Solution Overview

Problem

Existing electronic commerce product return and replacement systems face issues such as consumer inconvenience, increased costs, personal information leakage, and inefficient logistics due to complex operations and high rates of return/replacement, particularly in home-delivery and store-based models.

Innovation Solution

A product return/replacement system utilizing a product return/replacement device with a computer, printer, and QR code reader, integrated with a product return/replacement server, allows consumers to return or replace products by scanning a QR code, generating a delivery code, and using a logistics network for efficient product collection and delivery, minimizing personal information exposure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If home-delivery operator collects product from consumer home, then product return is convenient for consumer, but consumer personal information may leak and consumer must wait at home

Engineering Contradiction:
Improveconvenience of product returnVSAvoidpersonal information leakage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a store as an intermediary between the consumer and home-delivery operator. The consumer deposits the product at the store, and the store forwards it to the operator. This intermediary structure allows the consumer to avoid being at home during collection, reducing personal information exposure while maintaining return convenience.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If home-delivery operator collects product from consumer home, then product return is convenient for consumer, but consumer must wait at home

Engineering Contradiction:
Improveconvenience of product returnVSAvoidwaiting time at home
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The consumer can independently deposit the product at the store without requiring the home-delivery operator to visit their home. This self-service approach at the store eliminates the need for the consumer to wait at home, allowing them to complete the return process at their convenience while the store handles the forwarding to the operator.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If store delivers product to EC operator, then product return flow is established, but work of salesclerk becomes complicated and operation time increases

Engineering Contradiction:
Improveproduct return flow capabilityVSAvoidoperation complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the return process into distinct segments: the consumer deposits the product at the store, and the store's logistics system automatically forwards it to the EC operator. This segmentation separates the consumer interaction (simple deposit) from the logistics coordination (automated forwarding), reducing the complexity of salesclerk operations while maintaining return flow capability.

Inventive Principle:
Principle #1Segmentation

4Productivity

If separate logistics for product return is used, then product return is achieved, but cost increases due to inefficient truck operation

Engineering Contradiction:
Improveproduct return processingVSAvoidlogistics cost
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent merges the product return logistics with the store's existing delivery logistics. The store uses its existing trucks and routes to forward returned products to the EC operator, combining multiple functions (product delivery and return collection) into a single logistics system. This eliminates the need for separate return logistics, reducing costs while maintaining processing efficiency.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A product return/replacement system is provided with which a consumer can return/replace products using a simple method. A product return/replacement device for performing return/replacement of products, the device comprising a computer and a printer. The computer is equipped with: a read unit that reads a return/replacement reception code that indicates that the consumer has made a return/replacement reservation; a communication unit that transmits the return/replacement code read by the read unit to an external return/replacement server, and receives from the return/replacement server a delivery code for managing the delivery status of the product; and a processor for causing the printer to print a label displaying the delivery code transmitted from the return/replacement serve. The consumer can affix the printed label to the product for return/replacement, and when the read unit has read the delivery code displayed on the label affixed to the product, the communication unit transmits the delivery code read by the read unit to the external return/replacement server.
