Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional multilayer structured cloths are used, then basic fabric structure is achieved, but lightweight properties for bulkiness and soft texture are insufficient
Solution Approach 1:
The patent applies parameter changes by specifying precise torque values (30 T/m or less) and fiber fineness ranges (0.00002 to 2.0 dtex single fiber, 40 to 180 dtex total) to achieve the desired balance between bulkiness/soft texture and lightweight properties. This quantitative parameter optimization resolves the contradiction by defining exact material specifications that simultaneously satisfy both requirements.
Solution Approach 2:
The patent employs composite materials through the use of crimped fibers combined with spun yarns in a multilayer structure. The crimped fiber component provides bulkiness and soft texture, while the overall multilayer construction maintains lightweight properties. This composite approach allows the fabric to achieve superior bulkiness and softness without proportionally increasing weight.
2Strength
If conventional multilayer structured cloths are used, then basic fabric structure is achieved, but cushioning properties are insufficient
Solution Approach 1:
The patent optimizes cushioning properties through parameter changes in fiber specification, particularly torque (30 T/m or less) and crimp characteristics. These parameter adjustments enhance the fabric's ability to absorb and distribute pressure, improving cushioning performance without requiring complex structural modifications beyond the established multilayer configuration.
Solution Approach 2:
The patent applies local quality by incorporating crimped fibers specifically in the ground structure portions where cushioning is most needed, while maintaining different yarn compositions in connecting and insert positions. This localized optimization of fiber properties enhances cushioning properties in critical areas without unnecessarily complicating the overall fabric structure.
3Reliability
If conventional multilayer structured cloths are used, then basic fabric structure is achieved, but sweat absorbing and quick drying properties are insufficient
Solution Approach 1:
The patent improves sweat absorbing and quick drying properties through parameter changes in fiber selection and fabric construction. The specification of crimped fibers with particular torque values and fineness, combined with the multilayer structure, creates capillary channels that enhance moisture wicking and evaporation efficiency, achieving superior sweat management without excessive structural complexity.
4Stability of the object's composition
If crimped fiber with high torque is used, then yarn structure is achieved, but surface friction increases
Solution Approach 1:
The patent resolves this contradiction through precise parameter control, specifying torque of 30 T/m or less for crimped fibers. This parameter threshold maintains sufficient yarn structure stability while limiting surface friction to acceptable levels. The patent further refines this by specifying single fiber fineness of 0.00002 to 2.0 dtex and total fineness of 40 to 180 dtex, optimizing the balance between structural integrity and surface smoothness.
