Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If acceleration data is collected and compared to sample drivers to determine driving style rating, then drivers can receive feedback on their driving style for improved fuel efficiency, but additional hardware sensors would be required

Engineering Contradiction:

Improvedriving style feedbackVSAvoidhardware sensors

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The system makes existing vehicle sensors (accelerometer, speedometer) perform the additional function of driving style analysis. These sensors originally serve other purposes but are repurposed to collect acceleration data for comparing against sample drivers and generating driving style ratings, eliminating the need for dedicated additional hardware.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The vehicle's existing sensor system serves itself by providing data not only for its original functions but also for driving style feedback. The accelerometer and speedometer data, already being collected for vehicle operation, are simultaneously used to determine driving style ratings without requiring separate dedicated sensing hardware.

Inventive Principle:

Principle #25Self-service

2Device complexity

If existing vehicle sensors are used to collect acceleration data, then hardware complexity is reduced, but the ability to provide accurate driving style feedback is limited

Engineering Contradiction:

Improvehardware sensorsVSAvoidacceleration data accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The system processes acceleration data from existing sensors through comparison with sample drivers to generate driving style ratings that are fed back to drivers. This feedback loop enables continuous improvement of driving habits while utilizing the measurement capabilities of existing sensors effectively.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system transforms raw acceleration data parameters into meaningful driving style ratings by comparing against reference samples. The acceleration measurements are processed through statistical comparison and normalization to produce interpretable feedback about driving behavior relative to fuel efficiency standards.
