Foam Dispensing Electric Shaver with Nested Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shavers lack a convenient and integrated system for dispensing shaving foam, requiring users to manually apply foam, which can be messy and inefficient.
Innovation Solution
A foam dispensing electric shaver with a handle body containing an inner compartment, a foam insert with a release nipple, and a pump system that allows for easy loading and dispensing of shaving foam, integrated with a rechargeable battery and motor-driven blades for efficient shaving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a foam dispensing system is integrated into the shaver, then convenience and efficiency of foam application is improved, but device complexity increases
Solution Approach 1:
The foam canister is nested within the handle body of the shaver, with the pump system integrated inside the same housing. The foam canister fits into a recessed cavity in the handle, and the pump mechanism is embedded within the handle structure, creating a compact nested arrangement that minimizes external complexity while providing automatic foam dispensing functionality.
2Device complexity
If manual foam application is used, then device complexity remains low, but mess and inefficiency increase
Solution Approach 1:
The pump system is designed to automatically dispense foam when the shaver is activated, eliminating the need for manual foam application. The motor-driven pump draws foam from the canister and delivers it through a nozzle directly to the shaving area, allowing the device to serve itself by automatically applying the necessary lubrication without user intervention or mess.
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
Enables convenient, mess-free shaving by automatically dispensing shaving foam and providing a motor-driven shaving experience with ergonomic design and rechargeable functionality.
Implementation Method 1
The foam dispenser has a pump coupled within the inner compartment adjacent the insert cavity and a spout coupled to the pump and extending through the front side of the handle body. The pump is in operational communication with the feed aperture to draw foam from the foam insert and release it through a distal end of the spout.
Implementation Method 2
A motor is coupled to the handle body within the inner compartment proximal the top side. The motor has a motor shaft extending through the neck to the head of the shaver. The motor shaft is in operational communication with the set of blades.
Implementation Method 3
A rechargeable battery is coupled to the handle body within the inner compartment adjacent the bottom side and is in operational communication with the dispense button and the power button.
