Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vending machines have limited product storage capacity and stability due to their rectangular shape, which restricts mobility and increases the risk of tipping, especially when equipped with refrigeration units and heavy product loads.
Innovation Solution
A self-propelled vending machine with a wider base and angled product storage area, utilizing a serpentine product storage system that allows products to roll by gravity into an elevator shaft for dispensing, and equipped with sensors and processing units for user interaction and payment processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional rectangular vending machines are used, then they provide standard product storage, but they have limited storage capacity and increased risk of tipping
Solution Approach 1:
The vending machine employs an asymmetric triangular housing design with a wider base and angled walls, deviating from the conventional rectangular shape. This asymmetric geometry provides both expanded product storage capacity and enhanced stability by lowering the center of gravity and distributing weight more effectively across the wider base, thereby preventing tipping.
Solution Approach 2:
The patent introduces a diagonal elevator shaft that extends from the base to the top of the triangular housing, utilizing the vertical and diagonal dimensions efficiently. This dimensional approach allows product items to be transported from the wider base area up to the dispensing area at the top, maximizing space utilization while maintaining structural stability.
2Ease of operation
If conventional fixedly positioned vending machines are used, then they provide stable product dispensing, but they weigh a significant amount and lack mobility
Solution Approach 1:
The vending machine incorporates wheels at its base, transforming it from a static, fixedly positioned unit to a mobile, dynamic system. This enables the machine to be easily moved and repositioned as needed, significantly improving ease of operation and deployment flexibility without requiring heavy lifting equipment or permanent installation.
Solution Approach 2:
The triangular housing design with its wider base and angled walls creates a more efficient weight distribution pattern compared to conventional rectangular designs. This geometric parameter change reduces the overall weight requirement for structural integrity and stability, making the machine lighter and more mobile while maintaining adequate product storage capacity.
3Quantity of substance
If product items are stored in conventional rows or columns, then they are easily accessible, but storage capacity is limited
Solution Approach 1:
The product storage area is segmented into multiple levels or tiers within the triangular housing, with product items arranged in rows or columns on each level. This segmentation allows efficient use of the available space, maximizing storage capacity while maintaining organized, accessible arrangements that do not significantly increase system complexity.
Solution Approach 2:
The diagonal elevator shaft is nested within the triangular housing structure, utilizing the internal space efficiently. This nested configuration allows the elevator mechanism to be integrated into the housing without adding external complexity, while still providing enhanced product storage capacity through optimized spatial arrangement.
