Segmented Hair Trimmer Controller for Pattern Creation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair cutting devices lack the capability to easily create intricate patterns, such as letters, words, or images, due to their inability to selectively control hair cutting across the full width of the cutting unit, making it difficult and time-consuming to achieve fine details in haircuts.
Innovation Solution
A hand-held treating device with a treating unit that can selectively enable and disable treating actions of its portions independently, controlled by a controller receiving information on a predetermined pattern, allowing for precise creation of patterns by enabling or disabling cutting actions based on position, speed, or time, using mechanisms like deflector elements or individually activated cutting blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional trimmers are used to create patterns, then the device can cut hair, but it requires great skill and cannot easily create intricate patterns
Solution Approach 1:
The treating unit is divided into multiple independently controllable portions or zones across its width. Each portion can be selectively activated or deactivated by the controller based on the pattern requirements, allowing precise control over which areas of hair are treated. This segmentation enables complex pattern creation without requiring operator skill.
Solution Approach 2:
The patent replaces the manual mechanical control system with an automated electronic control system. The controller receives pattern information and automatically activates/deactivates treating portions, substituting the need for skilled manual operation with automated digital control based on predetermined pattern data.
2Productivity
If the treating unit treats the full width simultaneously, then the cutting speed is high, but the ability to create fine details is lost
Solution Approach 1:
The treating unit width is segmented into multiple independently controllable zones. This allows selective activation of only the necessary portions for the current task, enabling fine detail work when needed while maintaining the capability for full-width treatment when speed is prioritized.
Solution Approach 2:
The system dynamically adjusts which portions of the treating unit are active based on the pattern requirements and device position. The controller can enable or disable specific zones in real-time, allowing the treating width to be dynamically optimized for either speed or precision depending on the operational context.
3Adaptability or versatility
If the treating unit is controlled as a single unit, then the device complexity is low, but the versatility for different patterns is limited
Solution Approach 1:
The treating unit is segmented into multiple independently controllable portions, and the control system is segmented into corresponding control channels. This modular segmentation allows the system to handle diverse patterns while keeping each control element relatively simple, as each portion can be independently managed.
Solution Approach 2:
The controller is designed to receive various types of pattern information and control multiple treating portions universally. This multi-functional control architecture allows the same device to create different patterns (letters, words, images, symbols) without requiring different hardware configurations.

AI summary
A system for treating a part of a body to be treated, comprising a hand-held treating device, the treating device comprising a treating unit; wherein the treating device is configured such that a treating action of each portion of a plurality of portions of the treating unit can be selectively enabled and disabled independently of the treating action of the other portions of the treating unit; and a controller configured to receive information on a predetermined pattern to be created on the part of the body to be treated, and to selectively enable and disable the treating action of the portions of the treating unit according to the received information as the treating device is moved over the part of the body to create the predetermined pattern on the part of the body.
