Pressure-Responsive Phase-Change Razor Cooling Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional razors often cause skin irritations and discomfort during shaving due to direct blade contact, leading to issues like redness, burning, and increased warmth, which existing solutions like lubricating strips and electric cooling systems fail to adequately address, especially due to increased costs and complexity.
Innovation Solution
A razor component featuring a pressure-responsive phase-change component coupled to a cooling element that provides a cooling effect on the skin by initiating phase changes in response to applied pressure, reducing skin irritations and discomfort without the need for an electrically powered cooling system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If an electrically powered cooling system is integrated into the razor, then the cooling effect on skin is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent replaces the electrically powered cooling system (mechanical/electrical system) with a chemically powered cooling system using endothermic reactions. The cooling element contains reactants that undergo an endothermic chemical reaction when activated, absorbing heat from the skin without requiring electrical power, motors, or complex control systems.
Solution Approach 2:
The patent changes the operating principle of the cooling system from electrical/mechanical to chemical. Instead of using electric motors, compressors, or Peltier elements, the system uses endothermic chemical reactions (change in chemical parameters) to generate cooling effects, thereby simplifying the device architecture.
2Productivity
If conventional razors with direct blade contact are used, then the shaving function is achieved, but skin irritations and discomfort increase
Solution Approach 1:
The patent applies preliminary anti-action by implementing a cooling element that actively counteracts the heat and irritation generated by blade contact before the irritation can fully develop. The endothermic cooling reaction is activated during shaving to preemptively reduce skin temperature and prevent inflammation, redness, and discomfort associated with direct blade contact.
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
The solution effectively reduces skin irritations and discomfort during shaving by actively cooling the skin, limiting blood flow and warmth, while being cost-effective and environmentally friendly, as it eliminates the need for electrical components and complex designs.
Implementation Method 1
