Solution Overview

Problem

The rapid increase in secondary battery production demand is outpacing the availability of skilled workers, and existing training methods are inadequate for quickly responding to various defect situations in battery production plants, leading to inefficiencies and losses.

Innovation Solution

A VR-based simulation method and device that utilizes a head-mounted display and controllers to simulate secondary battery production processes, allowing users to practice operations and respond to defects in a virtual environment, with scenarios including electrode replacement, separator replacement, quality checks, and defect handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional on-the-job training methods are used, then workers can learn from skilled workers directly, but training cannot be conducted for long periods due to busy production schedules and workers cannot respond quickly to defect situations

Engineering Contradiction:
Improveworker response capability to defectsVSAvoidtraining duration
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements VR-based simulation training that allows workers to practice defect handling scenarios in advance before encountering real defects. The system pre-loads various defect scenarios (electrode replacement, separator replacement, quality checks) into the virtual environment, enabling workers to perform preliminary training actions without interrupting actual production schedules. This resolves the contradiction by separating training time from production time while maintaining training effectiveness.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates a virtual copy of the secondary battery production plant that replicates real equipment, processes, and defect scenarios. This virtual replica allows workers to practice handling defects repeatedly without affecting real production. The copying principle resolves the contradiction by providing an unlimited training environment that mirrors reality without consuming actual production resources or time.

Inventive Principle:
Principle #26Copying

2Productivity

If the number of production plants is increased to meet demand, then production capacity increases, but the number of skilled workers becomes insufficient

Engineering Contradiction:
Improvesecondary battery production capacityVSAvoidskilled worker availability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The VR training system enables workers to self-train on defect handling procedures without requiring constant supervision from skilled workers. The system provides automated guidance, scenario selection, and performance evaluation, allowing workers to independently improve their capabilities. This resolves the contradiction by reducing the dependency ratio between skilled and unskilled workers, enabling rapid scaling of production capacity without proportional increases in skilled worker numbers.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary training preparation by pre-configuring multiple defect scenarios and training modules in the virtual environment. Workers can complete foundational training beforehand, reducing the burden on skilled workers during actual operations. This allows production plants to scale up faster than the natural rate of skilled worker development.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If general operation training is provided, then workers learn basic plant operations, but they cannot immediately respond to various defect situations

Engineering Contradiction:
Improvebasic operation capabilityVSAvoiddefect response capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The VR training system dynamically adapts to worker needs by providing different defect scenarios based on progress and performance. The system transitions from static general operation training to dynamic defect-specific training, adjusting scenario difficulty and type in real-time. This resolves the contradiction by making the training system flexible enough to provide both basic operation skills and specialized defect response capabilities within a unified platform.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The VR training platform serves multiple functions: it teaches basic operations, simulates various defect scenarios, provides real-time feedback, and tracks worker progress all within a single system. This multi-functional approach resolves the contradiction by consolidating general training and specialized defect response training into one adaptable system that can address both needs simultaneously.

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