Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional electrically conductive multilayer materials are used for leak detection, then leak detection functionality is provided, but installation complexity increases and measurement accuracy decreases due to delamination
Solution Approach 1:
The patent combines the glass fibre reinforcement, binding agent, fire retardant compound, and electrically conductive carbon particles into a single integrated multi-layer material. This merging eliminates the need for separate installation of multiple components, reducing installation complexity while maintaining measurement accuracy through the integrated structure that prevents delamination between layers.
Solution Approach 2:
The patent creates a composite material consisting of glass fibres woven into a web structure, impregnated with binding agent, fire retardant compound, and electrically conductive carbon particles. This composite structure provides mechanical strength, fire resistance, and electrical conductivity simultaneously, eliminating the need for separate functional layers and their associated installation complexities.
2Reliability
If conventional conductive layers are used, then basic conductivity is provided, but conductivity properties are insufficient for effective leak detection across the sealed structure
Solution Approach 1:
The patent distributes electrically conductive carbon particles locally throughout the glass fibre web structure, ensuring conductivity is present at every point where leak detection is needed. This local distribution of conductive properties throughout the entire sealed structure enables effective detection of leaks at any location without requiring complex external conductive networks.
3Ease of operation
If multiple separate layers are used to provide conductivity and protection, then functional requirements are met, but installation becomes more complicated and costly
Solution Approach 1:
The patent merges reinforcement fibres, binding agents, fire protection compounds, and electrically conductive particles into a single multi-layer material that can be installed as one unit. This consolidation reduces the number of separate components from multiple distinct layers to a single integrated material, significantly easing installation while maintaining all required functions.
Solution Approach 2:
The patent creates a universal material that simultaneously provides mechanical reinforcement, fire protection, electrical conductivity, and leak detection functionality. This multi-functional material eliminates the need for separate components for each function, reducing both the quantity of substances needed and the complexity of installation procedures.
