Solution Overview

Problem

Consumers often overspend or make inferior purchases on ecommerce sites due to lack of awareness of similar products available at lower prices or better suited to their needs on other sites.

Innovation Solution

A browser plug-in application that identifies and displays similar products from a second ecommerce site within the browser window of a first site, allowing users to view and purchase these products without opening multiple tabs, using a backend server to analyze product information and categorize products based on machine learning algorithms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If consumers purchase products on a single ecommerce site without checking other sites, then the purchasing process is simple and quick, but consumers may overspend or miss better product options

Engineering Contradiction:
Improveawareness of alternative productsVSAvoidtime to search and compare products
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-fetching and storing product information from multiple ecommerce sites in advance. When a consumer views a product on one site, the plug-in has already retrieved similar products from other sites, enabling immediate comparison without requiring the consumer to manually search multiple sites.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The plug-in acts as an intermediary between the consumer and multiple ecommerce sites. It automatically retrieves product information from other sites and presents it within the consumer's current browser window, mediating the comparison process without requiring the consumer to directly interact with multiple sites.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If consumers manually search multiple ecommerce sites for similar products, then they can find better prices and options, but the process becomes complex and time-consuming

Engineering Contradiction:
Improveawareness of alternative productsVSAvoidcomplexity of searching process
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system merges the functionality of multiple ecommerce site searches into a single integrated view. The plug-in combines product information from the current site and other sites into one unified display within the browser window, eliminating the need for consumers to manually navigate multiple sites and compare products separately.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system performs the search and comparison tasks automatically without requiring consumer intervention. The plug-in autonomously retrieves product information, identifies similar products, and presents comparisons, allowing the consumer to simply view and decide without performing any manual search operations.

Inventive Principle:
Principle #25Self-service

3Loss of information

If consumers open multiple browser tabs to compare products from different sites, then they can see alternative products, but memory and network demands increase

Engineering Contradiction:
Improveawareness of alternative productsVSAvoidmemory and network demands
Core Design Contradiction:
Loss of informationVSUse of energy by moving object

Solution Approach 1:

The system implements a nested structure where the plug-in embeds product information from other ecommerce sites within the consumer's current browser window. Instead of requiring separate browser tabs for each site, the plug-in nests the alternative product displays inside the existing browser interface, utilizing the same memory and network resources already allocated to the current tab.

Inventive Principle:
Principle #7Nested doll (Nesting)
