Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If lipophilic substances or polymers are used for skin permeation, then skin permeation efficiency is improved, but side effects and toxicity occur
Solution Approach 1:
The patent uses a peptide carrier (intermediary) that facilitates the transport of bioactive materials across the skin barrier. The peptide acts as a mediator between the bioactive material and the skin barrier, enabling permeation without requiring lipophilic substances or polymers that cause toxicity. The peptide carrier system allows hydrophilic bioactive materials to cross the lipophilic stratum corneum barrier safely.
Solution Approach 2:
The patent changes the molecular parameters of the carrier system by using peptides with specific amino acid sequences and structures. This parameter change allows the carrier to interact with both the hydrophilic bioactive material and the lipophilic skin barrier, achieving efficient permeation through modified molecular properties rather than relying on traditional lipophilic substances.
2Productivity
If physical delivery systems such as microneedles are used, then delivery effectiveness is improved, but irreversible skin damage occurs
Solution Approach 1:
The peptide carrier serves as a non-invasive intermediary that enables bioactive material delivery through the intact skin barrier via molecular recognition and transport mechanisms. This eliminates the need for physical penetration methods like microneedles that cause irreversible damage, achieving effective delivery through biochemical interaction rather than mechanical disruption.
Solution Approach 2:
The patent replaces the mechanical delivery system (microneedles) with a biochemical delivery system (peptide carrier). Instead of physically piercing the skin to deliver materials, the system uses molecular recognition, binding, and transport mechanisms to deliver bioactive materials through the skin barrier, eliminating mechanical damage while maintaining delivery effectiveness.
3Ease of operation
If low-molecular-weight substances are used, then skin permeation is enabled, but permeation efficiency remains low
Solution Approach 1:
The patent creates a composite delivery system combining the peptide carrier with the bioactive material. This composite structure leverages the permeation capabilities of the peptide while delivering the bioactive payload, achieving both permeation capability and high efficiency. The composite approach allows optimization of both components to work synergistically.
Solution Approach 2:
The peptide carrier acts as an intermediary that bridges the gap between the bioactive material and the skin barrier. It facilitates efficient permeation by mediating the interaction between the material and barrier, overcoming the low efficiency problem of simple low-molecular-weight substances through its specialized transport function.
