Solution Overview

Problem

Conventional steamers for ironing laundry often result in uneven steam distribution due to user arm position changes, causing wrist strain and difficulty in maintaining uniform steam spraying.

Innovation Solution

A steamer with a hinge-connected head that rotates horizontally using a motor controlled by a sensor and controller, ensuring consistent steam direction, along with a light emitting unit for operational state and battery charge indication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the steamer is held at different arm positions, then the spraying direction changes, but uniform steam distribution cannot be achieved

Engineering Contradiction:
Improvespraying direction controlVSAvoidsteam distribution uniformity
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The head is made rotatable relative to the handle through a hinge connection, allowing the spraying direction to dynamically adjust and maintain horizontality regardless of handle inclination. The motor actively rotates the head to compensate for arm position changes, ensuring uniform steam distribution while maintaining ease of operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

A sensor detects the inclination angle of the handle and provides feedback to the controller, which then actuates the motor to rotate the head to the correct horizontal spraying position. This closed-loop feedback system ensures that uniform steam distribution is maintained despite changes in user arm position.

Inventive Principle:
Principle #23Feedback

2Manufacturing precision

If the head is made rotatable to maintain horizontal spraying, then steam distribution improves, but device complexity increases

Engineering Contradiction:
Improvesteam spraying horizontalityVSAvoidhead rotation mechanism
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The complex mechanical rotation mechanism is replaced with an electromagnetic motor driven by electronic control. The motor, controlled by a microcontroller based on sensor feedback, provides precise and reliable rotation of the head to maintain horizontal spraying, reducing mechanical complexity while improving control precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If the head returns to original position for storage, then storage ease improves, but additional control complexity is introduced

Engineering Contradiction:
Improvestorage convenienceVSAvoidposition control system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The head automatically returns to its original storage position through motor actuation controlled by the system's existing control unit. When the steamer is turned off or stored, the controller commands the motor to rotate the head back to the initial position, providing self-service functionality that enhances storage convenience without requiring additional complex mechanical return mechanisms.

Inventive Principle:
Principle #25Self-service

AI summary

Provided is a steamer and a method of controlling the same, in which the steamer may uniformly spray steam onto laundry even when a position of a user's arm is changed. To this end, the steamer of the present disclosure includes: a handle having a hinge formed at one end in a longitudinal direction thereof, the hinge protruding in a direction orthogonal to the longitudinal direction; a head which is rotatably connected to the hinge and sprays steam; a motor which rotates the head about the hinge; a sensor which senses an inclination in the longitudinal direction of the handle with respect to a horizontal line; and a controller which according to the inclination sensed by the sensor, operates the motor to rotate the head to a position at which the head may spray steam horizontally.
