Motor Vehicle Lock Control Layout With Stacked Energy Store
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic control devices for motor vehicle locks require a wide base area due to the flat arrangement of electronic components and energy stores, limiting their installation in spaces with limited space availability.
Innovation Solution
The electronic control device is designed with a two-plane structure where electronic components are arranged in a first plane and energy stores, such as supercapacitors, are offset and arranged in a second plane above the components, reducing the base area and allowing for a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If electronic components and energy stores are arranged flatly next to each other on the circuit board, then the design is very flat and space-saving in terms of height, but the base area becomes wide and requires sufficient installation space
Solution Approach 1:
The patent transitions from a two-dimensional flat arrangement to a three-dimensional stacked arrangement by positioning energy stores in a second plane above the circuit board. This vertical stacking approach reduces the base area footprint while maintaining compact dimensions, allowing installation in spaces with limited horizontal area availability.
2Area of stationary object
If the base area is reduced for compact installation, then installation space requirements are minimized, but the arrangement of electronic components and energy stores becomes more complex
Solution Approach 1:
The patent divides the electronic control device into distinct planes: a first plane containing the circuit board with electronic components, and a second plane containing energy stores positioned above. This segmentation into separate layers simplifies the arrangement within each plane while achieving compact base area, as components don't need to share the same two-dimensional space.
