Vehicle Entry Path Optimizer for Musculoskeletal Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle design does not adequately consider the musculoskeletal abilities of users when optimizing entry and exit paths, leading to potential discomfort and difficulty for various user segments.
Innovation Solution
A method and system that analyze vehicle user data and vehicle dimensions to determine a three-dimensional path for entry and exit, calculate a user satisfaction score, and virtually update vehicle dimensions to improve user satisfaction by optimizing the musculoskeletal compatibility of the entry and exit paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vehicle dimensions are optimized for general use, then productivity is improved, but ease of operation deteriorates for users with limited musculoskeletal ability
Solution Approach 1:
The system changes vehicle dimension parameters (rocker height, door opening width, stepover height, roof height) based on user musculoskeletal characteristics. By dynamically adjusting these parameters according to user segment (able, elderly, corpulent, disabled), the system optimizes both entry/exit efficiency and comfort for diverse user groups.
Solution Approach 2:
The system segments users into different categories (able user, elderly user, corpulent user, disabled user) based on musculoskeletal ability. Each segment receives customized vehicle dimension recommendations, allowing the system to address the specific needs of different user groups rather than applying a one-size-fits-all approach.
2Ease of operation
If vehicle dimensions are customized for specific user segments, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The system manages complexity by systematically varying four key vehicle dimension parameters (rocker height, door opening width, stepover height, roof height) based on user segment. This structured parameter change approach allows customization without creating unmanageable system complexity.
Solution Approach 2:
The system performs preliminary analysis of user musculoskeletal characteristics and pre-determines optimal vehicle dimensions before the user actually enters or exits the vehicle. This advance preparation reduces the complexity of real-time adjustments and improves user experience.
3Adaptability or versatility
If traditional vehicle design methods are used, then manufacturing precision is maintained, but adaptability to different user needs deteriorates
Solution Approach 1:
The system maintains manufacturing precision by providing specific, quantified dimension recommendations (rocker height, door opening width, stepover height, roof height) for different user segments. These are not vague guidelines but precise parameter specifications that can be directly applied in vehicle design and manufacturing.
Solution Approach 2:
The system enhances adaptability by segmenting the user population into distinct groups (able, elderly, corpulent, disabled) and providing tailored dimension specifications for each segment. This allows manufacturers to produce vehicles optimized for specific user groups while maintaining precise dimensional control.
Data Source
AI summary
A method for analyzing a vehicle user entry and egress into a vehicle includes receiving vehicle user data and receiving vehicle data. The vehicle data includes vehicle dimensions. The method further includes determining a three-dimensional path to enter and egress the vehicle using the vehicle user data and the vehicle data, determining a user satisfaction score of the three-dimensional path to enter and egress the vehicle, comparing the user satisfaction score with a predetermined score threshold to determine whether the user satisfaction score is greater than the predetermined score threshold; and virtually updating the vehicle dimensions until the user satisfaction score is greater than the predetermined score threshold in response to determining that the user satisfaction score is not greater than the predetermined score threshold.
