Solution Overview

Problem

Current hair curling appliances with steam production systems are not ergonomic, requiring users to manually count and control the steam application time, which can be variable and attention-intensive, making the process less efficient and more difficult to manage.

Innovation Solution

Incorporating a duration counting unit and detection system that automatically starts counting when the lock of hair is in the active position, with a signaling system to alert the user when the defined duration is reached, allowing for hands-free steam application and improved user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual time counting is required for steam application, then the device structure remains simple, but the ease of operation deteriorates and user convenience is reduced

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device automatically detects when the hair strand is in the active position and autonomously starts the timer without requiring user intervention. The system serves itself by monitoring its own state and initiating the timing function automatically, eliminating the need for manual time counting while adding minimal complexity through an automatic detection mechanism.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The detection system provides feedback about the strand's position to the control unit, which then automatically activates the timer. This closed-loop feedback mechanism ensures the timer starts precisely when needed based on actual device state, improving operational ease while maintaining reasonable device complexity through intelligent control.

Inventive Principle:
Principle #23Feedback

2Productivity

If manual monitoring of steam application duration is required, then the device remains simple, but productivity and efficiency are reduced due to attention requirements

Engineering Contradiction:
ImproveproductivityVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The timer unit autonomously monitors the steam application duration and automatically triggers the signaling system when the predefined time is reached, without requiring user attention or manual monitoring. This self-service capability increases productivity by freeing the user from continuous monitoring while adding only moderate complexity through automated timing and signaling functions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The control unit receives feedback from the detection system about strand position and automatically manages the timer progression. When the timer reaches the predefined duration, the signaling system provides feedback to the user. This automated feedback loop improves productivity by eliminating manual monitoring requirements while maintaining acceptable device complexity.

Inventive Principle:

Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device automatically detects strand position and activates the timer without user intervention, significantly improving ease of operation. The automatic activation eliminates the need for users to manually start timing, making the device much easier to use despite the added complexity of the detection and control systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical time-keeping with an electronic detection and control system. The detection system uses electrical or electronic means to sense strand position, and the control unit uses electronic timing circuits instead of mechanical timers or manual counting, substituting mechanical operations with electronic automation to improve ease of use.

Solution Approach 1:

The detection system provides precise feedback about when the strand enters the active position, and the electronic timer unit accurately measures the elapsed time with high precision. This feedback mechanism ensures consistent and precise measurement of steam application duration, eliminating the variability of manual timing while adding moderate complexity through electronic detection and timing circuits.

Inventive Principle:
