Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Collaborative filtering algorithms struggle to recommend new products and provide customized recommendations for individual users, as they primarily rely on popularity and user similarity, failing to account for unique user preferences and behaviors.

Innovation Solution

A smart apparatus that generates user profiles using information from smart devices, which are then transmitted to a server to recommend personalized products based on a recommendation algorithm, allowing for customized and individualized product suggestions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If collaborative filtering algorithm is used for product recommendation, then recommendation coverage is improved, but recommendation accuracy deteriorates

Engineering Contradiction:

Improverecommendation coverageVSAvoidrecommendation accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The patent segments the recommendation system into two distinct components: a collaborative filtering module that provides broad recommendation coverage by leveraging user similarity, and a user profile analysis module that delivers accurate personalized recommendations by analyzing individual user behaviors, preferences, and contextual data. This segmentation allows each module to specialize in its strength without compromising the other.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent merges collaborative filtering results with user profile analysis results to create a hybrid recommendation system. The server combines recommendations from both approaches, using collaborative filtering for discovering new products and user profile analysis for filtering and ranking recommendations based on individual user characteristics, thereby achieving both broad coverage and high accuracy.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If user profile information is transmitted to multiple servers, then service versatility is improved, but information security deteriorates

Engineering Contradiction:

Improveservice versatilityVSAvoidinformation security

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent implements dynamic authorization where the smart apparatus evaluates each application's authorization status in real-time before transmitting user profile information. The communication interface checks whether the application has proper authorization credentials and only transmits data to servers that have been verified as authorized, creating a dynamic security mechanism that adapts to each request rather than using static permission settings.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The smart apparatus acts as an intermediary between user profile data and external servers, controlling all data transmission through centralized authorization checks. The communication interface serves as a gatekeeper that verifies server authorization credentials and filters which servers can receive user profile information, preventing unauthorized access while allowing legitimate services to function.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The present disclosure describes a smart apparatus, comprising: determining if an application is authorized to use a user profile, when the application installed on the smart apparatus requests the user profile; and transmitting the user profile to the server corresponding to the application when the application is determined to have a user right.
