Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for visualizing space debris lack effective methods to represent positional probabilities and collision risks in a clear, intuitive manner, often providing false impressions due to discrete particle representations and complex data processing requirements.
Innovation Solution
The development of systems and methods that utilize 3D representations to portray the positional probability of space debris, incorporating coloration, shading, and transparency to indicate density and collision risk, based on initial conditions and projected positions, with the aid of Poincare sections and connectivity matrices to create complex, time-evolving models.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If discrete particle representations are used to visualize space debris, then individual debris objects can be tracked, but false impressions of particle size and location are created
Solution Approach 1:
The patent uses graphical representations that copy the statistical distribution data rather than displaying actual debris particles. The visualization creates a simplified model that preserves the essential spatial probability information without misleading about actual particle sizes and locations.
Solution Approach 2:
The patent transforms the representation from discrete particle coordinates to continuous probability density fields. By changing the parameter representation from individual positions to spatial distribution functions, the system maintains measurement precision while eliminating misrepresentation of debris characteristics.
2Measurement precision
If complex data processing is used to model space debris distribution, then accurate positional probabilities can be calculated, but the visualization becomes difficult to interpret
Solution Approach 1:
The patent adds a visual dimension to probability data by rendering three-dimensional surfaces where height and color represent probability density. This dimensional transformation allows complex statistical data to be interpreted intuitively through visual cues while preserving computational accuracy.
Solution Approach 2:
The patent uses color gradients to encode probability density information, allowing operators to quickly assess high-risk regions. The color mapping transforms complex numerical data into an easily interpretable visual format while maintaining the underlying positional probability accuracy.
3Loss of information
If detailed risk assessments are provided in tabular form, then comprehensive collision risk data is available, but the information is not intuitively presented
Solution Approach 1:
The patent converts tabular risk assessment data into three-dimensional visual representations where spatial position, probability density, and temporal evolution are simultaneously displayed. This dimensional transformation preserves complete risk information while making it intuitively accessible through visual patterns.
Solution Approach 2:
The patent segments the risk assessment data into spatial zones with different probability densities, allowing operators to focus on high-risk regions. The segmentation organizes comprehensive data into manageable visual regions while maintaining complete information availability.
