Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The loading of passenger airplanes is often time-consuming and complicated by the diverse types of bags brought onboard, leading to delays and inefficiencies in the loading process.
Innovation Solution
A computing device application simulates the loading of an airframe by receiving airframe, passenger, and bag profile files, allowing for the simulation of bag placement into bins based on dimensions and location, and calculating boarding times, with options for different orientations and bin spaces, including convex and non-convex hulls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual baggage loading is performed, then flexibility in handling diverse bag types is maintained, but loading time increases and productivity decreases
Solution Approach 1:
The system performs preliminary simulation of baggage loading before actual loading occurs. The simulation module pre-calculates optimal placement positions for various bag types based on bin dimensions and bag profiles, creating a loading plan that guides the actual loading process. This preliminary action resolves the contradiction by preparing adaptive placement strategies in advance, enabling fast execution during actual loading.
Solution Approach 2:
The system creates digital copies (profiles) of physical bags and bins to simulate the loading process. Bag profiles capture dimensions and characteristics of diverse bag types, while bin profiles represent storage spaces. The simulation operates on these copies to determine optimal placement, allowing the system to handle bag diversity virtually before physical loading, thus maintaining adaptability while improving productivity.
2Manufacturing precision
If simulation complexity is increased to handle diverse bag orientations and bin configurations, then placement accuracy improves, but device complexity increases
Solution Approach 1:
The simulation system segments the loading problem into distinct components: bag profiles (dimensions, characteristics), bin profiles (dimensions, configurations), and placement algorithms. Each component is handled separately with dedicated data structures and processing logic. This segmentation allows the system to manage complexity while maintaining high placement accuracy through specialized handling of each element type.
Solution Approach 2:
The system uses parameter-based profiles to represent bags and bins, where key dimensions and characteristics are stored as adjustable parameters. The simulation varies parameters such as bag orientation angles and placement positions to find optimal configurations. This parameter-driven approach enables accurate modeling of complex scenarios without requiring complex hard-coded logic for each situation.
3Volume of stationary object
If multiple bag orientations are simulated to find optimal placement, then space utilization improves, but calculation time increases
Solution Approach 1:
The simulation evaluates multiple bag orientations (excessive action) to ensure optimal space utilization, but applies pruning logic to stop evaluating orientations once a satisfactory placement is found. The system doesn't exhaustively check every possible orientation combination but rather samples sufficient orientations to achieve near-optimal packing. This partial/excessive approach balances thoroughness with computational efficiency.
Solution Approach 2:
The system pre-calculates feasible orientation ranges and valid placement zones before attempting actual bag placement. By establishing preliminary constraints on which orientations are even worth considering, the system reduces the search space significantly. This preliminary filtering action enables the simulation to evaluate multiple orientations without excessive calculation time.
