Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the vehicle system uses standard range estimation methods, then the estimation is simple and quick, but the accuracy deteriorates when additional items or passengers are added to the vehicle

Engineering Contradiction:
Improverange estimation accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary detection of planned configuration changes (trailers, cargo, passengers) before the vehicle journey begins. The detection module identifies intended additions to the vehicle configuration at the starting location or stopover locations, allowing the range estimation to be proactively adjusted before the actual weight is added, thus maintaining accuracy without requiring real-time monitoring during travel

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The range estimation system transitions from a static calculation method to a dynamic adaptive method. The estimation module continuously updates the range prediction based on detected configuration changes, making the system flexible and responsive to varying vehicle loads while maintaining computational efficiency through incremental adjustments rather than complete recalculations

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If the system detects and estimates range based on planned configuration changes, then the range estimation accuracy improves, but the complexity of detecting and measuring increases

Engineering Contradiction:
Improverange estimation accuracyVSAvoidconfiguration change detection difficulty
Core Design Contradiction:
Measurement precisionVSDifficulty of detecting and measuring

Solution Approach 1:

The detection module is designed with multi-functionality to handle various types of configuration changes through a unified detection framework. It can identify different kinds of additions (trailers, cargo, passengers) using the same basic detection mechanisms, reducing the overall complexity by avoiding the need for separate specialized detection systems for each type of configuration change

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system introduces an intermediary detection module that acts as a bridge between the user's planned configuration changes and the range estimation algorithm. This intermediary layer translates diverse configuration changes into standardized parameters that the estimation module can process, simplifying the detection and measurement process while maintaining accuracy

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the system provides accurate range estimation with configuration changes, then driver confidence and reliability improve, but the computational energy consumption increases

Engineering Contradiction:
Improverange estimation reliabilityVSAvoidcomputational energy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system applies partial action by focusing computational resources only on the specific aspects of range estimation that are affected by configuration changes. Rather than performing complete range recalculations from scratch, the estimation module adjusts only the relevant portions of the estimation based on detected changes, reducing overall computational energy consumption while maintaining reliability

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system implements a feedback mechanism where the detection module's findings are fed back to the estimation module, which then adjusts the range prediction accordingly. This feedback loop enables the system to maintain high reliability through continuous adaptation while minimizing energy consumption by only processing necessary updates rather than performing exhaustive recalculations

Inventive Principle:
Principle #23Feedback
