Solution Overview

Problem

Existing electric vehicle charging stations are inflexible in terms of external appearance modification and can be difficult to locate, especially in public settings, lacking effective visual indicators for charging status.

Innovation Solution

A modular charging station design comprising a removable cap that can be interchanged with a standard, versatile box containing electrical functions, allowing for adaptable appearance and incorporating visible light indicators for charging status.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the charging station is designed as an integral part of an architectural structure, then it provides shelter for the vehicle, but it becomes expensive, bulky and difficult to adapt to other parking configurations

Engineering Contradiction:
Improveadaptability to different parking configurationsVSAvoidcomplexity of integral architectural structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The charging station is segmented into a separate autonomous terminal that can be independently positioned and configured, rather than being integrated into a fixed architectural structure. This allows the terminal to be placed in various parking configurations without requiring complex structural integration.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The autonomous terminal is designed with universal applicability to different parking configurations and vehicle types. The standardized terminal design can serve multiple purposes and be adapted to various locations without requiring custom architectural integration for each installation.

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

2Adaptability or versatility

If the charging station external appearance is fixed, then the electrical equipment configuration remains stable, but it becomes impossible to modify the external appearance without in-depth redesign

Engineering Contradiction:
Improveability to modify external appearanceVSAvoidcomplexity of electrical equipment configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The charging station is divided into separate functional modules: the autonomous terminal housing and the electrical equipment components. This segmentation allows the external appearance of the terminal to be modified independently without affecting the internal electrical equipment configuration, enabling aesthetic updates while maintaining functional stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The terminal is designed with a universal standardized interface that separates the external housing from the electrical components. This allows different external designs to be applied to the same functional core, enabling appearance modifications without requiring redesign of the electrical equipment configuration.

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

3Ease of operation

If the terminal is placed in a public car park, then it serves multiple vehicles, but it becomes difficult to locate from a distance

Engineering Contradiction:
Improvevisibility and locatability of terminalVSAvoidcomplexity of visual indication system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The terminal incorporates light sources that emit visible light through non-opaque zones in the cap, creating luminous indications that can be seen from a distance. These color-coded or intensity-coded lights make the terminal easily locatable in public parking areas and provide visual feedback on charging status.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The cap with its non-opaque zones acts as an intermediary that transmits light from internal sources to external observers. This intermediary structure enables the light indication function without requiring complex external signage or display systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If the cap is made entirely opaque, then it provides complete protection and aesthetic coverage, but it prevents visibility of light indicators for charging status

Engineering Contradiction:
Improvevisibility of charging statusVSAvoidprotection and aesthetic coverage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cap is designed with differentiated local properties: most of the cap surface is opaque for protection and aesthetics, while specific localized zones are non-opaque to allow light transmission. This local quality variation enables the cap to simultaneously provide protection and display charging status information through visible light indicators.

Inventive Principle:
Principle #3Local quality
