Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a small inclined surface interface is used for the tool carrier holder connection, then the tool carrier can be easily replaced, but positional stability and vibration resistance deteriorate
Solution Approach 1:
The patent transitions from a small inclined surface contact (2D plane) to a conical contact surface (3D geometry with radial extension). This dimensional change increases the contact area from a limited inclined plane to a conical surface that extends radially outward, providing both ease of tool replacement and enhanced positional stability through increased contact area and geometric constraint.
Solution Approach 2:
The patent employs a conical contact surface with a specified half-opening angle (5° to 30°) instead of a flat inclined surface. The conical geometry provides curved surface contact that increases the area of interaction between tool carrier and holder, improving vibration resistance and positional stability while maintaining the ability to easily replace tools through the same interface.
2Device complexity
If a small inclined surface contact area is used, then the interface design is simple, but vibration resistance and tool life deteriorate
Solution Approach 1:
The conical contact surface extends the interface in the radial dimension, transforming a simple inclined plane into a three-dimensional conical geometry. This increases the contact area and improves vibration resistance without significantly complicating the overall interface design, as the conical shape integrates seamlessly with the existing tool carrier and holder structures.
Solution Approach 2:
The patent specifies a half-opening angle range (5° to 30°) for the conical contact surface, optimizing the balance between contact area (for vibration resistance) and interface simplicity. By adjusting this angular parameter, the design achieves improved reliability and vibration resistance while maintaining relatively simple interface construction and tool replacement procedures.
3Measurement precision
If the contact surface area is increased through conical geometry, then positional orientation precision improves, but the interface becomes more complex
Solution Approach 1:
The conical contact surface with a controlled half-opening angle provides curved surface contact that enhances positional orientation precision. The conical geometry naturally guides the tool carrier into correct alignment with the holder during insertion, improving positioning accuracy without requiring additional alignment features or complex adjustment mechanisms.
Solution Approach 2:
By specifying a half-opening angle range (5° to 30°), the patent optimizes the conical geometry to achieve precise positional orientation. The angular parameter controls the balance between contact area (for precision) and interface simplicity, ensuring that the geometric complexity remains manageable while delivering the desired positioning accuracy.
4Ease of manufacture
If a small contact surface is used at the shank part transition, then regrinding is easier, but the number of regrinding cycles is limited
Solution Approach 1:
The conical contact surface extends the usable material volume at the shank part transition by utilizing radial space. This increased material reservoir allows for multiple regrinding cycles while maintaining adequate contact surface area, thereby extending tool life without significantly increasing the difficulty of the regrinding process.
Solution Approach 2:
The half-opening angle parameter (5° to 30°) of the conical contact surface influences both the contact area and the material volume available for regrinding. By optimizing this angle, the design achieves a balance that provides sufficient material for multiple regrinding cycles while keeping the contact surface geometry manageable for standard regrinding operations.
