Solution Overview
Problem
IoT devices without input/output apparatuses face challenges in setting up Internet connections, particularly with wireless LAN setups, as they often lack buttons for schemes like Wi-Fi Protected Setup (WPS) required for easy connection to routers.
Innovation Solution
A communication apparatus and method that uses a first device to temporarily operate as an access point, generating a code sequence based on a shared initial value to extract and segment network identification and authentication information, allowing the IoT device to connect to a router without physical input/output apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Wi-Fi Protected Setup (WPS) with Push Button Configuration is used for wireless connection setup, then the ease of operation is improved, but the device complexity increases due to requiring physical buttons on both access point and terminal
Solution Approach 1:
The patent extracts the button-pressing action from the IoT device by implementing a tactile sensor that detects touch input on its housing surface. This allows the IoT device to participate in WPS Push Button Configuration without requiring a dedicated physical button, thereby reducing device complexity while maintaining ease of operation for wireless connection setup
Solution Approach 2:
The housing of the IoT device serves multiple functions: it acts as both the structural enclosure and the touch-sensitive input surface. By making the housing itself responsive to tactile input, the device eliminates the need for separate input apparatus while maintaining the push-button configuration capability, thus reducing overall device complexity
2Ease of operation
If IoT devices are equipped with dedicated buttons for WPS, then the ease of operation is improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The patent merges the housing structure with the input function by implementing a tactile sensor that detects touch on the housing surface. This combination eliminates the need for separate buttons and their associated mounting hardware, simplifying the manufacturing process and reducing assembly complexity while maintaining ease of operation for connection setup
Solution Approach 2:
The housing serves dual purposes as both structural enclosure and input device. By making the housing itself responsive to tactile input through integrated sensors, the device reduces component count and manufacturing complexity while maintaining user-friendly connection setup capability
3Device complexity
If traditional wireless LAN setup methods are used requiring manual input, then device complexity is reduced, but the ease of operation deteriorates due to lack of input apparatus
Solution Approach 1:
The patent introduces a tactile sensor as an intermediary between the user and the IoT device system. This sensor detects touch input on the housing and translates it into connection setup actions, enabling users to perform WPS configuration without direct manual input to the device, thus improving ease of operation while keeping the device structure simple
Solution Approach 2:
The IoT device enables users to perform connection setup by touching the housing, which the tactile sensor automatically detects and processes. This self-service mechanism allows the device to interpret user intent through simple tactile input and autonomously execute the connection setup process, improving ease of operation without adding complex input apparatus

AI summary
A communication apparatus for connecting to the Internet without using an input/output apparatus is provided. The communication apparatus includes: a first connecting unit configured to connect to a first device; an acquiring unit configured to acquire, via the first device, setup information for connecting to a second device that operates as a router; and a second connecting unit configured to connect to the second device based on the setup information. A code sequence is generated using a code generator that is in common with the first device from an initial value that is shared with the first device. In addition, network identification information extracted from a signal received from the first device is searched for in the code sequence, and network authentication information is segmented from a predetermined offset position using a matching location as a reference.
