Filter Drawer Positioning for Clean Processing Machines
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, and existing designs do not effectively contain processing liquids, leading to cleanliness and safety issues.
Innovation Solution
A processing machine with a processing chamber, a tank, and a drawer system that includes a filter and guide mechanism to contain and filter processing liquids, preventing overflow and exposure of contaminants, while allowing easy maintenance and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the drawer is pulled out completely for maintenance, then the filter is accessible for cleaning, but processing liquid may overflow to the rear or lateral sides of the drawer
Solution Approach 1:
The drawer is designed with dynamic positioning capability, allowing it to be stopped at multiple positions (fully retracted, intermediate, and fully extended) along the guide rail. The guide rail includes stoppers at different locations that engage with the drawer to prevent unintended movement and liquid overflow while maintaining accessibility for maintenance operations.
Solution Approach 2:
The guide rail acts as an intermediary mechanism between the drawer and the processing chamber. It controls the drawer's movement path and positioning, ensuring that the drawer can be accessed for maintenance without allowing processing liquid to escape to harmful areas. The guide rail mediates between the need for accessibility and the need for containment.
2Ease of repair
If the drawer is positioned to allow filter cleaning, then maintenance is facilitated, but foreign matters and steam may be exposed to the outside
Solution Approach 1:
The drawer's dynamic positioning along the guide rail allows operators to select appropriate positions for different operations. During maintenance, the drawer can be extended to an intermediate position where the filter is accessible through the front opening, while the rear and lateral sides remain contained within the processing chamber, preventing contaminant exposure.
Solution Approach 2:
The drawer structure is segmented into functional zones: the front portion with the filter and opening for maintenance access, and the rear/lateral portions that remain enclosed within the processing chamber. This segmentation allows selective access to the filter while maintaining containment of harmful factors in other areas.
3Ease of repair
If the drawer structure is extended to improve filter accessibility, then maintenance becomes easier, but the device complexity increases
Solution Approach 1:
The guide rail with integrated stoppers provides a simple yet effective dynamic positioning system. Rather than complex actuators or control systems, the design uses passive mechanical stoppers that engage with the drawer at predetermined positions, achieving multiple functional states (retracted, intermediate, extended) with minimal complexity.
Solution Approach 2:
The drawer system is designed to be manually operable without requiring complex control mechanisms. Operators can easily move the drawer along the guide rail and engage/disengage stoppers by hand, making the system self-service friendly while maintaining controlled positioning to prevent liquid overflow and contaminant exposure.

AI summary
Provided is an easy and clean processing machine. The processing machine (10) includes a processing chamber (11) having a discharge port (18); a tank (15) having an inflow port (15a) with a gap from the discharge port (18); a drawer (24) to be stowed in the processing chamber (11) and pulled out rearward from the processing chamber (11), the drawer (24) including a front plate (25), a pair of side plates (27), and a bottom plate (31) including a filter (32) disposed in a front portion, a guide (16) including a stopper (19); and a slider (34) including a latch portion (37) to collide with the stopper (19) to stop the drawer (24) at an intermediate position. The discharge port (18) is located above the bottom plate (31), and the filter (32) is located above the inflow port (15a) when the drawer (24) is located at the intermediate position.
