PCB Power Supply Layout for High-Current Routing in Tight Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional technologies fail to address the limitations of space and costs in supporting a through-current requirement of large current on printed circuit boards (PCBs) due to limited space and high costs, leading to complex designs and inefficiencies.
Innovation Solution
A power supplying apparatus is connected directly to circuit boards, acting as both a power supplier and a lining board, reducing the need for additional lining boards and fastening screws, and utilizing a conductive mechanical part like a copper bar to meet the through-current requirement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a PCB with integrated design is used to supply power to functional circuits, then the circuit board can be compact and cost-effective, but it cannot support large current requirements due to limited space for current routing
Solution Approach 1:
The patent transitions from two-dimensional PCB trace routing to three-dimensional power supply by placing a power supplying apparatus (such as a copper bar) below the circuit board. This vertical arrangement allows large current to flow through the power supplying apparatus and connect to functional circuits via connection pieces, effectively increasing current carrying capacity without consuming additional horizontal space on the PCB.
2Reliability
If a separate lining board is added to protect circuit boards, then circuit board protection is improved, but device complexity and cost increase due to additional components and fastening requirements
Solution Approach 1:
The patent combines the protection function previously performed by a separate lining board with the power supplying apparatus. The power supplying apparatus is positioned below the circuit board to provide structural support and protection, while also serving its primary function of supplying power. This integration eliminates the need for a separate lining board and reduces the number of fastening screws required, thereby maintaining protection reliability while reducing device complexity.
3Reliability
If additional lining boards and fastening screws are arranged to protect circuit boards, then circuit board protection is improved, but costs increase
Solution Approach 1:
The patent merges the protection function with the power supplying apparatus, eliminating the need for separate lining boards and reducing fastening requirements. This integration reduces component count and assembly complexity, directly lowering manufacturing costs while maintaining the necessary protection level for circuit boards.
Solution Approach 2:
The power supplying apparatus is designed to perform multiple functions: supplying power to functional circuits and providing structural protection to circuit boards. This multi-functionality eliminates the need for dedicated protection components, reducing overall device cost while maintaining reliability.
