Parallel PCB Unit for Compact Rear View Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic circuit board units for rear view devices are not space-efficient due to the need for multiple circuit boards and housings, which occupy excessive space in vehicles.
Innovation Solution
An electronic circuit board unit comprising a base plate with a driver circuit and one or more printed circuit boards disposed parallel and spaced to each other, connected via plug connections, allowing for multiple electronic consumer units to be attached, reducing the number of circuit boards required and enabling a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate circuit boards and housings are provided for each electronic consumer unit, then individual selection and functionality of each unit is achieved, but the space occupied in the rear view device increases
Solution Approach 1:
The patent combines multiple circuit boards into a single integrated circuit board unit. This circuit board unit includes a base plate with driver circuits and multiple printed circuit boards that can be selectively mounted, allowing multiple electronic consumer units to be controlled from one consolidated structure rather than requiring separate housings and circuit boards for each unit.
Solution Approach 2:
The circuit board unit is designed with universal functionality to support multiple different electronic consumer units. The base plate contains driver circuits that can interface with various types of consumer units (lights, cameras, sensors), and the printed circuit boards can be configured to support different functions, making the single unit adaptable to multiple applications.
2Reliability
If multiple circuit boards with driver circuits are provided for each electronic consumer unit, then functional independence is achieved, but the device complexity and number of components increase
Solution Approach 1:
The patent merges multiple circuit boards into one integrated circuit board unit that maintains functional independence for each electronic consumer unit. The base plate contains shared driver circuits that can independently control different consumer units, while printed circuit boards provide dedicated connection paths, reducing the total number of components while preserving functional separation.
Solution Approach 2:
The circuit board unit is segmented into a base plate with driver circuits and multiple detachable printed circuit boards. This segmentation allows the system to maintain functional independence for each consumer unit while consolidating the overall structure. Each printed circuit board can be independently mounted or removed, preserving modularity without requiring separate housings.

AI summary
An electronic circuit board unit for an electronic module installed in a vehicle rear view device. The electronic circuit board unit has a base plate, at least one printed circuit board, and at least one plug connection for an electronic and physical connection between the printed circuit board and the base plate. The electronic circuit board has at least one first receiver for mounting an electronic consumer unit of the electronic module and being attachable or attached to the base plate or to one of the at least one printed circuit board. There is at least one second connector attachable or attached to the base plate or to the at least one printed circuit board for connecting at least one further electronic consumer unit of the electronic module to the driver circuit of the base plate. This configuration provides either n printed circuit boards and n+1 of electronic consumer units, with n being an integer number of 1 and above, or a plurality of printed circuit boards is provided, with each circuit board comprising at least one first receiver and at least one second connector.
