Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-textile polymeric outer layer is used for oil resistance and liquid repellency, then chemical resistance is improved, but electrical conductivity cannot be precisely controlled
Solution Approach 1:
The patent combines polymeric outer layer material with electrically conductive particles to create a composite coating that simultaneously provides chemical resistance and controllable electrical conductivity. The conductive particles are dispersed within the polymeric matrix, allowing the outer layer to function both as a chemical barrier and an electrical pathway.
Solution Approach 2:
The patent controls electrical conductivity by varying parameters such as the concentration, size, and distribution of conductive particles within the polymeric outer layer. By adjusting these parameters during the coating process, precise control over the electrical resistance of the glove is achieved while maintaining chemical resistance properties.
2Reliability
If conductive particles are incorporated into the outer layer, then electrical conductivity is improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the application of the polymeric outer layer and the incorporation of conductive particles into a single coating step. The conductive particles are mixed with the polymeric coating material before application, eliminating the need for separate steps to apply the coating and add conductivity, thus simplifying the manufacturing process.
Solution Approach 2:
The polymeric outer layer serves multiple functions simultaneously: it provides chemical resistance, liquid repellency, tactile sensitivity, and electrical conductivity. This multi-functionality reduces the need for additional layers or components, simplifying the overall glove structure and manufacturing process.
