Solution Overview

Problem

Garment steamers often require users to maintain pressure on a push button for continuous steam delivery, leading to physical fatigue and increased water and energy consumption, while designs without trigger control result in limited steam control and inefficiencies.

Innovation Solution

A garment steamer with a steamer head equipped with a laser sensor to measure the distance between the steamer head and the garment, controlling steam delivery based on this distance to optimize steam supply and reduce user effort, featuring a microcontroller or electronic valve to manage steam generation and consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If push button trigger control is used to control steam delivery, then water and energy efficiency are improved, but user physical fatigue increases and operation complexity increases

Engineering Contradiction:
Improveenergy consumptionVSAvoiduser physical fatigue
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The steamer head automatically detects the presence of a garment and controls steam delivery without requiring continuous user input. The sensor system enables the device to serve itself by autonomously activating steam generation when needed and deactivating when not needed, eliminating the need for users to maintain pressure on push buttons.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mechanical push button trigger system is replaced with an optical or proximity sensor system that automatically detects garment presence. This substitution eliminates the mechanical interaction requiring user physical effort while maintaining precise control over steam delivery timing.

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

2Loss of energy

If push button trigger control is used to control steam delivery, then water and energy efficiency are improved, but device complexity increases

Engineering Contradiction:
Improveenergy consumptionVSAvoidcontrol mechanism complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The control function is extracted from the handle area and integrated directly into the steamer head. By placing the sensor and control electronics in the steamer head itself, the system achieves automatic control without requiring complex wiring and control mechanisms spanning the entire device length.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The steamer head is given multiple functions: it generates steam, detects garment presence, and autonomously controls steam delivery timing. This multi-functionality consolidates control logic into a single location, reducing overall system complexity despite adding automation capabilities.

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

3Ease of operation

If continuous steam output is provided without trigger control, then ease of operation is improved, but water and energy consumption increase

Engineering Contradiction:
Improveoperation simplicityVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

Instead of continuous steam output, the system uses periodic action by activating steam generation only during periods when a garment is detected near the steamer head. The sensor continuously monitors and triggers steam delivery in discrete periods of need, eliminating waste during idle periods.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The sensor system provides feedback about garment presence to the control system, which then adjusts steam delivery accordingly. This feedback loop ensures steam is delivered only when needed, maintaining operational simplicity while preventing unnecessary energy and water consumption.

Inventive Principle:
Principle #23Feedback

4Ease of operation

If continuous steam output is provided without trigger control, then user fatigue is reduced, but control precision over steam delivery is limited

Engineering Contradiction:
Improveuser fatigueVSAvoidsteam delivery control precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The steamer head autonomously determines the precise timing for steam delivery based on sensor detection of garment presence. This self-service capability provides precise control over when steam is delivered without requiring user intervention, achieving both ease of operation and control precision.

Inventive Principle:
Principle #25Self-service
