Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional self-checkout systems are costly and occupy significant space, limiting retailers' and customers' options for checkout processes.
Innovation Solution
A transaction system and method utilizing a server, mobile communication device, and checkout system, where the server connects with the mobile device to receive item descriptions and prices, processes payments, and provides digital or printed receipts, offering a more flexible and space-efficient alternative to traditional checkout systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional self-checkout systems are deployed, then automated transaction processing is achieved, but system cost and space occupation increase significantly
Solution Approach 1:
The patent uses mobile communication devices (smartphones, tablets) as portable replicas of traditional checkout terminals. The server creates digital copies of transaction interfaces, item databases, and payment processing capabilities on customers' personal devices, eliminating the need for physical checkout counters and reducing space requirements while maintaining automated transaction functionality
Solution Approach 2:
The patent replaces physical mechanical checkout infrastructure (counters, scanners, card readers) with wireless electronic communication. Transaction data, item information, and payment processing are transmitted electronically between the mobile device and server, substituting mechanical systems with electronic/digital systems that require minimal physical space
2Extent of automation
If traditional self-checkout systems are deployed, then automated transaction processing is achieved, but system cost increases
Solution Approach 1:
The patent makes the server system universal by serving multiple functions: it acts as the central database, transaction processor, payment gateway, and communication hub. This multi-functional design eliminates the need for separate specialized hardware for each function, reducing overall system cost while maintaining automated transaction processing
Solution Approach 2:
By copying transaction interfaces and functionality to customers' existing mobile devices, the system avoids the cost of providing dedicated checkout hardware to each customer. The server replicates necessary functions digitally, leveraging customers' existing devices to reduce infrastructure investment
3Area of stationary object
If mobile communication devices are used for transactions, then space efficiency is improved, but device complexity increases
Solution Approach 1:
The server acts as an intermediary that manages the complexity of transaction processing, database queries, and payment operations. By centralizing complex functions on the server side and presenting simplified interfaces on mobile devices, the system reduces the complexity burden on customer devices while maintaining space efficiency
Data Source
AI summary
A transaction system and method in which a customer operates a mobile device, such as a smart phone, to interact with a transaction server during a transaction at a checkout station while scanning items. An example method includes establishing by the server a connection with a mobile communication device, receiving by the server item descriptions associated with items purchased from a code reader, sending by the server prices of the items and the item descriptions to the mobile communication device for display by the mobile communication device, and receiving payment by the server from the customer for the items.
