Problem

Conventional cleaning apparatuses with wide-range motion robots occupy larger installation areas, necessitating a compact solution with a narrow-range motion robot for efficient use of space.

Innovation Solution

A compact cleaning apparatus featuring a single-axis robot with a column and articulated arm portion, partitioned into cleaning and drying stations by a separation wall, allowing for a narrow range of motion while maintaining efficient cleaning and drying capabilities through a multi-axis robot system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a multi-axis robot with wide range of motion is used, then cleaning coverage and flexibility are improved, but installation area increases

Engineering Contradiction:
Improvecleaning coverageVSAvoidinstallation area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The cleaning chamber is divided into multiple stations (cleaning station, drying station, loading station, unloading station) arranged linearly along the robot's travel path. This segmentation allows the robot to perform different operations at different locations, achieving comprehensive cleaning coverage while maintaining a compact linear footprint.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from a multi-axis robot operating in three-dimensional space to a single-axis robot traveling along a linear path with components arranged vertically and horizontally. The cleaning nozzles, drying nozzles, and other components are positioned at different heights and locations along the robot's linear trajectory, effectively using multiple dimensions along a single axis to achieve comprehensive coverage.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If a single-axis robot with narrow range of motion is used, then installation area is reduced, but cleaning capability may be compromised

Engineering Contradiction:
Improveinstallation areaVSAvoidcleaning capability
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The single-axis robot is designed to perform multiple functions through its linear travel path: transporting workpieces between loading and unloading stations, positioning them for cleaning, and coordinating with stationary cleaning and drying nozzles. This multi-functional design compensates for the narrow range of motion, maintaining comprehensive cleaning capability within a compact footprint.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces stationary cleaning nozzles, drying nozzles, and support structures that remain fixed while the single-axis robot moves along a linear path. These stationary components act as intermediaries, providing the necessary cleaning and drying functions without requiring the robot to have complex multi-axis motion capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If cleaning and drying stations are separated by a separation wall, then functional organization is improved, but device complexity increases

Engineering Contradiction:
Improvefunctional organizationVSAvoidstructural complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The cleaning chamber is divided into distinct functional stations (cleaning station, drying station, loading station, unloading station) separated by walls and partitions. This segmentation organizes different operations into discrete zones, improving manufacturing ease by allowing independent design and assembly of each station while maintaining overall system integration through the robot's coordinated motion.

Inventive Principle:
Principle #1Segmentation
