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

VSEngineering 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

Engineering Contradiction:
Improvefilter accessibilityVSAvoidprocessing liquid overflow
Core Design Contradiction:
Ease of repairVSObject-affected harmful factors

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
Improvemaintenance accessibilityVSAvoidcontaminant exposure
Core Design Contradiction:
Ease of repairVSObject-generated harmful factors

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #1Segmentation

3Ease of repair

If the drawer structure is extended to improve filter accessibility, then maintenance becomes easier, but the device complexity increases

Engineering Contradiction:
Improvedrawer accessibilityVSAvoidguide and latch mechanism
Core Design Contradiction:
Ease of repairVSDevice complexity

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #25Self-service
