Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard copy fault manuals are used, then operators can refer to fault alarms and checklists, but the manuals are limited, prone to being misplaced or outdated, and lack detailed troubleshooting steps
Solution Approach 1:
The patent replaces the physical hard copy fault manual with a digital electronic fault manual stored in memory. This electronic copy can be accessed through the controller's display interface, eliminating the risks of misplaced or damaged physical manuals while providing comprehensive fault information and detailed troubleshooting checklists.
Solution Approach 2:
The patent substitutes the mechanical physical manual system with an electronic digital system. The controller retrieves fault information and displays it on a screen, replacing the need for operators to physically locate and read manual documents. This substitution provides real-time access to updated fault procedures without the constraints of physical media.
2Quantity of substance
If hard copy manuals are used, then fault information can be stored, but the information becomes outdated and cannot be updated in real-time
Solution Approach 1:
The patent implements a dynamic fault manual system where the controller can retrieve and display updated fault information from memory. The system adapts to changing engine control requirements by allowing real-time updates to fault procedures and checklists through the electronic storage medium, eliminating the static nature of physical manuals.
Solution Approach 2:
The controller system incorporates feedback mechanisms to retrieve current fault information from memory and display it to operators. This feedback loop ensures that the fault manual information is always current and reflects the latest engine control requirements, allowing for real-time adaptation to system changes.
3Ease of repair
If detailed troubleshooting steps are provided, then operators can effectively diagnose and correct malfunctions, but the manual becomes complex and difficult to navigate
Solution Approach 1:
The patent segments the fault manual into organized categories and subcategories, with each fault condition having its own dedicated section. The controller displays fault information in a structured format with clear headings, bullet points, and numbered procedures, making the comprehensive troubleshooting steps easy to navigate and understand despite the detailed content.
