Bag Picking Aid for Stable Goods Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for picking goods into bags are hindered by difficult bag operation, the need for special boxes, and instability of bags during transportation, which can lead to damage of sensitive goods, especially under acceleration.
Innovation Solution
A method where a picking aid is inserted into the bag to hold the filling opening open during the picking process, enhancing the bag's stability and facilitating rapid and reliable operation, and allowing the bag to maintain stability during transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a picking aid is inserted in the bag to hold the opening open, then the picking operation becomes easier and faster, but the device complexity increases
Solution Approach 1:
The picking aid is divided into distinct functional segments: an insertion portion that enters the bag, a holding portion with protrusions that grip the bag opening, and a removal portion. This segmentation allows each part to perform its specific function efficiently while keeping the overall structure simple and manageable.
Solution Approach 2:
The picking aid serves as an intermediary tool between the operator and the bag. It mediates the interaction by providing a mechanical advantage for holding the bag opening open and facilitates the picking operation without requiring direct manual manipulation of the bag itself, thereby improving efficiency.
2Ease of operation
If special box-shaped loading aids with holding devices are used, then bags can be held open for filling, but the operation becomes more difficult and time-consuming
Solution Approach 1:
The picking aid is pre-configured with protrusions positioned to engage with the bag opening. Before the filling operation begins, the aid is inserted and automatically positions itself to hold the opening open, eliminating the need for complex setup procedures and reducing the time required for the loading process.
Solution Approach 2:
The function of holding the bag opening open is extracted from the complex box-shaped loading aid and embodied in the simple, removable picking aid. This extraction allows the essential function to be performed by a minimalistic device that can be quickly inserted and removed without the overhead of elaborate holding mechanisms.
3Loss of substance
If thin material bags are used to minimize packaging material, then material usage is reduced, but the bags cannot prevent damage to goods during high acceleration transport
Solution Approach 1:
The picking aid acts as an intermediary structural element inside the thin-material bag. It provides the necessary rigidity and support to maintain the bag's shape and protect the contents during high acceleration transport, while the thin bag material itself remains minimal for packaging efficiency. The aid mediates between the weak bag material and the need for structural integrity.
Solution Approach 2:
The picking aid provides localized structural reinforcement exactly where needed - at the opening and upper portions of the bag that experience the most stress during handling and transport. This allows the bag material to remain thin and minimal elsewhere, achieving protection where required without unnecessary material usage throughout the entire bag structure.
