Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a guide component is used to prevent the tapping screw from becoming slanted, then the fastening precision is improved, but the alignment between the guide component and the pilot hole becomes difficult, increasing the operation complexity
Solution Approach 1:
The patent introduces a positioning component as an intermediary tool between the guide component and the workpiece. This positioning component includes positioning pins that temporarily align the guide component with the pilot holes, making the alignment process easier without compromising the precision provided by the guide component during fastening
Solution Approach 2:
The positioning component performs preliminary alignment action before the actual fastening operation. By pre-aligning the guide component with the pilot holes using positioning pins, the system eliminates the alignment difficulty during the main fastening process, allowing the guide component to focus solely on maintaining fastening precision
2Manufacturing precision
If a guide component is used to prevent oblique fastening, then the fastening quality is improved, but the work time increases due to repeated alignment for multiple pilot holes
Solution Approach 1:
The positioning component is designed to be universal and can be used for aligning the guide component with multiple different pilot holes. The positioning pins can engage with various hole positions, allowing the same positioning component to serve multiple alignment functions across different fastening locations, thereby reducing the need for multiple specialized tools and decreasing total work time
Solution Approach 2:
By performing preliminary alignment with the positioning component before each fastening operation, the system ensures that the guide component is quickly and accurately positioned without requiring time-consuming manual alignment adjustments, thus maintaining high fastening quality while reducing overall work time

AI summary
A tapping screw fastening jig includes a guide component and a positioning component. The guide component includes a first base member provided with a guide hole portion through which a tapping screw is insertable at a position corresponding to each of pilot holes in a use state of the tapping screw fastening jig. The positioning component includes a second base member, and at least two positioning pins provided on the second base member, where the at least two positioning pins are provided at positions corresponding to at least two of the pilot holes. Each of the at least two positioning pins includes a first outer diameter portion that is insertable into the pilot hole, and a second outer diameter portion that is connected to the first outer diameter portion on a base end side of the first outer diameter portion and is insertable through the guide hole portion.
