Solution Overview

Problem

The process of online shopping can be time-consuming due to the need to navigate through various categories and read reviews, and users often interrupt their shopping sessions, leading to a loss of context and continuity.

Innovation Solution

An online session trace system that records and preserves the state of a user's shopping session, allowing them to resume from the exact point they left off, including attributes like mouse location, display device type, and geo-location for personalized notifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If users navigate through various categories and read reviews during online shopping, then they can find suitable products, but the shopping process becomes time-consuming

Engineering Contradiction:
Improveproduct selection accuracyVSAvoidshopping session duration
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system performs preliminary actions by automatically recording and preserving the user's shopping session state (including current category, viewed items, and selection criteria) before the user interrupts. When the user returns, the system has already prepared the restored session state, eliminating the need to重新 navigate through categories and reviews, thus maintaining product selection accuracy while reducing time loss.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If users interrupt their shopping sessions, then they can attend to other tasks, but they lose context and continuity of their shopping journey

Engineering Contradiction:
Improvesession resumption flexibilityVSAvoidshopping context
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The system creates a copy of the user's shopping session state (including current category, viewed items, cart contents, and selection criteria) and stores it on the server. When the user returns with a different device or after interruption, the system retrieves and restores this copied state, allowing the user to resume shopping with full context continuity across different sessions and devices.

Inventive Principle:
Principle #26Copying

3Productivity

If the system restores session state for returning users, then user efficiency improves, but system complexity increases

Engineering Contradiction:
Improveshopping session efficiencyVSAvoidsession trace system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system introduces a session trace module as an intermediary component that automatically records shopping state information and a session restoration module that retrieves and restores saved states. These intermediary modules handle the complexity of session management transparently, allowing users to benefit from restored context without directly interacting with the complex underlying mechanisms, thus improving efficiency while containing perceived system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

In various example embodiments, a system and method for enhancing a user's on-line experience by utilizing a computer-implemented on-line session trace system is provided. The on-line session trace system is provided in connection with an on-line trading platform. The on-line session trace system records and stores a state of an on-line session associated with a user identification and permits a user associated with the user identification to commence a further on-line session from a state corresponding to the saved state of a previous on-line session.
