Solution Overview

Problem

Existing battery cell formation plants face challenges in efficiently reconfiguring their layout to increase production capacity without incurring high costs or compromising transport accuracy.

Innovation Solution

The solution involves a modular transport system with passive modules that can be easily reconfigured by changing the coupling between modules, decoupling transport accuracy from tray positioning, and using high-precision conveyors only where necessary.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional routing system with fixed transport tracks is used, then transport accuracy is maintained, but reconfiguration cost and complexity increase

Engineering Contradiction:
Improvereconfiguration capabilityVSAvoidrouting system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The routing system is divided into independent modular units (robots with degrees of freedom) that can be individually configured and repositioned. Each module operates autonomously within the rack structure, allowing flexible reconfiguration without redesigning the entire system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from fixed transport tracks to dynamic, programmable robot actuators that can adapt their positions and movements. The robots include configurable degrees of freedom that allow the system to dynamically reconfigure its routing paths based on production needs.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If high-precision conveyors are used throughout the entire routing system, then transport accuracy is maintained, but system cost increases

Engineering Contradiction:
Improvetransport accuracyVSAvoidsystem cost
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

High-precision control is applied locally only at critical points where trays are transferred to formation chambers, rather than throughout the entire transport system. The robot actuators provide precision positioning at transfer points while using simpler, more cost-effective mechanisms for intermediate transport segments.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If the routing system is designed for high reconfigurability, then adaptability improves, but positioning precision may deteriorate

Engineering Contradiction:
Improvelayout reconfigurabilityVSAvoidtray positioning precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The robot actuators incorporate feedback control systems that use sensors to detect tray positions and adjust their movements accordingly. This closed-loop control ensures precise positioning even as the system configuration changes during reconfiguration, maintaining accuracy despite the flexible modular design.

Inventive Principle:
Principle #23Feedback
