Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inkjet printing devices face difficulties in drying ink on relatively thick recording media due to inadequate heat transmission from the platen heater.
Innovation Solution
An ink drying device with a heat generator and a heat diffusion layer on its counter plate, which discharges heat and air through discharge holes to efficiently dry ink on the recording medium, even if it is thick.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a platen heater is used to heat the recording medium, then ink drying is promoted, but heat transmission becomes insufficient when the recording medium is relatively thick
Solution Approach 1:
The patent introduces a heat diffusion layer as an intermediary component between the platen heater and the recording medium. This heat diffusion layer is designed to uniformly distribute and transmit heat across the surface of the recording medium, ensuring effective heat transmission even when the medium is relatively thick. The heat diffusion layer acts as a mediator that overcomes the heat transmission limitation imposed by increased medium thickness.
2Ease of operation
If the recording medium is made relatively thick, then material handling is improved, but ink drying efficiency decreases due to poor heat transmission
Solution Approach 1:
The heat diffusion layer serves as an intermediary that enables effective heat transmission through relatively thick recording media. By uniformly distributing heat across the medium surface, it maintains high ink drying efficiency even when the medium thickness is increased for better material handling characteristics.
Solution Approach 2:
The patent changes the thermal parameters of the system by introducing a heat diffusion layer with specific thermal conductivity properties. This modifies the heat transmission characteristics to accommodate thicker recording media while maintaining drying efficiency, effectively decoupling the relationship between medium thickness and drying performance.
