Solution Overview

Problem

Existing self-moving devices, such as automatic mowers and vacuum cleaners, face challenges due to high costs of functional modules, complexity in managing multiple models, and the need for users to purchase new machines for each new feature, as well as difficulties in adapting to varying working environments.

Innovation Solution

A self-moving device with a modular design that includes a housing with primary and secondary cavities, a moving module, a primary working module, and a control module, allowing for the selective mounting of different functional modules via interfaces, and ensuring isolation between cavities to prevent water and dirt ingress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manufacturers configure various functional modules to improve device performance, then the device can provide better services and complete tasks more reliably, but the device cost increases significantly

Engineering Contradiction:
Improvedevice performanceVSAvoiddevice cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The device is divided into a base unit and separate functional modules. The housing contains a primary cavity for the control module and a secondary cavity for optional functional modules. This segmentation allows users to purchase only the base unit or add specific functional modules as needed, reducing overall device cost while maintaining reliability when modules are required.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base device is designed with universal interfaces and mounting structures that can accommodate multiple types of functional modules. The secondary cavity and interface design enable the same base unit to work with different functional modules (e.g., sensing modules, communication modules), allowing one device platform to serve multiple functions and reduce the need for separate specialized devices.

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

2Adaptability or versatility

If manufacturers produce machines of different models to meet different user demands, then user needs are satisfied, but device complexity and management difficulty increase

Engineering Contradiction:
Improveuser demand satisfactionVSAvoidmodel management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single base model with standardized interfaces and a secondary cavity can accommodate multiple functional modules, replacing the need for multiple specialized models. Users can configure their desired functionality by selecting different functional modules, while manufacturers manage only one base model design, significantly reducing model management complexity.

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

Solution Approach 2:

The device configuration is made dynamic and adjustable rather than fixed. Functional modules can be added or removed based on user needs, allowing the same physical device to adapt to different requirements without requiring separate models for each configuration scenario.

Inventive Principle:
Principle #15Dynamics

3Reliability

If manufacturers design sealed cavities to prevent water vapor and dirt ingress, then device reliability improves, but manufacturing complexity increases

Engineering Contradiction:
Improveprotection against contaminantsVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The housing is divided into separate sealed cavities (primary and secondary) with defined interfaces. Each cavity can be sealed independently, and the interface between cavities includes waterproof design. This segmented approach allows for simpler manufacturing of each section while maintaining overall reliability through localized sealing at critical interfaces.

Inventive Principle:
Principle #1Segmentation
