Processing Chamber Drawer Filtration for Clean Filter Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional processing machines expose foreign matters like chips and steam to the outside, making them difficult to maintain and potentially hazardous, as well as aesthetically unpleasing due to exposed filters and coolant vapor.
Innovation Solution
A processing machine design featuring a drawer with a filter system that guides and filters processing liquid within the machine, preventing overflow and exposure of contaminants, with a drawer that can be pulled out for easy maintenance and filter replacement, ensuring cleanliness and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter is exposed to the outside for easy maintenance, then ease of operation is improved, but foreign matters and steam are exposed to the outside causing contamination and safety issues
Solution Approach 1:
The filter is nested within the drawer structure, which is itself nested within the processing chamber. The drawer can be pulled out to an intermediate position where the filter becomes accessible for maintenance while remaining contained within the drawer boundaries, preventing exposure of foreign matters and steam to the external environment.
Solution Approach 2:
The drawer acts as an intermediary structure between the filter and the external environment. It provides a controlled interface that allows filter access while maintaining containment, solving the contradiction between maintenance accessibility and contamination prevention.
2Ease of operation
If the drawer is pulled out completely for filter access, then ease of operation is improved, but processing liquid may overflow to the rear of the drawer
Solution Approach 1:
The front plate is designed to extend to the vicinity of the upper surface of the tank before the drawer is pulled out. This preliminary structural arrangement prevents processing liquid from flowing out to the rear of the drawer when the drawer is pulled out for filter maintenance.
Solution Approach 2:
The drawer is designed with multiple positions (fully retracted, intermediate, and fully extended). The intermediate position allows filter access while maintaining liquid containment, providing dynamic flexibility in operation modes.
3Manufacturing precision
If the filter is positioned low for effective filtration, then manufacturing precision is improved, but foreign matters may be exposed to the outside
Solution Approach 1:
The filter is nested within the drawer structure that is contained in the processing chamber. This nesting arrangement allows the filter to be positioned at an effective height for filtration while the drawer boundaries prevent exposure of foreign matters to the external environment.
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
The design maintains a clean and safe environment by containing contaminants within the machine, preventing coolant vapor and chip exposure, enhancing aesthetics and operational ease.
Implementation Method 1
a bottom plate connected to the front plate and the pair of side plates, the bottom plate including a filter disposed in a front portion

AI summary
Provided is an easy and clean processing machine. The processing machine includes a processing chamber having a discharge port; a tank having an inflow port with a gap from the discharge port; a drawer to be stowed in the processing chamber and pulled out rearward from the processing chamber, the drawer including a front plate, a pair of side plates, and a bottom plate including a filter disposed in a front portion, a guide including a stopper; and a slider including a latch portion to collide with the stopper to stop the drawer at an intermediate position. The discharge port is located above the bottom plate, and the filter is located above the inflow port when the drawer is located at the intermediate position.
