Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the content of electrically conductive fiber is kept low (0.01%-5% by mass) to maintain antistatic properties, then the glove can prevent electrical shocks and short circuits, but the electrical conductivity fluctuates significantly due to abrasion and durability is reduced
Solution Approach 1:
The patent uses composite yarn structure where electrically conductive yarn is wrapped around a core yarn. This composite structure allows the conductive yarn to be protected by the core yarn from abrasion, while still maintaining the desired electrical conductivity through the conductive outer layer. The combination of conductive and non-conductive materials in specific proportions achieves both electrical stability and durability.
Solution Approach 2:
The patent applies different yarn compositions to different parts of the glove. Specifically, the palm area (which experiences most abrasion) uses a higher proportion of electrically conductive yarn (5-20%) compared to other areas (0.01-5%). This local variation ensures that the most worn areas maintain electrical conductivity while other areas provide overall protection, resolving the contradiction between conductivity stability and durability.
2Reliability
If the content of electrically conductive fiber is increased to ensure stable electrical conductivity, then abrasion resistance improves, but the risk of electrical shock and short circuit increases
Solution Approach 1:
The patent precisely controls the parameters of electrically conductive fiber content (0.01-5% in most areas, 5-20% in palm area) and core yarn elongation rate (no greater than 3%). By optimizing these parameters, the glove achieves sufficient electrical conductivity for safety while preventing excessive conductivity that would cause electrical shocks or short circuits. The core yarn's low elongation rate ensures the conductive yarn remains positioned to provide stable conductivity without becoming too conductive.
3Reliability
If electrically conductive yarn is exposed on the surface to maintain conductivity, then electrical function is achieved, but abrasion of the conductive yarn occurs leading to conductivity loss
Solution Approach 1:
The patent implements a nested structure where the electrically conductive yarn is wrapped around a core yarn. The core yarn acts as a protective inner layer that shields the conductive yarn from direct abrasion with external objects. This nested configuration allows the conductive yarn to remain exposed enough to provide electrical function while being protected by the core yarn, thereby maintaining both conductivity and durability throughout the glove's service life.
