Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing shaving brushes require frequent contact with standard-sized pressurized shaving cream containers, leading to messy application and potential drying of cream in the brush, and solutions that attach a full-size container result in bulkiness and storage issues.

Innovation Solution

A shaving brush assembly with a passageway and sleeve designed to house a travel-size shaving cream container, allowing continuous dispensing of shaving cream directly to the bristles without needing to be in contact with a standard-sized container, providing a compact and convenient shaving experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a standard-sized pressurized shaving cream container is attached to the shaving brush, then continuous shaving cream supply is achieved, but the device becomes bulky and difficult to store

Engineering Contradiction:

Improvecontinuous shaving cream supplyVSAvoiddevice size

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The invention divides the shaving cream container into two separate components: a permanent small-capacity container integrated into the brush handle, and a detachable refillable container. This segmentation allows the brush to maintain a compact size while enabling continuous supply through periodic refilling of the small container, resolving the contradiction between continuous supply and compact size.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The small-capacity shaving cream container is nested within the brush handle structure, with the container fitting inside a recess or cavity in the handle. This nesting arrangement minimizes the overall device volume while maintaining the continuous supply capability, as the container is integrated into the handle rather than attached externally.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If the brush is repeatedly placed in contact with the container to receive shaving cream, then shaving cream can be applied, but the process becomes messy and time-consuming

Engineering Contradiction:

Improveshaving cream applicationVSAvoidfrequency of container contact

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The shaving cream is pre-loaded into the small container that is permanently integrated into the brush handle. This preliminary action eliminates the need for repeated contact with a large container during shaving, as the user can simply activate the dispensing mechanism on the brush itself. The refilling process is also simplified by designing the container to accept refill cartridges without requiring messy manual transfer.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If the backside of the brush is exposed to air, then the brush structure is simple, but shaving cream dries and blocks the passageway

Engineering Contradiction:

Improvebrush structureVSAvoidpassageway blockage

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The invention introduces a cap or cover that fits over the brush head or the container opening when not in use. This intermediary component seals the passageway and prevents air exposure, thereby preventing the shaving cream from drying and blocking the passageway. The cap is a simple addition that maintains structural simplicity while solving the blockage problem.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Reliability

If a large container is affixed to the brush, then continuous supply is ensured, but the device becomes tall and difficult to store

Engineering Contradiction:

Improveshaving cream supply continuityVSAvoiddevice height

Core Design Contradiction:

ReliabilityVSLength of stationary object

Solution Approach 1:

The invention segments the shaving cream supply system into a small permanent container integrated into the brush and a separate refillable container. The small container maintains a compact device height suitable for storage, while the segmentation allows the user to refill the small container from the larger refillable container, ensuring continuous supply without permanently attaching a large container to the brush.

Inventive Principle:

Principle #1Segmentation

AI summary

A shaving brush assembly includes a plurality of bristles, a base with a first side coupled to and supporting the plurality of bristles, a second side opposite the first side, and defining a passageway from the first side to the second side, the passageway dimensioned to receive at least a portion of a nozzle of a shaving cream container. The assembly also includes a sleeve coupled to and extending from the second side of the base, with the sleeve having an inner diameter less than an outer diameter of a standard-sized container of shaving cream.
