Solution Overview

Problem

Current point of sale (POS) systems require manual coding and editing by specialized personnel, leading to errors, inefficiencies, and outdated screens due to the complexity of the process, which discourages frequent updates.

Innovation Solution

A web-based POS builder system that allows non-expert operators to assemble and edit POS systems in real-time over the internet, using a web server and local or remote workstations, enabling real-time testing and iteration of screen designs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual coding and editing by specialized personnel is used, then POS screens can be created, but the process is time-consuming and error-prone

Engineering Contradiction:

Improveaccuracy of POS screenVSAvoiddevelopment time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The system enables non-expert operators to build and edit POS screens themselves through a web-based interface, eliminating the need for specialized personnel. The drag-and-drop functionality and automated code generation allow business users to create accurate screens independently, resolving the contradiction between accuracy and time consumption.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

A web-based builder interface acts as an intermediary between the user and the POS screen generation process. This intermediary provides a simplified, intuitive interface that translates user actions into properly coded screens, eliminating the need for users to directly write complex code while maintaining accuracy.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of manufacture

If manual POS screen building is used, then screens can be created, but the process is complex and requires specialized training

Engineering Contradiction:

Improveease of POS screen creationVSAvoidcomplexity of interface

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The system empowers non-expert users to create POS screens through an intuitive web interface with drag-and-drop functionality. Users can assemble screens by simply dragging elements to desired positions without needing to understand underlying code or complex interface requirements, dramatically improving ease of manufacture.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system replaces complex manual coding processes with automated web-based interface operations. Instead of requiring users to manually write and debug code through complex programming interfaces, the system uses web technologies and automated generation to simplify the creation process.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If POS screen changes are made manually, then updates can be made, but errors increase and updates are avoided

Engineering Contradiction:

Improveability to update screensVSAvoidreliability of POS screen

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system enables operators to make screen updates themselves through the web interface, increasing adaptability. Because the interface is designed to prevent errors and automatically generates clean code, updates can be made frequently without compromising reliability, resolving the contradiction between adaptability and reliability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system provides immediate feedback during the screen building process, allowing users to test and validate their changes before deployment. This feedback mechanism ensures that updates are error-free, maintaining reliability while enabling frequent adaptations.

Inventive Principle:

Principle #23Feedback

4Productivity

If off-line POS screen editing is used, then screens can be edited, but testing is delayed and iterations are slow

Engineering Contradiction:

Improvespeed of screen iterationVSAvoidtime to test and iterate

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The web-based system allows continuous iteration and testing of POS screens without interruption. Users can make changes, test them immediately in the browser, and refine their designs in real-time, eliminating the delays associated with offline editing and batch testing processes.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The system allows users to perform preliminary testing and validation of screen designs before final deployment. By enabling immediate testing in the web interface, users can identify and correct issues early in the design process, reducing the need for later iterations and accelerating overall productivity.

Inventive Principle:

Principle #10Preliminary action
