Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a power transmission mechanism with a clutch mechanism is used to transmit driving power to each rotary tool, then the rotary tools can be driven at predetermined rotation phases, but simultaneous engagement of engaging portions with engaged portions becomes difficult to achieve
Solution Approach 1:
The input portions are made adjustable relative to the tool-rotating drive shaft, allowing the phase of each engaging portion to be dynamically adjusted. This enables the operator to easily achieve simultaneous engagement of all engaging portions with their corresponding engaged portions, resolving the contradiction between precise rotation phase control and ease of engagement operation
Solution Approach 2:
The phase parameter of each engaging portion can be changed by adjusting the position of the input portion on the drive shaft. This parameter adjustment capability allows precise control of rotation phases while maintaining ease of operation, as the adjusting means provides a straightforward mechanism for achieving the desired phase alignment
2Adaptability or versatility
If multiple rotary tools are mounted on a tool rest with individual power transmission mechanisms, then each tool can be independently controlled, but the device complexity increases
Solution Approach 1:
Multiple input portions are fixed to the same tool-rotating drive shaft, merging the power transmission source for all rotary tools into a single drive shaft. This reduces device complexity by eliminating the need for separate drive shafts or complex individual power transmission paths, while still allowing independent phase adjustment of each tool through its respective input portion
Solution Approach 2:
The tool-rotating drive shaft serves as a universal power transmission element for all rotary tools simultaneously. Each input portion can be independently adjusted to provide the required phase control for different tools, making the single drive shaft multi-functional and reducing overall system complexity
