Integrated Razor Handle Dispenser for Travel Convenience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safety razors require separate containers for shave cream or gel, which are inconvenient for travel due to bulkiness and airline restrictions, and often result in rust stains from exposure to moisture.
Innovation Solution
A disposable safety razor with a built-in shaving conditioning compound dispenser, where the handle contains a pressure cavity and valve system that allows for downward dispensing of shave cream or gel when held upright, using a sliding button or pivotable lever actuator to release the product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate container for shaving cream is used, then the shaving function is complete, but the device becomes bulky and inconvenient for travel
Solution Approach 1:
The patent combines the razor and shaving cream dispenser into a single integrated device. The shaving cream container is positioned within the handle of the razor, merging two previously separate items (razor and shaving cream can) into one unified tool, thereby reducing the overall volume and eliminating the need to carry multiple separate containers during travel
2Productivity
If a metal shave cream container is used, then the shaving cream can be dispensed effectively, but rust stains are created on storage surfaces
Solution Approach 1:
The patent employs a composite construction where the shaving cream container is formed from rust-proof materials such as plastic or coated metal. This composite material approach maintains the structural integrity and dispensing functionality of the container while eliminating the rusting problem associated with plain metal containers, thereby preventing harmful rust stains on storage surfaces
3Productivity
If the razor is inverted to dispense shaving cream from an integrated dispenser, then the shaving cream can be dispensed, but the operation becomes awkward and clumsy
Solution Approach 1:
Instead of inverting the entire razor to dispense shaving cream, the patent positions the dispensing mechanism at the bottom of the handle and activates it in the upright position. The user presses a button or actuator at the bottom of the handle, which opens a valve to dispense shaving cream downward onto the hand or directly onto the skin, eliminating the need to invert the razor and maintaining ergonomic operation throughout
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
This design minimizes storage space requirements, prevents rust stains, and allows for convenient, ergonomic dispensing of shave products during travel, eliminating the need for a separate container.
Implementation Method 1

Data Source
AI summary
A disposable safety razor having an integral shaving conditioner dispenser includes a neck to which a blade cartridge is affixed at a top end thereof and a handle extends downwardly therefrom. The handle is ergonomically shaped and has an exterior wall that defines a pressure cavity therein for receiving a shaving conditioning compound and a pressurized dispensing gas. The handle has an opening at its bottom and a valve received in the opening. The valve is configured to dispense the shaving conditioning compound downwardly through the valve with the razor held upright. A dispensing cap covers the valve and is engaged therewith such that movement of the dispensing cap causes release of the shaving conditioning compound downwardly through the valve and out from a discharge opening in the cap while holding the razor upright with the blade cartridge and neck positioned higher than the handle bottom and dispensing cap.
