Heated Shaving Cream Dispenser with Integrated Handle and Stand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shaving cream heating devices often have exposed heated surfaces, are not ergonomically designed for standard can sizes, and can be expensive or difficult to use with proprietary cartridges, posing safety risks and usability issues.
Innovation Solution
A heated shave cream dispenser with a handle that integrates a heating element and a travel-sized aerosol canister, featuring a separable upper and lower portion with a brush and channel system for dispensing heated cream, and a stand for power supply, ensuring safe and ergonomic use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional heating devices heat the can or apply heat to a portion of the can, then the shaving cream can be heated, but exposed heated surfaces cause burn risks and safety hazards
Solution Approach 1:
The heating element is nested inside the handle structure, which in turn contains the canister. The handle acts as a protective enclosure that contains the heating element and directs heat to the canister through thermal contact, preventing exposed heated surfaces while maintaining effective heating.
Solution Approach 2:
The handle serves as an intermediary structure between the heating element and the canister. The heating element heats the handle, which then transfers heat to the canister through thermal contact, eliminating the need for exposed heated surfaces while still achieving the desired heating effect.
2Ease of operation
If clip-on type brush dispensers are used, then brush application is improved, but the can size becomes awkward for using as a brush handle
Solution Approach 1:
The device merges the brush applicator with the handle structure that contains the heating element and canister. This integration creates a unified device where the handle serves both as the structural support for heating and as the ergonomic grip for brush application, eliminating the need for separate clip-on components.
Solution Approach 2:
The handle is designed to serve multiple functions: it provides structural support for the canister, houses the heating element, facilitates heat transfer, and serves as the ergonomic grip for brush application. This multi-functionality eliminates the need for additional components while improving ease of operation.
3Length of moving object
If proprietary sized cartridges are used, then appropriate sizing is achieved, but the cartridges become expensive and difficult to acquire
Solution Approach 1:
The handle is designed with a universal interface that can accommodate different standard canister sizes. The retention member and channel system are configured to work with various canister dimensions, allowing the device to use commonly available over-the-counter canisters rather than proprietary cartridges, thereby improving adaptability and reducing cost.
Solution Approach 2:
The retention member is designed to dynamically adjust and secure canisters of different sizes. The mechanical retention feature allows the handle to adapt to various canister dimensions while maintaining secure holding and proper alignment with the channel, providing versatility across standard canister sizes.
4Adaptability or versatility
If standard size shaving cream canisters are used, then availability and cost are improved, but conventional heaters are not ergonomically designed for these can sizes
Solution Approach 1:
The handle is designed with universal compatibility for standard canister sizes found in over-the-counter products. The internal cavity and retention mechanisms are configured to accommodate various standard dimensions, allowing use of widely available canisters while maintaining ergonomic handle design for comfortable operation.
Solution Approach 2:
The handle dimensions and internal cavity are specifically designed to match the parameters of standard canister sizes. By adjusting the handle's internal geometry to correspond with common canister dimensions, the device achieves both ergonomic operation and compatibility with readily available products.

AI summary
A shaving cream dispenser and application device include a handle having an upper portion and a lower portion which form an internal cavity in which a travel sized shaving cream aerosol canister is placed. The canister includes a nozzle stem on the top that, when pressed towards the canister, opens an internal valve in the canister to release the shaving cream through the nozzle stem. The upper and lower portions of the handle are movably retained together, and a channel is provided at the top of the handle through which the shaving cream is dispensed into a brush or set of bristles at the top of the handle. The nozzle stem is actuated by pressing or moving the upper portion of the handle towards the lower portion. The lower portion of the handle further includes a heating element to heat the canister so that heated shaving cream can be dispensed. A stand is configured to hold the lower portion of the handle and provide electric power to the heating element in the lower portion of the handle.
