Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drying devices face inefficiencies in evaporating moisture from recording media due to fixed positional relationships between light irradiation and air blowing components, leading to variable evaporation rates depending on their alignment.
Innovation Solution
A drying device that adjusts the distance between the light irradiation position and the air-blowing target position on a recording medium's movement route, allowing for optimal air flow and moisture evaporation by changing the air-blowing target position relative to the light irradiation position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the distance between light irradiation position and air-blowing target position is fixed, then the device structure is simple, but moisture evaporation efficiency varies and may be insufficient
Solution Approach 1:
The patent applies the dynamics principle by making the air-blowing target position adjustable relative to the light irradiation position. The air blowing part can change its target position along the recording medium movement route, transforming a static fixed-distance configuration into a dynamic adjustable one. This allows optimization of moisture evaporation efficiency by aligning air flow with highest temperature areas while maintaining structural feasibility through controlled adjustability rather than complete redesign.
2Productivity
If air is blown onto the recording medium at a fixed position downstream from light irradiation, then the device configuration is simple, but the amount of moisture evaporated varies depending on positional relationship
Solution Approach 1:
The patent implements dynamics by enabling the air blowing part to adjust its target position dynamically. Instead of being constrained to a fixed downstream position, the air blowing part can modify its targeting location along the recording medium path, allowing adaptation to different operational conditions and optimization of evaporation efficiency for various droplet sizes, speeds, and environmental conditions.
Solution Approach 2:
The patent applies parameter changes by modifying the positional parameter of the air-blowing target position. By changing this spatial parameter, the system optimizes the interaction between air flow and moisture vapor, aligning air flow with regions of highest temperature on the recording medium to maximize evaporation rate and adapt to varying operational requirements.
