Open Rotary Shaver Support Structure for Cleaning Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shavers require complex constructions and additional handling for cleaning due to enclosed chambers, making it difficult to access and clean the shaving heads and drive shafts, leading to increased vulnerability and complexity.
Innovation Solution
The support structure connecting the shaving heads to the handle is designed to be substantially open, allowing the space between the heads and handle to be free from obstacles, enabling easy cleaning and minimizing waste accumulation, with the shaving heads accessible without part removal, and driven by a single or individual drive shafts for enhanced visibility and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an enclosed chamber is used to connect shaving heads to the handle, then the shaving heads are protected and waste materials are contained, but the shaver becomes difficult to clean and requires additional handling to access cleaning areas
Solution Approach 1:
The patent removes the enclosed chamber structure that previously contained waste materials and protected the drive shaft. Instead, the shaving heads are mounted directly to the handle in an open configuration, extracting the chamber function while maintaining protection through the drive shaft's own housing and the handle's structure. This allows direct access to all components for cleaning without disassembly.
Solution Approach 2:
The patent segments the waste collection function from the structural support function. Rather than using a single enclosed chamber for both purposes, the design separates these functions by allowing the shaving heads to be independently mounted to the handle, with waste materials being directed away through openings in the handle structure. This segmentation enables easy cleaning of each component independently.
2Reliability
If an enclosed chamber is used to support the shaving heads, then the structure provides protection and containment, but the construction complexity increases and parts become vulnerable
Solution Approach 1:
The patent extracts the enclosed chamber from the design, eliminating the complex assembly of removable parts required for cleaning. The shaving heads are mounted directly to the handle using a simplified support structure that provides necessary protection without requiring additional chambers or covers, thereby reducing construction complexity and part vulnerability.
Solution Approach 2:
The patent merges the support structure and protection function into a single integrated design. The handle itself provides both structural support for the shaving heads and protection for the drive shaft, eliminating the need for separate enclosed chambers and reducing the number of parts that could fail or require maintenance.
3Quantity of substance
If the space between shaving heads and handle is enclosed, then waste materials are contained, but cleaning becomes difficult especially around drive shaft and narrow corners
Solution Approach 1:
The patent removes the enclosed chamber that previously contained waste materials around the drive shaft and in narrow corners. The open mounting configuration allows water and cleaning solutions to freely access all surfaces, including the drive shaft and corners, eliminating the cleaning difficulties associated with enclosed spaces while waste materials are simply washed away through the open structure.
4Reliability
If the shaving heads are mounted with an enclosed support structure, then the heads are protected, but the visibility of shaving heads during use is reduced
Solution Approach 1:
The patent extracts the enclosed support structure that obscured the shaving heads during use. The open mounting configuration allows light to reach all surfaces of the shaving heads, improving visibility for the user while the heads remain protected by their own housing and the handle's structure. This eliminates the need for additional lighting or transparent materials.

AI summary
A shaver (1) includes a handle (2), at least two rotary shaving heads (5), driven by at least one drive shaft (15; 115; 215) which protrudes from the handle (2), and a support structure (6) for supporting the shaving heads (5) onto the handle (2) so as to have their joined shaving surface(s) extend substantially perpendicular to the at least one drive shaft (15; 115; 215). The support structure (6) is configured such, that a space (A), restricted at one side by the shaving heads (5) and at the opposite side by the handle (2), is substantially open to its remaining, surrounding side.
