Portable Article Supply Device for Ground-Level Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article supply devices require users to lower their bodies to interact with the device, making them inconvenient for purchase transactions, especially when placed at low positions like the ground surface.
Innovation Solution
An article supply device with a body portion that includes a front, back, and bottom face, equipped with a holding portion allowing it to be lifted and held on the back or side of the user, featuring a cushioning member for comfort and adjustable belts for secure fit, enabling operation and product retrieval while mobile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the article supply device is placed at a low position such as the ground surface, then the device can be installed in various locations, but the purchaser needs to lower his/her body to purchase a product, reducing convenience
Solution Approach 1:
The patent applies the dynamics principle by making the device portable and movable. The article supply device is designed to be carried by a user rather than being fixed at a low position, allowing the device to be dynamically positioned at convenient heights for interaction while maintaining installation flexibility in various locations.
Solution Approach 2:
The patent transitions the device from a stationary ground-level installation to a portable handheld configuration. This dimensional change allows the device to be held at ergonomic heights for operation while maintaining the ability to be placed anywhere, resolving the contradiction between installation flexibility and operational convenience.
2Ease of operation
If the device is made portable and handheld, then user convenience and accessibility are improved, but the device complexity increases due to additional holding structures
Solution Approach 1:
The patent applies universality by designing the holding structure to serve multiple functions: it provides ergonomic support for handheld operation, enables portable carrying, and maintains structural integrity. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while improving ease of operation.
Solution Approach 2:
The patent merges the holding structure with the main body of the article supply device, integrating the carrying and operational functions into a unified design. This consolidation reduces the number of separate components and simplifies the overall device structure while maintaining portability and user convenience.

AI summary
An article supply device includes: a body portion including a front face portion, a back face portion, and a bottom face portion; an operating portion that is located on the front face portion and enables operation for supplying an article; and a supply port that is located on the front face portion and through which the article in the device can be supplied, in which the body portion can be held with the bottom face portion lifted. For example, the body portion is provided with a holding portion that enables the body portion to be held with the back face portion facing the front, the back, or a side of the torso of a human body.
