Solution Overview

Problem

Existing online purchasing systems struggle to provide relevant recommendations to users during their purchase decision-making process, often distracting or frustrating customers with redundant or irrelevant information, and fail to effectively address shopping cart abandonment.

Innovation Solution

Implementing facet-based context-aware user interfaces that utilize algorithms to infer user intent through search behavior and product interactions, providing personalized product recommendations and alternatives that align with the user's intent context, especially during critical moments of potential abandonment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional online purchasing systems provide general product recommendations, then users receive information about multiple brands and products, but users experience distraction and frustration due to redundant or irrelevant information

Engineering Contradiction:
Improverecommendation relevanceVSAvoiduser distraction and frustration
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system continuously monitors user interactions (clicks, time spent, additions to cart) and uses this feedback to refine and update product recommendations in real-time, ensuring recommendations remain relevant and reduce user distraction

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts recommendation parameters based on user behavior patterns, changing the weighting of different product attributes and filtering criteria to optimize recommendation relevance for each user's specific context

Inventive Principle:
Principle #35Parameter changes

2Loss of information

If users explore multiple brands and products during purchase decision, then users conduct thorough research, but the exploration process becomes time-consuming and circular rather than linear

Engineering Contradiction:
Improvepurchase decision informationVSAvoidexploration time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The system pre-organizes product information and comparisons based on likely user needs, presenting curated selections that reduce the need for extensive circular exploration while maintaining comprehensive information availability

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system acts as an intermediary that synthesizes information from multiple products and brands, presenting consolidated comparisons and insights that help users make informed decisions without manually exploring each product in detail

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of information

If systems provide redundant information to assist customers, then customers receive comprehensive product details, but the redundant information may be unhelpful or harmful by distracting or frustrating users

Engineering Contradiction:
Improveproduct information completenessVSAvoiddecision-making ease
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The system extracts and prioritizes only the most relevant product information and comparisons for each user based on their demonstrated interests and behavior, removing redundant details that would distract or frustrate users while maintaining essential information completeness

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

Systems, devices, and methods are provided for facet-based context-aware user interfaces. A system such as an online purchasing system may determine one or more intent contexts based at least in part on one or more user interactions with an online purchasing system associated with a first product. A list of substitute products may be determined based on the intent context and facets associated with the substitute products to provide for a diversity of dimensions along which a user can explore different products.
