Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If paper-based checklists are used, then pilots can access checklist information, but readability deteriorates in low-light conditions and during turbulence
Solution Approach 1:
The patent replaces the mechanical paper-based checklist system with an electronic display system that presents checklist items on a screen. This electronic presentation eliminates the physical handling and readability issues of paper checklists during turbulence and in various lighting conditions, as the display can be optimized for different environments.
Solution Approach 2:
The electronic display system allows for dynamic adjustment of display parameters such as brightness, contrast, and font size to optimize checklist visibility under different lighting conditions and flight phases. This parameter adaptability ensures reliable readability whether in bright daylight, dim cockpit lighting, or during turbulent conditions.
2Ease of operation
If paper checklists are physically handled, then pilots can reference them, but distractions increase and focus is compromised
Solution Approach 1:
The patent replaces the mechanical act of physically handling paper checklists with an electronic interface that can be accessed and manipulated through minimal physical interaction. The electronic system eliminates the need to shuffle, fold, or manually manage paper pages, thereby reducing physical distractions and maintaining pilot focus on flight tasks.
3Adaptability or versatility
If traditional digital checklist solutions are used, then pilots can access digital checklists, but adaptability to different aircraft types is limited
Solution Approach 1:
The patent implements a universal checklist system that can accommodate multiple aircraft types and configurations within a single device. The system stores and manages checklist data for different aircraft models, allowing pilots to select and access appropriate checklists based on the specific aircraft being operated. This multi-functionality eliminates the need for separate checklist devices for each aircraft type.
Solution Approach 2:
The checklist system dynamically adapts its content and presentation based on the selected aircraft type, flight phase, and specific operational context. The system can reconfigure checklist items, groupings, and display formats to match the requirements of different aircraft and operational scenarios, providing customized checklists without requiring complex manual configuration.
4Loss of information
If digital checklist systems are introduced, then pilots can access checklist information, but real-time interaction capabilities are minimal
Solution Approach 1:
The patent implements an interactive checklist system that provides immediate feedback to pilots as they complete checklist items. The system tracks completion status in real-time, updates the display to reflect current position, and can provide alerts or reminders for incomplete items. This feedback mechanism ensures that checklist information remains current and helps pilots maintain situational awareness without requiring constant manual verification.
