Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual connection and verification through fire control panel is used, then system reliability is ensured, but operating efficiency is low
Solution Approach 1:
The input/output module performs self-testing through integrated test signal generation and indicator lights, eliminating the need for external fire control panel verification. The module tests its own ports and displays results independently, achieving self-service functionality that improves operating efficiency while maintaining reliability through automated verification
Solution Approach 2:
The system incorporates feedback mechanisms through indicator lights that display test results and port states. The module receives test signals, processes them through ports, and provides visual feedback via indicator lights, creating a closed-loop verification system that ensures reliability while enabling quick self-testing
2Productivity
If self-test mode with multiple ports and indicator lights is added, then detection efficiency is improved, but device complexity increases
Solution Approach 1:
The testing functionality is segmented into distinct components: test signal generation unit, port switching unit, indicator light units for each port, and mode activation. This segmentation allows each component to perform a specific function independently, improving detection efficiency through systematic port-by-port testing while managing complexity through modular design
Solution Approach 2:
The indicator lights serve multiple functions: displaying normal operation states, indicating test modes, showing test results, and revealing fault conditions. This multi-functionality reduces the need for separate display components for each function, improving detection efficiency without proportionally increasing device complexity
