Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bottling lines face challenges in increasing throughput and preventing misalignment of container rows, which affects the operation of manipulating means and can propagate over time, leading to inefficiencies in forming batches and layers of containers.
Innovation Solution
The unit employs a system of conveying lines with sensing means and control units to adjust speed profiles of conveyors, ensuring accurate separation and alignment of batches, using brushless motors and manipulating means like robots to form layers efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the unit processes two or more rows of groups of containers simultaneously, then the throughput increases, but misalignment between rows occurs and propagates over time
Solution Approach 1:
The patent employs sensing means (e.g., optical sensors, cameras) to detect the actual positions of batches in multiple rows, and a control unit processes this information to calculate misalignment. The system then adjusts conveyor speeds in real-time based on this feedback, preventing misalignment propagation while maintaining high throughput from multiple rows
Solution Approach 2:
The patent makes the conveyor system dynamic by allowing independent speed adjustment of each conveyor belt carrying different rows. The control unit varies conveyor speeds dynamically based on detected batch positions, enabling the system to adapt to misalignment conditions and maintain precise alignment across multiple rows simultaneously
2Ease of operation
If conveyors run at constant speed, then the operation is simple, but batches cannot be accurately aligned when misalignment occurs
Solution Approach 1:
The patent transitions from constant speed operation to dynamic speed variation. The control unit adjusts conveyor speeds based on real-time batch position detection, allowing the system to maintain simple constant speed operation during normal conditions while automatically varying speeds when alignment correction is needed
Solution Approach 2:
The patent changes the speed parameter of conveyors dynamically. The control unit modifies conveyor speeds as a corrective measure to realign batches, transforming the speed from a fixed parameter to a variable one that adapts to alignment requirements while maintaining overall operational simplicity
3Manufacturing precision
If additional alignment devices are added to correct misalignment, then the alignment precision improves, but the device complexity increases
Solution Approach 1:
The patent replaces mechanical alignment devices (such as physical guides, stoppers, or mechanical positioning mechanisms) with a control system that uses sensing means and variable speed control. This substitution reduces mechanical complexity while achieving precise alignment through intelligent speed adjustment of existing conveyors
4Productivity
If the unit processes multiple rows of groups, then the productivity increases, but the misalignment propagates over time
Solution Approach 1:
The patent implements continuous feedback monitoring of batch positions in multiple rows using sensing means. The control unit processes this feedback to detect misalignment trends and adjusts conveyor speeds proactively, preventing misalignment propagation over time while maintaining high throughput from multiple rows
Solution Approach 2:
The patent takes preliminary action by detecting and correcting misalignment early in the process. The control unit monitors batch positions continuously and adjusts conveyor speeds before misalignment can propagate significantly, maintaining alignment stability throughout the processing of multiple rows
