Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional textile structures are used, then manufacturing simplicity is maintained, but moisture transmission capability is insufficient leading to discomfort and thermal insulation degradation
Solution Approach 1:
The patent applies composite materials by combining multiple yarn types (thermoregulating yarns with phase change materials, moisture-wicking yarns, insulating yarns) into a single textile structure. This composite approach enables the fabric to simultaneously perform moisture transmission, thermal regulation, and insulation functions that traditional single-material textiles cannot achieve, directly resolving the contradiction between reliability and structural complexity.
Solution Approach 2:
The textile structure is segmented into functional zones with different yarn compositions and densities. The patent divides the fabric into regions with varying proportions of thermoregulating, moisture-wicking, and insulating yarns to optimize performance in different areas, allowing complex functionality to be achieved through modular design rather than uniform complexity throughout.
2Reliability
If textile structures are designed for high moisture transmission, then comfort is improved, but thermal insulation degrades due to moisture build-up
Solution Approach 1:
The patent employs dynamic thermal regulation through phase change materials embedded in thermoregulating yarns that automatically adjust to temperature conditions. These materials absorb excess heat when the body is hot and release stored heat when cold, creating a dynamic response that maintains both comfort and thermal insulation without requiring active control systems.
Solution Approach 2:
The textile structure utilizes parameter changes in the phase change materials' thermal properties at specific temperature thresholds. The materials undergo phase transitions that alter their heat capacity and thermal conductivity, enabling the fabric to adaptively maintain optimal thermal insulation while permitting moisture transmission, thus resolving the contradiction between comfort and temperature control.
3Duration of action of stationary object
If durable coating is applied to textile structure, then wash durability is improved, but moisture management capability may be compromised
Solution Approach 1:
The patent applies durable coating selectively to specific zones of the textile structure rather than uniformly across the entire fabric. By localizing the coating application to areas where durability is most needed while leaving moisture-critical zones uncoated or lightly coated, the invention maintains wash durability without compromising moisture management capability in functional areas.
Solution Approach 2:
The patent uses binder materials as intermediaries between the durable coating and the textile fibers. These binders are specifically selected to be compatible with both the coating formulation and the fiber types, ensuring strong adhesion and durability while maintaining the fabric's inherent moisture transmission and thermal regulation properties. The intermediary binder prevents the coating from blocking moisture pathways.

AI summary
A textile structure including one or more layers of warp yarns interwoven with one or more layers of weft yarns, a durable thermoregulating coating, and a binder that chemically bonds the durable thermoregulating coating to the textile structure. The warp yarns and/or weft yarns include polyester yarns. A method for manufacturing a textile structure includes weaving one or more layers of warp yarns with one or more layers or weft yarns to form a woven textile structure, brushing the textile structure at least two times, applying a binder to the textile structure, and applying a durable thermoregulating coating to the textile structure such that the binder chemically bonds the durable thermoregulating coating to the textile structure. The method may also include heat setting and curing the textile structure to fix the durable thermoregulating coating permanently onto the textile structure.
