Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sunscreen and protective clothing are used, then skin protection from radiation is provided, but the protection is temporary and requires repeated application
Solution Approach 1:
The patent applies preliminary action by creating permanent or long-lasting micro-disruptions in the skin structure before the need for ongoing protection. These disruptions are formed using laser or other energy sources to establish a permanent structural modification that provides continuous protection without requiring repeated application of external agents like sunscreen.
Solution Approach 2:
The patent replaces the mechanical system of repeatedly applying and removing sunscreen and protective clothing with a permanent structural modification of the skin itself. The micro-disruptions created in the skin structure provide lasting protection through a one-time procedure rather than continuous external application.
2Reliability
If external insulation methods like clothing and oils are used, then thermal protection is provided, but the insulation is external and can be removed by environmental influences
Solution Approach 1:
The patent creates permanent structural modifications in the skin through micro-disruptions that provide intrinsic thermal insulation properties. This preliminary structural change ensures that the insulation is built into the skin itself rather than being an external layer that can be removed by environmental factors.
Solution Approach 2:
The patent changes the physical parameters of the skin structure by creating micro-disruptions that alter thermal conduction properties. These structural changes provide permanent thermal insulation by modifying the skin's intrinsic properties rather than relying on external protective layers.
3Ease of manufacture
If conventional tanning methods are used, then skin color modification is achieved, but the methods are temporary and carry health hazards
Solution Approach 1:
The patent replaces conventional tanning methods with laser-induced micro-disruptions that create permanent structural modifications in the skin. This substitution eliminates the need for repeated exposure to harmful UV radiation while achieving long-lasting skin color and texture changes through controlled structural alteration.
Solution Approach 2:
The patent converts the harmful effect of laser energy into a beneficial permanent structural modification. By using controlled laser-induced micro-disruptions, the patent achieves lasting skin color and texture changes without the health hazards associated with conventional tanning methods.
4Reliability
If ultrashort pulse lasers are used to create micro-disruptions, then long-lasting protection and cosmetic effects are achieved, but the process creates subsurface damage
Solution Approach 1:
The patent carefully controls the parameters of the laser treatment to create micro-disruptions that provide long-lasting protection while minimizing damage. By adjusting pulse duration, energy levels, and treatment depth, the patent achieves permanent structural modifications without excessive subsurface damage.
Solution Approach 2:
The patent applies local quality by creating specific micro-disruptions at controlled depths and locations within the skin. The laser energy is focused to create precise structural modifications in targeted areas while preserving the integrity of surrounding tissue, thus providing protection without widespread damage.
