Solution Overview

Problem

The installation of electric vehicle charging points at curbsides is costly and complex due to the need to manage existing utilities and requires excavation, leading to increased costs and greenhouse gas emissions.

Innovation Solution

A method is used to install an electrical cable in transfer modules that are as thick as the pavement stones and which are installed in a cable channel provided in a cable channel extending from a power source to an outlet at a curb, which are spaced by a sidewalk from a sidewalk to a cable from the sidewalk, where the cable is installed in a cable from the cable channel, allowing for power supply to an electrical outlet at a curb without excavation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If excavation work is performed to install power supply cables for curbside charging points, then power supply connectivity is achieved, but installation cost and complexity increase

Engineering Contradiction:
Improvepower supply connectivityVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sidewalk is divided into modular pavement stones that can be individually removed and replaced with transfer modules. This segmentation allows the cable channel to be installed through discrete modular units rather than requiring continuous excavation, thereby reducing installation complexity while maintaining power supply connectivity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Transfer modules serve as intermediary elements between the existing pavement stones and the cable installation. These modules contain pre-formed cable channels and can be easily installed by replacing individual pavement stones, acting as a mediator that simplifies the installation process while ensuring reliable cable routing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If excavation work is performed to install power supply cables, then power supply connectivity is achieved, but installation cost increases

Engineering Contradiction:
Improvepower supply connectivityVSAvoidinstallation cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The installation process is segmented into discrete steps where individual pavement stones are replaced with transfer modules. This eliminates the need for continuous excavation and allows for more efficient installation, reducing labor costs and material waste while ensuring reliable power supply connectivity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The transfer modules are designed as simple, easily replaceable components that can be installed without expensive specialized equipment. The modular design allows for quick installation and potential future replacement, reducing both initial installation cost and long-term maintenance costs while maintaining reliable cable routing.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Reliability

If excavation work is performed for cable installation, then power supply to curb outlets is achieved, but greenhouse gas emissions increase

Engineering Contradiction:
Improvepower supply connectivityVSAvoidgreenhouse gas emissions
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The cable installation process extracts only the necessary pavement stones for cable routing and leaves the rest of the sidewalk intact. This minimal intervention approach eliminates the need for extensive excavation, reducing the carbon footprint associated with heavy machinery operation and material transport while ensuring reliable power supply connectivity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The existing pavement stone structure, which initially seems to obstruct cable installation, is actually converted into an advantage. The modular pavement stones serve as ready-made access points for cable routing, eliminating the need for destructive excavation and reducing greenhouse gas emissions while achieving reliable power supply to curb outlets.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

4Reliability

If existing utilities are managed during curbside charging installation, then legal and technical compliance is achieved, but installation complexity increases

Engineering Contradiction:
ImprovecomplianceVSAvoidinstallation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The transfer modules are designed with cable channels positioned at specific locations that can be strategically selected to avoid existing utilities. This local customization of cable routing paths allows for compliance with utility management requirements while keeping the overall installation process simple and modular.

Inventive Principle:
Principle #3Local quality
