Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional methods are used to process ingots and metal steel pieces, then metal solid parts can be produced, but the processes become complicated and expensive with multiple steps and logistical transport
Solution Approach 1:
The patent replaces conventional mechanical processing methods (ingot processing, steel piece processing) with microwave irradiation technology. The microwave heating system directly heats metal powder within a high-melting-point material matrix, eliminating the need for complex mechanical processing steps,物流运输, and multiple manufacturing stages while achieving the same production goal of creating metal solid parts
Solution Approach 2:
The invention changes the fundamental processing parameters by using microwave radiation (electromagnetic energy) instead of conventional thermal or mechanical processing. By controlling microwave irradiation parameters (power, time, frequency) and material composition ratios, the process achieves simplified production with direct transformation of metal powder to metal solid, bypassing traditional multi-step processing
2Ease of manufacture
If conventional processing methods are used, then metal solid parts can be produced, but costs increase due to multiple processing companies and logistical transport
Solution Approach 1:
The patent merges multiple separate processing operations into a single integrated microwave processing step. The metal powder, high-melting-point material, and binding agent are combined into a unified composite material that is processed in one batch, eliminating the need for sequential processing by multiple companies and reducing logistical transport requirements
Solution Approach 2:
The microwave processing system enables self-contained production where all necessary transformations (heating, bonding, solidification) occur within a single processing cycle without requiring external transport or intermediate handling steps, thereby reducing both time and cost losses associated with logistics
3Reliability
If conventional processing methods are used, then metal solid parts can be produced, but reliability decreases as one disrupted step can affect all downstream steps
Solution Approach 1:
The patent segments the production process into independent, parallelizable units by using metal powder as the starting material that can be processed individually. Each batch of metal powder can be processed independently through microwave irradiation, so that disruptions in one batch do not affect other batches or downstream steps, thereby improving overall process reliability
Solution Approach 2:
The invention performs preliminary mixing of metal powder with high-melting-point material and binding agent to create a pre-formed composite material. This preliminary preparation ensures that all necessary components are in place before processing, reducing the risk of disruptions during the actual production step and improving process reliability
4Temperature
If metal powder is directly heated with microwaves, then heating can occur, but the high-melting-point material is needed to prevent melting of the metal powder
Solution Approach 1:
The high-melting-point material serves as an intermediary medium that enables controlled heating of the metal powder. It has higher microwave absorption characteristics than the metal powder, allowing it to heat up first and then transfer heat to the metal powder, while its high melting point prevents direct melting of the metal powder during the heating process
