Self-Cleaning Razor Blade Housing With Spring-Driven Debris Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razors accumulate shaving debris, which requires manual cleaning methods that are ineffective and risky, especially when water or cleaning materials are not available.
Innovation Solution
A razor with integrated self-cleaning capabilities, featuring a blade housing with a spring-activated cleaning element that slides along the blade to remove debris, controlled by trigger handles on either side, ensuring safe and non-obstructive operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual cleaning methods (blowing or brushing with hand) are used to remove shavings, then the blade can be cleaned without water or rag, but the cleaning effectiveness is poor and there is risk of injury from exposed blade
Solution Approach 1:
The cleaning element is activated by the user's own shaving motion, automatically cleaning the blade during normal razor operation without requiring separate manual cleaning actions. The spring mechanism stores energy during shaving and releases it to activate the cleaning element, making the system self-servicing during use
Solution Approach 2:
A cleaning element acts as an intermediary between the user's hand and the blade surface. This intermediary component performs the cleaning function while the user's hand remains protected from direct contact with the sharp blade edge, eliminating the injury risk
2Reliability
If a cleaning mechanism is integrated with the razor, then cleaning effectiveness is improved and safety is enhanced, but the device complexity increases
Solution Approach 1:
The cleaning element serves multiple functions: it cleans the blade surface, channels debris away from the cutting area, and can be activated by the user's natural shaving motion. This multi-functionality justifies the added complexity by providing several benefits from a single integrated component
Solution Approach 2:
The cleaning element is designed with dynamic movement capability, allowing it to slide along the blade surface and adjust its position during operation. The spring mechanism provides dynamic activation and resetting, enabling the cleaning element to move only when needed rather than being a static obstruction
3Productivity
If the cleaning element is positioned to effectively clean the blade surface, then cleaning effectiveness is improved, but it may obstruct the cutting area during normal operation
Solution Approach 1:
The cleaning element transitions between static and dynamic states based on operational needs. During normal shaving, it remains stationary and out of the way. During cleaning, it becomes dynamic and slides along the blade surface, ensuring it does not obstruct cutting during normal use but is available when needed
Solution Approach 2:
The cleaning element operates periodically rather than continuously, activating during natural pauses or transitions in the shaving process. The spring mechanism enables this periodic action by storing energy during shaving and releasing it to propel the cleaning element into action when the trigger is activated
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
Effectively clears shaving debris without obstructing normal use, enhancing safety and efficiency by automating the cleaning process.
Implementation Method 1
The blade housing may further contain a spring element that is integrated into the blade housing. The spring element may be adjacent to said blade, with the first end of the spring element connected to the blade housing and the second end of the spring element connected to the cleaning element.

AI summary
The present application discloses a manual razor with self-cleaning capabilities having a handle. The hand having a blade housing at its free end. The blade housing having a razor blade held that firmly, but removable held within the blade housing. The blade housing may further contain a spring element that is integrated into the blade housing. The spring element may be adjacent to said blade, with the first end of the spring element connected to the blade housing and the second end of the spring element connected to the cleaning element. The cleaning element is snugly coupled with the cutting area of the blade, preferably encircling both sides of the cutting area, as well as the edge of the blade. The cleaning element is configured to be displaced or to slide forward and back along the length of the blade in an attempt to clear hair bristles and other shaving debris from the surface of the cutting area.
