Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If copper cysteamine nanoparticles are used in photodynamic therapy, then cancer cells can be targeted and destroyed through reactive oxygen species production, but the nanoparticles are not efficiently activated to produce sufficient reactive oxygen species for effective cell death
Solution Approach 1:
The patent changes the activation parameter from conventional light sources to microwave radiation, which fundamentally alters the energy interaction mechanism with copper cysteamine nanoparticles. This parameter change enables efficient generation of reactive oxygen species that was not achieved with traditional photodynamic therapy light sources, directly resolving the contradiction between nanoparticle activation efficiency and cancer cell destruction effectiveness
Solution Approach 2:
The patent substitutes the conventional optical activation mechanism with a microwave-based activation system. This replacement of the activation mechanism enables the copper cysteamine nanoparticles to produce sufficient reactive oxygen species for effective cancer cell destruction, overcoming the limitation of inefficient activation in traditional photodynamic therapy
