Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing packaging units with multiple items fail to align them in a desired orientation without opening the packaging, limiting the presentation of brand and advertising messages.
Innovation Solution
A device and method that align items within packaging units using detection means and a gripper head to rotate them around their longitudinal axis, ensuring a desired appearance, even after they are mechanically held together by a packaging means, allowing for external visibility of information carriers like barcodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If items are aligned before grouping with packaging material, then alignment precision is improved, but the process complexity increases and continuous production is hindered
Solution Approach 1:
The patent applies preliminary action by performing alignment after grouping but before final packaging completion. The detection device scans item features and the adjustment mechanism orients items correctly while they are still accessible, ensuring precise alignment without requiring complex pre-alignment equipment.
Solution Approach 2:
The patent inverts the conventional sequence by grouping items first with packaging material and then aligning them. This reversal allows simpler grouping mechanisms to handle the bulk material while dedicated detection and adjustment systems handle the alignment, reducing overall process complexity.
2Ease of manufacture
If items are aligned after grouping with packaging material, then process simplicity is improved, but alignment precision deteriorates
Solution Approach 1:
The patent introduces an intermediary detection device that scans item features (barcodes, labels) after grouping and determines the correct orientation. This intermediary system bridges the simple grouping process and the alignment requirement, enabling precise orientation through feature recognition and controlled adjustment.
Solution Approach 2:
The patent replaces complex mechanical pre-alignment systems with a combination of detection technology (optical sensors, scanners) and controlled adjustment mechanisms. This substitution allows alignment to be achieved through sensing and actuation rather than complex mechanical guides, simplifying the overall system.
3Adaptability or versatility
If detection and alignment mechanisms are added to achieve desired item orientation, then product presentation is improved, but device complexity increases
Solution Approach 1:
The detection device serves multiple functions: it identifies item features, determines correct orientation, and provides data to the control system. This multi-functionality reduces the need for separate alignment measurement systems, thereby limiting the increase in device complexity while achieving versatile product presentation.
Solution Approach 2:
The system uses the items' own features (barcodes, labels, geometric characteristics) as alignment references. The detection device reads these self-contained features and the adjustment mechanism uses them to achieve correct orientation, eliminating the need for external alignment templates or additional reference systems.
4Productivity
If continuous production process is implemented, then productivity is improved, but alignment control precision deteriorates
Solution Approach 1:
The patent implements continuous production by integrating detection, control, and adjustment mechanisms that operate continuously along the production line. The detection device continuously scans item features, and the adjustment mechanisms continuously correct orientations without interrupting the flow, maintaining both productivity and precision.
Solution Approach 2:
The control system receives real-time data from the detection device about item features and current orientation, processes this information, and sends adjustment commands to the alignment mechanisms. This closed-loop feedback system ensures precise alignment control even in continuous production where conditions may vary.
