Adjustable Razor Assembly for Consistent Hair Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing body shavers lack an efficient mechanism for maintaining consistent hair length over time due to limitations in adjusting the cutting length of blade members, which can lead to uneven shaving and trimming.
Innovation Solution
A body shaver with an adjustable razor assembly that includes a stationary member and an adjustable member, where the distance between them can be adjusted using a threaded turnable cylindrical screw or elongated notched member, allowing for customizable cutting length and improved shaving precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cutting length of blade members is fixed, then the device structure is simple, but the ability to maintain consistent hair length over time is poor
Solution Approach 1:
The patent implements an adjustable cutting length mechanism where the blade member can be moved relative to the guard member along a longitudinal axis. This dynamic adjustment capability allows users to customize the cutting length to maintain consistent hair length over time, resolving the contradiction between adaptability and device complexity by introducing a controlled degree of movement rather than a fixed structure.
Solution Approach 2:
The razor assembly is designed to perform multiple functions: it can both trim and shave body hair, and the adjustable cutting length mechanism allows it to adapt to different hair length requirements. This multi-functionality enhances the ability to maintain consistent hair length across various styling needs while keeping the overall device structure integrated and relatively simple.
2Manufacturing precision
If the blade member is fixed relative to the guard member, then the device is easy to manufacture, but shaving precision and user control are limited
Solution Approach 1:
The patent employs a dynamic adjustment system where the blade member can be repositioned along the longitudinal axis relative to the guard member. This allows for precise control of cutting length while maintaining manufacturing feasibility through a straightforward linear adjustment mechanism with limited degrees of freedom, balancing manufacturing precision with ease of manufacture.
Solution Approach 2:
The razor assembly is segmented into distinct functional components: the guard member, the blade member, and the adjustment mechanism. This segmentation allows each component to be manufactured separately with standard tolerances and then assembled, improving manufacturing precision of individual parts while keeping the overall assembly process manageable and relatively simple.
3Ease of operation
If the cutting length is adjustable, then user control over hair length is improved, but the device complexity increases
Solution Approach 1:
The patent implements a dynamic adjustment mechanism that allows users to control the cutting length by moving the blade member along the longitudinal axis. This provides improved ease of operation with a simple linear adjustment motion, while the device complexity is kept manageable by using a straightforward mechanical adjustment system rather than a complex multi-axis or automated mechanism.
