Solution Overview

Problem

The expansion of electric vehicle charging infrastructure is hindered by complex and costly installation processes requiring multiple trades, leading to prolonged construction times and increased organizational efforts.

Innovation Solution

A modular charging station design where the distribution grid operator can independently install the station up to the grid connection fuse, with integrated charging electronics housed in a column and floor foundation, allowing for a single assembly and electrical connection, eliminating the need for separate installation of charging electronics by a qualified electrician.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the charging station is installed using multiple trades (electrician, civil engineer, fitter), then the installation is completed with proper specialization, but the construction process is lengthened and costs are increased

Engineering Contradiction:
Improveinstallation qualityVSAvoidconstruction time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent combines the charging station column and floor foundation into a single pre-assembled unit that can be installed by one trade (the distribution grid operator) rather than requiring multiple specialized trades. The integrated design allows the column to be directly placed on the foundation without separate installation steps, reducing construction time while maintaining installation quality through standardized assembly procedures.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If the charging station is installed using multiple trades, then each component can be installed by specialists, but the organizational effort is considerably increased

Engineering Contradiction:
Improveinstallation qualityVSAvoidorganizational complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the floor foundation and charging station column into a single installable unit, eliminating the need for multiple trades and reducing organizational complexity. The distribution grid operator can independently complete the entire installation process without coordinating with electricians, civil engineers, or fitters, thereby simplifying project management while maintaining installation quality through standardized procedures.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If the charging station is made available as a complete assembly, then the installation process is simplified and costs are reduced, but the manufacturing complexity increases

Engineering Contradiction:
Improveinstallation easeVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent segments the charging station into modular components (column, floor foundation, charging electronics) that are pre-assembled in a controlled manufacturing environment. This allows for standardized production of individual modules that can be easily combined during installation, reducing on-site complexity while managing manufacturing complexity through modular design and standardized interfaces.

Inventive Principle:
Principle #1Segmentation

4Ease of manufacture

If the opening in the column is provided for charging electronics, then the charging electronics can be easily installed, but the structural integrity of the column may be compromised

Engineering Contradiction:
Improveelectronics installation easeVSAvoidcolumn strength
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The patent applies local quality by providing openings in specific locations on the column where charging electronics need to be accessed, while maintaining the overall structural integrity of the column through strategic placement and sizing of openings. The column design incorporates reinforcement around opening areas to ensure strength is not compromised, allowing easy electronics installation while preserving structural requirements.

Inventive Principle:
Principle #3Local quality
