Print Medium Heat Shield Structure for Easy Sheet Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing printing device design faces difficulties in setting the medium between the heating section and the heat shield section due to the risk of the medium's leading end entering the gap between these components, making it challenging to insert the medium correctly.
Innovation Solution
Incorporating a protruding section on the heat shield section that protrudes towards the heating section, guiding the medium's leading end to the holding section and reducing the risk of misalignment during setup, while also allowing for adjustable ventilation and condensation prevention through various configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the medium is guided along the heat shield section to the holding section, then the medium can be transported through the heating zone, but the leading end of the medium may enter the gap between the heat shield section and the holding section, making it difficult to set the medium
Solution Approach 1:
The protruding section is positioned in advance to guide the leading end of the medium before it reaches the gap between the heat shield section and holding section. This preliminary guidance action prevents the medium from entering the gap, thereby solving the misalignment issue during medium setup
Solution Approach 2:
The protruding section acts as an intermediary element between the heat shield section and the holding section. It provides a intermediate guidance surface that directs the medium's leading end along a controlled path, preventing direct entry into the gap while maintaining continuous medium transport
2Object-affected harmful factors
If the heat shield section is positioned close to the heating section, then condensation is reduced, but the medium may contact the heat shield section causing heating issues
Solution Approach 1:
The heat shield section has different functional zones: the protruding section creates a localized guidance area for the medium, while the main body maintains proximity to the heating section for condensation prevention. This local differentiation allows simultaneous achievement of medium protection and condensation control
Solution Approach 2:
The protruding section extends in the transport direction from the heat shield section, creating a three-dimensional guidance structure. This dimensional addition allows the heat shield to maintain close proximity to the heating section for thermal management while the protruding portion provides spatial guidance to prevent medium contact with the main heat shield body
