Razor Handle Through-Hole for Debris Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cartridge razors face difficulties in washing due to their narrow intervals and complex internal structures, leading to incomplete discharge of shaving debris and difficulty in cleaning the central portion, especially with handles connected to the rear surface.
Innovation Solution
A razor design featuring a handle with a through-hole extending along its profile, providing open areas for water flow and debris discharge, and a hook locking mechanism for secure coupling with the razor blade cartridge, which includes a blade housing with a guard and seating portions for the blades, facilitating easier washing and debris removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cartridge is designed with a narrow interval between razor blades and complex internal structure to improve shaving performance, then the razor blade can effectively contact the skin, but washing is not smoothly performed and shaving debris remains inside the cartridge
Solution Approach 1:
The handle is divided into multiple sections with through-holes created at different locations (front surface, rear surface, and side surfaces). This segmentation of the washing function across multiple access points allows water to reach previously inaccessible internal areas of the cartridge, resolving the contradiction between complex internal structure and washing ease.
Solution Approach 2:
The through-holes act as intermediary channels that facilitate water flow into the narrow intervals between razor blades and internal cartridge components. These holes serve as mediators between the external washing water and the previously inaccessible internal structures, enabling effective cleaning while maintaining the complex design needed for shaving performance.
2Stability of the object's composition
If the handle is connected to the rear surface of the cartridge to provide control and stability, then the razor can be effectively controlled by the user, but the central portion of the cartridge becomes difficult to wash
Solution Approach 1:
The washing access is extended from a single rear approach to multiple dimensions by creating through-holes on the front surface, rear surface, and side surfaces of the handle. This multi-dimensional approach to water access allows washing of the central cartridge portion from multiple angles, overcoming the limitation imposed by the rear-connected handle design.
3Adaptability or versatility
If the cartridge is designed with complex internal structure to accommodate multiple razor blades and guards, then shaving functionality is improved, but complete discharge of washing water and debris becomes difficult
Solution Approach 1:
Multiple through-holes are created at different locations on the handle (front surface, rear surface, side surfaces) to provide multiple discharge pathways. This segmentation of the discharge function ensures that washing water and debris can be efficiently removed from all areas of the complex cartridge internal structure, resolving the contradiction between functional complexity and washing efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enhances the washing efficiency of the razor blade cartridge by allowing water to flow through the handle and discharge debris effectively, particularly addressing the challenge of cleaning the central portion, which was previously difficult to reach.
Implementation Method 1
a through-hole which extends along at least a portion of a profile of the handle is formed on the handle; washing water is supplied through a through-hole which extends along a portion of a profile of a handle

AI summary
The present disclosure relates to a razor which is easy to wash and includes a through-hole connected to a cartridge via a handle, the razor including a razor blade cartridge including at least one razor blade, and a handle coupled to a rear surface of the razor blade cartridge, wherein a through-hole which extends along at least a portion of a profile of the handle is formed on the handle, and the through-hole includes a first open surface formed to face the rear surface of the razor blade cartridge and a second open surface which is opposite the first open surface such that, since washing water is supplied through the through-hole which extends along a portion of the profile of the handle, washing of the razor blade cartridge can be facilitated, and by providing an open surface which is more perforated downward, discharge of washing water and shaving debris can be facilitated.
