Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fastening elements are attached to edge profiles using tight fit, then reliability of attachment is improved, but ease of operation deteriorates due to difficulty in installation from dimensional variances and paint sagging
Solution Approach 1:
The fastening element changes its geometric parameters dynamically during installation. The arms are designed to be flexible or adjustable, allowing the fastening element to adapt its shape to accommodate dimensional variances in edge profiles and paint sagging, while still achieving a secure tight fit once installed
Solution Approach 2:
The fastening element incorporates dynamic characteristics through flexible arms that can bend or adjust during the installation process. This allows the element to accommodate variations in edge profile dimensions and paint surface irregularities, making installation easier while maintaining reliable attachment
2Strength
If fastening elements encircle edge profiles, then attachment strength is improved, but object-affected harmful factors worsen due to dust and dirt accumulation in gaps
Solution Approach 1:
The invention extracts the problematic gap between the fastening element and edge profile by designing the fastening element to attach to the side edge of the glass rather than encircling the edge profile. This eliminates the gap where dust and dirt would accumulate, while maintaining attachment strength through the side edge attachment mechanism
Solution Approach 2:
The fastening element transitions from a two-dimensional encirclement of the edge profile to a three-dimensional attachment at the side edge of the glass. This dimensional change allows the fastening element to avoid creating gaps while maintaining secure attachment through the side edge location
3Reliability
If fastening elements are made for tight fit, then reliability is improved, but device complexity increases due to difficulty in accommodating dimensional variances
Solution Approach 1:
The fastening element incorporates adjustable parameters in its arm structure, allowing it to adapt to dimensional variances in edge profiles. The arms can be bent, extended, or adjusted to accommodate different gap sizes and paint sagging, achieving reliable attachment without requiring multiple specialized fastening elements
Solution Approach 2:
The fastening element uses dynamic, flexible arms that can adapt their configuration during installation. This flexibility allows a single fastening element design to accommodate various dimensional variances and paint conditions, reducing device complexity while maintaining reliability
