Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional adhesion testing methods are used, then testing can be performed, but the results are unreliable and the process is inefficient
Solution Approach 1:
The patent applies parameter changes by systematically varying multiple test parameters including polymer composition, surface treatment conditions, curing parameters, and environmental conditions to establish their effects on adhesion strength. This structured parameter exploration transforms unreliable conventional testing into a systematic methodology that delivers consistent, reliable results while improving efficiency through identified optimal parameter ranges.
2Manufacturing precision
If multiple variables are tested to find optimal polymer properties, then desired adhesive properties can be achieved, but the process becomes time-consuming
Solution Approach 1:
The patent employs preliminary action by pre-establishing the relationships between multiple variables (polymer composition, surface treatment, curing conditions) and adhesion outcomes through systematic testing. This creates a knowledge base of optimal parameter combinations that can be applied to future material selections, reducing the time required for polymer selection while maintaining precise control over adhesion properties.
Solution Approach 2:
By systematically exploring and documenting the effects of various parameters on adhesion strength, the patent creates a framework that allows rapid identification of suitable polymer combinations for specific applications, reducing material selection time while achieving desired manufacturing precision.
3Adaptability or versatility
If a flexible testing system is designed to test various variables, then it can accommodate different applications like dialyzers and hemofilters, but the system complexity increases
Solution Approach 1:
The patent applies universality by designing a testing system and methodology that can evaluate multiple variables (polymer properties, surface treatments, curing conditions, environmental factors) across different applications including dialyzers, hemofilters, and other medical devices. This multi-functional approach achieves versatility without proportionally increasing complexity, as the same systematic framework applies across different device types.
