Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fastening elements are formed directly on a preexisting substrate, then processing and handling steps are eliminated and design control is improved, but flexibility in design and material efficiency are limited
Solution Approach 1:
The fastening component is divided into multiple discrete fastening elements that can be independently formed from different layers. Each fastening element can have varied properties, materials, and configurations while being part of the overall fastening system, enabling design flexibility without requiring separate processing steps for each element.
Solution Approach 2:
The fastening component utilizes composite construction where fastening elements are formed from multiple layers including a substrate layer and a fastening material layer. This allows different regions of the fastening component to have different material properties, enabling both ease of manufacture and design flexibility simultaneously.
2Adaptability or versatility
If discrete fastening material strips or patches are used, then design flexibility and material choice are improved, but additional processing and handling steps are required
Solution Approach 1:
The fastening elements are merged with the article component layers during the same manufacturing process. The fastening component is formed by combining a substrate layer with fastening material layers in a single integrated process, eliminating the need for separate processing and handling steps while maintaining design flexibility.
Solution Approach 2:
The fastening component serves multiple functions simultaneously: it provides the fastening elements for securing the article, acts as a structural component of the article itself, and enables design customization. This multi-functionality eliminates the need for separate discrete fastening material application steps.
3Reliability
If more fastening elements are used to ensure secure fastening, then fastening performance is improved, but material consumption and cost increase
Solution Approach 1:
Different regions of the fastening component have different properties optimized for their specific functions. The fastening elements are strategically positioned and sized to provide adequate fastening performance only where needed, rather than uniformly distributing material throughout the entire component, thus reducing overall material consumption while maintaining reliability.
Solution Approach 2:
The fastening system uses a controlled number of fastening elements that provide sufficient performance without excessive material usage. The design optimizes the quantity and distribution of fastening elements to achieve the minimum necessary for reliable fastening, avoiding waste of material while ensuring adequate performance.
