Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermal resistors are used to heat the bushing for forming a joint, then the joint can be formed between the sleeve part and pipe parts, but the complexity of the device increases due to the need for electrical current conduction and resistor installation
Solution Approach 1:
The patent introduces a bushing as an intermediary component that contains the thermal resistors and facilitates the joining process. The bushing acts as a mediator between the electrical heating system and the pipe parts, allowing the thermal resistors to heat the bushing material which then forms the joint with the pipe parts. This intermediary approach simplifies the overall system by consolidating the heating mechanism within a single replaceable component.
2Ease of manufacture
If a bushing is used to join pipe parts with thermal resistors, then a joint can be formed, but the manufacturing process becomes more complex due to resistor installation and electrical connection requirements
Solution Approach 1:
The patent divides the joining system into distinct segments: the bushing component (which may be pre-manufactured with thermal resistors), the pipe parts to be joined, and the electrical connection system. This segmentation allows the bushing to be manufactured and tested separately, then installed as a complete unit, simplifying the overall manufacturing process by enabling modular production and assembly.
3Reliability
If electric current is conducted to thermal resistors to heat them for joint formation, then the joint can be formed, but the energy consumption increases
Solution Approach 1:
The patent utilizes the phase transition of the bushing material from solid to molten state through resistive heating. The thermal resistors heat the bushing material to its melting point, causing it to transition to a molten state that can then flow and form bonds with the pipe parts. As the material cools, it solidifies to create a strong joint. This phase transition approach allows for efficient energy utilization, as the heating is concentrated precisely where needed and the phase change itself facilitates the joining process.
