Solution Overview

Problem

Conventional vending machines are too large and bulky, making it difficult to position them in high-traffic areas like school or office hallways, resulting in lost sales opportunities due to space constraints.

Innovation Solution

A compact vending machine design with a housing that is no more than eight inches deep, allowing wall mounting and featuring a hinged front cover, non-cash payment system, and a product storage cartridge that can be easily replaced or refilled, with options for coil or vertical dispensing mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If conventional vending machines are used, then product dispensing function is provided, but the machine size is too large to position in high-traffic areas

Engineering Contradiction:
Improvevending machine sizeVSAvoidpositioning convenience
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The vending machine is divided into separate functional modules: a housing unit, a product storage cartridge, and a dispensing mechanism. This segmentation allows the main housing to be compact while the product cartridges can be easily replaced or refilled, solving both the size constraint and the positioning convenience issue in high-traffic areas

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from traditional floor-standing vending machines to wall-mounted or overhead installations by utilizing vertical space and mounting surfaces. This dimensional change allows the vending machine to occupy minimal floor space while remaining accessible to customers in high-traffic corridors and hallways

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Volume of moving object

If compact size is achieved, then positioning in high-traffic areas is enabled, but product storage capacity is reduced

Engineering Contradiction:
Improvevending machine sizeVSAvoidproduct storage capacity
Core Design Contradiction:
Volume of moving objectVSQuantity of substance

Solution Approach 1:

The product storage system is segmented into multiple interchangeable cartridges, each containing different products. This allows the compact housing to accommodate multiple product types through cartridge replacement rather than requiring large internal storage space, effectively increasing product variety and capacity within the compact form factor

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The product storage cartridges are designed as universal, interchangeable units that can be removed and replaced easily. This multi-functionality allows the same cartridge slots to accommodate different product types and sizes, maximizing storage capacity utilization within the compact housing without requiring dedicated spaces for each product category

Inventive Principle:
Principle #6Universality (Multi-functionality)
