Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the valve head and armature are connected directly, then the structure is simpler, but the processing requirements for the armature shape increase, leading to higher manufacturing costs
Solution Approach 1:
The patent introduces a guide rod as an intermediary component between the valve head and armature. The guide rod connects to the valve head at one end and to the armature at the other end, mediating the force transmission and motion guidance. This allows the armature to have simpler geometry (primarily a magnetic component) while still achieving reliable valve head actuation through the guide rod mechanism.
2Ease of manufacture
If the valve head and armature are connected directly, then the number of components is reduced, but the armature requires complex shaping and processing features
Solution Approach 1:
The patent segments the valve core into distinct functional components: the armature (magnetic component), the guide rod (mechanical connector), and the valve head (flow control component). This segmentation allows each component to be optimized for its specific function - the armature for magnetic actuation, the guide rod for mechanical connection and guidance, and the valve head for flow control - thereby reducing the processing complexity of the armature while maintaining overall functionality.
3Ease of manufacture
If a guide rod is used to connect the valve head and armature, then the armature processing costs are reduced, but the device structure becomes more complex
Solution Approach 1:
The guide rod serves multiple functions simultaneously: it acts as a mechanical connector between the armature and valve head, provides guidance for the valve head motion, transmits the electromagnetic force from the armature to the valve head, and serves as a structural support element. By consolidating these multiple functions into a single component, the overall structural complexity is minimized while achieving the goal of reduced armature processing requirements.
