Power Pack PCB Layout for Flexible Connector Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power pack assemblies for vehicle steering systems lack design flexibility due to fixed connector orientations, limiting layout options and adaptability to various vehicle configurations.
Innovation Solution
A power pack assembly design featuring a housing with uncovered radial segments for circuit board extensions, allowing adjustable connector locations and orientations to accommodate different system requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the PCB and electrical connectors use a fixed single orientation architecture, then the manufacturing and assembly process is simplified, but the design layout flexibility and adaptability to various vehicle configurations is reduced
Solution Approach 1:
The circuit board is segmented into a main portion (covered by housing) and multiple extended segments (uncovered by housing), allowing connectors to be positioned at different locations and orientations while maintaining a standardized base architecture for manufacturing
Solution Approach 2:
The circuit board extends radially outward from the longitudinal axis in multiple directions, adding spatial dimensionality to connector placement. This allows connectors to access different sides and positions of the power pack assembly without changing the fundamental single-board architecture, thus maintaining manufacturing simplicity while achieving design flexibility
2Adaptability or versatility
If the circuit board extends radially outward from the housing, then the connector location flexibility is improved, but the device complexity increases
Solution Approach 1:
The radial extended segments serve multiple functions: they provide mechanical support for connectors, enable various connector orientations, and maintain electrical continuity with the main PCB. This multi-functionality reduces the need for additional components or complex routing, thereby limiting the increase in device complexity despite improved flexibility

AI summary
A power pack assembly includes a housing extending axially about a longitudinal axis. The power pack assembly also includes a circuit board having a board main portion covered by the housing and having a first board extended segment extending radially away from the longitudinal axis and out of the housing and uncovered by the housing. The power pack assembly further includes at least one logic connector disposed on the first board extended segment of the circuit board.
