Image Recording Apparatus Motor Control for User Status Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience unease due to uncertainty about whether an image recording apparatus is operating based on their instructions or playing a melody during preprocessing, as the existing systems do not clearly communicate their operational status.
Innovation Solution
An image recording apparatus is designed with a controller that manages the operation of motors and mechanisms, including a feeding roller and driven mechanisms, to perform preparing operations and feeding operations based on received instructions, while also controlling a melody playback to inform the user of its status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the apparatus plays melody during preprocessing time, then user uneasiness is alleviated, but user confusion increases about whether the apparatus is operating based on instructions
Solution Approach 1:
The system provides feedback to the user through melody playback during preprocessing operations. The melody serves as an audible indicator that the apparatus is actively processing, giving the user confidence that the system is working while maintaining clear communication of operational status.
Solution Approach 2:
The melody acts as an intermediary signal between the preprocessing operation and the user. Instead of directly communicating technical processing states, the system uses melody as a mediating feedback mechanism that conveys operational status in a user-friendly manner.
2Loss of time
If the apparatus performs preparing operation in advance, then preprocessing time is shortened, but operational complexity increases with multiple motor control states
Solution Approach 1:
The system performs preliminary actions by executing the preparing operation in advance, before the actual recording operation begins. This allows the apparatus to complete necessary preparatory tasks ahead of time, reducing the overall processing time and improving efficiency.
Solution Approach 2:
The system dynamically adjusts motor control states based on the operational phase. During preprocessing, the first motor controls the feeding roller, while the second motor controls the driven mechanism. The controller transitions between these states seamlessly, managing complexity through dynamic state changes rather than static configuration.

AI summary
An image recording apparatus includes a first motor, a feeding roller, a second motor, a first driven mechanism, a recorder, and a controller. The feeding roller is configured to rotate by receiving driving force from the first motor. The first driven mechanism is configured to be driven by receiving driving force from the second motor. The controller is configured to: perform a preparing operation in response to receiving first information that instructs starting image recording by the recorder; perform a driving operation of driving the second motor to drive the first driven mechanism, in response to completing the preparing operation and not receiving second information including a recording condition and printing data; and in response to receiving the second information, stop the second motor and drive the first motor to perform a feeding operation by the feeding roller.
