Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional mold device is used to manufacture tee type joint pipes, then the production process can be simplified, but the joint pipes are not molded as a single piece resulting in weak connection parts
Solution Approach 1:
The manufacturing process is segmented into distinct stages: preparing the straight pipe with molding hole, positioning the molding stone through the insertion hole, and executing the forming operation. This segmentation allows each component (straight pipe, molding stone, mold device) to be optimized independently while ensuring they work together to produce an integrated tee type pipe without weak connection parts
Solution Approach 2:
The molding stone acts as an intermediary tool that is inserted through the insertion hole into the molding hole. It serves as the mediating element that transfers the forming force from the press device to the metal plate, enabling the creation of the branch pipe portion while maintaining structural integrity throughout the entire pipe structure
2Adaptability or versatility
If traditional multi-piece assembly is used for tee type pipes, then manufacturing flexibility is maintained, but productivity is reduced due to assembly requirements
Solution Approach 1:
The invention merges the formation of the straight pipe and branch pipe into a single integrated molding operation. The molding stone, when pressed through the molding hole, simultaneously forms the branch pipe portion while the straight pipe portion is already in place, creating a seamless integrated structure that eliminates the need for separate assembly operations and improves productivity
3Reliability
If an oval-shaped molding hole is drilled in a metal plate before roll-forming, then an integrated tee type pipe can be formed, but the manufacturing process becomes more complex
Solution Approach 1:
The oval-shaped molding hole is drilled in the metal plate before the roll-forming process. This preliminary action ensures that the molding hole is properly positioned and shaped in the flat metal plate, which then transforms into the correct three-dimensional form during roll-forming. This preliminary preparation simplifies the overall process by eliminating the need for complex post-forming operations while ensuring structural integrity
