Handheld Hair Trimmer with Imaging-Based Dynamic Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair cutting devices require significant user skill and are cumbersome, making it difficult to accurately position and move them for precise cutting, especially when cutting one's own hair, as they can obstruct the view and are uncomfortable when mounted on the head.
Innovation Solution
A hand-held treating device equipped with an imaging module that generates information about its position relative to the body, allowing the controller to adjust the distance between the treating unit and a guide face dynamically, enabling precise positioning and varying treatment characteristics without the need for additional components or indicators on the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a trimmer is used to cut hair, then hair can be cut to a consistent length, but the device is difficult to accurately position on the user's head and requires significant user skill
Solution Approach 1:
The system uses an imaging module to capture images of the user's head and determining features, then provides real-time feedback by controlling the guide face position based on the determined position and orientation, enabling automatic positioning without requiring significant user skill
Solution Approach 2:
The system performs self-positioning by automatically determining the guide face position relative to the user's head using image processing and feature recognition, eliminating the need for manual positioning by the user
2Adaptability or versatility
If the device is moved over areas to cut hair, then different areas can be treated, but the device and user's hand and arm impede the user's view making it difficult to position accurately
Solution Approach 1:
The imaging module acts as an intermediary between the user and the device, capturing images and determining head features to enable indirect observation and precise positioning without requiring the user to directly view the area being treated
3Measurement precision
If a unit is mounted on the user's head to provide positional guidance, then positioning accuracy is improved, but the system becomes cumbersome and uncomfortable
Solution Approach 1:
The system extracts the imaging and positioning functions from a head-mounted unit and relocates them to a handheld device with an integrated imaging module, eliminating the need for head-mounted components while maintaining positioning accuracy

AI summary
The present application relates to a system and a method for treating a part of a body to be treated, particularly a system and a method for cutting hair on a part of a body to be treated. The system has a hand-held treating device having a treating unit, and an imaging module configured to generate information indicative of the position of the treating device relative to the part of the body to be treated based on an image of a part of the body and the treating device. The system also has a guide face configured to space the treating unit from the part of the body to be treated during use of the system. A controller is configured to change a distance between the treating unit and the guide face in dependence on the information generated by the imaging module.
