Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional tooth tapping machine and tooth turning machine are used without positioning, then the manufacturing process is simple, but the position alignment between through hole and assembling portion becomes random
Solution Approach 1:
The patent introduces a positioning device as an intermediary component that mediates between the tooth tapping machine and tooth turning machine. This positioning device includes a positioning plate with positioning holes and positioning protrusions that ensure accurate relative positioning between the through hole and assembling portion during the manufacturing process, thereby resolving the position alignment accuracy issue without significantly complicating the overall manufacturing process.
Solution Approach 2:
The patent applies preliminary action by pre-positioning the workpiece on the positioning plate before machining operations. The positioning holes and positioning protrusions are designed in advance to establish the correct relative positions of the through hole and assembling portion before the actual cutting operations begin, ensuring accurate position alignment from the start of the manufacturing process.
2Productivity
If conventional manufacturing method is used, then the device structure is simple, but the yield rate is affected due to random position alignment
Solution Approach 1:
The positioning device serves as a mediator that guarantees consistent position alignment across all manufactured parts. By using the positioning plate with standardized positioning holes and protrusions, the system ensures that every through hole and assembling portion is accurately aligned, thereby improving the yield rate by reducing defects caused by misalignment while maintaining a relatively simple device structure.
Solution Approach 2:
The positioning plate creates a reusable template or copy of the correct position relationship between the through hole and assembling portion. This standardized positioning pattern can be repeatedly used across multiple manufacturing cycles, ensuring consistent high-quality output and improving yield rate through reliable position alignment.
3Manufacturing precision
If positioning device is introduced, then position alignment accuracy is improved, but the device complexity increases
Solution Approach 1:
The positioning device is designed with pre-configured positioning holes and positioning protrusions that establish the correct geometry before manufacturing begins. This preliminary setup ensures accurate position alignment without requiring complex real-time adjustments or sophisticated control systems during the manufacturing process, thereby limiting the increase in device complexity.
Solution Approach 2:
The positioning plate appears to be a relatively simple, possibly disposable or easily replaceable component that provides precise positioning without requiring high-cost, complex machinery. This approach achieves improved position alignment accuracy using a cost-effective, simple positioning device rather than investing in expensive complex manufacturing equipment.

AI summary
A precise manufacturing method for manufacturing a liquid container is described hereinafter. Assemble a first jig element with a second jig element. Make a first datum plane at the first jig element, and make a second datum plane at the second jig element, next, unlock the first jig element and the second jig element. Assemble a base with the first jig element, assemble a cup-shaped element with the second jig element. Make a through hole at the cup-shaped element, and the through hole is corresponding to the second datum plane, make an assembling portion at the base, and the assembling portion together with a perforation is corresponding to the first datum plane. Detach the second jig element, detach the first jig element, and then the cup-shaped element is assembled with the base, so the perforation and the through hole are located at the same direction.
