Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the surface modifying apparatus is arranged close to the stopped recording medium to execute surface modification processing, then the adhesive properties of the liquid are improved, but the recording medium degrades due to heat emission from the surface modifying apparatus
Solution Approach 1:
The surface modifying apparatus is designed with movable components that allow dynamic adjustment of the distance between the apparatus and the recording medium. During surface modification processing, the apparatus is positioned close to the recording medium to ensure effective treatment and improve liquid adhesive properties. After processing, the apparatus is moved away to prevent heat degradation of the recording medium during intermittent stop periods.
Solution Approach 2:
The surface modification processing is executed periodically only during the brief time intervals when the recording medium is actively passing through the processing position. The surface modifying apparatus operates in periodic cycles synchronized with the intermittent conveyance, activating during passage time and remaining inactive or separated during stop periods to avoid heat degradation.
2Manufacturing precision
If the recording medium is intermittently conveyed and stopped for image recording, then the image quality is improved, but the heat degradation becomes marked when the surface modifying apparatus is close to the stopped recording medium
Solution Approach 1:
The system dynamically adjusts the position of the surface modifying apparatus in synchronization with the intermittent conveyance cycle. During the stop phase when image recording occurs, the apparatus is separated from the recording medium to prevent heat degradation. During the conveyance phase, the apparatus is positioned close to execute surface modification processing, thereby maintaining image quality while avoiding heat damage.
Solution Approach 2:
The surface modification processing is executed as a preliminary action during the brief conveyance phase before the recording medium stops for image recording. This timing ensures that the recording medium receives necessary surface treatment while minimizing exposure time to heat, preventing degradation during the subsequent stop period when image quality is being recorded.
3Manufacturing precision
If the surface modifying apparatus emits heat during surface modification processing, then the surface treatment effectiveness is improved, but the recording medium degrades due to heat conduction
Solution Approach 1:
The harmful heat emission is extracted or separated from the useful surface modification function. The surface modifying apparatus is designed to emit heat only during the brief active processing window when the recording medium is moving through, and is physically separated or deactivated during stop periods. This extraction of the harmful thermal effect during non-processing times prevents heat conduction degradation while maintaining surface treatment effectiveness during active operation.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively suppresses recording medium degradation and ensures high-quality image recording by minimizing heat transfer from the surface modifying apparatus during the surface modification process.
Implementation Method 1
The surface modifying apparatus is configured and arranged to, during a passage time in which the recording medium passes through the processing position, execute surface modification processing on the recording medium passing through the processing position, and to emit heat along with execution of the surface modification process.

AI summary
An image recording device includes a support member, a recording head, a conveyor unit, a surface modifying apparatus and a movement mechanism. The conveyor unit intermittently conveys a recording medium toward a support member along a conveyance path, and intermittently passes the recording medium through a processing position disposed on an upstream side of the supporting member with respect to the conveyance path. The surface modifying apparatus, during a passage time in which the recording medium passes through the processing position, executes surface modification processing on the recording medium passing through the processing position, and emits heat along with execution of the surface modification process. The movement mechanism places the recording medium passing through the processing position near the surface modifying apparatus during the processing time, and separates the recording medium and the surface modifying apparatus when the passage time ends.
