Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If metallic wire counterparts are used for hook-and-loop closures, then mounting properties are achieved, but production becomes expensive and elaborate
Solution Approach 1:
The patent replaces expensive metallic wire counterparts with inexpensive plastic counterparts that can be easily manufactured through injection molding. The plastic material, while less durable than metal, provides sufficient mounting properties for the intended application while dramatically reducing production costs and complexity.
Solution Approach 2:
The invention changes the material parameter from metal to plastic, and modifies the structural parameters of the counterpart (integrating mounting protrusions directly into the closure body). This parameter change achieves the desired mounting functionality while eliminating the complexity of metal wire production.
2Reliability
If metallic scrim is used as counterpart, then mounting function is provided, but the scrim tends to fray and loops break, reducing durability
Solution Approach 1:
The patent uses plastic material with added fibreglass strands to create a composite counterpart that combines the ease of plastic manufacturing with the strength and durability of fibreglass. This composite structure prevents fraying and breaking while maintaining the mounting function.
Solution Approach 2:
The counterpart is designed with discrete mounting protrusions integrated into the closure body, replacing the continuous metallic scrim structure. This segmentation into individual plastic elements with embedded fibreglass reinforcement eliminates the fraying issue inherent in continuous metal scrims.
3Reliability
If perforated metal sheets are used as counterparts, then mounting protrusions can be fixed, but only in a distinct orientation, restricting applicability
Solution Approach 1:
The plastic counterpart is designed with multiple mounting protrusions arranged in different orientations within the same closure body. This allows the single counterpart to accommodate mounting surfaces oriented in various directions, making it universally applicable to different mounting scenarios without requiring orientation-specific designs.
Solution Approach 2:
Different regions of the plastic counterpart contain mounting protrusions with different spatial orientations and configurations. This local variation in protrusion orientation allows the counterpart to adapt to mounting surfaces at various angles, providing orientation flexibility while maintaining secure fixation.
4Reliability
If metal wire counterparts are used, then mounting properties are achieved, but the production is expensive and elaborate
Solution Approach 1:
The patent replaces the mechanical process of metal wire forming and assembly with an injection molding process that directly creates the plastic counterpart with integrated mounting protrusions. This substitution of manufacturing methodology dramatically improves production efficiency by creating the entire component in a single molding operation.
Solution Approach 2:
The invention merges the closure body and mounting protrusions into a single integrated plastic counterpart component. This consolidation eliminates the need for separate metal wire components and multiple assembly steps, thereby improving production efficiency and reducing manufacturing complexity.

AI summary
A mounting device with one metallic base plate, from which a plurality of mounting eyelets protrude. The mounting device is obtainable by incising a plurality of arc-shaped eyelet blanks while leaving two connection sections per eyelet blank into the surface of the base plate and production of the mounting eyelets by bending the eyelet blanks out of the base plate around a bending edge in the area of the connection sections. At least part of the eyelet blanks are arranged as groups of eyelet blanks with the latter being nested to each other. Preferably, the groups of eyelet blanks are arranged rotated relative to each other.
