Switchable Dispenser Routing for In-Line Battery Segment Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the energy-cell manufacturing industry, there is a need to remove individual product segments such as electrode sheets, separator sheets, or monocells from the production process for quality testing and calibration, while ensuring that defective connection points (splices) do not reach the end product, and to enable flexible routing of product flows.
Innovation Solution
A device with a switchable dispenser controlled by a machine controller allows for the removal and branching of product segments from the production flow, utilizing a switchable vacuum or compressed air system to divert segments for testing, calibration, and removal of splices, with a collecting device and buffer system to manage the removed segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual product segments are removed from the production process for quality testing and calibration, then measurement precision and quality control are improved, but productivity and production continuity are reduced
Solution Approach 1:
The system enables continuous removal and testing of product segments during ongoing production without stopping the manufacturing process. The automated dispenser and collection system operate concurrently with production, maintaining continuous useful action while enabling quality control measurements.
Solution Approach 2:
An intermediary collection container system is introduced between the production line and quality testing area. This mediator allows product segments to be transferred for testing without interrupting the main production flow, resolving the conflict between measurement needs and production continuity.
2Measurement precision
If the machine sensor system is calibrated using external measurement equipment, then measurement precision is improved, but device complexity and time requirements increase
Solution Approach 1:
The calibration function is extracted from the main production machine and placed in a separate, dedicated calibration device. This external calibration system can be simplified and optimized independently, reducing the complexity of the overall system while maintaining high measurement precision.
Solution Approach 2:
Instead of complex in-machine calibration equipment, the system uses simple reference objects with known properties that can be easily inserted into the production flow. These reference copies enable calibration without requiring sophisticated measurement infrastructure.
3Manufacturing precision
If product segments are removed frequently for quality testing, then manufacturing precision is improved, but loss of time and production efficiency worsen
Solution Approach 1:
Quality testing is performed preliminarily on individual segments during the production process rather than after complete assembly. This preliminary detection allows for early identification and correction of defects, reducing rework time and improving overall manufacturing precision.
Solution Approach 2:
The system implements rapid automated testing that quickly evaluates product segments and immediately returns them to the production flow if acceptable. This skipping approach minimizes the time each segment spends in testing, maintaining high manufacturing precision while reducing total testing time.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables efficient quality testing and calibration of internal sensors, quick identification and removal of defective splices, and minimizes disruption to the production climate by allowing for targeted removal and routing of product segments without requiring machine stoppages.
Implementation Method 1
a rotatably driven dispensing drum (52) which is set up to hold and transport at least one product segment (82) by means of suction on the lateral surface of the dispensing drum (52)
Implementation Method 2
a dispensing-side compressed air device (46) which is switchable by means of a valve (47) for guiding compressed air to a dispensing point (50) of the dispenser (63). The compressed air breaks or neutralises the vacuum produced by the vacuum device (41)
