Cable Reel Shelf Automation for Inventory Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cable drum rack management is labor-intensive and uncertain, leading to inefficiencies and high capital tie-up due to the need for regular inventory monitoring and large storage spaces to avoid availability gaps.
Innovation Solution
An automated method and rack system equipped with measuring and processing units that determine the remaining cable quantity after removal, comparing it to a minimum target stock value, and triggering orders when necessary, using wireless communication and sensors to minimize personnel effort and ensure continuous supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional manual inventory monitoring is used, then personnel can manage cable drum racks, but labor expenditure is high and uncertainty in stock management occurs
Solution Approach 1:
The cable drum rack system performs self-monitoring of cable quantities through integrated measuring units and processing units, eliminating the need for manual inventory checks by warehouse managers. The system automatically detects cable removal, measures remaining quantities, and triggers replenishment orders without human intervention.
Solution Approach 2:
Manual mechanical inventory checking is replaced with automated electronic measurement systems. The measuring units (such as weight sensors or level sensors) and processing units automatically detect and measure cable quantities, substituting the mechanical manual inspection process with electronic automation.
2Reliability
If complete cable drums are stored in addition to opened drums, then security of supply is improved, but additional space is required and capital is tied up
Solution Approach 1:
The system continuously monitors cable quantities on drums and provides feedback to the processing unit. When the remaining quantity falls below a predetermined threshold, the system automatically triggers a replenishment order, ensuring supply security without requiring excessive buffer stock.
Solution Approach 2:
The system changes the management parameter from static buffer stock levels to dynamic threshold-based replenishment. By setting predetermined quantity thresholds and automatically ordering when exceeded, the system optimizes storage space while maintaining supply security.
3Reliability
If complete cable drums are stored in addition to opened drums, then security of supply is improved, but capital is tied up
Solution Approach 1:
The system continuously monitors cable quantities on drums and provides feedback to the processing unit. When the remaining quantity falls below a predetermined threshold, the system automatically triggers a replenishment order, ensuring supply security without requiring excessive buffer stock.
Solution Approach 2:
The system changes the management parameter from static buffer stock levels to dynamic threshold-based replenishment. By setting predetermined quantity thresholds and automatically ordering when exceeded, the system optimizes inventory levels while maintaining supply security.
4Measurement precision
If measuring units and processing units are continuously active, then real-time monitoring is achieved, but energy consumption increases
Solution Approach 1:
The measuring units and processing units operate periodically rather than continuously. The system activates measurement and processing functions when cable removal is detected or at predetermined intervals, then enters low-power standby or idle mode when no activity occurs, reducing overall energy consumption while maintaining monitoring capability.

AI summary
The method serves to manage a cable drum rack (1) which includes at least one storage space for at least one cable drum (2) on which a cable (9) is wound, from which a consumer can take cable pieces of appropriate length as required.According to the invention, the cable drum rack (1) comprises at least one measuring unit (3; 4; 5) and one processing unit (6), by means of which a value for the remaining quantity of cable (9) on the cable drum (2) is determined directly or indirectly with each cable removal, wherein a) after the cable removal, at least one state variable of the cable drum (2) is measured and a value for the remaining quantity of cable (9) is calculated from this, or b) during the cable removal, the quantity of cable removed is measured and a value for the quantity removed is determined, and based on this, a value for the remaining quantity of cable (9) is calculated starting from a registered value of the remaining quantity before the cable removal. The value of the remaining quantity of cable (9) is then compared with a minimum target inventory value, and if this minimum target inventory value is undershot, an order (60) for the monitored cable (9) is triggered.
