Innovation Solution
An inkjet recording device equipped with an operating state acquisition unit, display unit, and code generation unit that allows users to generate a two-dimensional code encoding predefined parameter values, enabling easy data capture and transmission without complex operations, while maintaining security through network-free communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct USB or network connection is used to acquire internal data, then ease of operation is improved, but security is compromised
Solution Approach 1:
The patent introduces a camera as an intermediary device to capture the display screen showing internal data, and a smartphone as a second intermediary to receive and process the captured image. This mediator chain enables data acquisition without direct connection, thus maintaining security while improving ease of operation.
Solution Approach 2:
The patent replaces the mechanical/electrical connection system (USB or network cables) with an optical system (camera capturing display screen). This substitution eliminates the need for physical connections that compromise security, while still enabling efficient data acquisition through image capture and recognition.
2Reliability
If complicated operations are required to acquire internal data, then security is maintained, but ease of operation deteriorates
Solution Approach 1:
The display screen acts as a visual intermediary that presents internal data in an easily captureable format, while the camera serves as an operational intermediary that simplifies the data extraction process. This eliminates complicated operations while maintaining security through indirect acquisition.
Solution Approach 2:
The patent creates a visual copy of the internal data through the display screen, which can then be captured by the camera. This copying mechanism allows users to obtain data without complex operations, while the original data remains securely within the device.
3Productivity
If USB memory or external network connection is used, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent uses the display screen and camera as intermediaries to bridge the device and the user's smartphone. This intermediary approach enables efficient data transfer without requiring the device to have USB memory or network connectivity, thus improving productivity while avoiding increased device complexity.
Solution Approach 2:
The patent extracts the data acquisition function from the device itself and relocates it to the user's smartphone. The device only needs to display the data, while the smartphone handles the capture, storage, and processing. This extraction improves productivity without adding complexity to the device.

AI summary
Internal data contributing to trouble resolving is easily acquired, and usability is improved. An inkjet recording device includes an operating state acquisition unit that acquires parameter values indicating an operating state of the inkjet recording device, which includes at least one a pressurization state, a charge state, a deflection state, and a recovery state, a display unit that displays a reception screen for receiving a command to generate a two-dimensional code from a user, and a code generation unit that generates the two-dimensional code by encoding a parameter value constituting a parameter set of a predefined type among the parameter values acquired by the operating state acquisition unit when the generation command is received via the reception screen of the display unit. The display unit is configured to display the two-dimensional code generated by the code generation unit.
