Honeycomb Bottom-Face Processing to Prevent Cell Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for manufacturing pillar-shaped honeycomb structures face challenges in preventing adhesion of joining material to the bottom faces, leading to clogging of cells during the joining process, as masks used to prevent adhesion do not adhere closely enough.
Innovation Solution
A bottom face processing method involving the removal of protruding plugged portions from the honeycomb structure using a rotary brush with a decentered rotational axis and suction port, ensuring the mask for preventing adhesion can adhere closely to the bottom faces, thereby preventing cell clogging during the joining of honeycomb segments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mask is applied to the bottom face to prevent adhesion of joining material, then adhesion prevention is improved, but the mask does not adhere closely enough causing cells to be clogged
Solution Approach 1:
The protruding portion is removed in advance before applying the mask, creating a flat surface that enables the mask to adhere closely. This preliminary action eliminates the root cause of poor mask adhesion and prevents cell clogging during the joining process.
Solution Approach 2:
The protruding portion that causes mask adhesion problems is extracted or removed from the bottom face. By taking out this problematic feature, the mask can now adhere properly to the flat surface without being obstructed by the protrusion.
2Manufacturing precision
If the mask adheres closely to prevent cell clogging, then manufacturing precision is improved, but the joining process becomes more complex
Solution Approach 1:
The protruding portion is removed in advance before applying the mask, creating a flat surface that enables the mask to adhere closely. This preliminary action eliminates the root cause of poor mask adhesion and prevents cell clogging during the joining process.
Solution Approach 2:
The protruding portion that causes mask adhesion problems is extracted or removed from the bottom face. By taking out this problematic feature, the mask can now adhere properly to the flat surface without being obstructed by the protrusion.
Applied Scientific Principles
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 method effectively prevents cell clogging by ensuring the mask adheres closely to the bottom faces, allowing for efficient joining of honeycomb segments without damaging the structure and improving working efficiency.
Implementation Method 1
a plurality of brush bristles are brought into contact with the plugged portion of each of the first bottom face and the second bottom face while rotating at least one rotary brush
Implementation Method 2
a suction force is applied to the both bottom faces, thereby dust and removed portions are removed
