Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User devices such as smartphones and tablets often lack the capability to receive certain types of wireless communications due to the absence of required hardware and software, necessitating an alternate means for receiving wireless digital communications.
Innovation Solution
A disposable wireless receiver device connected to a user device that can receive wireless transmissions, decode message codes, determine authorization status, and transmit messages based on a comparison between message and receiver codes, enabling secure and authorized communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If user devices are made as small as possible, then device size is reduced, but the capability to receive certain types of wireless communications is lost due to lack of required hardware
Solution Approach 1:
The system divides the communication capability into two separate components: a permanent receiver device with specialized hardware (photodetector, VLC receiver, etc.) and a user device with display capabilities. The receiver device can be detached and replaced, allowing the user device to gain different wireless communication capabilities without permanently increasing its size.
Solution Approach 2:
The receiver device acts as an intermediary between the wireless transmission source and the user device. It receives wireless signals (VLC, Bluetooth, Wi-Fi), decodes them, and transmits the decoded messages to the user device for display, enabling the user device to access communication types it cannot directly receive.
2Adaptability or versatility
If specialized hardware is added to user devices to receive specific wireless communications, then communication capability is improved, but device complexity increases
Solution Approach 1:
The system separates the complex reception hardware from the user device and places it in an external receiver device. This allows the user device to maintain simplicity while still accessing specialized communication capabilities through the connected receiver device with its photodetector, VLC receiver, and other specialized components.
Solution Approach 2:
The receiver device is designed to handle multiple types of wireless communications (VLC, Bluetooth, Wi-Fi) through a single multi-functional unit. This provides the user device with access to various communication protocols without requiring separate hardware for each protocol, thereby reducing overall complexity.
3Reliability
If authorization verification is implemented through code comparison, then security is improved, but processing time increases
Solution Approach 1:
The receiver device performs authorization verification by comparing message codes with stored receiver codes before decoding and displaying messages. This preliminary security check ensures that only authorized transmissions are processed, maintaining security while enabling rapid verification through efficient code comparison algorithms.
Data Source
AI summary
A wireless receiver can be connected to a user device, such as a smartphone or a tablet device. The wireless receiver can receive a wireless data communication from a wireless transmitter. The wireless data communication can include a message code that can be compared by the wireless receiver to a receiver code stored at the wireless receiver to determine whether the wireless transmitter was authorized to transmit the wireless data communication, and/or whether the wireless receiver is authorized to use the wireless data communication. The wireless receiver can then decode a message from the wireless data communication and transmit the message to the user device for viewing through an application.
