Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drilling tools face challenges in achieving a secure connection between the basic body and the covering element, which affects the efficiency and reliability of the drilling process.
Innovation Solution
The proposed drilling tool design features a covering element with a gap that takes up an angle range between 30° and 270°, allowing for a secure assembly and connection between the basic body and the covering element, thereby enhancing the tool's structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the covering element is designed with a gap to enable assembly with the basic body, then the ease of manufacture is improved, but the structural integrity and reliability of the connection may deteriorate
Solution Approach 1:
The covering element is segmented by introducing a gap that divides it into two separate portions. This segmentation allows the covering element to be assembled onto the basic body in a straightforward manner, improving ease of manufacture while maintaining connection reliability through the specific angular dimension of the gap
Solution Approach 2:
The gap in the covering element is designed with a specific angular parameter (between 30° and 270°) that optimizes both assembly ease and connection reliability. By carefully controlling this geometric parameter, the design achieves a balance between manufacturability and structural integrity
2Ease of operation
If the gap angle is increased to facilitate assembly, then the ease of operation is improved, but the structural strength may deteriorate
Solution Approach 1:
The gap angle is optimized within a specific range (30° to 270°) to balance assembly ease and connection strength. This parameter optimization ensures that the covering element can be easily assembled while maintaining sufficient structural strength for reliable operation
3Device complexity
If the covering element is made entirely outside the basic body, then the device complexity is reduced, but the manufacturing precision requirements may increase
Solution Approach 1:
The covering element is segmented with a gap that allows it to be placed entirely outside the basic body during assembly. This segmentation reduces structural complexity while the specific angular dimension of the gap provides natural alignment features that minimize manufacturing precision requirements
