Inkjet Printer Thermal Insulation for Compact Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inkjet printers face challenges with heat management due to heat sources like motors, which can affect the ink in the ink container portions, especially in compact designs where thermal conductance is a concern.
Innovation Solution
A low thermal conductance part, such as a space formation unit or heat insulating member, is positioned between the heat sources and the ink container portions to reduce heat transfer, potentially integrated within the tank or provided externally, allowing for effective heat management without increasing the printer's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact printer design is implemented with heat sources like motors, then the printer size is reduced and functionality is improved, but heat transfer to the ink container portion increases causing thermal issues
Solution Approach 1:
A low thermal conductance part is positioned between the heat source and the ink container portion to act as a thermal barrier. This intermediary component reduces heat transfer from the motor to the ink while allowing the compact printer design to be maintained, thus resolving the contradiction between small size and temperature control.
2Temperature
If heat insulating measures are added to protect ink from heat sources, then ink temperature stability is improved, but device complexity increases
Solution Approach 1:
The low thermal conductance part is integrated into the existing tank structure or positioned as part of the overall assembly, merging the heat insulation function with the existing components. This approach provides temperature stability while minimizing the increase in device complexity by combining functions rather than adding separate systems.

AI summary
For printers there are issues relating to consideration to be given to heat sources. A printer is provided with a printhead capable of executing printing on a printing medium by jetting an ink onto the printing medium, a tank having an ink container portion capable of containing ink to be supplied to the printhead, and a heat source. A low thermal conductance part that reduces thermal conductance is positioned between the heat source and the ink container portion.
