Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional tool positioning devices with channels are used, then cooling effect is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The tool positioning device is divided into multiple independent hollow cylindrical portions arranged in parallel, each capable of independent movement and cooling function. This segmentation allows the cooling function to be distributed across multiple simple components rather than requiring a single complex device with integrated channels.
Solution Approach 2:
The hollow cylindrical portions serve multiple functions: they provide structural support for positioning the tool, enable cooling through air flow through their hollow interiors, and facilitate easy assembly and disassembly. This multi-functionality eliminates the need for separate cooling channels while achieving both positioning and cooling objectives.
2Temperature
If conventional tool positioning devices with channels are used, then cooling effect is improved, but manufacturing cost increases
Solution Approach 1:
By dividing the cooling function into multiple independent hollow cylindrical portions, each component can be manufactured separately using simple processes without requiring complex internal channel machining. This segmentation significantly reduces manufacturing difficulty and cost while maintaining effective cooling.
Solution Approach 2:
The hollow cylindrical portions are designed as simple, inexpensive components that can be easily replaced if needed. Their simple structure allows for low-cost manufacturing, and their modular nature enables easy replacement without affecting other components, reducing overall manufacturing and maintenance costs.
3Manufacturing precision
If conventional tool positioning devices are used, then positioning function is provided, but tool life decreases due to heat
Solution Approach 1:
The positioning device uses multiple independent hollow cylindrical portions that can be individually adjusted to achieve precise positioning. The segmentation allows for fine-tuning of each portion's position while simultaneously providing cooling through air flow, thus maintaining positioning precision while extending tool life through effective heat dissipation.
Solution Approach 2:
Air flow through the hollow cylindrical portions acts as an intermediary cooling medium that removes heat from the tool without interfering with the positioning function. This intermediary cooling mechanism allows the positioning structure to remain simple while effectively managing tool temperature to extend tool life.

AI summary
A tool positioning device and a machining element have simple structures which can reduce running cost. In addition to a hole that engages with a shank of an end mill, a channel is provided so that it penetrates through the device such that one end thereof communicates with an upper face of the device and the other end communicates with a lower end of the device. In this case, it is more effective to provide a concave portion that is opened to the upper face and communicates with the hole. The same effect may be obtained by making a cylindrical hole, for example, instead of the channel.
