Sensor-Based Network Device Configuration via Optical Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for configuring and controlling smart appliances in home networks are cumbersome, requiring manual input of static PINs or push buttons, which are user-unfriendly, prone to errors, and vulnerable to security issues, and often require appliances to be constantly active, leading to increased power consumption.
Innovation Solution
A mobile device with sensors, such as cameras or microphones, decodes configuration information from smart appliances using QR codes, Li-Fi, or audio signals to securely connect them to a network, reducing manual intervention and enhancing security and power efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input of static PINs or push buttons is used for configuring smart appliances, then configuration can be achieved, but the process becomes cumbersome, user-unfriendly, and prone to errors
Solution Approach 1:
The patent replaces manual mechanical input methods (push buttons, keyboard entry) with optical sensing technology. The sensor detects configuration information optically transmitted by the smart appliance, eliminating the need for manual PIN entry or button pressing. This substitution of mechanical interaction with optical detection resolves the contradiction by making the process easier to operate while reducing manual intervention complexity.
Solution Approach 2:
The patent introduces an optical signal as an intermediary between the smart appliance and the sensor. Instead of direct manual input or electrical connection, configuration information is transmitted through optical signals (visible light or infrared) that the sensor detects. This intermediary mechanism simplifies the configuration process by providing a natural, contactless interface that requires minimal user effort.
2Ease of operation
If appliances are kept constantly active for configuration, then configuration can be performed, but power consumption increases
Solution Approach 1:
The patent employs periodic action by transmitting configuration information through optical signals only when needed during the configuration phase. The smart appliance can remain in a low-power state and activate optical transmission briefly when a sensor is nearby or when configuration is requested. This periodic activation rather than continuous operation resolves the contradiction by maintaining configuration availability while significantly reducing power consumption.
Solution Approach 2:
The patent applies preliminary action by pre-configuring the optical transmission capability in the smart appliance design, but the actual transmission occurs only when configuration is needed. The system prepares the optical signaling mechanism in advance, but activates it selectively rather than continuously, allowing the appliance to remain energy-efficient while still being configurable when required.
3Reliability
If traditional configuration methods are used, then connectivity can be established, but security vulnerabilities arise
Solution Approach 1:
The patent replaces traditional electrical or wireless protocol-based configuration methods with optical sensing. By using optical signals for configuration information transmission, the system creates a more secure channel that is harder to intercept or spoof compared to traditional wireless communications. This substitution maintains reliable connection establishment while reducing security vulnerabilities associated with traditional methods.
4Ease of operation
If sensor-based decoding is implemented, then configuration information can be obtained, but additional hardware components are required
Solution Approach 1:
The patent applies universality by using a sensor that can serve multiple functions: detecting optical configuration signals, identifying the smart appliance type, and potentially tracking configuration status. This multi-functional approach reduces the need for separate dedicated components for each function, thereby minimizing the increase in device complexity while maintaining ease of operation benefits.
