Solution Overview
Problem
Existing electrical contacting methods, such as cabling, struggle to efficiently connect small and densely packed electrical components, especially when additional properties like acoustic damping, controllable vibration modes, or specific thermal conductive properties are required, which standard connection technologies cannot effectively provide.
Innovation Solution
A contacting device with a plurality of electrical conductors extending from one side to another, forming first and second electrical contact surfaces with different densities per unit area, allowing for improved electrical contact and integration with conventional connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard cabling and connection technologies are used, then electrical contact can be established, but the ability to accommodate additional properties such as acoustic damping, controllable vibration modes, or specific thermal conductive properties is lost
Solution Approach 1:
The contacting device integrates multiple functions into a single connection structure. The contacting element not only provides electrical contact but also serves as a structural component that can provide acoustic damping, vibration control, and thermal conduction pathways. This multi-functionality resolves the contradiction by eliminating the need for separate components for each function, thereby reducing overall device complexity while maintaining adaptability.
Solution Approach 2:
The contacting element is designed as a composite structure with different material properties in different regions or layers. This allows the same component to provide electrical conductivity, acoustic damping, vibration control, and thermal conduction simultaneously. The composite material approach enables the contacting device to accommodate multiple additional properties without increasing structural complexity.
2Volume of moving object
If electrical components are placed densely to reduce size, then space is saved, but the difficulty of making electrical contact increases
Solution Approach 1:
The contacting device features varying contact surface densities at different locations. The first electrical contact surface has a different number of contact surfaces per unit area compared to the second electrical contact surface. This local quality variation allows the device to accommodate dense component placement on one side while maintaining ease of connection on the other side, resolving the contradiction between compact size and ease of electrical contact.
Solution Approach 2:
The invention transitions from a two-dimensional connection interface to a three-dimensional structure with conductors extending through the volume of the contacting device. This dimensional change allows electrical contacts to be made at different depths and positions, facilitating connection to densely packed components without increasing the device's external footprint.
3Productivity
If the number of contact surfaces per unit area is increased to accommodate more components, then connectivity is improved, but the complexity of the contacting device structure increases
Solution Approach 1:
The invention merges multiple contact surfaces onto a single side of the contacting device. The first electrical contact surface contains multiple contact points that can simultaneously connect to multiple electrical components. This merging approach increases the number of electrical contacts without proportionally increasing structural complexity, as the contacts are integrated into a unified contacting element rather than requiring separate connection structures for each contact point.

AI summary
A contacting device is proposed. The contacting device comprises a plurality of electrical conductors extending from a first side of the contacting device to a second side of the contacting device different from the first side, so that a first electrical contact surface is in each case formed on the first side by a respective first end of each of the plurality of electrical conductors and a second electrical contact surface is in each case formed on the second side by a respective second end of each of the plurality of electrical conductors. A number of first electrical contact surfaces per unit area is different from a number of second electrical contact surfaces per unit area.
