Solution Overview

Problem

Solid compositions do not adhere strongly to surfaces, leading to dislocation or loosening during shipment or handling, which complicates reconstitution and affects assay performance.

Innovation Solution

Plasma treatment of surfaces to increase their adhesion to solid compositions, such as lyophilized pellets, by enhancing surface hydrophilicity and wettability, thereby improving the interaction between the composition and the surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If solid compositions are placed on untreated surfaces, then the surface is easier to manufacture and handle, but the adhesion strength is insufficient causing dislocation during shipment and handling

Engineering Contradiction:
Improveadhesion strengthVSAvoidsurface treatment complexity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The surface is plasma-treated in advance before the solid composition is applied. This preliminary action modifies the surface properties (increases hydrophilicity and wettability) so that when the composition is later applied and dried, it forms strong adhesion to the surface, preventing dislocation during shipment and handling.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If plasma treatment is applied to the surface, then adhesion strength is improved, but the manufacturing process becomes more complex

Engineering Contradiction:
Improveadhesion reliabilityVSAvoidsurface treatment process
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Plasma treatment changes the physical and chemical parameters of the surface, specifically increasing its hydrophilicity and wettability. These parameter changes enable the solid composition to adhere more reliably to the surface, preventing dislocation and ensuring complete reconstitution, thereby improving adhesion reliability.
