Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual transcription of navigational commands onto notepad is used, then the process is intuitive and simplistic, but it is cumbersome, time-consuming, and increases pilot workload

Engineering Contradiction:

Improveintuitive and simplistic processVSAvoidtime-consuming transcription process

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent uses optical character recognition (OCR) technology to capture handwritten notes from the notepad and automatically convert them into digital text format. This copying process eliminates the need for manual re-entry of navigational commands into the flight deck system, thereby reducing transcription time while maintaining the intuitive handwriting interface that pilots are already familiar with.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical process of manual typing and data entry with an automated optical recognition system. The handwriting recognition software substitutes for the manual mechanical action of keying in commands, converting the physical act of writing directly into digital data that can be processed by the flight management system.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If manual transcription of navigational commands is used, then the process is straightforward, but it introduces multiple opportunities for human error and confusion

Engineering Contradiction:

Improvestraightforward transcription processVSAvoidaccuracy of command entry

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the handwritten note is captured and converted to text, then displayed back to the pilot for verification before being submitted to the flight deck system. This allows the pilot to review and confirm the accuracy of the transcribed command, providing a check against errors while maintaining the simplicity of the handwriting interface.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

By creating an accurate digital copy of the handwritten command through OCR recognition, the system preserves the original pilot intent while eliminating transcription errors. The digital copy can be reviewed and verified before execution, providing a reliable record that reduces the risk of human error.

Inventive Principle:

Principle #26Copying

3Productivity

If handwritten data is captured and converted to alphanumeric format, then data entry is streamlined and pilot heads-down time is minimized, but additional processing and validation steps are required

Engineering Contradiction:

Improvedata entry efficiencyVSAvoidprocessing and validation system

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent implements automated validation rules that check the captured handwritten data for proper format, required fields, and logical consistency. The system performs self-validation on the entered commands, automatically identifying and flagging potential errors without requiring additional manual review steps, thereby maintaining high productivity while ensuring data quality.

Inventive Principle:

Principle #25Self-service

4Device complexity

If conventional notepad-based transcription is used, then no additional equipment is needed, but pilot workload is significantly increased by requiring additional tasks to resolve questionable commands

Engineering Contradiction:

Improveminimal equipment requirementsVSAvoidpilot workload

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The system provides immediate feedback to the pilot when questionable or unrecognized handwritten input is detected. The flight management system can query the captured data, request clarification, or highlight ambiguities, allowing the pilot to resolve issues quickly without having to manually re-enter entire commands or perform extensive verification procedures.

Inventive Principle:

Principle #23Feedback

AI summary

Embodiments of a touchscreen-enabled electronic device (referred to as a “digital pilot notepad”), methods, and program products facilitating the entry of handwritten pilot data into one or more flight deck systems are disclosed. In one embodiment, the digital pilot notepad includes an avionics interface over which alphanumeric input data is transmitted to a flight deck system, a touchscreen device, and a controller operably coupled to the avionics interface and to the touchscreen device. The controller is configured to digitally capture a handwritten pilot note written on the touchscreen device by a pilot, convert the handwritten pilot note to alphanumeric input data in a format compatible with the flight deck system, and subsequently submit the alphanumeric input data to the flight deck system over the avionics interface.
