Method, apparatus and device for transferring and receiving data symbols
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices without user interfaces, such as keyboards or touchscreens, face challenges in transmitting and receiving data symbols, particularly network credentials, which is essential for connecting to networks, as conventional methods are not always feasible or convenient.
Innovation Solution
The method involves controlling humidity levels around the device to represent different data symbols, using household appliances like washing machines or dishwashers to alter humidity, which are detected by humidity sensors to convey digital information, allowing devices to connect to networks without manual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If modulated light is used to input data symbols, then data can be transmitted to devices, but it may not always be possible or convenient
Solution Approach 1:
The patent changes the physical parameter used for data transmission from light modulation to humidity control. By varying humidity levels (first level for first symbol, second level for second symbol), the system enables data transmission to devices without requiring light detection capabilities, thus improving adaptability while maintaining operational convenience
Solution Approach 2:
The patent replaces the optical detection system (light modulation and detection) with a humidity-based system. Household appliances use their existing humidity control mechanisms to encode data, and devices receive data through humidity sensing rather than light detection, making the system applicable to a broader range of devices
2Ease of operation
If manual input via keyboard or touchscreen is used, then data symbols can be entered, but devices without these interfaces cannot receive data
Solution Approach 1:
The patent introduces humidity as an intermediary medium for data transmission. Instead of requiring direct interaction with device interfaces, data is encoded into humidity patterns that the device can sense passively. This intermediary approach allows devices without keyboards or touchscreens to receive data symbols, resolving the contradiction between manual input capability and device compatibility
Solution Approach 2:
The system allows devices to automatically receive and process data symbols through environmental humidity sensing without requiring manual operation. The device passively detects humidity changes and interprets them as data, enabling self-service data reception for devices lacking user interfaces
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach enables devices to receive data symbols, including network credentials, without the need for manual input, making it convenient for devices without traditional interfaces to connect to networks, especially suitable for IoT devices.

AI summary
To transfer data symbols to a device (10), the humidity in the vicinity of the device (10) is controllably altered. The humidity is set at a first level so as to represent a first symbol and the humidity is set at a second level so as to represent a second symbol which is different from the first symbol. The device (10) is able to measure the humidity in the vicinity of the device (10) to determine the level of humidity and thereby whether the first symbol or the second symbol is being transferred.
