Solution Overview

Problem

The configuration of Vehicle-Corner-Module (VCM)-based vehicles is error-prone due to unknown or overlooked VCM-specific limiting factors, leading to the creation of mechanically and electrically unsound or unsafe vehicles, especially when designed by unskilled personnel.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manually configure VCM-based vehicles without constraint computation, then ease of operation is improved, but reliability deteriorates due to unknown VCM-specific limiting factors

Engineering Contradiction:
Improveease of vehicle configurationVSAvoidmechanical and electrical compliance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary computation of mechanical and electrical constraints before presenting configuration options to the user. By pre-calculating compatible VCM characteristics and constraints based on selected vehicle characteristics, the system ensures that only compliant configurations are presented, thereby maintaining reliability while preserving ease of operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The server acts as an intermediary between the user's configuration choices and the VCM components. It computes constraints and determines compatibility, mediating the configuration process to ensure mechanical and electrical compliance without requiring the user to have specialized knowledge of VCM limiting factors.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If the system computes all VCM constraints and compatible characteristics, then manufacturing precision is improved, but device complexity increases

Engineering Contradiction:
Improvecompliance specification accuracyVSAvoidsystem computational complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The constraint computation process is segmented into distinct stages: first computing mechanical constraints, then electrical constraints, and finally determining compatible VCM characteristics. This segmentation allows the complex computation to be broken down into manageable parts, improving precision while controlling system complexity through structured processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically changes computational parameters based on user selections. When vehicle characteristics are selected, the system computes only the relevant constraints and compatible VCM characteristics specific to those selections, rather than pre-computing all possible constraints. This parameter-based approach improves manufacturing precision for the specific configuration while reducing overall device complexity.

Inventive Principle:
Principle #35Parameter changes

AI summary

Methods, systems, and networks for controlling design and manufacture of mechanically and electrically compliant VCM-based vehicles, in which a user manually and explicitly defines at least one vehicle characteristic and at least one VCM characteristic. User selection of one or more vehicle characteristics ensures that the selection of VCM characteristics will be that of VCM characteristics compatible with the selected vehicle characteristics. Similarly, user selection of one or more VCMs or VCM characteristics ensures that the selection of vehicle characteristics will be that of vehicle characteristics compatible with the selected VCM or VCM characteristics.
