Vending Machine Lift Movable Wall Horizontal Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic vending machine lifts face limitations in product size, storage capacity, and operational efficiency due to physical constraints such as U-shaped vertical walls and the need for products to be rotated for extraction, leading to customer discomfort and potential blockages.
Innovation Solution
The automatic vending machine lift features a movable wall that can adapt to different positions, allowing products to be dispensed from a surface at the same height as the access door, enabling horizontal extraction and preventing unwanted access to the storage area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If U-shaped vertical walls are used in the lift to prevent product collision, then product security during movement is improved, but the maximum product height is limited and the lift size increases
Solution Approach 1:
The patent applies the dynamics principle by making the vertical wall movable rather than fixed. The wall can adapt its position between a first position (allowing product passage from storage tray to platform) and a second position (allowing product extraction while blocking access to storage trays). This dynamic adjustment resolves the contradiction by providing security when needed while allowing full product height access when the wall is repositioned.
2Ease of operation
If the product collection door is positioned at standard height, then ease of access is improved, but larger products cannot be dispensed without collision
Solution Approach 1:
The patent uses the dynamics principle by making the vertical wall movable to adapt to different product sizes. When a larger product needs to be dispensed, the wall moves to the first position allowing the product to pass through without collision. When security is needed, the wall moves to the second position. This resolves the contradiction between ease of access and product size capacity.
Solution Approach 2:
The patent applies segmentation by separating the product passage function from the security blocking function through the movable wall mechanism. The wall can be positioned in different locations to fulfill different functions, allowing the system to handle both large products and maintain security without compromise.
3Adaptability or versatility
If the lift ceiling is positioned high to accommodate large products, then product size capacity is improved, but storage capacity is reduced
Solution Approach 1:
The patent resolves this contradiction by making the vertical wall movable rather than having a fixed high ceiling. The wall dynamically adjusts its position based on the product being dispensed, allowing large products to pass through when needed while maintaining a compact overall lift structure that preserves storage capacity.
4Reliability
If the movable wall blocks access to storage trays, then security against theft is improved, but product extraction is limited
Solution Approach 1:
The patent applies dynamics by making the wall movable between two positions. In the second position, the wall blocks access to storage trays for security while still allowing product extraction through the collection door. In the first position, the wall allows free passage for product loading. This resolves the contradiction between security and ease of operation.

AI summary
The object of the invention is an automatic vending machine lift that makes it possible to dispense products from a surface arranged at the same height as the access door to the inside of the lift, so that the product is visible in its entirety before and during extraction, where the product does not need to be raised therein to remove it from the machine, but only dragged in a horizontal direction.
