Shaving Head Cleaning Jet Through a Single Track Sector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaving systems are inefficient in thoroughly cleaning the shaving unit and often require excessive amounts of cleaning liquid or strong cleaning agents.
Innovation Solution
The shaving system incorporates injection nozzles positioned to direct cleaning liquid through a single sector of the annular shaving track, allowing it to flow out through the remaining sector, creating a strong current for effective debris removal, and includes a sloped orientation and rotating cutters for enhanced cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cleaning liquid is sprayed onto the shaving head from above, then the cleaning liquid can be distributed throughout the shaving head, but the cleaning is not thorough and requires excessive amounts of cleaning liquid
Solution Approach 1:
Instead of spraying cleaning liquid from above onto the shaving head, the invention inverts the approach by positioning injection nozzles at the bottom of the receiving pit to inject cleaning liquid upward through the shaving unit from below, enabling thorough cleaning with reduced liquid consumption
Solution Approach 2:
The invention uses hydraulic injection nozzles positioned at the bottom of the receiving pit to deliver cleaning liquid through the shaving unit from below, creating an efficient cleaning flow that reduces the total amount of cleaning liquid required while improving cleaning effectiveness
2Reliability
If multiple nozzles are arranged to strike the complete surface of the shaving head, then more thorough cleaning is achieved, but the device complexity increases
Solution Approach 1:
The invention segments the cleaning function by using a single injection nozzle that directs cleaning liquid through specific sectors of the annular shaving track, allowing thorough cleaning of critical areas without requiring multiple nozzles arranged around the entire circumference
Solution Approach 2:
The invention applies local quality by concentrating cleaning liquid injection into a single sector of the annular shaving track where it is most needed, rather than distributing nozzles uniformly across the entire shaving head surface
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
Achieves thorough cleaning of the shaving unit with reduced cleaning liquid usage and improved debris removal, ensuring a balanced and efficient cleaning process.
Implementation Method 1
at least one injection nozzle (40) arranged and positioned in the receiving pit (28) for forming a jet of cleaning liquid (10) delivered from the conduit (62) via the plenum chamber (63) directly through one or more of the hair-entry openings (27)
Implementation Method 2
The bottom wall (76) of the housing (22) has a sloped orientation

AI summary
A shaving system (100) includes a shaving device (12) having a shaving unit (38) and a cleaning device (14) for cleaning the shaving unit, the shaving unit having at least one hair-cutting unit (25) having an outer hair-cutting member with an annular shaving track (37) with a plurality of hair-entry openings (27) and an inner hair-cutting member rotationally arranged inside of the outer hair-cutting member. The cleaning device (14) includes a liquid-injection nozzle positioned in a receiving pit of the cleaning device for generating a jet of the cleaning liquid that, when the shaving unit is supported in a cleaning position by the cleaning device, propagates directly through one or more of the hair-entry openings (27) of the shaving unit only in a single sector (41) of the annular shaving track (37) of the outer hair-cutting member (27) extending over at most one half of the annular shaving track.
