Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional textile fabrics are cut, then the fabric can be shaped and processed, but the cutting edges become unraveled and require sewing
Solution Approach 1:
The film layer is applied to the fabric surface before cutting, forming a protective coating that prevents unraveling at the cutting edges. This preliminary protective action eliminates the need for subsequent sewing operations to secure the edges.
Solution Approach 2:
A thin film layer is deposited on the fabric surface, creating a flexible protective shell that conforms to the fabric structure. This film layer reinforces the fabric at cut edges, preventing yarn separation while maintaining the fabric's flexibility and drape.
2Adaptability or versatility
If multiple yarns are changed during manufacturing to create patterns, then design variety is achieved, but the process becomes time-consuming and complicated
Solution Approach 1:
The film layer is applied in different colors to the fabric surface, creating various patterns and designs. This approach achieves design variety without requiring changes to the underlying yarn composition or weaving structure, significantly simplifying the manufacturing process.
Solution Approach 2:
The invention moves pattern creation from the structural dimension (changing yarns during weaving) to the surface dimension (applying colored film layers). This dimensional shift allows patterns to be applied post-manufacturing or during finishing, decoupling design complexity from manufacturing complexity.
3Ease of manufacture
If the fabric structure is simplified for easy processing, then processing ease improves, but toughness and structural strength may be compromised
Solution Approach 1:
The invention creates a composite structure combining the base fabric with a film layer. The film layer acts as a reinforcement that enhances toughness and prevents unraveling, while the overall structure remains simple enough for easy processing. The composite nature allows each component to contribute its strengths.

AI summary
A textile fabric is provided, including: a main body and a first film layer. The main body includes two surfaces opposite to each other and at least one hollow hole penetrating through the two surfaces. The first film layer is disposed on one of the two surfaces and covers the at least one hollow hole. Therefore, a shape of the at least one hollow hole is changeable to meet different design requirements, and the first film layer can fix the at least one hollow hole and prevent edges of the main body at the at least one hollow hole from becoming unraveled so that the textile fabric has a three-dimensional surface texture and is tough and easy to be processed.
