Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing ignition interlock devices are inflexible and fail to adapt to current situations, leading to either undue burdensome testing or lax testing requirements, which limits their effectiveness in reducing driving under the influence.

Innovation Solution

A system with onboard and remote components that uses driver identification, adaptive testing rules, and predictive analysis to dynamically determine the necessity and type of intoxicating substance testing based on factors like time, location, and driving history, allowing for geo-fence definitions and communication with an operations center for centralized rule management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional ignition interlock devices require mandatory blood alcohol testing before vehicle startup, then drunk driving is reduced, but the device becomes unduly burdensome when the risk of drunk driving is low

Engineering Contradiction:

Improveeffectiveness in reducing drunk drivingVSAvoidburden of testing requirements

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically adjusts testing requirements based on real-time contextual factors including time of day, geographic location, driver identification, and historical data. Testing intensity varies from mandatory pre-startup breathalyzer tests to periodic rolling tests during driving, creating a flexible regime that adapts to changing risk profiles rather than applying static requirements

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes multiple parameters simultaneously including testing frequency, testing type (pre-startup vs. rolling tests), threshold levels, and geographic zones. These parameter adjustments are based on predictive analytics that evaluate driver behavior patterns, time-location contexts, and historical compliance data to optimize testing intensity

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If conventional ignition interlock devices use fixed testing requirements, then implementation is simple, but the device fails to adapt to current situations and contexts

Engineering Contradiction:

Improveability to adapt to current situationsVSAvoidcomplexity of adaptive testing system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A remote server acts as an intermediary between the vehicle's ignition interlock device and the operations center. The server receives contextual data from multiple sources including GPS location, time stamps, driver identification systems, and historical testing records, then processes this information through predictive analytics algorithms to generate dynamic testing rules that are transmitted back to the vehicle device

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements continuous feedback loops where testing results, location data, and driver behavior patterns are constantly monitored and fed back into the predictive analytics model. This feedback mechanism allows the system to learn from past behavior, adjust risk assessments, and modify future testing requirements in real-time based on actual performance data

Inventive Principle:

Principle #23Feedback

3Reliability

If blood alcohol testing is required at all times, then safety is maximized, but unnecessary testing increases burden and reduces compliance

Engineering Contradiction:

Improvesafety against drunk drivingVSAvoidtime spent on unnecessary testing

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system applies testing intensity proportional to assessed risk levels rather than uniform maximum testing. Low-risk situations (such as daytime driving in low-risk zones with clean historical records) trigger minimal or no pre-startup testing, while high-risk situations trigger enhanced testing protocols including multiple breathalyzer requirements and rolling tests during driving

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Rule-based intoxicating substance testing associated with vehicles. At least some of the various embodiments are methods including: receiving a signal that a prospective driver intends to drive a vehicle; retrieving at least one previously stored rule regarding intoxicating substance testing associated the vehicle; retrieving data relevant to the rule; determining whether intoxicating substance testing is indicated by the rule; enabling the vehicle responsive to an indication that intoxicating substance testing is not indicated; and administering an intoxicating substance test to the prospective driver responsive to an indication that an intoxicating substance test is indicated. And if the intoxicating substance test is administered: enabling the vehicle responsive to the prospective driver passing the intoxicating substance test, the enabling by the onboard device; and disabling the vehicle responsive to the prospective driver failing the intoxicating substance test, the disabling by the onboard device.
