Solution Overview

Problem

Existing electrical connections between conductors lack long-term stability due to inadequate sealing and mechanical fixing, particularly in applications exposed to vibrations and environmental factors.

Innovation Solution

An electrical connection design featuring a first conductor with a contact face and a second conductor with a rim, where a reservoir space between the conductor sides is filled with a sealing material to form a sealing ring, enhancing both mechanical fixing and environmental sealing, thereby improving the stability and durability of the connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a welding layer is used to connect the first conductor and the second conductor, then electrical connection is achieved, but long-term stability of the electrical connection deteriorates

Engineering Contradiction:

Improvelong-term stability of electrical connectionVSAvoidduration of electrical connection stability

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

A sealing material is introduced as an intermediary substance between the first conductor and second conductor. This sealing material fills the reservoir space and forms a sealing ring that protects the welding layer and contact interfaces from environmental factors, thereby maintaining long-term connection stability without replacing the welding layer itself

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The sealing material forms a flexible sealing ring that adapts to the interface between conductors. This sealing ring acts as a protective barrier against dust, fluids, and gases, preventing degradation of the electrical connection over time while accommodating minor dimensional variations

Inventive Principle:

Principle #30Flexible shells and thin films

2Object-affected harmful factors

If conductors are connected without additional sealing structures, then device complexity is reduced, but resistance to environmental factors increases

Engineering Contradiction:

Improveresistance to dust, fluid, and gasVSAvoidcomplexity of connection structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The sealing material serves multiple functions simultaneously: it seals the interface against environmental factors (dust, fluid, gas), provides mechanical fixing to stabilize the connection, and protects the welding layer from corrosion. This multi-functionality achieves enhanced environmental resistance without proportionally increasing device complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The sealing ring is nested within the reservoir space formed by the rim structure of the second conductor and the first conductor. This nested arrangement integrates the sealing function into the existing connection geometry, minimizing additional complexity while maximizing protective capability

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

An electrical connection comprises a first conductor and a second conductor electrically connected to the first conductor. The first conductor has a first contact section with a first contact face laterally delimited by a first side face. The second conductor has a second contact section with a second contact face surrounded by a rim having a second side face. The second side face limits a contact space above the second contact face and the first contact face is arranged on the second contact face. A reservoir space is arranged between the first side face of the first contact face and the second side face of the rim, the reservoir space surrounds the first contact face and a sealing material is arranged in the reservoir space. The sealing material forms a sealing ring that seals an interface between the first contact face and the second contact face.
