Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users face difficulties in efficiently comparing and merging changes between different versions of presentation slide decks, particularly in retaining specific slides from original and modified decks, as existing systems require manual processes that are time-consuming and cumbersome.

Innovation Solution

A compare service that allows users to select and customize the type of changes to be detected between two slide decks, generating a comparison report and enabling the creation of a new slide deck with preferred slides, while allowing users to accept or reject individual changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual comparison and merging of slide decks is performed using traditional slide deck editing applications, then users can review and select changes between versions, but the process becomes time-consuming and cumbersome

Engineering Contradiction:

Improvedetection precision of changesVSAvoidtime for comparison process

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical operations in slide deck comparison with automated computational methods. The system automatically detects changes between slide deck versions by comparing slide elements, layouts, and content without requiring manual intervention, thus substituting the mechanical process of manual review with an automated digital comparison engine that provides precise change detection while significantly reducing time consumption

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a comparison service as an intermediary between the original and modified slide decks. This service acts as a mediator that automatically analyzes differences, generates change reports, and facilitates the merging process. The intermediary handles the complex comparison task, allowing users to focus on reviewing results rather than performing manual comparison operations

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If users manually create a new slide deck by copying individual slides from various versions, then they can retain selected slides, but the process becomes painstaking and complex

Engineering Contradiction:

Improveflexibility in slide selectionVSAvoidcomplexity of comparison process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent enables the comparison and merging process to serve itself automatically. The system autonomously identifies corresponding slides between versions, detects changes, and prepares merge options without requiring users to manually copy and paste slides. The self-service mechanism handles the complex matching and comparison logic, while users simply review and select preferred versions of each slide

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent segments the slide deck comparison process into discrete, manageable units. Each slide is analyzed individually as a separate element, allowing the system to detect changes at the slide level and provide granular control over which changes to accept. This segmentation enables flexible slide-by-slide review and selection while simplifying the overall complexity through structured, modular processing

Inventive Principle:

Principle #1Segmentation

3Loss of information

If traditional slide deck applications are used for comparison, then basic text changes can be reviewed, but other features specific to slide decks (slide master views, animation sequences, multimedia content) cannot be effectively compared

Engineering Contradiction:

Improvecompleteness of change detectionVSAvoidease of use for comparison

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent creates a universal comparison service that handles multiple types of slide deck elements through a single interface. The system is designed to detect and compare not only text content but also slide master views, animation sequences, multimedia content, and other presentation-specific features. This multi-functional approach consolidates various comparison capabilities into one unified tool that maintains ease of operation while comprehensively detecting all types of changes

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Disclosed herein are methods and systems for comparing two slide decks using a compare service. The compare service generates a comparison analysis for the two slide decks based on a comparison theme selected by the user. The result of the analysis is displayed in a comparison display that includes a slide selector section, a slide pair viewer section, and a navigable change summary section. In one embodiment, the compare service allows the user to select preferred slides from the two slide decks displayed in the comparison display, and subsequently generates a new slide deck that contains only the preferred slides selected by the user.
