Solution Overview

Problem

Consumers face difficulty in comparing and selecting gemstones due to their diverse attributes and unique characteristics, leading to an overwhelming purchasing process, as existing tools are inadequate in providing insightful recommendations.

Innovation Solution

A facilitated comparison system that uses a predictive model based on historical customer interaction data to calculate a selling index for gemstones, allowing users to compare gemstones with similar attributes and quality levels, displayed in a grid format for easy decision-making.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If consumers compare all possible gemstone attribute combinations, then they can make fully informed decisions, but the complexity and time required become overwhelming

Engineering Contradiction:

Improvecomprehensive attribute comparisonVSAvoidcomparison system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the overwhelming set of gemstone attributes into hierarchical groups (primary attributes like cut, color, clarity, carat weight, and secondary attributes). This segmentation allows consumers to focus on the most important attributes first, reducing the perceived complexity while maintaining comprehensive comparison capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system dynamically changes comparison parameters by allowing consumers to adjust attribute weights and importance levels. The facilitated comparison algorithm adapts the comparison criteria based on consumer preferences, transforming the fixed, overwhelming attribute list into a flexible, personalized comparison framework.

Inventive Principle:

Principle #35Parameter changes

2Loss of information

If the system provides detailed information on all gemstone attributes, then consumers can make informed decisions, but the information overload becomes confusing

Engineering Contradiction:

Improveinformation completenessVSAvoiddecision-making ease

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent applies local quality by providing detailed attribute information selectively based on consumer needs and preferences. Rather than uniformly presenting all attributes, the system highlights the most relevant attributes for each consumer's specific comparison context, making information both complete and manageable.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system implements partial action by initially presenting only the most critical attributes for comparison, then allowing consumers to drill down into additional details as needed. This staged information delivery prevents overwhelming consumers with all details at once while ensuring complete information is available when required.

Inventive Principle:

Principle #16Partial or excessive action

3Quantity of substance

If traditional comparison tools list all gemstone attributes, then all options are visible, but insightful recommendations cannot be provided

Engineering Contradiction:

Improvenumber of comparable optionsVSAvoidinsightful recommendations

Core Design Contradiction:

Quantity of substanceVSLoss of information

Solution Approach 1:

The facilitated comparison system incorporates feedback mechanisms where the algorithm learns from consumer interactions, attribute weightings, and comparison patterns. This feedback enables the system to provide increasingly personalized and insightful recommendations, transforming static attribute listing into a dynamic recommendation engine that understands consumer preferences.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent introduces an intelligent intermediary layer (the facilitated comparison algorithm) that sits between the raw gemstone data and the consumer. This intermediary processes the attribute data, applies consumer preferences, and generates insightful recommendations, bridging the gap between comprehensive data and actionable advice.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Reliability

If consumers evaluate each gemstone individually considering all attributes, then thorough evaluation is achieved, but the purchasing process becomes time-consuming

Engineering Contradiction:

Improveevaluation thoroughnessVSAvoidpurchasing process time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-calculating and storing attribute relationships, compatibility scores, and initial filtering results. When a consumer initiates a comparison, this pre-processed information is immediately available, eliminating the need for real-time computation of all attribute combinations and significantly reducing evaluation time while maintaining thoroughness.

Inventive Principle:

Principle #10Preliminary action

AI summary

Methods and systems are provided for facilitating comparison of gemstones having multiple attributes that characterize the gemstones. A facilitated comparison system receives from a user a selection of a gemstone in a collection of the gemstones. Each gemstone in the collection is associated with a selling index indicating a probability of the gemstone being bought by a customer. For each of a predetermined set of the attributes, the system determines one or more comparable ranges. The system identifies alternate gemstones to recommend using the comparable ranges for the attributes and the selling indices of the gemstones. The system displays to the user the selected gemstone and one or more of the alternate gemstones for comparison.
