Solution Overview

Problem

Existing battery production lines face inefficiencies due to the need to stop and restart when cladding materials in storage bins are depleted, leading to reduced production efficiency.

Innovation Solution

A bare cell encasing production line with a conveying module and assembly module that includes multiple preparation assemblies, allowing the feeding mechanism to switch between assemblies to ensure continuous operation by maintaining at least one assembly with cladding material, and a transfer mechanism to facilitate non-stop operation of shell material preparation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single storage bin is used to store cladding material, then the device complexity is low, but the production line must stop when the material is depleted, reducing productivity

Engineering Contradiction:
Improveproduction efficiencyVSAvoidnumber of preparation assemblies
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The single storage bin is segmented into multiple storage bins (first storage bin, second storage bin, etc.), each associated with a separate preparation assembly. This segmentation allows the system to switch between multiple material sources, preventing production stoppage when one bin is depleted while keeping each individual bin simple in structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple preparation assemblies are merged into a single coordinated system with a unified feeding mechanism that can switch between different storage bins. The control system merges the operation of multiple independent assemblies into a cohesive production flow, maintaining high productivity while managing the complexity through centralized control.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If the production line stops to replenish cladding material, then the device complexity remains low, but time is lost and productivity decreases

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoiddowntime for replenishment
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

Multiple storage bins are prepared in advance with cladding materials before production begins. When one bin is depleted, the system can immediately switch to a pre-prepared bin without stopping the production line, eliminating downtime for material replenishment while maintaining continuous operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous useful action by implementing a switching mechanism between multiple preparation assemblies. When one assembly's material is depleted, the feeding mechanism automatically or manually switches to another assembly, ensuring the production line continues operating without interruption and maximizing productivity.

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If multiple preparation assemblies are used to ensure continuous operation, then productivity improves, but the device complexity increases

Engineering Contradiction:
Improveproduction efficiencyVSAvoidstructure of conveying module
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The feeding mechanism is designed with multi-functionality, capable of working with multiple different preparation assemblies and storage bin configurations. This universal design allows the system to achieve continuous production through multiple assemblies while keeping the feeding mechanism itself relatively simple and adaptable, rather than requiring complex dedicated mechanisms for each assembly.

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