Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current barcode scanning systems at point of sale and inventory management lack efficient wireless transmission and processing capabilities, limiting their functionality in transmitting and processing various types of data such as shipping addresses, payment information, and coupon codes.
Innovation Solution
A wireless communication device with a scanner that can transmit data wirelessly to an automated processing subsystem, enabling the identification and delivery of items, as well as processing coupon codes for discounts, using protocols like cellular or personal communications service, and integrating with systems for fulfillment and inventory management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If barcode scanners are tethered to host computer via cable, then data transmission reliability is improved, but device mobility and operational flexibility deteriorate
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The barcode scanner communicates with the host computer through wireless protocols (infrared, Bluetooth, WLAN) instead of physical cable connections, eliminating the trade-off between reliability and mobility while maintaining data transmission functionality.
2Ease of operation
If barcode scanners are integrated into portable data terminals, then device mobility is improved, but data transmission capability deteriorates
Solution Approach 1:
The patent makes the portable data terminal universally compatible with multiple communication protocols and host computer systems. The terminal can communicate via cable, infrared, Bluetooth, or WLAN connections, allowing it to function with various host computers without requiring specific physical or protocol compatibility, thus maintaining mobility while enhancing data transmission capability.
3Ease of operation
If wireless communication protocols are used for data transmission, then device mobility is improved, but transmission stability deteriorates
Solution Approach 1:
The patent implements feedback mechanisms in the wireless communication system where the host computer receives status information from the portable terminal and can request retransmission or confirmation of data packets. This feedback loop ensures stable and reliable data transmission over wireless connections by detecting and correcting potential transmission errors.
Data Source
AI summary
An interrogating and processing system and method is described. A wireless communication device interrogates an information source, having a barcode or tag, and wirelessly transmits data indicative of the information source. The interrogator can be built into or adjunct to the wireless communication device. An automated processing subsystem receives the transmitted data and identifies an item corresponding to the data. A fulfillment subsystem effects delivery of the item to a destination. There can be a coupon code scanning and processing system and method. A wireless computing device having an interrogator reads a coupon code. An automated processing subsystem receives the corresponding data and provides a benefit associated with the coupon. The benefit can be a discount on a product or service. Alternatively, at least a portion of the coupon including a code is displayed on a screen of the computing device for processing at a point of sale terminal.
