Solution Overview

Problem

Existing merchant/customer interaction systems in physical store settings are limited, as they typically consist of separate kiosks for customers and POS devices for merchants, restricting interaction and functionality.

Innovation Solution

A rocker POS tablet system with a tablet computer and enclosure/stand that allows transition between merchant and customer orientations, enabling dual-use functionality with separate product information displays and payment capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate kiosks and POS devices are used for customers and merchants, then each user group has dedicated functionality, but the system complexity increases and interaction is limited

Engineering Contradiction:
Improvedual-use functionalityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The POS device is designed to perform both merchant-specific functions (processing payments, managing inventory) and customer-specific functions (browsing products, placing orders) through a unified interface that adapts to different user roles, eliminating the need for separate kiosk systems

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

Solution Approach 2:

The patent combines previously separate customer kiosk functionality and merchant POS functionality into a single integrated device, allowing both user groups to interact with the same system through role-based interfaces, thereby reducing system complexity while maintaining versatility

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If traditional POS devices are used, then payment processing is reliable, but customer engagement and interaction are limited

Engineering Contradiction:
Improvecustomer engagementVSAvoidpayment processing
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system introduces a communication interface that mediates between customer interactions and merchant operations, allowing customers to engage with the system through a user-friendly interface while ensuring that payment processing remains secure and reliable through established protocols

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If separate customer and merchant systems are used, then each system can be optimized for its specific function, but interaction efficiency decreases

Engineering Contradiction:
Improveinteraction efficiencyVSAvoidswitching time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The POS device employs dynamic interface switching that automatically adapts between merchant and customer modes based on user identification and context, eliminating manual switching procedures and reducing time loss while maintaining optimized functionality for each user type

Inventive Principle:
Principle #15Dynamics

AI summary

Systems and methods for providing merchant/customer interaction include determining that a tablet computer is in a merchant orientation, retrieving merchant product information according to a received instruction and merchant orientation information, and displaying a merchant screen on the tablet computer that includes the merchant product information according to the merchant orientation information. A change in the orientation of the tablet computer enclosure/stand is then detected from the merchant orientation to a customer orientation. In response, the merchant screen is transitioned on the tablet computer display to a customer screen as the tablet computer enclosure/stand changes orientations by moving the merchant screen and the customer screen linearly while in a stacked orientation. The customer screen includes the merchant product information displayed according to customer orientation information such that the merchant product information is displayed differently on the customer screen relative to the merchant screen.
