Vertically Mounted Power Control Assembly for Aircraft Circuit Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional power control devices on aircraft circuit boards are inefficient in utilizing space due to their thin, horizontal configuration, leading to wasted volume and limited circuit board density, as they occupy a large area without much height, necessitating larger boards or closer spacing with height limitations.
Innovation Solution
A power control system featuring vertically mounted distribution bars with three sections, where the first section connects to a bus bar, the second section carries power and includes power switches, and the third section attaches to the circuit board, allowing for selective power distribution and improved circuit density by utilizing otherwise wasted volume.

Engineering Contradiction Analysis
1Area of stationary object
If power control devices are mounted horizontally on circuit boards, then the mounting area is maximized, but the volume utilization is poor and circuit board density is limited
Solution Approach 1:
The patent transitions from traditional horizontal mounting to vertical mounting of power control devices. The distribution bar is positioned vertically relative to the circuit board, allowing power switches to be mounted on the vertical surface of the distribution bar rather than on the horizontal circuit board surface. This dimensional change enables utilization of vertical space that was previously wasted, thereby improving volume utilization while maintaining circuit board area efficiency.
2Power
If more circuit boards are used to increase power distribution capacity, then the power distribution capability is improved, but the system volume and complexity increase
Solution Approach 1:
The patent combines multiple functions into a single vertical distribution bar structure. The distribution bar serves as both the power distribution conductor and the mounting substrate for power switches, replacing what would traditionally require separate circuit boards and mounting structures. This merging allows multiple power switches to be mounted on one vertical bar, increasing power distribution capacity within the same volume that would have been occupied by multiple horizontal circuit boards.
3Volume of stationary object
If circuit boards are placed closer together to reduce volume, then the system volume is reduced, but the spacing is limited by connector height
Solution Approach 1:
By mounting power switches vertically on the distribution bar rather than horizontally on circuit boards, the patent eliminates the need for additional horizontal spacing between circuit boards. The vertical mounting configuration allows circuit boards to be positioned closer together since the power switches no longer extend horizontally from the board surface, thereby reducing overall system volume while maintaining ease of assembly and connection.

AI summary
A power control system includes a circuit board (14), a bus bar (16), and a distribution bar (12a). The bus bar (16) is connected to the circuit board (14) and configured to receive input power from an external power source. The distribution bar (12a) is connected to receive the input power from the bus bar (16). The distribution bar includes a first section (34) connectable to the bus bar to receive the input power, a second section (36) configured to carry the input power from the first section, a third section (38) connectable to the circuit board (14), and a power switch (24) connected to the second section (36) and configured to selectively distribute the input power as output power to at least one load. The first section (34) and the third section (38) extend away from the second section.
