Razor Cartridge Blade Location Indicators for Precision Shaving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in precisely positioning razor blades when shaving sideburns and beards due to the difficulty in identifying the location of the cutting edges, leading to uneven cuts and discontinuities.
Innovation Solution
A razor cartridge with blade location indicators on its outer housing, such as markings or color bands, that visually guide the user to the position of the blades, allowing for precise alignment with the skin, especially when shaving sideburns and beards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the razor cartridge is designed without blade location indicators, then the device structure remains simple, but the user cannot precisely identify blade positions leading to uneven cuts
Solution Approach 1:
The patent applies color coding through blade location indicators (such as colored lines, dots, or bands) on the cartridge housing that correspond to the position of individual blades. This visual coding system allows users to quickly and accurately identify which blade is at which location without adding mechanical complexity, resolving the contradiction between precise blade position identification and simple device structure.
2Adaptability or versatility
If multiple blades are placed in the cartridge without visual indicators, then the cartridge can provide multiple cutting edges, but the user cannot determine the exact location of each blade for precise shaving
Solution Approach 1:
The patent uses color-coded indicators on the cartridge housing that correspond to the position of each blade in the multi-blade configuration. This allows the cartridge to maintain multiple blades for versatile shaving while the color indicators preserve blade position information, enabling users to accurately locate each blade for precise shaving of different facial areas.
Solution Approach 2:
The patent segments the blade location information into discrete visual indicators (such as individual colored lines or dots) that correspond to each blade's position. This segmentation allows users to identify each blade's location independently within the multi-blade cartridge, maintaining both versatility and position awareness.
3Manufacturing precision
If the razor is used for shaving sideburns and beards requiring precise positioning, then high shaving precision is achieved, but the difficulty in locating blades increases the time required for proper positioning
Solution Approach 1:
The color-coded blade location indicators allow users to instantly identify blade positions without trial and error, significantly reducing the time required for proper positioning while maintaining high shaving precision for sideburns and beards.
Solution Approach 2:
The blade location indicators provide preliminary information about blade positions before the user begins shaving, eliminating the need for time-consuming exploration or adjustment during the shaving process. The user can directly position the cartridge based on the visual indicators.

AI summary
A razor cartridge includes an outer housing and one or more blades disposed within the outer housing. In addition, the razor cartridge includes at least one blade location indicator disposed along one or more surfaces of the outer housing for identifying a location of one respective blade within the outer housing.
