Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional piping systems with multiple connections are used, then the system can be assembled with standard components, but the risk of leakage increases due to numerous joints and connectors
Solution Approach 1:
The patent integrates multiple piping components (pipes, valves, connectors) into a single monoblock structure manufactured by additive manufacturing. This merging eliminates numerous separate joints and connections that traditionally existed between components, thereby reducing leakage risk while maintaining ease of manufacture through standardized additive manufacturing processes
2Ease of operation
If threaded connections are used to join pipe components, then assembly is simplified, but leakage risk increases at connection points
Solution Approach 1:
The monoblock design integrates threaded connection features directly into the additive manufacturing process rather than assembling separate threaded components. This eliminates the interface between mating threaded parts where leakage occurs, while maintaining ease of operation by providing standardized connection interfaces on the external surfaces of the monoblock
3Ease of manufacture
If modular block systems are used for chemical dosing, then system assembly is facilitated, but the number of connections between blocks increases leakage risk
Solution Approach 1:
The patent combines multiple modular functional elements (pump, valves, flow meters, storage tanks) into a single integrated monoblock structure. This eliminates the inter-block connections that would otherwise exist in modular systems, removing leakage risk at connection interfaces while preserving modular functionality within the unified structure
4Productivity
If continuous vibration from dosing pumps is present, then chemical delivery function is maintained, but mechanical fatigue leads to leakage and failure
Solution Approach 1:
The monoblock construction integrates the pump and all piping components as a single rigid structure, eliminating relative movement and connection points between components. This reduces mechanical fatigue from continuous vibration by preventing stress concentration at joints, while maintaining chemical delivery function through the integrated pump system
Solution Approach 2:
The additive manufacturing process creates a composite structure with optimized material distribution and internal reinforcement features that enhance fatigue resistance. The monoblock design allows for strategic placement of material to withstand vibrational stresses while maintaining functional requirements for chemical dosing
