Power Distribution Bus Bar for Surface Mount Connectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current power delivery systems for add-in cards are limited by size constraints, leading to increased chassis height and inefficiencies in power distribution, as they rely on individual cables that impede airflow and require more space, making it difficult to fit multiple add-in cards in compact chassis configurations.
Innovation Solution
A power distribution bus bar system that uses a circuit board with surface-mounted add-in card connectors and power connectors, allowing for efficient power distribution to multiple add-in cards without the need for individual cables, thereby reducing height requirements and enhancing airflow and space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If individual power cables are used to connect add-in cards, then power delivery is achieved, but chassis height increases and airflow is impeded
Solution Approach 1:
The invention extracts the power delivery function from separate physical cables and integrates it directly into the circuit board through embedded power traces and power supply connectors. This eliminates the need for external power cables connecting to add-in cards, thereby reducing chassis height requirements while maintaining power delivery capability.
Solution Approach 2:
The invention merges the power delivery function with the data connection function by integrating power supply connectors and power traces directly into the circuit board that also carries the add-in card connectors. This combination eliminates separate power cables and reduces overall system height.
2Power
If individual power cables are used for each add-in card, then power distribution is achieved, but space efficiency decreases and airflow is blocked
Solution Approach 1:
The invention combines multiple power delivery functions into a single integrated circuit board structure. The circuit board contains embedded power traces that distribute power to multiple add-in card connectors simultaneously, eliminating the need for separate power cables for each card and improving space efficiency.
Solution Approach 2:
The circuit board serves multiple functions: it provides data connection through add-in card connectors, distributes power through embedded power traces, and houses power supply connectors. This multi-functionality eliminates the need for separate power cables and optimizes chassis volume utilization.
3Power
If power cables are used to connect add-in cards, then power supply is achieved, but chassis height requirement increases
Solution Approach 1:
The invention extracts the power supply function from external cables and embeds it directly into the circuit board through integrated power traces and connectors. This eliminates the height requirement imposed by external power cables while maintaining the power supply function.
4Power
If individual cables are used for each add-in card, then power delivery to each card is achieved, but device complexity increases
Solution Approach 1:
The invention extracts the power delivery function from separate cables and integrates it into the circuit board, eliminating cable management complexity while maintaining individual power delivery capability to each add-in card through embedded traces.
Solution Approach 2:
The invention merges the power delivery infrastructure into the circuit board itself, combining multiple power traces and connectors into a single integrated structure. This eliminates the complexity of managing multiple separate power cables while maintaining the ability to power multiple add-in cards independently.
