Solution Overview

Problem

Household robots used for tasks like cleaning and mowing are often heavy and costly due to additional features and sensors, making them difficult for small or elderly users to handle and move, especially when accessing different floors or areas.

Innovation Solution

An autonomous household appliance with a wire-bound coupling interface that temporarily connects to a smart device for accessing sensor information, allowing the appliance to perform tasks with enhanced functionality while maintaining a lightweight and cost-effective design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional features and sensors are integrated into the robot, then functionality and performance are improved, but weight and cost increase

Engineering Contradiction:
ImprovefunctionalityVSAvoidweight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The system divides functionality into two segments: core functions permanently integrated into the robot (task unit, basic sensors, processor) and additional functions temporarily provided by an external smart device (camera, microphone, advanced sensors). This segmentation allows the robot to gain enhanced functionality when needed without permanently carrying the additional weight.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a wireless communication interface as an intermediary between the robot and the user's smart device. This intermediary enables the robot to access additional sensors and processing power from the external device without physically integrating them, thus avoiding the weight penalty while maintaining functionality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If additional features and sensors are integrated into the robot, then functionality and performance are improved, but manufacturing cost increases

Engineering Contradiction:
ImprovefunctionalityVSAvoidcost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The robot's processor and wireless interface are designed to be universal, capable of working with multiple different smart devices (smartphones, tablets, computers). This universality allows the same basic robot hardware to access a wide range of additional functions from the user's existing devices, eliminating the need to manufacture multiple specialized robot versions.

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

Solution Approach 2:

Instead of physically copying expensive sensors and processing units into the robot, the system creates a virtual copy by establishing a wireless connection to the user's smart device which already contains these capabilities. The robot accesses functionality through data transmission rather than physical duplication, significantly reducing manufacturing costs.

Inventive Principle:
Principle #26Copying

3Ease of operation

If the robot is made lighter by removing features, then ease of handling is improved, but functionality is reduced

Engineering Contradiction:
Improveease of handlingVSAvoidfunctionality
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system implements dynamic functionality where the robot can switch between different operational modes: basic mode using only integrated components for lightweight operation, and enhanced mode where additional functionality is activated through wireless connection to a smart device. This dynamic adaptability allows the robot to optimize between weight and functionality based on task requirements.

Inventive Principle:
Principle #15Dynamics
