Solution Overview

Problem

Workshops face the challenge of needing multiple adapters for different electric vehicle charging sockets due to varying plug types, which complicates safety-critical measurements, especially when dealing with high-voltage systems, and existing CCS adapters often lack compatibility with Type 2 sockets.

Innovation Solution

A measuring adapter with two movable charging plugs of different types, allowing a single adapter to fit various charging sockets, and includes movable contacts connected to measuring contacts for safe and versatile measurements, optionally with a fuse for protection against overvoltage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple adapters are used for different charging socket types, then compatibility with various electric vehicle charging sockets is improved, but device complexity and operational convenience deteriorate due to the need to manage and switch between multiple adapters

Engineering Contradiction:
Improvecompatibility with various charging socket typesVSAvoidnumber of adapters required
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple charging plug types (Type 1 and Type 2) into a single adapter body, allowing the adapter to interface with different charging sockets without requiring separate adapters for each type. This merging approach directly reduces the total number of adapters needed in the workshop.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The adapter is designed with universal functionality to work with multiple charging socket types through its movable second charging plug mechanism. The adapter can adapt between Type 1 and Type 2 sockets, providing multi-functionality that eliminates the need for type-specific adapters.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Device complexity

If existing CCS adapters are used without Type 2 socket contacts, then the adapter design is simplified, but measurement capability on Type 2 sockets deteriorates

Engineering Contradiction:
Improveadapter designVSAvoidmeasurement capability on Type 2 socket
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The second charging plug is designed to be movable between a passive position (where it does not interfere with Type 1 connections) and an active measuring position (where it provides contact with Type 2 socket contacts). This dynamic positioning enables the adapter to provide Type 2 measurement capability only when needed, maintaining design simplicity while expanding functionality.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The movable second charging plug acts as an intermediary element that bridges the gap between Type 1 and Type 2 socket interfaces. When activated, it provides the necessary contact points for Type 2 measurements without requiring a completely separate adapter design.

Inventive Principle:
Principle #24Intermediary (Mediator)
