Scissors With Integrated Comb And Blade Measurement Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scissors used for hair cutting lack a reliable method for maintaining consistent measurement of hair length, often requiring estimations by the hair cutter or the use of additional tools like rulers, which can slow down the process and increase cleaning and sterilization time.
Innovation Solution
The integration or attachment of measurement portions on the scissors, such as engraved metrics on the blade surfaces or removable stickers, allows for precise hair length cutting without additional tools, combined with integrated comb portions for easier hair isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional scissors are used for hair cutting, then the cutting function is provided, but measurement precision and consistency are poor requiring estimations or additional tools
Solution Approach 1:
The patent combines measurement scales and comb teeth directly onto the scissor blades, merging the functions of cutting, measuring, and combing into a single tool. This eliminates the need for separate rulers or measurement tools, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The scissors are designed to perform multiple functions: cutting hair, measuring hair length, and combing/isolating hair sections. The measurement scales and comb portions integrated on the blades enable the same tool to provide both cutting and measurement capabilities, achieving universality that resolves the need for additional tools.
2Measurement precision
If additional tools like rulers are used for measurement, then measurement precision improves, but productivity decreases due to increased cleaning and sterilization time
Solution Approach 1:
By integrating measurement scales and comb features directly onto the scissor blades, the patent eliminates the need for separate measurement tools. This reduces the number of items that require cleaning and sterilization, thereby maintaining productivity while achieving precise measurement.
3Measurement precision
If measurement portions are engraved on the blade surfaces, then measurement precision improves, but manufacturing complexity increases
Solution Approach 1:
The patent replaces traditional mechanical measurement tools (separate rulers) with engraved measurement scales on the blade surfaces. This substitution integrates the measurement function into the existing scissor structure, achieving precise measurement while avoiding the complexity of assembling multiple components.
4Ease of operation
If integrated comb portions are added to the scissors, then ease of operation improves for hair isolation, but device complexity increases
Solution Approach 1:
The patent merges the comb function with the scissor blades by integrating comb portions directly onto the blade surfaces. This combination allows hair isolation and sectioning to be performed with the same tool used for cutting, improving ease of operation while avoiding the need for separate combing tools.
