Solution Overview

Problem

Users face challenges in effectively tracking and comparing multiple alternatives during the purchasing decision process, often leading to non-optimal choices due to information overload and lack of structured methods for maintaining and comparing research information.

Innovation Solution

A research note system that detects user intent to compare items by analyzing browse history and search queries, allowing users to create and share structured research notes, which include selected items, comparison factors, and priority information, and provides social features for feedback and collaboration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manually track and compare multiple alternatives using crude notes or spreadsheets, then they can maintain some level of organization, but the complexity of managing and comparing research information increases significantly

Engineering Contradiction:

Improveease of tracking and comparing alternativesVSAvoidcomplexity of managing research information

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a computer-based research note system as an intermediary between users and their research information. This system automatically captures user activity data, generates structured research notes, and presents organized comparisons, thereby reducing the complexity of managing research information while improving ease of operation.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs self-service by automatically detecting user intent to compare items, gathering relevant information, and creating structured research notes without requiring manual intervention. This automation reduces the operational burden on users while maintaining comprehensive research tracking.

Inventive Principle:

Principle #25Self-service

2Loss of information

If users gather extensive information about multiple alternatives, then they can make more informed decisions, but information overload occurs making it difficult to process and compare

Engineering Contradiction:

Improvecompleteness of research informationVSAvoidease of processing and comparing information

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent segments research information into structured research notes with distinct components including compared items, comparison factors, and priority indicators. This segmentation organizes extensive information into manageable units, reducing information overload while preserving completeness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system applies local quality by allowing users to assign different priorities to different comparison factors within each research note. This enables selective emphasis on important information while de-emphasizing less critical details, making information processing more efficient without losing completeness.

Inventive Principle:

Principle #3Local quality

3Productivity

If users mentally store and compare information about alternatives, then they can quickly access stored information, but the complexity of maintaining accurate comparisons increases and errors occur

Engineering Contradiction:

Improvespeed of accessing research informationVSAvoidaccuracy of comparison information

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent creates structured digital copies of research information in standardized formats. These copies are automatically generated from user activity data and maintain consistent structures, enabling quick access while ensuring accuracy through systematic data capture and storage.

Inventive Principle:

Principle #26Copying

4Reliability

If the system exposes research note data to other users, then social feedback and collaboration improve decision quality, but the complexity of managing and sharing data increases

Engineering Contradiction:

Improvequality of purchasing decisionsVSAvoidcomplexity of data management and sharing

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a universal research note data structure that serves multiple functions: storing user-specific research information, enabling social feedback mechanisms, and supporting data mining operations. This multi-functionality reduces the need for separate systems while improving decision quality through social interaction.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Comparative decision systems and methods are disclosed for gathering and mining data representative of purchase decisions. One disclosed comparative decision system detects when a user is comparing items and provides the user with the ability to create a research note storing comparative information for the alternative items. The system displays information about items according to a variety of factors. The user can customize the factors and enter information for each alternative item according to the various factors. Some information may be pre-populated by the system. The research note may be made visible to other users, and may be suggested to another user based on the note's expected helpfulness and relevance to that user. One disclosed method for mining data stored within research notes identifies which factors are given higher relative priorities by users considering a purchase. Another mining method analyzes the effects of price changes on item popularity.
