Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional components and plastic-based materials are used to manage friction, then friction control is improved, but device complexity and sustainability are worsened
Solution Approach 1:
The patent combines the friction control function directly into the housing cover and blade platform surfaces by forming textured patterns (grooves, dimples, or raised features) during the manufacturing process. This eliminates the need for separate friction management components such as elastomeric materials or lubricating material applications, thereby reducing device complexity while maintaining effective friction control.
Solution Approach 2:
The patent changes the surface parameters of the housing cover and blade platform by forming textured patterns with specific geometric characteristics (groove depths of 10-100 μm, dimple diameters of 20-100 μm, or raised feature heights of 10-100 μm). These parameter changes modify the surface properties to control friction directly, replacing the need for additional plastic-based friction management components.
2Reliability
If additional components and plastic-based materials are used to manage friction, then friction control is improved, but manufacturing cost is worsened
Solution Approach 1:
The friction control function is merged into the existing housing cover and blade platform manufacturing process. By forming textured surfaces (grooves, dimples, or raised features) during the same manufacturing cycle, the patent eliminates the need for separate components and additional manufacturing steps, thereby reducing overall manufacturing cost while maintaining effective friction control.
Solution Approach 2:
The patent modifies surface parameters (depth, diameter, height, spacing) of the housing cover and blade platform during manufacturing to achieve friction control. These parameter changes are integrated into the existing manufacturing process, avoiding the need for additional components and associated manufacturing costs.
3Reliability
If plastic-based materials are used to manage friction, then friction control is improved, but sustainability is worsened
Solution Approach 1:
The patent changes the surface parameters of metal or alternative sustainable materials by forming textured patterns (grooves, dimples, or raised features) with controlled dimensions. This approach achieves friction control without relying on plastic-based materials, thereby improving sustainability while maintaining effective friction management.
