Blade-Protecting Cap with Ventilation Opening for Efficient Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blade protection caps for electric razors inefficiently dry the blade portion due to water accumulation between the cap's brim edge and mounting surface, preventing effective drainage and drying.
Innovation Solution
A blade protecting cap with a design featuring a first opening that communicates with the outer space when mounted on a surface, a second opening to prevent closed spaces, and inclined surfaces to facilitate water runoff, ensuring ventilation and efficient drying by allowing water to drain through dewatering holes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the brim edge is designed to abut against the mounting surface to support the electric razor, then the electric razor can be stably mounted in an inverted state, but water accumulates in the space between the brim edge and mounting surface, preventing efficient drying
Solution Approach 1:
The brim edge is segmented into multiple regions: a first region that abuts against the mounting surface to provide stability, and a second region that is elevated to prevent water accumulation. This segmentation allows the brim edge to simultaneously achieve stable mounting and efficient water drainage functions.
Solution Approach 2:
The brim edge is designed with vertical elevation in the second region, creating a stepped three-dimensional structure. This dimensional change allows water to drain away from the mounting surface contact area, preventing water accumulation while maintaining stable support.
2Object-generated harmful factors
If dewatering holes are formed in the cap to drain water, then water can be removed from the blade portion, but water still accumulates in the space between the brim edge and mounting surface, reducing drying efficiency
Solution Approach 1:
Dewatering holes are formed in the blade protecting cap main body to extract and remove water from the internal space where the blade portion is located. This extraction mechanism actively drains water away from the blade area, preventing water accumulation and accelerating the drying process.
3Stability of the object's composition
If the entire circumference of the brim edge abuts against the mounting surface, then the mounted state is stable, but a closed space is formed that traps water, preventing ventilation and drying
Solution Approach 1:
The brim edge contact perimeter is segmented such that the first region contacts the mounting surface for stability while the elevated second region creates an open, non-closed configuration. This segmentation prevents the formation of a closed space, allowing ventilation and moisture evaporation while maintaining stable mounting.
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
Enhances ventilation and drainage between the blade and outer space, enabling more efficient drying of the blade portion and reducing moisture retention, thereby improving hygiene and preventing microorganism growth.
Implementation Method 1
a first opening is formed in the blade protecting cap main body, and in a state where the support portion is allowed to abut against a mounting surface... the first opening communicates with an outer space of the blade protecting cap
Implementation Method 2
dewatering holes are formed, and a brim edge that protrudes from the upper surface... enabling to drain moisture that is collected in a blade portion
Implementation Method 3
guide elements thereof are formed with inclined surfaces for trimming hair

AI summary
A blade protecting cap (50) includes: a blade protecting cap main body (51) that protects a blade portion (14) in an event where the blade protecting cap (50) is installed to an electric razor (11); and a support portion (52) capable of mounting the electric razor (11), to which the blade protecting cap (50) is installed, in a predetermined state on a mounting surface in an event where the blade protecting cap (50) is allowed to abut against a mounting surface (100a). Then, a first opening (53) is formed in the blade protecting cap main body (51), and in a state where the support portion (52) is allowed to abut against the mounting surface (100a), and where the electric razor (11) to which the blade protecting cap (50) is installed is mounted in the predetermined state on the mounting surface (100a), the first opening (53) communicates with an outer space (S3) of the blade protecting cap (50).
