Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If periodic chemical-physical checks are carried out by external laboratories, then fluid analysis can be performed with specialized equipment, but immediate and continuous monitoring cannot be achieved
Solution Approach 1:
The device is divided into multiple independent analysis modules (first analysis module, second analysis module, etc.), each capable of performing specific fluid analyses. This segmentation allows the system to maintain laboratory-grade precision while enabling continuous monitoring through parallel operation of multiple modules.
Solution Approach 2:
The system enables self-monitoring of fluid characteristics directly at the industrial machine location, eliminating the need for external laboratories. The integrated sensor units and analysis modules perform measurements autonomously, providing immediate results without sample transport or external intervention.
2Productivity
If multiple analysis modules are integrated into a single device, then real-time multi-parameter analysis is enabled, but device complexity increases
Solution Approach 1:
Multiple analysis modules are merged into a single integrated device with shared components such as the housing, fluid supply system, and control unit. This merging approach enables multi-parameter analysis while managing complexity through common infrastructure rather than completely separate systems.
Solution Approach 2:
The device is designed with universal components that serve multiple functions. For example, the fluid supply system serves all analysis modules, and the housing provides both structural support and fluid distribution pathways. This multi-functionality reduces overall system complexity while maintaining high productivity.
3Area of stationary object
If the device is designed for small space installation, then it can be deployed at industrial machine locations, but manufacturing and assembly become more challenging
Solution Approach 1:
The analysis modules are arranged in a nested or stacked configuration within a compact housing, with each module occupying a specific zone. The first analysis module is positioned in a first zone and the second analysis module in a second zone, allowing efficient space utilization while maintaining manufacturing feasibility through modular assembly.
Solution Approach 2:
The device transitions from a horizontal spread-out layout to a vertical stacked arrangement, utilizing the third dimension (height) to reduce the footprint. Multiple analysis modules are stacked vertically within the housing, enabling small space installation while simplifying manufacturing through standardized vertical module assembly.
