Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current servers are cluttered with cables, making servicing difficult due to the complexity and space requirements of internal cabling.
Innovation Solution
A connector system using a Printed Circuit Board (PCB) that travels along two axes to replace internal cabling, utilizing a rotating lever mechanism for connection and disconnection, which reduces cable clutter and simplifies servicing by distributing connection force evenly and providing a modular design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional cabling is used to connect components, then electrical connections are established, but internal server space is consumed and cable clutter increases making servicing difficult
Solution Approach 1:
The patent merges the functions of separate cables and connectors into an integrated PCB-based connection system. The PCB directly connects multiple components (storage drives, processors, memory) without requiring separate cabling, thereby eliminating cable clutter and maximizing internal server space while maintaining electrical connectivity.
Solution Approach 2:
The invention extracts and removes the extraneous cabling from the server system by replacing it with a PCB-based connection mechanism. This extraction eliminates the harmful factor of cable clutter and frees up internal space for additional components or improved airflow.
2Adaptability or versatility
If multiple separate cables are used for different connections, then all connection requirements are met, but device complexity and cable management difficulty increase
Solution Approach 1:
The PCB connection system serves multiple functions simultaneously - it provides power, data, and control signals to various components through integrated traces and connectors on a single board. This multi-functional approach replaces multiple specialized cables with one universal connection platform.
Solution Approach 2:
Multiple connection functions that previously required separate cables are merged into a single PCB structure, reducing the overall system complexity and eliminating the need for complex cable management while maintaining all necessary connection capabilities.
3Reliability
If manual cable routing and connection is performed, then connections are established, but time and effort are consumed during assembly and servicing
Solution Approach 1:
The PCB connections are pre-configured and pre-positioned on the board during manufacturing, eliminating the need for manual cable routing and connection during assembly. The connectors are already aligned and ready for engagement, significantly reducing assembly time and minimizing human error.
Solution Approach 2:
The PCB connection system is designed to self-align and self-connect when components are installed, reducing the need for manual intervention. The rigid PCB structure provides inherent alignment guidance, and the connection mechanism automatically establishes reliable electrical contacts without requiring precise manual positioning.

AI summary
A connection mechanism is provided with a circuit board that replaces internal chassis cabling to multiple electronic devices. In use, the motion of a lever of the connection mechanism drives a carrier of the circuit board in one direction to make an electrical connection at a side of the circuit board. Continued motion of the lever drives the carrier downward to make an additional electrical connections at the bottom of the circuit board.
