Electrical Adapter With Integrated Supply Current Filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation space constraints in the electronic control system of heating devices, particularly on circuit boards, limit the integration of commercially available filters, hindering the placement of other electronic elements.
Innovation Solution
Integrating a filter device for electric supply current filtration within the electrical adapter rather than the electronic control system, allowing for spatial proximity to electrical supply lines and reducing the need for installation space in the control system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter device is mounted on the circuit board in the electronic control system, then the electric supply current can be filtered, but the installation space on the circuit board is occupied and not available for other electronic elements
Solution Approach 1:
The filter device is extracted from the electronic control system and integrated into the electrical adapter instead. This allows the filter to be positioned in the adapter's housing where sufficient space is available, while maintaining its filtering function on the electric supply current before it reaches the control system.
Solution Approach 2:
The filter device is nested within the electrical adapter's housing structure. The adapter serves as a container that houses both the filter device and the electronic control system, allowing the filter to occupy space in the adapter rather than on the limited circuit board area.
2Area of stationary object
If the filter device is integrated into the electrical adapter, then installation space in the control system is freed up, but the filter device must be positioned at an appropriate distance from the electrical supply lines
Solution Approach 1:
The filter device is positioned in a different spatial dimension within the adapter's housing, utilizing the three-dimensional space available in the adapter rather than the two-dimensional circuit board surface. This allows the filter to be close to the electrical supply lines while not competing for the same installation space.
3Reliability
If commercially available filters are used as complete units, then the filtering function is provided, but the entire filter unit occupies valuable installation space on the circuit board
Solution Approach 1:
The electrical adapter is segmented into functional zones, with the filter device occupying a specific area in the adapter housing separate from the electronic control system. This segmentation allows the filter to be positioned optimally for its function without encroaching on circuit board space.

AI summary
An electrical adapter for electrically connecting a control unit of a heating device to an electric energy source and to an electrical signal source. The adapter may include a support, an electrical signal line, a first electrical supply line, a second electrical supply line, and a filter device. The signal line and the supply lines may be embedded in a plastic material of the support. Ends of the signal line may merge into a signal input connection and into a signal output connection. Ends of the supply lines may merge into a first and second electrical supply input connection and into a first and second electrical supply output connection. The filter device may be configured to filter an electric supply current conducted via the supply lines. The filter device may include a first and second electrical filter connection via which the filter device is electrically connected to the supply lines.
