Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a water jet bar with nozzles arranged perpendicular to the machine direction is used to bond fiber web, then bonding of the fiber structure is achieved, but flexibility in bonding location and design possibilities are limited
Solution Approach 1:
The patent applies the dynamics principle by replacing the static water jet bar with a movable fluid jet head that can be positioned in at least two spatial directions relative to the fiber structure. This allows the bonding location to be dynamically adjusted according to design requirements, enabling selective bonding of specific areas while maintaining operational flexibility.
Solution Approach 2:
The fluid jet head serves multiple functions: it can bond fiber structures selectively in different areas, create various patterns and lettering, and accommodate different fiber structure configurations (flat or three-dimensionally shaped). This multi-functionality resolves the contradiction by providing bonding flexibility without requiring multiple specialized devices.
2Loss of substance
If the entire fiber structure is bonded using a water jet bar, then complete bonding is achieved, but material economy is reduced and edge areas cannot be reused
Solution Approach 1:
The patent implements local quality by enabling selective bonding of only specific areas of the fiber structure through precise positioning of the fluid jet head. This allows edge areas and non-critical regions to remain unbonded or lightly bonded, reducing material waste while maintaining structural integrity where bonding is applied. The localized bonding approach preserves material economy without compromising the necessary bonding precision in critical areas.
3Adaptability or versatility
If a fluid jet head on a manipulator is used for selective bonding, then design flexibility and material economy are improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the bonding function into a movable fluid jet head system that can independently position and bond specific areas. This segmentation allows selective bonding operations without requiring complex reconfiguration of the entire bonding system, reducing the operational complexity despite the added mobility capability.
