Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If complex energy management algorithms are implemented to provide comprehensive output data, then the information completeness is improved, but the ease of interpretation deteriorates
Solution Approach 1:
The patent segments complex energy management information into distinct visual elements including a flight path vector (FPV) showing desired trajectory, energy cones indicating speed/altitude ranges for stabilization, and symbolic representations of configuration changes. This segmentation transforms comprehensive but complex algorithmic output into discrete, easily interpretable visual components that pilots can quickly understand and act upon.
2Measurement precision
If detailed energy management data is displayed to ensure complete information, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent projects energy management information from abstract algorithmic space into a three-dimensional graphical representation on the display. The FPV extends in spatial dimension to show trajectory, while energy cones add volumetric dimension to represent speed and altitude ranges. This dimensional transformation maintains precise energy assessment capabilities while presenting information in an intuitively understandable visual format rather than complex tabular or numerical displays.
3Reliability
If comprehensive energy management output is provided to ensure safety, then the reliability is improved, but the ease of operation deteriorates due to information overload
Solution Approach 1:
The patent employs color-coded symbolic representations to convey energy management status and required actions. Different colors indicate various flight phases, energy states, and configuration requirements. This color-coding system allows pilots to quickly assess the current situation and required actions without processing complex numerical data, maintaining high reliability through comprehensive information while significantly reducing pilot workload through intuitive visual cues.

AI summary
A computer-implemented flight display system including a computer processor that is capable of determining a current energy situation of an aircraft, an electronic display device, and a graphical user interface (GUI) provided on the electronic display device. The GUI includes a current aircraft position symbol, an optimal aircraft position symbol, and at least one symbol indicating a position for changing aircraft configuration. Relative positioning on the GUI of the optimal aircraft position system and the at least one symbol indicating a position for changing aircraft configuration is based at least in part on the determined current energy situation of the aircraft.
