiple backplane configurations. The optical channels are arranged in a standardized pattern that can encode positions across different backplane heights and cabinet configurations, eliminating the need for multiple specialized backplane designs while maintaining adaptability.
