Solution Overview

Problem

Existing mobility product charging apparatuses lack a self-extinguishing mechanism to prevent and control fires during charging and storage, posing a significant risk of fire spread and damage.

Innovation Solution

A mobility product charging apparatus with an integrated fire-extinguishing tank and discharge tubes connected to charging booths, which automatically injects a cooling agent to extinguish fires when detected, minimizing fire spread and damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a simple charging/storage type apparatus is used, then device complexity is reduced, but fire safety is insufficient and cannot self-extinguish fire

Engineering Contradiction:

Improvefire safetyVSAvoidapparatus structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the charging function and fire extinguishing function into a single integrated apparatus. The charging/storage apparatus includes charging slots for battery packs and a fire extinguishing tank with discharge tubes that can directly spray cooling agents onto the battery packs, merging safety functionality into the charging structure itself.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The apparatus is designed to automatically detect fires through temperature sensors and autonomously discharge cooling agents without requiring external firefighter intervention. The system self-monitors battery temperature during charging and self-activates the fire extinguishing mechanism when thermal runaway is detected.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If fire extinguishing equipment is not provided at charging locations, then ease of operation is improved, but fire risk increases and can cause entire building damage

Engineering Contradiction:

Improvecharging convenienceVSAvoidfire risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The apparatus pre-positions fire extinguishing equipment (fire extinguishing tank with cooling agents) at the charging location itself, before any fire incident occurs. The discharge tubes are pre-configured to directly target battery pack positions, ensuring immediate fire suppression capability is already in place when charging begins.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces a cooling agent (water or other suppressant) as an intermediary substance stored in the fire extinguishing tank. This cooling agent acts as a mediator between the detected fire and the suppression action, being delivered through discharge tubes directly to the battery pack to extinguish thermal runaway.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If running water or fire truck is used to extinguish battery fire, then fire extinguishing capability is provided, but extinguishing time is excessive and explosive power remains dangerous

Engineering Contradiction:

Improvefire extinguishing speedVSAvoidexplosive power

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the fire extinguishing function from external fire services and integrates it directly into the charging apparatus. The fire extinguishing tank and discharge tubes are built-in components that enable immediate on-site suppression, removing the time delay associated with calling external fire trucks.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system replaces manual fire fighting methods (fire trucks, hoses) with an automated mechanical discharge system. Temperature sensors detect thermal runaway and automatically trigger the discharge mechanism to spray cooling agents directly onto the battery pack, substituting human response with automated mechanical action.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Disclosed are a mobility product charging apparatus and method for self-extinguishing fire. According to an embodiment of the present disclosure, a mobility product charging apparatus with a fire-extinguishing function includes: a fire-extinguishing tank which is located at an upper portion and is for storing and moving a cooling agent for extinguishing fire; and one or more charging booths which are located at a lower portion and designed for charging and storing mobility products, wherein the fire-extinguishing tank and each of the one or more charging booths are connected through a discharge tube. When a fire occurs in a specific charging booth from among the one or more charging booths, charging of a mobility product in the specific charging booth is stopped, and a discharge lever corresponding to the specific charging booth is automatically opened so that the cooling agent is injected from the fire-extinguishing tank to the specific charging booth through the discharge tube and the fire-extinguishing function is performed.
