Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual calculations are performed to estimate equipment count and size, then the electrical installation model can be built, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces manual mechanical calculations with an automated computer-based system that uses algorithms to calculate equipment counts, sizes, and specifications. The system automatically processes load requirements and generates conduit estimates without manual intervention, dramatically improving productivity while reducing time loss.
Solution Approach 2:
The system enables self-service by automatically generating electrical installation models, equipment schedules, and bills of materials without requiring manual calculation by contractors. The automated system serves itself by taking load inputs and producing complete installation plans with proper conduit sizing and equipment specifications.
2Ease of operation
If manual preparation of bill of material is performed for each equipment, then equipment suppliers can be contacted, but the process becomes time-consuming
Solution Approach 1:
The patent merges the preparation of bills of material and equipment schedules into a single automated process. Instead of manually preparing separate documents for each equipment type, the system generates consolidated schedules for conduits, cables, and all electrical equipment in one operation, making the process easier and faster.
Solution Approach 2:
The system replaces manual document preparation with automated computer-generated bills of material and equipment schedules. The computer system automatically compiles all equipment requirements into formatted schedules that can be directly used for vendor requests, eliminating time-consuming manual typing and formatting.
3Productivity
If conduit segment houses multiple cables with shared start and end points, then cable capacity is optimized, but estimating exact conduit count becomes challenging
Solution Approach 1:
The patent replaces manual conduit estimation with an automated calculation system that processes cable routing data and determines optimal conduit allocation. The computer system automatically handles the complexity of determining which cables share conduits based on start and end points, calculating exact conduit counts and sizes without manual intervention.
Solution Approach 2:
The system introduces an automated calculation algorithm as an intermediary between cable requirements and conduit specifications. This intermediary process automatically determines conduit sharing relationships, calculates required conduit counts, and ensures proper sizing based on the number and type of cables, simplifying the complex estimation process.
4Reliability
If safety standards like NEC are strictly followed, then installation safety is ensured, but calculation complexity increases
Solution Approach 1:
The patent replaces manual application of complex safety codes with an automated system that has NEC requirements built into its calculation algorithms. The computer system automatically applies National Electrical Code rules for conduit fill ratios, cable bundling, and sizing, ensuring safety compliance without requiring the contractor to manually interpret complex code provisions.
Solution Approach 2:
The system performs preliminary action by pre-programming all NEC safety requirements and calculation rules into the software before use. The automated system has safety standards already integrated, so it automatically ensures compliance during the calculation process without adding complexity to the user's workflow.
