Solution Overview

Problem

Self-moving robots, such as sweeping and mopping robots, have limited functionality and reduced efficiency in cleaning due to the lack of a detachable structure that facilitates quick disassembly and assembly of functional components.

Innovation Solution

A detachable structure is implemented in the self-moving robot, allowing for easy detachment and replacement of cleaning assemblies like the cleaning head and water return mechanism, with a pressure plate and adjustable clamping mechanism for convenient maintenance and repair.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a robot is designed to move and perform tasks autonomously, then its functionality and adaptability are improved, but its structure becomes complex and difficult to manufacture

Engineering Contradiction:
Improverobot functionalityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The robot body is divided into multiple detachable modules including head module, torso module, and leg modules. Each module can be independently manufactured and assembled, reducing overall manufacturing complexity while maintaining full robot functionality through modular combinations

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detachable modules are designed with universal interfaces and standardized connection mechanisms that allow the same modules to be reused in different configurations and applications, enhancing adaptability without proportionally increasing complexity

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

2Adaptability or versatility

If a robot has a complex structure with multiple components, then its functionality is improved, but the manufacturing cost and difficulty increase

Engineering Contradiction:
Improverobot functionalityVSAvoidmanufacturing difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By segmenting the robot into standardized detachable modules, each module can be manufactured independently using optimized processes, reducing overall manufacturing difficulty compared to producing a monolithic complex structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detachable module design allows individual components to be replaced, repaired, or upgraded independently, reducing manufacturing costs by enabling localized production and reuse of functional modules across different robot configurations

Inventive Principle:
Principle #34Discarding and recovering

3Strength

If a robot body is made as a single integrated structure, then its structural strength is improved, but it becomes difficult to repair and replace damaged parts

Engineering Contradiction:
Improvestructural strengthVSAvoidparts replacement difficulty
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The robot body is segmented into detachable modules with reinforced connection structures that maintain overall structural strength while enabling individual modules to be independently removed and replaced for repair or upgrade

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection structures between modules are designed to be dynamically adjustable, allowing for secure attachment during operation to maintain structural integrity, and easy detachment during maintenance for simplified repair access

Inventive Principle:
Principle #15Dynamics
