Side-Grip Textile Vending Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vending machines require textile items to be packaged for transfer from the storage area to the dispensing chute, increasing costs and time due to packaging materials and insertion processes.
Innovation Solution
A side-grip method and device that allows for the direct grasping and moving of textile items from the storage area to the dispensing chute without packaging, utilizing a vertically displaceable gripping element that grasps the item proximate to its edge, optionally with a support arm for securing the item during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If textile items are packaged for transfer from storage area to dispensing chute, then item protection and containment are improved, but operational time and expenses increase due to packaging insertion
Solution Approach 1:
The invention extracts the packaging step from the dispensing process by implementing a side-grip method that directly grasps and transfers textile items without packaging. The gripping element engages the item's edge and transports it through the dispensing chute, eliminating the need for packaging insertion while maintaining item protection during transfer
Solution Approach 2:
The gripping element acts as an intermediary mechanism between the storage area and dispensing chute, providing direct contact and transfer of the textile item without requiring packaging. The side-grip method uses this intermediary to bridge the gap between storage and dispensing while protecting the item through controlled grasping and transport
2Reliability
If textile items are packaged for transfer, then item containment is improved, but operational expenses increase due to packaging materials
Solution Approach 1:
The invention removes the packaging material requirement from the system by implementing direct grasping and transfer. The side-grip method eliminates packaging material costs while maintaining item containment through the gripping element that secures the item during transport from storage to dispensing
Solution Approach 2:
The textile item itself serves as the containment medium through its folded structure, which the gripping element engages. The item's own geometry and folding pattern provide the necessary containment without requiring external packaging materials, reducing operational expenses
3Manufacturing precision
If a gripping element grasps the textile item proximate to an edge, then grasping precision is improved, but item stability during transport may be compromised
Solution Approach 1:
The gripping element applies force locally at the edge of the textile item, providing precise grasping control. The side-grip method concentrates the gripping force at a specific location (the edge) while the item's folded structure distributes the load, maintaining both precision and stability during transport
Solution Approach 2:
The gripping element is designed with a curved or contoured surface that complements the edge geometry of the folded textile item. This curvature allows the gripper to wrap around and secure the item's edge, providing both precise positioning and stable transport by distributing contact pressure along the curved interface

AI summary
A side-grip method of grasping and moving textile items in a vending machine from the storage area to the dispensing chute that does not require the textile item to be packaged comprising: (a) providing a stack of folded and unwrapped textile items; (b) providing an article selection mechanism configured with a gripping element; (c) vertically displacing said gripping element until said gripping element reaches a level of a top textile item in said stack; and (d) closing said gripping element solely on said textile item. Disclosed also is a vending machine configured to implement such a method.
