Solution Overview

Problem

Existing systems are inefficient and inconvenient for end users to return items to service providers due to varying return procedures and requirements, leading to failed refunds and unnecessary deliveries.

Innovation Solution

A server computer system that facilitates item returns by coordinating with transporters to ensure items meet service provider criteria, using machine-readable codes and customizable return procedures, enabling seamless integration of returns with deliveries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional return systems are used, then service providers can receive returned items, but the process is inefficient and inconvenient for end users due to varying return procedures and requirements

Engineering Contradiction:
Improveconvenience of item return processVSAvoidcomplexity of return procedures
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a courier service as an intermediary between the end user and service provider. The courier collects the returned item from the user, transports it to the service provider, and handles the refund process. This intermediary absorbs the complexity of varying return procedures, presenting a simple, unified interface to the end user while managing diverse service provider requirements in the background.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The courier service performs multiple functions: collecting items from users, transporting them to service providers, verifying item conditions, processing refunds, and coordinating with both users and providers. This multi-functional approach consolidates what would otherwise be separate, complex procedures into a single universal service that handles all return operations regardless of service provider-specific requirements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If traditional return systems are used, then items can be returned to service providers, but failed refunds and unnecessary deliveries occur

Engineering Contradiction:
Improvesuccess rate of refundsVSAvoidunnecessary deliveries
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The courier verifies the item's condition and authenticity before transporting it to the service provider. This preliminary verification ensures that only eligible items are returned, preventing failed refunds and unnecessary deliveries. The courier checks whether the item matches the return request details and confirms it meets the service provider's acceptance criteria before initiating the return process.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If a centralized return system is used, then returns can be processed, but delivery routes are not optimized and efficiency is reduced

Engineering Contradiction:
Improveefficiency of return processingVSAvoidtime for deliveries
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent combines return deliveries with regular delivery routes by integrating the courier service into the existing delivery network. Couriers who are already traveling to deliver items to users can collect return items on the same route, and items being returned can be consolidated with outbound deliveries. This merging of functions optimizes routes, reduces travel time, and increases overall system productivity without sacrificing return processing efficiency.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A method includes receiving, by a server computer, request from an end user of an item to deliver the item to a service provider. The method includes providing, by the server computer, a retrieval message to a transporter to travel to the end user to retrieve the item and determine if the item is suitable for return to the service provider, and receiving, by the server computer, an item confirmation message from the transporter that the item is suitable for return to the service provider.
