Solution Overview

Problem

Conventional handy stick cleaners require manual adjustment of the head length by each user, leading to inconvenience and impaired usability for multiple users due to varying user heights and cleaning preferences.

Innovation Solution

An AI-powered handy stick cleaner that automatically adjusts the head length using a head length calculation model learned via supervised learning, incorporating user height, pressure sensing values, and head angle to optimize the cleaning experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual adjustment of head length is implemented, then each user can adjust according to their height, but multiple users experience inconvenience due to repeated adjustments

Engineering Contradiction:

Improvehead length adjustmentVSAvoidtime for adjustment

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The cleaner automatically adjusts the head length based on sensor data (pressure, acceleration, gyroscope) and stored user profiles without requiring manual intervention. The system identifies the current user and autonomously sets the optimal head length, eliminating the need for users to manually adjust the head each time they use the cleaner.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

User profiles including height information and preferred head lengths are pre-stored in the cleaner's memory. When a user approaches or uses the cleaner, the system retrieves the corresponding profile and pre-configures the head length before the user begins cleaning, avoiding any adjustment delays.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If automatic head length adjustment is implemented, then usability for multiple users is improved, but device complexity increases

Engineering Contradiction:

Improvemulti-user adaptabilityVSAvoidcontrol system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cleaner uses a single integrated sensor system (pressure sensor, acceleration sensor, gyroscope sensor) that serves multiple functions: identifying user presence, determining user posture, and calculating optimal head length. The same hardware components support both single-user and multi-user scenarios through profile storage and recognition algorithms.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent replaces manual mechanical adjustment with an automated control system that uses sensors and a processor to determine and adjust head length. The mechanical adjustment mechanism remains but is now controlled electronically based on sensor inputs and stored profile data, reducing the need for complex manual adjustment mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An artificial intelligence cleaner may determine a length of a head from user cleaning information including a height of a user, a pressure sensing value applied to the head and a head angle between the head and the ground using a head length calculation model and control a head motor to have the determined length of the head.
