Solution Overview

Problem

Existing methods for transitioning from a sample to a full version of digital content, such as e-books, disrupt the user's experience by requiring them to exit the content, manage separate versions, and can be inconvenient due to slow network connections.

Innovation Solution

A seamless transition system that integrates a 'buy' page within the sample content, allowing users to purchase the full version without leaving the reading experience, with the full version being downloaded in the background, ensuring uninterrupted reading and automatic synchronization of the reading position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the user exits the content to purchase the full version, then the purchase transaction can be completed, but the user's reading experience is interrupted

Engineering Contradiction:
Improvepurchase convenienceVSAvoidreading interruption
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system initiates the download of the full version content in advance while the user is still reading the sample. A buy page is inserted into the sample content at a predetermined location, allowing the user to trigger the purchase and download process without leaving the reading interface. The download begins automatically or upon user confirmation, so that when the purchase is complete, the content is already available for immediate seamless transition.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces a buy page as an intermediary element within the sample content. This buy page serves as a bridge between the sample reading experience and the full version purchase process. When the user encounters the buy page during reading, they can initiate the purchase without exiting the content. The buy page mediates the transition by providing purchase options and triggering the download process while keeping the user within the reading interface.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the device treats the full version as separate from the sample version, then the purchase transaction is simplified, but the user's library becomes cluttered with both versions

Engineering Contradiction:
Improvecontent managementVSAvoidlibrary clutter
Core Design Contradiction:
Device complexityVSQuantity of substance

Solution Approach 1:

The system merges the sample version and full version by establishing a parent-child relationship between them. The sample is treated as a reference to the full version rather than a completely separate entity. When the user purchases the full version, the system detects the existing sample and automatically replaces it with the full version, or integrates the full version while maintaining the same library entry. This merging approach prevents library clutter by ensuring that only one version (the full version after purchase) remains in the user's library.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system automatically discards the sample version once the full version is purchased and downloaded. The buy page or system logic monitors the purchase status and, upon successful completion, removes or replaces the sample content with the full version. This automatic discarding prevents the accumulation of multiple versions in the user's library, maintaining organization without requiring manual intervention.

Inventive Principle:
Principle #34Discarding and recovering

3Ease of operation

If the user manually opens the full version and navigates to the reading position, then the full version can be accessed, but the transition process becomes complex and time-consuming

Engineering Contradiction:
Improvecontent accessVSAvoidtransition time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by automatically tracking the user's reading position within the sample content. When the purchase is initiated, the system records the current page or position and uses this information to automatically navigate to the corresponding location in the full version after download completes. This eliminates the need for the user to manually navigate, as the system has already prepared the navigation path in advance.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms to monitor the user's reading progress and adjust the transition process accordingly. The buy page or system logic continuously tracks the user's position in the sample and uses this feedback to determine when and how to initiate the download and transition. After the full version is downloaded, the system uses the accumulated feedback about reading position to automatically open the full version at the correct location, creating a seamless transition without manual intervention.

Inventive Principle:
Principle #23Feedback

4Reliability

If the user waits to purchase the full version due to slow network connection, then network reliability is considered, but the overall process time increases

Engineering Contradiction:
Improvenetwork dependencyVSAvoidpurchase waiting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system initiates the download of the full version content as soon as the user expresses interest through the buy page, rather than waiting for the purchase to fully complete or for network conditions to be optimal. By starting the download in advance during the purchase process, the system makes use of any available network bandwidth and prepares the content for immediate access once the transaction is finalized. This preliminary download action reduces the overall waiting time while maintaining reliability through progressive download and validation.

Inventive Principle:
Principle #10Preliminary action

AI summary

A client (e.g., an eReader) receives and displays a sample version of content to a user retrieved from a store server. The sample version is a subset of the full version of the content. The client determines a location in the sample content in which to insert a buy page that allows the user to purchase the full version. The buy page may be inserted at a location that minimizes the time the user spends waiting for the full version to be installed on the client. The client uses one or more locating factors to determine the location. The user may interact with the buy page inserted at the determined location to purchase the full version of the content. The client interacts with the store server to conduct the purchase transaction, and seamlessly transitions the user from the sample to the full version of the content.
