Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for guiding airplanes to dock with passenger bridges often rely on incorrect or outdated data about airplane type and version, leading to potential accidents due to misalignment of wings or doors, as the data in central computer systems is not always accurate.
Innovation Solution
A method that uses an antenna to receive information from airplanes, extracts the identification number and coordinates, and retrieves the correct airplane type and version from a database to accurately display this information to the pilot, ensuring correct alignment and safe docking by controlling the display and distance measuring devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If distance measuring lasers and displays are used to guide airplane docking, then the positioning accuracy is improved, but the reliability deteriorates due to incorrect airplane type data in central computer systems
Solution Approach 1:
The patent implements feedback by having the display show the actual airplane type and version detected from transmitted information, allowing verification against the expected type. This feedback loop enables the system to identify and correct data errors, ensuring the docking process uses accurate airplane type information rather than relying solely on potentially incorrect central computer system data.
Solution Approach 2:
The system performs self-verification by automatically receiving and processing transmitted information containing airplane identification data. The local system independently verifies the airplane type against the database and displays it for confirmation, eliminating reliance on external manual input or potentially erroneous central system data, thus improving both reliability and measurement precision.
2Ease of operation
If the display shows expected airplane type from central computer system, then the docking process is simplified, but the accuracy of airplane type identification deteriorates due to data errors
Solution Approach 1:
The system performs preliminary verification by receiving and displaying the actual airplane type information before the docking process begins. This allows operators to verify the correct airplane type is identified and take corrective action if discrepancies are found, ensuring accurate identification while maintaining operational simplicity through automated preprocessing and display of verified data.
Solution Approach 2:
By displaying the actually detected airplane type and version from transmitted information rather than only expected types, the system provides feedback that enables verification of data accuracy. This feedback mechanism maintains operational simplicity while dramatically improving identification accuracy by allowing real-time verification against actual airplane characteristics.
3Adaptability or versatility
If manual input of airplane data is allowed, then the system is more flexible, but the reliability deteriorates due to risk of incorrect data input
Solution Approach 1:
The system automatically receives and processes airplane identification data through transmitted information containing identification numbers and coordinates, eliminating the need for manual data input. This self-service approach maintains system flexibility by automatically adapting to different airplanes while dramatically improving reliability by removing human error from the data entry process.
Solution Approach 2:
The patent replaces manual mechanical data input with automated electronic reception of transmitted information. The antenna receives signals containing airplane identification data, which is then automatically processed and displayed. This substitution eliminates manual input errors while maintaining system adaptability through automated data extraction and verification processes.
