Solution Overview

Problem

Users face a significant burden in ensuring the safety of power storage devices due to the changing safety conditions caused by usage and installation factors, which are not considered in type approval certifications based on design alone.

Innovation Solution

A processing system comprising a monitoring apparatus and a certification apparatus that acquires measurement data from power storage devices, calculates safety item values, and determines safety based on these values, providing certification information to users, thereby reducing the user's burden in ensuring safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If type approval certification based on design is performed, then certification efficiency is improved, but safety assurance after use deteriorates

Engineering Contradiction:
Improvecertification efficiencyVSAvoidsafety assurance after use
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system performs preliminary safety assessments during design phase through type approval, then continues monitoring during actual use. Measurement devices track operating conditions (temperature, charge/discharge cycles, current) and compare them against pre-established safety thresholds to proactively identify potential safety issues before they manifest as actual hazards.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements continuous feedback loops where measurement data from power storage devices during use is fed back to the certification system. This feedback mechanism allows the system to update safety assessments based on actual operating conditions, comparing real-time measurements against safety standards and notifying users when thresholds are approached or exceeded.

Inventive Principle:
Principle #23Feedback

2Reliability

If users monitor safety themselves, then safety awareness is improved, but user burden deteriorates

Engineering Contradiction:
Improvesafety awarenessVSAvoiduser burden
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The power storage device incorporates built-in measurement devices and safety monitoring systems that automatically track their own operating conditions. The device self-monitors parameters such as temperature, charge state, and current flow, and autonomously compares these against safety thresholds without requiring user intervention or specialized knowledge.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces an intermediary monitoring system that acts as a bridge between the complex technical parameters of power storage devices and the end user. This intermediary layer processes raw measurement data, interprets safety conditions, and presents simplified safety status information to users, shielding them from technical complexity while maintaining safety awareness.

Inventive Principle:
Principle #24Intermediary (Mediator)
