Engineering Contradiction Analysis
1Reliability
If extensive virtual testing is performed using computer numerical simulation, then passenger safety certification is improved, but data processing costs and time increase
Solution Approach 1:
The patent divides a complete impact simulation into multiple sequential partial simulations. Each partial simulation models a specific time interval of the impact event separately. By segmenting the simulation, the computational workload is distributed across multiple smaller, manageable simulations that can be processed more efficiently than a single comprehensive simulation.
Solution Approach 2:
The patent performs preliminary partial simulations to generate simulation data for specific time intervals before the complete analysis is needed. These preliminary simulations prepare intermediate results that can be reused and combined later, avoiding the need to reprocess entire impact scenarios when analyzing different aspects or variations.
2Reliability
If extensive virtual testing is performed using computer numerical simulation, then passenger safety certification is improved, but processing costs increase
Solution Approach 1:
The patent segments the simulation into partial simulations that can be executed independently and combined. This segmentation allows computational resources to be used more efficiently by processing smaller time intervals separately, reducing the overall computational burden and associated costs while maintaining the rigor needed for safety certification.
Solution Approach 2:
The patent discards the need to reprocess entire impact simulations when analyzing different scenarios. Instead, it recovers and reuses simulation data from partial simulations that have already been computed, significantly reducing redundant computational work and associated processing costs.
3Measurement precision
If full-scale simulations are run from initial conditions to impact, then complete impact analysis is achieved, but computational requirements and time consumption increase
Solution Approach 1:
The patent segments the impact analysis into multiple partial simulations covering different time intervals. Each partial simulation maintains measurement precision for its specific interval while avoiding the computational overhead of running complete full-scale simulations for every analysis need. The segmented approach preserves impact analysis completeness through proper combination of partial results.
Solution Approach 2:
The patent applies partial action by performing simulations only for the specific time intervals and conditions needed rather than running complete simulations from initial conditions to final impact for all possible scenarios. This partial simulation approach maintains necessary measurement precision while significantly improving simulation efficiency.

AI summary
Computational numerical analysis for passenger seating assemblies can be performed by generating a combined computer numerical simulation based on two or more partial numerical simulations of different assemblies and/or virtual passengers or anthropomorphic test dummies (ATDs). The partial numerical simulations may be run for a common, nonzero period of time, after which first simulation data from the first numerical simulation and second simulation data from the second numerical simulation can be captured and used for generating the combined numerical simulation. The combined numerical simulation can simulate a collision between the different assemblies and/or virtual ATDs by assembling the first and second partial simulation data such that the modeled assemblies collide in the combined computer numerical simulation. Any suitable number of combined numerical simulations in a variety of specific variations may be regenerated using the first and second partial simulation data.
