Solution Overview

Problem

Current methods for validating messages in connected vehicle networks, such as Flowchain, lack control over which wireless devices perform validation, leading to potential delays that can be fatal in high-speed scenarios due to random selection of devices with varying capabilities.

Innovation Solution

A method where wireless devices in a geographical area are assigned weightings based on their capabilities, allowing for the selection of the most capable devices to perform validation, ensuring messages are validated within a predetermined time frame.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If random selection of wireless devices is used for message validation, then any device can participate in validation, but validation time becomes unpredictable and may exceed fatal thresholds in high-speed scenarios

Engineering Contradiction:
Improveparticipation capabilityVSAvoidvalidation delay
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent changes the selection parameter from random to capability-based weighting. Each wireless device is assigned a weighting value representing its validation capability, and devices are selected based on these weightings rather than randomly. This ensures that devices with higher validation capabilities are more likely to be selected, reducing validation time while maintaining system adaptability.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements dynamic selection of validation devices based on real-time capability assessments. The weighting values can be updated to reflect current device states, allowing the system to adapt to changing conditions while consistently selecting the most capable devices for validation tasks.

Inventive Principle:
Principle #15Dynamics

2Productivity

If all wireless devices are equipped to perform validation, then validation capacity increases, but hardware resources are wasted on devices not selected for validation

Engineering Contradiction:
Improvevalidation capacityVSAvoidhardware utilization efficiency
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent applies partial action by selecting only a subset of wireless devices for validation tasks based on their capability weightings. Instead of requiring all devices to be fully equipped and active for validation, the system activates only the necessary number of devices with sufficient capability, optimizing resource utilization while maintaining adequate validation capacity.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system changes the operational state of wireless devices from all-potential to selected-active based on capability parameters. By using weighting values to determine which devices should perform validation, the system optimizes hardware utilization by keeping validation-capable devices in standby or active states only when needed, rather than continuously consuming resources.

Inventive Principle:
Principle #35Parameter changes

3Speed

If capability-based weighting is implemented for device selection, then validation speed improves, but system complexity increases due to weighting calculation and management

Engineering Contradiction:
Improvevalidation speedVSAvoidselection mechanism complexity
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-calculating and storing capability weighting values for each wireless device before validation tasks arise. These weightings are determined in advance based on device specifications and performance characteristics, so when validation is needed, the system can quickly select appropriate devices without performing complex real-time calculations, thus maintaining high validation speed while managing system complexity.

Inventive Principle:
Principle #10Preliminary action
