Haircut Recording Device Using Dynamic Position Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current haircut recording methods are inefficient and lack accuracy, requiring significant manual intervention and time to recreate a haircut, as they rely on storing a pre-existing model of the haircut and struggle to capture the dynamic changes in hair length and style over time.
Innovation Solution
A haircut recording method and system that uses a hair property measurement unit to detect and record actual hair length and position values, providing user feedback to adapt and refine measurements, especially in transition regions, allowing for a more accurate and efficient data collection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pre-existing model of the haircut is stored in a computing device to control the haircutting appliance, then the desired haircut can be reproduced, but the system cannot capture dynamic changes in hair length and style over time
Solution Approach 1:
Instead of storing a pre-existing model and trying to reproduce it, the system inverts the approach by recording the actual hair properties after the haircut is grown and worked with, then using this recorded data to control the appliance for reproducing the haircut. This allows capturing the dynamic state of hair at any point in time rather than relying on a static initial model.
2Loss of information
If machine parameters are recorded during the haircut operation, then haircut data can be obtained, but significant manual intervention and time are required to process and recreate the haircut
Solution Approach 1:
The system performs preliminary recording of hair properties (length, position, etc.) at the time the desired haircut state is achieved. This preliminary capture of data eliminates the need for time-consuming manual measurement and processing later when recreating the haircut, as all necessary parameters are already stored.
Solution Approach 2:
The system replaces manual measurement and processing methods with automated sensing devices that electronically detect and record hair properties. This substitution of mechanical/manual operations with electronic automation significantly reduces the time and effort required to capture and process haircut data.
3Measurement precision
If a standardized measurement pattern is used to record hair length at multiple points, then haircut data can be collected, but the process is inefficient and lacks accuracy in transition regions
Solution Approach 1:
The system applies different measurement strategies to different regions of the head based on local characteristics. In transition regions where hair length changes rapidly, the system increases measurement density and applies adaptive refinement, while in uniform regions it uses standard spacing. This local adaptation improves accuracy where needed without unnecessarily increasing overall measurement time.
Solution Approach 2:
The measurement system is dynamic and adaptive rather than static and fixed. It automatically adjusts measurement density and spacing based on detected hair property variations, concentrating measurements in transition regions and reducing them in uniform areas. This dynamic approach optimizes both accuracy and efficiency by allocating measurement resources where they are most needed.

AI summary
A haircut recording method, system and device, include a computing device having a feedback unit, and a hand-held device having a hair property measurement unit. The measurement unit is configured to detect a hair property value of interest, such as a hair length representing value, when the measurement unit is arranged adjacent to a haired portion. A position detection unit is configured to detect an actual position of the measurement unit. A record control unit is configured to operate the position detection unit for tracking the actual position of the measurement unit, operate the measurement unit for assigning detected hair property values to position values, deduce a condition parameter, such as a quality parameter, and provide user feedback based on the deduced condition parameter.
