Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a tool holder is designed for high-speed rotation, then productivity is improved, but precision adjustment of mass balance and runout becomes difficult
Solution Approach 1:
The patent enables preliminary adjustment of mass balance and runout amount before high-speed machining operations. By providing adjustment mechanisms that can be configured prior to operation, the system allows precision setup to be completed while the tool holder is stationary, ensuring optimal performance during subsequent high-speed rotation without compromising adjustment precision.
Solution Approach 2:
The flange structure incorporates elastic deformation capability that allows dynamic adjustment of runout amount through controlled clamping forces. This dynamic adjustment mechanism enables precise runout correction by deforming the flange elastically under screw clamping, providing fine-tuning capability that maintains precision even when preparing for high-speed operations where minimal runout is critical.
2Stability of the object's composition
If the flange structure is made rigid for stability, then rotational stability is improved, but runout amount adjustment capability is reduced
Solution Approach 1:
The patent utilizes elastic deformation of the flange structure to enable runout amount adjustment. By applying controlled clamping forces through screws, the flange's physical state is temporarily changed within its elastic range, allowing runout correction. After adjustment, the flange returns to its stable configuration, maintaining rotational stability during operation. This parameter change approach resolves the contradiction by allowing temporary flexibility for adjustment while preserving overall structural stability.
Solution Approach 2:
The flange structure is designed with controlled elasticity that allows dynamic adjustment of runout through screw clamping forces. The structure transitions between a rigid stable state during rotation and a slightly deformed state during adjustment, enabling runout correction without compromising the overall rotational stability required for high-speed machining.
