Solution Overview

Problem

The existing wall charging stations require specialist installation and configuration, leading to high costs and safety risks when used with improper extension cables, and the infrastructure is not adaptable for non-specialist installation, posing challenges for widespread adoption and flexibility in charging infrastructure expansion.

Innovation Solution

A wall charging station design featuring a plug-in connection with a pre-installed standard-compliant CEE wall socket and an adapter device, along with a wall-mountable mounting device that allows for precise alignment and fixing, enabling non-specialist installation while maintaining safety standards, and incorporating data communication interfaces via wireless systems to decouple electrical and IT infrastructure setup.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a wall-mounted charging station is installed by a specialist company, then safety and compliance with standards are ensured, but installation costs and complexity increase

Engineering Contradiction:
Improvesafety complianceVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The charging station system is divided into two separate parts: a wall socket with integrated differential voltage protection that can be installed by specialists, and a charging unit that can be independently mounted and configured by end users. This segmentation allows the safety-critical components to be pre-installed and certified, while the user-facing components remain simple to deploy

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wall socket with differential voltage protection is pre-installed and pre-configured by specialist companies during building infrastructure setup. This preliminary action ensures safety compliance is established beforehand, allowing end users to later simply mount the charging unit without needing to perform complex electrical installations or safety configurations

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If electrical infrastructure and charging stations are installed simultaneously, then coordination is simplified, but unnecessary investment costs occur as not all users need charging stations immediately

Engineering Contradiction:
Improveinstallation coordinationVSAvoidinvestment cost
Core Design Contradiction:
Ease of manufactureVSQuantity of substance

Solution Approach 1:

The system separates the electrical infrastructure (wall socket with protection) from the charging station unit, allowing the infrastructure to be installed once for multiple potential users while the charging units are only deployed where and when needed. This enables phased investment rather than requiring complete installation for all locations simultaneously

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The standardized wall socket with differential voltage protection serves as a universal base infrastructure that can support multiple different charging station units. This multi-functional design allows a single electrical infrastructure installation to serve numerous users over time, reducing the need for duplicate infrastructure investments

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

3Adaptability or versatility

If additional data interfaces and IT infrastructure are installed for smart wallboxes, then communication and load management capabilities are improved, but installation costs and complexity increase

Engineering Contradiction:
Improvecommunication capabilityVSAvoidIT infrastructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The charging unit acts as an intermediary device that provides necessary communication interfaces and data processing capabilities without requiring complex centralized IT infrastructure. By distributing intelligence to the edge device (charging unit), the system achieves smart functionality while minimizing the need for elaborate backend IT systems

Inventive Principle:
Principle #24Intermediary (Mediator)
