Solution Overview

Problem

Existing methods for managing battery storage do not adequately address the increased risk of storage due to damaged batteries, which can lead to ignition or leakage.

Innovation Solution

An information processing device and method that determine priorities for the collection of stored batteries based on information related to damage, such as accident history and storage duration, and output instruction information for prioritized collection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If damaged batteries are stored without priority collection, then storage capacity is maximized, but safety risk increases due to potential ignition or leakage

Engineering Contradiction:

Improvestorage safetyVSAvoidignition or leakage risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary assessment of battery damage status before storage, identifying damaged batteries in advance through information related to damage (accident history, storage duration). Collection priority is determined beforehand, allowing damaged batteries to be removed proactively before they can cause ignition or leakage, thus preventing harmful effects rather than responding after they occur.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies different collection priorities to different batteries based on their individual damage characteristics. Instead of uniform collection, the system evaluates each battery's accident history and storage duration separately, assigning high priority to batteries with longer storage durations or accident history, and lower priority to undamaged batteries. This differentiated approach optimizes safety by focusing resources on the most at-risk batteries.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If all batteries are collected equally without priority assessment, then collection process is simplified, but storage risk increases due to delayed removal of damaged batteries

Engineering Contradiction:

Improvecollection process simplicityVSAvoidstorage safety

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system introduces priority parameters (based on accident history and storage duration) to transform the collection process from a simple first-come-first-served approach to a risk-based prioritization system. By changing the assessment parameters from uniform to differentiated, the system maintains operational simplicity through automated evaluation while significantly improving safety through targeted collection of high-risk batteries.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The control unit automatically evaluates battery damage status and determines collection priorities without requiring manual assessment. The system uses stored information (accident history, storage duration) to self-assess which batteries need priority collection, reducing operational complexity while improving safety through consistent, data-driven decision-making.

Inventive Principle:

Principle #25Self-service
