Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in efficiently providing users with location-specific object information without overburdening cellular networks and reducing power consumption, especially in crowded areas where multiple users seek similar information simultaneously.
Innovation Solution
A wireless communication system incorporating a near field communication (NFC) reference device that stores object reference data and images, allowing a mobile device with an NFC transceiver, image sensor, and controller to recognize and overlay relevant data onto a sensed image, reducing data traffic and power usage by leveraging proximity-based communication and image recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If mobile devices use cellular networks to access location-specific object information, then users can obtain comprehensive object data, but data traffic on cellular networks increases and power consumption increases
Solution Approach 1:
The system segments information retrieval into two parts: (1) using NFC for short-range, low-power communication to get object reference data and images when in proximity, and (2) using cellular networks only when necessary for additional information. This segmentation reduces overall data traffic and power consumption while maintaining information availability.
Solution Approach 2:
The system performs preliminary actions by caching object reference data and images in the mobile device's memory when obtained via NFC. This preliminary storage allows the device to access information locally without immediately consuming cellular network resources, thereby reducing real-time power consumption and data traffic.
2Loss of information
If mobile devices use cellular networks to access location-specific object information, then users can obtain comprehensive object data, but data traffic on cellular networks increases
Solution Approach 1:
The system segments information retrieval into two parts: (1) using NFC for short-range, low-power communication to get object reference data and images when in proximity, and (2) using cellular networks only when necessary for additional information. This segmentation reduces overall data traffic and power consumption while maintaining information availability.
Solution Approach 2:
The system creates a copy of object information (reference data and images) through NFC communication and stores it in the mobile device's memory. This copy allows the device to access information locally without immediately consuming cellular network resources, thereby reducing real-time data traffic.
3Loss of information
If multiple users in crowded areas simultaneously seek location-specific information, then information availability increases, but network bandwidth is consumed and power consumption increases
Solution Approach 1:
The system implements local quality by enabling each user to access object information through NFC when in proximity to the object, rather than requiring simultaneous cellular network access. This local interaction model reduces network bandwidth consumption and improves overall network efficiency in crowded areas while maintaining information availability for each user.
4Loss of information
If mobile devices continuously access object information via cellular network, then information is always available, but power consumption increases
Solution Approach 1:
The system performs preliminary actions by caching object reference data and images in the mobile device's memory when obtained via NFC. This preliminary storage allows the device to access information locally without immediately consuming cellular network resources, thereby reducing real-time power consumption and extending battery life.
Solution Approach 2:
The system enables self-service by allowing the mobile device to store and access object information from its own cached data, eliminating the need for continuous cellular network connections. This self-service capability maintains information availability while significantly reducing power consumption and extending battery life.

AI summary
A wireless communications system may include a near field communication (NFC) reference device configured to store object reference data for at least one object associated with a geographic location of the NFC device. The wireless communications system may also include a mobile wireless communications device that includes an NFC transceiver configured to communicate with the NFC device based upon proximity thereto, an image sensor, a display, and a controller. The controller may cooperate with the NFC transceiver, the image sensor, and the display. The controller may be configured to determine a sensed image from the image sensor. The controller may also be configured to select object reference data for the sensed image based upon communication with the NFC reference device, and display the object reference data and the sensed image on the display.
