Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional coolant compositions are used, then cooling effect is provided, but significant re-engineering effort is required for different application areas
Solution Approach 1:
The coolant composition is formulated with a universal base of glycerol, menthol, calcium hydroxide, barium hydroxide, and water that can be safely applied across multiple application areas including personal care, medical, and industrial uses without requiring significant re-engineering. The composition maintains effective cooling properties while being safe for contact with skin and suitable for diverse packaging formats.
2Reliability
If coolant composition is formulated for specific applications, then effectiveness is improved, but versatility across application areas is reduced
Solution Approach 1:
The coolant composition maintains consistent effective parameters across applications through controlled concentrations of key ingredients: 0.1-5% menthol for cooling sensation, 5-50% glycerol for viscosity and skin compatibility, and 0.01-1% each of calcium hydroxide and barium hydroxide for pH stabilization. These parameter ranges ensure reliable cooling effectiveness while allowing adaptation to different application areas and packaging formats.
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 coolant composition can be used in a plurality of applications without significant re-design, providing effective cooling properties and extended duration of action through its adaptable form and packaging, suitable for diverse technical applications including clothing, bedding, and medical products.
Implementation Method 1
Menthol's ability to chemically trigger the cold-sensitive TRPM8 receptors in the skin is responsible for the cooling sensation that it provokes when inhaled, eaten, or applied to the skin.
Implementation Method 2
U.S. Pat. No. 6,146,546 discloses a freezable coolant composition used for cold-preservation of foods by utilizing the latent heat of fusion at the freezing point
