Solution Overview

Problem

Traditional vending machines lack a sophisticated user interface, providing a cold and impersonal experience, leading to increased human error and inefficiency in product selection, especially for upscale products, due to limited interaction with physical products and reliance on virtual representations.

Innovation Solution

An enhanced vending machine with motion and pressure sensors, combined with programmable LED lighting and touch screen displays, allowing users to interact with products by touch, simulating natural gestures and providing intuitive product selection and information retrieval, while dynamically responding to user presence and gestures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional mechanical selection systems (levers, buttons, pull posts) are used, then device complexity is reduced, but ease of operation deteriorates due to non-intuitive product selection

Engineering Contradiction:
Improveintuitive product selectionVSAvoidselection system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical selection systems (levers, buttons, pull posts) with a touch-sensitive interface that detects user gestures and touches. The touch-sensitive display allows users to directly interact with product images and information on the screen, eliminating the need for separate mechanical selection components and creating a more intuitive one-to-one correspondence between selection action and product identification.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses virtual representations (images and digital information) of physical products displayed on the touch-sensitive screen. Users interact with these digital copies by touching the screen, which then corresponds to the actual physical product location. This copying approach allows intuitive selection through direct contact with the product image rather than requiring users to understand mechanical selection mechanisms.

Inventive Principle:
Principle #26Copying

2Ease of operation

If virtual touch screen interfaces are used, then ease of operation improves, but reliability deteriorates due to disconnection between touch location and physical product location

Engineering Contradiction:
Improveproduct selection easeVSAvoidproduct selection accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements a feedback system where the touch-sensitive display provides visual feedback by highlighting or indicating which physical product corresponds to the touched location. The system processes the touch coordinates and provides confirmation feedback to the user, ensuring accurate mapping between the virtual interface and physical product location, thereby reducing selection errors.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent uses the touch-sensitive display as an intermediary that directly corresponds to the physical product display behind it. The display acts as a mediator that translates user touches into precise product selections by maintaining spatial alignment between the virtual interface and physical products, reducing the disconnect between selection action and product identification.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If standard lighting and display mechanisms are used, then device complexity is reduced, but adaptability deteriorates in providing depth of product information

Engineering Contradiction:
Improveproduct information depthVSAvoiddisplay system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a multi-functional display system where the touch-sensitive screen serves multiple purposes: displaying product images, providing detailed product information, enabling product selection, and offering interactive controls. This universal interface consolidates multiple display and interaction functions into a single system, providing depth of information while maintaining ease of use through a unified interface.

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

4Productivity

If crude mechanical selection systems are used, then device complexity is reduced, but productivity deteriorates due to increased human error and selection inefficiency

Engineering Contradiction:
Improvepurchasing efficiencyVSAvoidselection interface complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent replaces mechanical selection systems with an electronic touch-sensitive interface that automatically processes selection inputs. This substitution eliminates manual manipulation of mechanical components and reduces human error by providing a more precise and reliable method of product selection, thereby improving purchasing efficiency despite increased electronic system complexity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Vending machines, automated retail stores, and retail displays with a computer controlled, activation system that senses either the gesture of a customer proximate product display tubes or a touch-screen selection on a computer screen. Item-based lighting produces variable visual effects in conjunction with actual or potential vends to provide an enhanced vending experience. Offered products are stored within display tubes that are arranged in orderly geometric arrays. RGB lighting through a plurality of LED banks associated with each display tube are controlled by the activation system Combinations of differently colored LED's are computer controlled on a per product basis to artistically illuminate available products and assist customers. Pre-programmed lighting sequences can switch LEDs off and on, vary their intensity, and alter resultant colors.
