Separable Lubrication Pivoting for Shaving Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaving implements face challenges in precision shaving and trimming due to the physical obstruction caused by lubrication components, which hinder accurate blade placement and lead to incomplete or unwanted shaving, especially in hard-to-reach areas.
Innovation Solution
A shaving implement with a separable lubrication system that pivots away from the shaving cartridge during trimming and locks in position, allowing for reduced cartridge movement and improved control, while providing shaving aid directly to the skin during normal shaving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a lubrication strip is affixed to the cap to provide lubrication and shaving aids, then skin comfort is improved, but precision shaving and accurate blade placement are hindered
Solution Approach 1:
The lubrication strip is made movable relative to the cap, allowing it to be dynamically positioned. During normal shaving, the strip remains in contact with the skin to provide lubrication. During precision trimming, the strip can be moved out of the way, eliminating the obstruction problem while maintaining both lubrication benefits and precision capabilities.
2Ease of operation
If the shaving cartridge is made pivotable to accommodate different shaving angles, then ease of shaving is improved, but control and precision during trimming are reduced
Solution Approach 1:
The cartridge maintains its pivotable design for ease of shaving, but a locking mechanism is introduced that can dynamically lock the cartridge in a fixed position during precision trimming operations. This allows the system to adapt between flexible shaving and precise trimming as needed.
Solution Approach 2:
A locking mechanism serves as an intermediary between the pivotable cartridge and the handle. This intermediary component enables the cartridge to either pivot freely for ease of shaving or be locked in position for precision trimming, mediating between the two conflicting requirements.
3Reliability
If the lubrication strip is fixed to the cap to ensure consistent lubrication delivery, then reliability of lubrication is improved, but adaptability for different shaving modes is reduced
Solution Approach 1:
The lubrication strip is designed with movable mounting that allows it to dynamically adjust its position. During wet shaving, the strip remains in its normal lubricating position for reliable lubrication delivery. During dry trimming or precision work, the strip can be moved to a retracted or elevated position, providing adaptability while maintaining reliability in each mode.

AI summary
According to the present invention, a shaving implement (10) includes a shaving cartridge (12) and a handle (14). The shaving cartridge includes a frame (16) and a separable lubrication (18). The separable lubrication includes a shaving aid (24). The shaving cartridge is pivotable relative to the handle between a neutral position (see e.g., FIG. 1) and a rearward position (see e.g, FIG. 2), and the separable lubrication is pivotable relative to the frame between a forward position (see e.g., FIGS. 1 and 2) and a locked position. During normal shaving, the separable lubrication is rotated toward the forward position and can pivot relative to the handle with the frame. When the separable lubrication is in the locked position, the separable lubrication is located in a position away from the skin during normal shaving and the pivoting of the frame relative to the handle is generally limited, or altogether eliminated.
