Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If building management systems provide comprehensive control of entire facilities with multiple independent HVAC requirements, then system functionality and control capability are improved, but device complexity and difficulty of operation increase
Solution Approach 1:
The patent segments the complex BMS into multiple independent control zones or buildings, each with its own control strategy. This allows comprehensive facility control to be divided into manageable units, reducing the operational complexity while maintaining overall system functionality. Each segment can be independently assessed and optimized.
Solution Approach 2:
The performance assessment device serves multiple functions: it evaluates system performance, compares changes over time, identifies optimization opportunities, and provides recommendations across different BMS configurations. This universal tool addresses various complexity challenges through a single multi-functional platform.
2Adaptability or versatility
If building management systems are modified with new features and devices over time, then system capability and functionality are improved, but difficulty in monitoring changes and determining performance impact increase
Solution Approach 1:
The system establishes a baseline performance assessment before modifications are made. This preliminary measurement allows for straightforward comparison with post-modification performance, making it easy to detect and measure the impact of changes without complex tracking mechanisms.
Solution Approach 2:
The performance assessment device provides continuous feedback by comparing current system performance against historical baselines. This feedback mechanism automatically detects changes and quantifies their impact, eliminating the need for manual change tracking and performance analysis.
3Measurement precision
If comprehensive performance verification and assessment of large BMS systems is performed, then system performance understanding is improved, but time and resources required increase
Solution Approach 1:
The patent implements performance assessment at multiple levels: individual building level, zone level, and overall facility level. This partial assessment approach allows users to obtain comprehensive performance understanding by aggregating results from targeted, smaller-scale assessments rather than attempting to assess the entire large system simultaneously.
