Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional parallel conductor tracks are used for multiple signal or power lines, then electrical contact can be established, but installation space requirement increases
Solution Approach 1:
The patent transitions from a two-dimensional parallel arrangement of conductor tracks to a three-dimensional configuration where conductor tracks are distributed on the inner circumferential surface of a cylindrical main body. This dimensional change allows multiple conductor tracks to be arranged concentrically, significantly reducing the installation space while accommodating the same number of electrical connections.
Solution Approach 2:
The patent implements a nested structure where the displacement body with sliding elements is inserted into the main body containing conductor tracks. This nested arrangement allows the contact elements to be housed within each other, minimizing the overall installation space while maintaining all necessary electrical connections.
2Ease of manufacture
If conductor tracks are arranged in one plane, then manufacturing is simple, but installation space efficiency is low
Solution Approach 1:
The patent distributes conductor tracks along the inner circumferential surface of the main body in the circumferential direction, utilizing the third dimension (circumferential angle) rather than arranging all tracks in a single plane. This spatial distribution maintains manufacturing feasibility while dramatically improving space utilization efficiency.
Solution Approach 2:
The patent employs a cylindrical geometry for the main body, replacing flat planar arrangements with curved circumferential surfaces. This curvature allows conductor tracks to be distributed around the circumference, maximizing the use of available space while maintaining structural integrity and ease of manufacture.
3Ease of operation
If contact area is exposed, then accessibility is good, but protection against contaminants and electric shock is poor
Solution Approach 1:
The patent places the sliding elements inside the main body, creating a nested configuration where the contact area is enclosed. This arrangement provides inherent protection against contaminants and electric shock while maintaining electrical accessibility through the sliding contact mechanism.
Solution Approach 2:
The patent uses the main body as a protective enclosure that shields the contact elements. The sliding elements can move within this protective shell, maintaining electrical contact while being protected from external harmful factors such as contaminants and electric shock.

AI summary
An electrical connecting device having a main body and a displacement body mounted in a linearly movable manner relative to one another in a longitudinal direction. The main body has a cavity that accommodates a longitudinal section of the displacement body or vice versa. The length of the longitudinal section accommodated in the cavity is variable by a relative longitudinal movement of the main body and the displacement body. The main body has conductor tracks extending in the longitudinal direction and insulated from one another. The displacement body has sliding elements insulated from one another and resting on and electrically contacting a contact surface of a respective one of the conductor tracks. The conductor tracks are arranged on a main body surface of the main body. The main body surface is round in a cross-sectional plane perpendicular to the longitudinal direction or is formed by a plurality of surface sections angled in relation to one another. The sliding elements project from a displacement body surface of the displacement body. The displacement body surface is round in the cross-sectional plane or is formed by a plurality of surface sections angled in relation to one another. The contact surfaces of at least two of the conductor tracks are angled in relation to one another.
