Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electrical contacting methods are used for cable harnesses in treatment systems, then reliable electrical connection can be achieved, but the complexity of the contacting system increases and ease of operation deteriorates
Solution Approach 1:
The contacting system is segmented into a connection module with integrated contact pins and a cable harness with conductor elements. This segmentation allows each component to be optimized independently while simplifying the overall assembly process and improving ease of operation without compromising reliability.
Solution Approach 2:
The contact pins serve as intermediaries between the connection module and the cable harness conductor elements. These pins provide a standardized interface that simplifies the contacting process while ensuring reliable electrical connection through controlled contact geometry and material properties.
2Ease of operation
If the cable harness is made connectable with simple means for untrained users, then ease of operation improves, but the reliability of the electrical connection may deteriorate
Solution Approach 1:
The contact pins are pre-positioned and pre-configured in the connection module with precise spacing and orientation. This preliminary action ensures that when the cable harness is simply plugged in, reliable electrical connection is automatically achieved without requiring user expertise, thus maintaining both ease of operation and reliability.
Solution Approach 2:
The contacting system is designed to be self-aligning and self-securing. The cable harness automatically positions itself relative to the contact pins during insertion, and the system self-verifies the connection through the mechanical and electrical interface, eliminating the need for user adjustment while ensuring reliable connection.
3Device complexity
If contact pins are positioned close together for compact design, then device complexity decreases, but the mechanical fixation of the cable section deteriorates
Solution Approach 1:
The contacting function and the mechanical fixation function are merged into a single integrated connection module. The contact pins simultaneously provide electrical connection and mechanical anchoring of the cable harness, eliminating the need for separate fixation elements and achieving compact design without compromising reliability.
Solution Approach 2:
The contact pins are designed with multi-functionality, serving both as electrical conductors and as mechanical fixation elements. This universal design allows the system to achieve compactness while maintaining reliable mechanical fixation through the dual-purpose nature of the pins.

AI summary
A contacting system (20) for electrically contacting electric conductor elements (14) imbedded into an insulating jacket (10) of a cable strand (4a) is to allow the cable strand (4a) to be electrically contacted so as to meet increased reliability requirements in a particularly simple and inexpensive manner. According to the invention, this is achieved by a connection module (22), in the outer housing (25) of which a sub-section of the cable strand (4a) can be fixed, and by a number of contact pins (36), which pass transversely through the outer housing (25) when viewed laterally relative to the longitudinal direction of the cable strand (4a).
