Solution Overview

Problem

Existing multi-outlet charge stations for electric vehicles face challenges in accurate post placement due to obstacles like rocks or stones, leading to time-consuming and labor-intensive installation, high costs, and difficulty in adapting to different layouts.

Innovation Solution

A modular charging arrangement with elongated rails and connection elements that allow for flexible mounting on posts or walls, enabling easy assembly and expansion by allowing rail connectors to be secured at a connection distance with a large tolerance, and featuring sliding and locking mechanisms for efficient installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If posts are accurately located for multi-outlet charge stations, then the overground elements will fit properly, but the installation becomes time-consuming and labor-intensive

Engineering Contradiction:
Improvepost placement accuracyVSAvoidinstallation speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The charging station structure is divided into modular components (charging outlets, overground elements, support structures) that can be independently positioned and connected. This segmentation allows each module to be installed separately without requiring precise pre-positioning of all components, thereby improving installation speed while maintaining overall structural accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces adjustable mounting brackets and positioning mechanisms as intermediary elements between the posts and overground elements. These intermediaries provide tolerance adjustment capabilities, allowing proper fitting without requiring extremely precise post placement, thus resolving the contradiction between accuracy requirements and installation efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If posts are placed in exact locations, then the charging station layout is optimized, but obstacles like rocks or stones make post placement difficult or impossible

Engineering Contradiction:
Improvepost placement precisionVSAvoidadaptability to terrain obstacles
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The mounting system incorporates adjustable and movable components that can be positioned at various locations along the post structure. This dynamic positioning capability allows the charging outlets to be relocated if initial post placement is obstructed by terrain features, maintaining layout optimization while adapting to physical obstacles.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent employs adjustable mounting mechanisms that can modify positioning parameters (height, horizontal position, angle) of the overground elements relative to the posts. This parameter adjustability enables the system to compensate for post placement deviations caused by obstacles, preserving the intended charging station layout while accommodating terrain variations.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If traditional multi-outlet charge stations are installed, then charging functionality is provided, but the installation costs and labor requirements are high

Engineering Contradiction:
Improvecharging functionalityVSAvoidinstallation cost and labor
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The charging station is designed as an assembly of standardized modular units that can be manufactured separately and assembled on-site. This segmentation reduces manufacturing complexity and enables parallel installation of multiple modules, lowering both material costs and labor requirements while ensuring reliable charging functionality through proven modular designs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The overground elements and support structures are designed to serve multiple functions: structural support, cable protection, and mounting for charging outlets. This multi-functionality reduces the total number of components needed, simplifying both manufacturing and installation processes while maintaining full charging capabilities, thereby reducing overall installation costs and labor.

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