Adjustable Blade Gap Safety Razor Base Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional safety razors lack adjustable mechanisms to customize the aggressiveness of the shave, which can lead to unintended changes in blade gap and angle, causing irritation and requiring multiple razors for varying beard lengths and user skill levels.
Innovation Solution
A safety razor design featuring a double-sided base plate with adjustable blade gaps and angles, allowing up to four different settings per base plate, enabling customizable aggressiveness without the need for multiple razors, and a modular kit with interchangeable aggressiveness-defining portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional safety razors use a fixed blade gap design, then the structure is simple and manufacturing is easy, but the user cannot customize aggressiveness for different beard lengths and skill levels
Solution Approach 1:
The base plate incorporates adjustable components that allow the blade gap to be dynamically changed between different predetermined positions. This enables the same razor to adapt to different user needs and beard conditions, transforming a static structure into a dynamic one that can be reconfigured.
Solution Approach 2:
The base plate is divided into multiple predetermined positions for blade gap adjustment. By segmenting the adjustment range into discrete positions, the design achieves versatility without requiring continuous complex mechanisms, balancing adaptability with structural simplicity.
2Adaptability or versatility
If traditional safety razors use a fixed blade angle design, then the manufacturing precision is easier to maintain, but the user experiences irritation when stubble length varies
Solution Approach 1:
The blade angle is made dynamically adjustable through the base plate mechanism, allowing users to change the angle to match their current stubble length and skin sensitivity. This resolves the conflict between fixed precision manufacturing and adaptive performance.
Solution Approach 2:
The design allows changing of geometric parameters (blade gap and angle) through the base plate adjustment mechanism. By providing predetermined positions for these parameters, the system maintains manufacturing precision while enabling user adaptation to different shaving conditions.
3Adaptability or versatility
If users purchase multiple razors for different aggressiveness levels, then they can have the right tool for each condition, but the cost and device quantity increase
Solution Approach 1:
The base plate adjustment mechanism enables a single razor to perform multiple functions by accommodating different blade gap and angle settings. This universal design eliminates the need for users to maintain multiple specialized razors, reducing both quantity and cost.
Solution Approach 2:
By segmenting the aggressiveness range into predetermined adjustment positions, the system provides the functionality of multiple razors within a single device, allowing users to select appropriate settings for different conditions without purchasing separate instruments.
4Adaptability or versatility
If adjustable mechanisms are added to traditional razors, then user customization is enabled, but the reliability of the mechanism may decrease due to potential failure or slippage
Solution Approach 1:
The base plate provides predetermined positions for blade gap and angle adjustments, allowing users to select from pre-engineered stable configurations. This preliminary preparation of adjustment positions ensures mechanical stability while maintaining user customization capability.
Solution Approach 2:
The mechanism allows discrete changes between predetermined parameter positions rather than continuous adjustment. This approach maintains reliability by limiting adjustments to engineered stable positions while still providing user control over shaving aggressiveness.
