Solution Overview

Problem

Existing floor and window scrubbing robots are designed for specific applications, requiring separate purchases and increasing costs, storage space, and user inconvenience due to their distinct designs and functionalities.

Innovation Solution

A multi-functional scrubbing robot that integrates floor sweeping, floor scrubbing, and window scrubbing capabilities, with a window scrubbing device that can be embedded into and removed from a floor scrubbing device, sharing a common mounting recess and power systems to provide a versatile and cost-effective cleaning solution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If floor scrubbing robot and window scrubbing robot are designed separately for specific applications, then each device can perform its dedicated function well, but users need to purchase multiple devices increasing costs and storage space requirements

Engineering Contradiction:
Improvecleaning function versatilityVSAvoidnumber of devices
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The cleaning robot is designed with a universal base body that can perform both floor cleaning and window cleaning functions. The base body includes a floor cleaning system with cleaning rollers and a rubbish collection system, while also providing a mounting structure for window cleaning devices. This allows one device to replace multiple specialized devices, reducing the quantity of devices users need to purchase and store.

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

Solution Approach 2:

The window cleaning function is segmented into a separate, detachable window cleaning device that can be mounted on or removed from the base body. This segmentation allows the window cleaning module to be independently configured while sharing the common base body, power system, and control system, achieving versatility without requiring a completely separate device.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If floor scrubbing robot and window scrubbing robot are designed with distinct structures for different applications, then each device is optimized for its specific use, but they cannot be exchanged for usage requiring both floor and window cleaning

Engineering Contradiction:
Improveapplication scene adaptabilityVSAvoidstructural difference
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base body is designed as a universal platform that can accommodate both floor cleaning operations and window cleaning operations. It includes a mounting recess specifically designed to receive the window cleaning device, allowing the same base body to support different cleaning applications without requiring structural modifications.

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

Solution Approach 2:

The window cleaning device is designed to be nested within or mounted on the base body structure. The mounting recess in the base body provides a integrated housing for the window cleaning device, allowing compact storage when not in use and easy deployment when needed, reducing the overall structural complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If users purchase separate floor scrubbing robot and window scrubbing robot, then each device can be optimized for its specific function, but it renders high costs and more occupied storage spaces

Engineering Contradiction:
Improvefunction-specific performanceVSAvoidstorage space
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The floor cleaning system and window cleaning device are merged into a single integrated cleaning robot system. Both cleaning functions share the common base body, power system, control system, and navigation system. The window cleaning device can be stored within or mounted on the base body, significantly reducing the storage space required compared to having two separate devices.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If separate floor and window scrubbing robots are used, then each device can be specialized for its application, but user experience deteriorates due to need to operate and maintain multiple devices

Engineering Contradiction:
Improveapplication-specific reliabilityVSAvoidoperation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The integrated cleaning robot provides a unified control interface and operation system that manages both floor cleaning and window cleaning functions. Users interact with a single device rather than multiple separate devices, simplifying operation and maintenance while maintaining the specialized performance of each cleaning function through dedicated subsystems.

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

AI summary

The present invention provides a scrubbing robot, including a window scrubbing device, including a suction assembly configured to be sucked to a window body, a first travelling assembly configured to move on the window body, and a window body cleaning system; and a floor scrubbing device, including a second travelling assembly configured to move on a floor and a floor cleaning system, where the body of the floor scrubbing device has a mounting recess, and the window scrubbing device is configured to be capable of being embedded into and removed from the mounting recess. The scrubbing robot is an integrally functional cleaning robot integrating multiple functions of floor sweeping, floor scrubbing, and window scrubbing. After the window scrubbing device is embedded into the floor scrubbing device, a complete floor scrubbing robot is formed; after the window scrubbing device is removed from the floor scrubbing device, an independent window scrubbing machine is formed. It has rich functions and low costs, occupies a smaller storage space, is convenient to operate, and improves user experience.
