Humidity-Based Data Transfer for Devices Without User Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices without user interfaces, such as keyboards or touchscreens, face challenges in receiving data symbols, particularly network credentials, which are typically entered manually, making it inconvenient or impossible to connect to networks.
Innovation Solution
The method involves controlling humidity levels around a device to represent different data symbols, using household appliances like washing machines or ovens with humidity sensors to alter and measure humidity, converting these levels into binary format for data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input methods (keyboard, touchscreen) are used for data entry, then data symbols can be entered accurately, but devices without user interfaces cannot receive data
Solution Approach 1:
The patent introduces humidity as an intermediary medium to transfer data between devices. A transmitter device alters humidity levels to encode data symbols, which are then detected by a receiver device through its humidity sensor. This intermediary approach enables data communication between devices without requiring direct manual input or traditional interfaces.
Solution Approach 2:
The patent replaces mechanical input methods (keyboard, touchscreen) with a environmental parameter-based system. Instead of requiring physical interaction with mechanical interfaces, the system uses humidity level changes to represent and transmit data symbols, enabling devices without mechanical interfaces to receive data.
2Ease of operation
If modulated light is used for data input, then data can be transmitted wirelessly, but it may not always be possible or convenient
Solution Approach 1:
The patent uses changes in humidity parameter to encode and transmit data symbols. By varying humidity levels (e.g., high/low, dry/humid) to represent different data values, the system enables wireless data transmission that is more universally applicable than light-based methods, working in environments where light transmission may be impractical.
3Adaptability or versatility
If humidity levels are used to represent data symbols, then devices without user interfaces can receive data, but the method requires precise humidity control and measurement
Solution Approach 1:
The transmitter device performs preliminary actions to alter humidity levels before data detection. By proactively creating distinct humidity states (e.g., drying the environment, adding moisture) to represent data symbols, the system ensures that the humidity changes are sufficient for reliable detection by the receiver's humidity sensor, thereby reducing the precision requirements.

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.
