Solution Overview

Problem

Existing wet shaving razor systems face challenges in effectively venting and drying razor blade cartridges, as they often remain in a wet environment for an extended period due to inadequate design, leading to prolonged moisture exposure.

Innovation Solution

A container with a housing featuring storage spaces and a razor handle receiving opening, allowing the handle to project at an angle for drying, which also serves as a cost-effective razor stand, eliminating the need for a separate tray.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the razor blade cartridge is stored in a compartment with drain holes, then water can escape, but the venting is aggravated and the cartridge remains in a wet environment for a long time

Engineering Contradiction:
Improvemoisture exposureVSAvoiddrying time
Core Design Contradiction:
Object-affected harmful factorsVSDuration of action of stationary object

Solution Approach 1:

The patent introduces a new spatial dimension by providing access openings in the lower wall of the housing, allowing the razor handle to project downward outside the housing. This vertical projection creates an extended drying zone below the housing level, enabling airflow from multiple directions and significantly improving venting efficiency compared to traditional horizontal compartment arrangements.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent extracts the drying function from the enclosed compartment environment and relocates it to the external space below the housing. By allowing the razor handle to project outward through access openings in the lower wall, the wet blade cartridge is removed from the confined, moisture-trapping compartment and placed in an open environment with superior air circulation.

Inventive Principle:
Principle #2Taking out (Extraction)

2Object-affected harmful factors

If a separate razor tray is provided for drying, then venting is improved, but the system complexity and cost increase

Engineering Contradiction:
Improvemoisture exposureVSAvoidsystem structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent makes the container housing multi-functional by integrating both storage and drying functions into a single component. The housing not only stores multiple razor blade cartridges in its compartments but also serves as a razor stand through its access openings in the lower wall, eliminating the need for a separate drying tray and reducing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the storage function and drying function into a single integrated housing structure. The container that holds the blade cartridges also provides the structural framework for the drying stand, combining what were previously separate functions (storage container + drying tray) into one unified component.

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If the razor handle is placed horizontally on the tray, then it is stable, but the venting of the blade cartridge is reduced

Engineering Contradiction:
Improverazor stabilityVSAvoidmoisture exposure
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The patent changes the spatial arrangement from a horizontal placement on a flat surface to a vertical projection through access openings in the lower wall. This vertical orientation allows the razor handle to extend downward, creating a stable supported position while simultaneously maximizing exposure to air flow from above and around the blade cartridge, thereby improving venting while maintaining stability.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
