Pharmaceutical Bag Gripping Element With Hook And Jaws
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gripping elements for pharmaceutical product bags can only securely hold the bag when the free edge is positioned underneath the other edge, preventing the bag from being tipped or held with the free edge over the other edge.
Innovation Solution
A gripping element with two substantially flat jaws to hold the first edge and a rigid L-shaped bracket with a hook to hold the second edge, allowing the bag to be oriented in both horizontal and vertical positions, with optional hinged jaws, RFID identification, and replaceable pliers or guiding rods for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gripping element uses two substantially flat gripping jaws hinged to each other, then the bag can be withheld at one edge, but the bag cannot be tipped or withheld with the second edge over the first edge
Solution Approach 1:
The gripping element is divided into two separate gripping devices: a first gripping device with hinged jaws for gripping the first edge, and a second gripping device with a hook for gripping the second edge. This segmentation allows each device to be optimized for its specific function while enabling versatile bag orientation.
Solution Approach 2:
The second gripping device with the hook structure provides multi-functionality by enabling the system to grip the bag in multiple orientations. The hook can engage with the second edge regardless of whether it needs to be positioned above or below the first edge, making the gripping element universal for different bag orientations.
2Device complexity
If the gripping element is designed to hold the bag in a fixed orientation, then the structure is simple, but the bag cannot be oriented in both horizontal and vertical positions
Solution Approach 1:
The gripping element is divided into two substantially flat gripping devices: a first gripping device with hinged jaws for gripping the first edge, and a second gripping device with a hook for gripping the second edge. This segmentation allows each device to be optimized for its specific function while enabling versatile bag orientation.
Solution Approach 2:
The hook structure of the second gripping device adds a new dimensional capability for engagement. Unlike the planar jaws that grip from above, the hook can engage from different directions and orientations, enabling the bag to be held in both horizontal and vertical positions without significantly increasing overall structural complexity.
