Staggered Multilayer Trimming Head for Adjustable Haircutting Tracks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair cutting methods using scissors and electric haircutters often result in slanted and uneven surfaces, requiring manual operation with scissors for precise layer cuts, which is time-consuming and inefficient.
Innovation Solution
A staggered multilayer trimming head with an adjustable moving blade design in an electric haircutter, featuring a moving knife module with multiple serrated structures and an adjusting lever system, allowing for single or multiple cutting tracks to achieve various haircutting effects without altering the operator's habits, improving efficiency and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional scissors and electric haircutter are used together for precise layer cuts, then cutting precision is improved, but operation time increases significantly
Solution Approach 1:
The trimming head is segmented into multiple independent cutting units (first cutting unit with fixed blade and first moving blade, second cutting unit with fixed blade and second moving blade) that can operate simultaneously. Each unit has its own serrated structures that can be independently adjusted, allowing parallel cutting operations to achieve precise layering effects without requiring sequential use of multiple tools
Solution Approach 2:
Multiple cutting functions are merged into a single trimming head assembly. The first and second moving blades work together with their respective fixed blades to create multiple cutting tracks simultaneously, combining the precision of scissors with the efficiency of electric haircutting in one integrated device
Solution Approach 3:
The moving blades are designed with adjustable positions along the serrated structures, allowing dynamic reconfiguration of cutting tracks during operation. The adjusting levers enable operators to change the relative positions of moving blades to fixed blades, creating different cutting patterns and layering effects without changing tools
2Productivity
If electric haircutter with single cutting track is used, then operation speed is improved, but cutting versatility deteriorates
Solution Approach 1:
The trimming head is divided into multiple cutting units that can operate independently or in combination. Each unit has its own serrated structures and adjusting mechanisms, allowing operators to select different cutting configurations for different hair types and styles while maintaining high-speed operation
Solution Approach 2:
The trimming head is designed with universal adaptability through multiple adjustable cutting units. By modifying the positions of moving blades relative to fixed blades, the same device can perform various cutting functions including single-track cutting, multi-track cutting, and different layering patterns, eliminating the need for multiple specialized tools
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and precise haircutting with adjustable cutting tracks, enhancing the efficiency and quality of haircuts by allowing for different layering effects without changing the original operating habits of hairstylists.
Implementation Method 1
a motor and a power source installed in the main body, and an electric block coupled to a front end of a rotating shaft of the motor for producing an eccentric rotary motion

AI summary
A staggered multilayer trimming head installed at a front end of an electric haircutter includes a bottom plate, a fixed blade, a moving knife module and a moving swing block. The moving knife module has a first moving knife and at least one second moving knife; an adjusting lever is coupled to the second moving knife for adjusting the position of the second moving knife with respect to the first moving knife quickly, and the moving knife module is coupled to a motor of the electric haircutter with power connection through the moving swing block. In a cutting/shearing operation, the adjustable moving blade allows the cutting and shearing to be adjusted to a single cutting and shearing track or a multiple of tracks, so as to complete various haircutting effects quickly without changing the operator's original operating habit and improve the haircutting efficiency and quality significantly.
