Vending Machine Shelf Partition Dynamics for Product Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic vending machines with slant racks face issues with product clogging due to odd-shaped items, particularly when products change posture, leading to interference with stopper members and difficulty in discharging products, especially when clogging occurs further back in the rack, requiring manual intervention and potential removal of the entire rack for resolution.
Innovation Solution
The design includes a product housing rack with tilted shelves and detachable shelf members, featuring a product discharge device with stopper members and a link mechanism, and a posture control plate to manage product orientation and prevent clogging, allowing for easy adjustment of partition members to accommodate different product sizes and shapes, ensuring smooth discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If products with odd shapes are housed in the product housing path, then product diversity is improved, but product clogging occurs due to posture changes interfering with stopper members
Solution Approach 1:
The partition member is made movable between a first position where it defines the product housing path and a second position where it facilitates product removal. This dynamic adjustment allows the system to adapt to different product shapes while maintaining reliable discharge by clearing clogged products when needed.
Solution Approach 2:
The partition member can be automatically positioned to facilitate product removal when clogging is detected, enabling the system to self-correct discharge issues without requiring external manual intervention for routine maintenance.
2Stability of the object's composition
If the partition member is fixed to define the product housing path, then product housing stability is improved, but manual intervention and rack removal are required to resolve clogging
Solution Approach 1:
The partition member transitions from a fixed structure to a dynamically adjustable component that can move between defining the product housing path and facilitating product removal, resolving clogging without rack removal.
Solution Approach 2:
The product housing rack is divided into separable components, with the partition member being an independently movable element that can be repositioned without affecting the entire rack structure, enabling localized intervention for clogging.
3Extent of automation
If stopper members are used to hold products in the product housing path, then product discharge control is improved, but odd-shaped products interfere with stopper member operation
Solution Approach 1:
The partition member's movable design complements the stopper members by providing an additional degree of freedom. When odd-shaped products interfere with stopper operation, the partition member can be repositioned to clear the interference while maintaining automated discharge control.
Solution Approach 2:
The partition member acts as an intermediary element between the stopper members and odd-shaped products, mediating conflicts by being repositioned to eliminate interference while allowing both the stopper members and diverse products to coexist in the system.

AI summary
An automatic vending machine includes a product housing rack including a plurality of product housing shelves that are disposed in an up-down direction, a plurality of product housing paths corresponding to the plurality of product housing shelves, each product housing path being defined in the corresponding product housing shelf and configured to house products, a plurality of product discharge devices corresponding to the plurality of product housing shelves and the plurality of product housing paths, each product discharge device being configured to separate and discharge, one by one, the products that are housed in the corresponding product housing path. The product housing shelf includes a front side shelf member and a back side shelf member that are divided in the front-back direction, supported by support members, and detachably coupled with each other so that the front side shelf member is sandwiched by the back side shelf member.
