Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple parts are used to impart rigidity and flexibility to specific parts of a product, then the functional requirements are met, but the number of parts increases leading to increased manufacturing complexity and environmental load
Solution Approach 1:
The fiber structure implements local quality by creating distinct first regions with higher linear body density for rigidity and second regions with lower linear body density for flexibility. This allows different mechanical properties to be distributed throughout the structure without requiring separate components, thereby meeting functional requirements while reducing the number of parts.
Solution Approach 2:
The structure is segmented into multiple first regions arranged in a lattice pattern connected by second regions. This segmentation creates a modular design where each region can be optimized independently for specific mechanical properties, allowing the overall structure to achieve both rigidity and flexibility through internal differentiation rather than multiple separate parts.
2Adaptability or versatility
If multiple parts are used to combine different functional regions, then specific mechanical properties are achieved, but the number of manufacturing processes and materials increases
Solution Approach 1:
The invention merges multiple functional regions into a single integrated fiber structure. The first regions and second regions are formed as one continuous structure during the knitting process, eliminating the need for separate manufacturing steps for different components and reducing the complexity of assembly processes.
Solution Approach 2:
The manufacturing process utilizes parameter changes by varying the linear body density during knitting to create different regions with distinct mechanical properties. This allows the structure to achieve diverse functional characteristics through controlled variations in a single manufacturing process rather than requiring multiple specialized processes.
3Stability of the object's composition
If adhesive and sewing thread are used to combine parts, then the product structure is assembled, but the environmental load increases
Solution Approach 1:
The invention extracts and eliminates the need for adhesive and sewing thread by integrating all functional regions into a single knitted fiber structure. The lattice pattern of first regions connected by second regions is formed directly through knitting, removing harmful materials and simplifying the product composition for improved environmental sustainability.
