Bobbin Supply Lock for Climate-Stable Energy Cell Web Handling

Solution Overview

Problem

Existing production processes for energy cells face challenges in maintaining predefined climatic conditions during the cutting and stacking of segments, leading to inconsistencies in cell stack quality.

Innovation Solution

A device comprising a bobbin changing and handling system within an air-conditioning chamber, equipped with a lock to minimize air exchange, ensures consistent climatic conditions by using a bobbin handling device to transfer bobbins automatically, and a control unit to manage door openings, reducing energy consumption and maintaining climatic stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the air-conditioning chamber door is opened frequently to supply bobbins, then the bobbin handling efficiency is improved, but the climatic conditions inside the chamber deteriorate

Engineering Contradiction:

Improvebobbin handling efficiencyVSAvoidclimatic conditions stability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

Bobbins are pre-loaded into the air-conditioning chamber before the cutting and stacking process begins. This preliminary action ensures that multiple bobbins are already positioned and ready for use, eliminating the need to open the chamber door during the critical climatic process, thus maintaining climate stability while ensuring continuous productivity

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A lock mechanism is introduced as an intermediary device between the chamber interior and exterior. This lock allows for controlled access and bobbin supply while minimizing direct opening of the main chamber door, thereby reducing climate disruption and maintaining the stability required for high-quality cell stack production

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity
