Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Outdoor electric vehicle charging stations are vulnerable to precipitation, which can damage internal components due to inadequate drainage systems, leading to potential malfunction or failure.

Innovation Solution

The electric vehicle charging station incorporates a frame with a rotatable door, a gutter system, and a downspout to divert precipitation away from the charging station, utilizing a gasket for sealing and a deflector to guide water into the gutter, ensuring effective drainage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the charging station is installed outdoors with minimal cover to provide easy access, then ease of operation is improved, but the station becomes vulnerable to precipitation damage

Engineering Contradiction:

Improveaccess to charging stationVSAvoidprecipitation exposure

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

A gutter system acts as an intermediary component between the roof and the charging station interior. The gutter collects precipitation that bypasses the gasket seal and redirects it through a downspout away from the station, preventing water damage while maintaining outdoor accessibility

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a gasket seal is used between the door and frame to prevent precipitation entry, then protection against precipitation is improved, but water may still bypass the seal requiring additional drainage

Engineering Contradiction:

Improveprecipitation protectionVSAvoiddrainage system complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The gutter is positioned to intercept precipitation before it can reach critical electrical components. By placing the gutter at the roof edge and connecting it to a downspout, the system proactively redirects water away from the station, complementing the gasket seal rather than relying on it exclusively

Inventive Principle:

Principle #10Preliminary action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution effectively prevents water from entering the charging station's interior, protecting electrical components and maintaining functionality by redirecting precipitation through a gutter and downspout system.

Implementation Method 1

a gutter disposed at least partially within the interior space to divert precipitation away from the electric vehicle charging station

Methodology Applied

Scientific EffectGravity: Gravitation

Implementation Method 2

a gasket disposed between the door and the frame, where the gasket forms an at least partial seal between at least a portion of the frame and at least a portion of the door in the closed position

Methodology Applied

Scientific EffectSealing:

Implementation Method 3

a deflector disposed in the interior space under the top wall of the frame to deflect into the gutter any precipitation that enters the interior space

Methodology Applied

Scientific EffectFluid deflection:
