Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hydraulic clamping device is used to lock the second milling device, then the milling device can be positioned without play in the operating position, but the structural configuration becomes complex and costs increase
Solution Approach 1:
The patent replaces the hydraulic clamping device with a centrifugal locking mechanism that uses centrifugal force generated during rotation to lock the second milling device in position. This mechanical substitution eliminates complex hydraulic systems while achieving reliable positioning without play during the machining process.
Solution Approach 2:
The locking mechanism transitions from a static hydraulic system to a dynamic centrifugal system that automatically engages and disengages based on rotational speed. During rotation, centrifugal force locks the milling device; during idle periods, the mechanism releases, enabling automatic positioning without complex control systems.
2Reliability
If a hydraulic clamping device is used to lock the second milling device, then the milling device can be positioned without play, but operational costs increase
Solution Approach 1:
The patent employs a simple mechanical centrifugal locking mechanism with basic components such as centrifugal elements, guide surfaces, and locking surfaces. This approach replaces expensive hydraulic systems with affordable mechanical parts, significantly reducing manufacturing costs while maintaining positioning accuracy.
3Adaptability or versatility
If the second milling device is axially movable between use and non-use positions, then flexible multi-profile machining is enabled, but positioning precision during rotation may be compromised
Solution Approach 1:
The patent implements a dynamic locking mechanism that automatically engages during rotation to maintain positioning precision. The centrifugal elements engage with guide surfaces at specific rotational speeds, ensuring the second milling device is securely locked in the required position during machining while allowing free movement during idle periods for profile switching.
Solution Approach 2:
The locking function is extracted as a separate centrifugal mechanism distinct from the axial movement mechanism. This separation allows the second milling device to move freely axially for profile changes while the centrifugal locking system independently ensures precise positioning during rotation, resolving the conflict between flexibility and precision.
