Solution Overview
Problem
Existing sack transport and stacking devices are inefficient in downstream processing, leading to slower processing times compared to sack production.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sacks are transported sequentially to subsequent processing stations, then the transport system remains simple, but the processing speed is limited by the slowest station
Solution Approach 1:
The transport system is segmented into multiple parallel conveyor tracks (first transport path and second transport path) that can operate independently. The dividing device separates the single stream of sacks into two separate streams, allowing simultaneous processing at different stations. This segmentation enables parallel processing without requiring complete system redesign.
Solution Approach 2:
The system transitions from a single-dimensional sequential transport to a two-dimensional parallel transport structure. By introducing a second transport path running parallel to the first, the system utilizes spatial dimensionality to enable simultaneous processing. The dividing device routes sacks to different paths, creating parallel processing flows that increase overall throughput.
2Loss of time
If a single stacking station processes all sacks sequentially, then the device complexity is low, but the time required for sack processing increases
Solution Approach 1:
The stacking function is segmented across multiple stations (first stacking station and second stacking station) positioned at different locations along the parallel transport paths. Each station processes a subset of sacks independently and simultaneously, dividing the total processing workload to reduce overall processing time and increase throughput.
3Productivity
If stacks of sacks are inspected and processed one at a time, then the inspection quality can be maintained, but the overall production efficiency decreases
Solution Approach 1:
The inspection process is segmented into multiple parallel inspection stations (first inspection station and second inspection station) positioned along the parallel transport paths. Each station performs inspection on separate stacks simultaneously, maintaining thorough inspection quality while multiplying the overall inspection capacity. This allows multiple stacks to be inspected in parallel rather than sequentially.
