Universal Trimmer Blade Adjuster for Variable Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair trimmers lack a universal adjuster for trimmer blades, requiring separate adjusters for each model, which limits versatility and accuracy in achieving the critical clearance between the cutter and comb blades for safe and smooth shaving.
Innovation Solution
The development of a universal trimmer blade adjuster (UTBA) with two models: the rotation (or inclination) plate based UTBA (RUTBA) and the sliding block based UTBA (SUTBA), both using clamps to ensure precise adjustments, allowing for fine-tuning of the clearance between the cutter and comb blades, with RUTBA utilizing a rotating plate and SUTBA employing a levelling plate and slider bar for non-linear and variable adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate adjuster is designed for each trimmer model, then the adjustment precision for that specific model is optimized, but the device complexity and the number of different adjusters required increases
Solution Approach 1:
The patent designs a universal trimmer blade adjuster that can accommodate multiple trimmer models through a standardized interface system. The adjuster includes a base plate with multiple mounting holes and adjustable components that can be positioned to fit different comb blade lengths and configurations, allowing a single adjuster design to serve multiple trimmer models while maintaining precise clearance adjustment capability
2Productivity
If the cutter blade is positioned closer to the comb blade end, then the trimming efficiency is improved, but the safety is compromised due to risk of cutting through skin
Solution Approach 1:
The patent implements a dynamic adjustment mechanism that allows users to vary the clearance distance between the cutter blade and comb blade end according to different trimming needs. The rotating plate with angular markings and sliding block with position indicators enable precise control of the cutter blade position, allowing optimization of trimming efficiency while maintaining safety by adjusting clearance to appropriate levels for different hair types and skin conditions
3Adaptability or versatility
If a universal adjuster design is created to fit all trimmer models, then the adaptability is improved, but the manufacturing precision for each specific model may be compromised
Solution Approach 1:
The patent divides the adjuster into multiple independently adjustable segments and components. The base plate is segmented with multiple mounting hole positions, the rotating plate can be adjusted to different angular positions, and the sliding block can be positioned at various locations along its track. This segmentation allows each component to be independently optimized for different trimmer models while maintaining overall universal compatibility, thereby preserving manufacturing precision across diverse applications

AI summary
There are many trimmer models with 2 main parts, the static comb blade and the side moving cutter blade driven by electric motor/vibrator. These blades differ in many ways, shapes, sizes . . . which require fine adjustments and tenth of millimeter clearance at the end of the blades. Some models come with an adjuster that fits its model only with a fixed clearance that cannot be modified and does not fit other models. The proposed inventions are universal trimmer blades adjusters that fit most trimmer blades models and the clearance can be varied to meet the users' requirements. First invention design has one moving part with non-linear smooth adjustments and second invention design has two moving parts with linear fine adjustments.
