Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple cameras and sensors are integrated into head-mounted and torso-mounted devices to provide 360° monitoring and ocular movement tracking, then measurement precision and reliability of remote testing are improved, but device complexity increases

Engineering Contradiction:

Improveocular movement tracking precisionVSAvoiddevice complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The monitoring system is divided into separate functional modules: head-mounted image capture devices with multiple cameras for field of view monitoring, separate ocular movement tracking sensors, and torso-mounted devices for additional monitoring angles. Each module performs a specific function, allowing for optimized design of individual components while maintaining overall system precision.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The head-mounted device integrates multiple functions into a single wearable unit: it combines forward-facing cameras for field of view capture, rearward-facing cameras for monitoring candidate behavior, ocular movement tracking sensors, and audio recording capabilities. This multi-functional integration improves measurement precision while managing device complexity through unified design.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If continuous real-time video and data streaming is implemented from remote test terminals to central servers, then reliability and security of remote testing are improved, but loss of energy and data transmission requirements increase

Engineering Contradiction:

Improvesecurity of remote testingVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The system implements continuous real-time streaming of video and data from multiple cameras and sensors to the central server throughout the entire examination duration. This continuous action ensures complete monitoring coverage and maintains security reliability, with the understanding that the energy cost is necessary for the duration of the test.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The system creates digital copies of the test environment through video and data streaming, transmitting these copies to the central server for monitoring and analysis. This allows remote verification of test conditions without requiring physical presence, maintaining security while enabling energy-efficient digital monitoring compared to in-person proctoring.

Inventive Principle:

Principle #26Copying

3Ease of operation

If head-mounted devices with multiple cameras are used to monitor test candidates, then ease of operation for remote monitoring is improved, but weight of the moving object increases

Engineering Contradiction:

Improveease of remote monitoringVSAvoidweight of head-mounted device

Core Design Contradiction:

Ease of operationVSWeight of moving object

Solution Approach 1:

Multiple camera systems are merged into a single head-mounted device: forward-facing cameras, rearward-facing cameras, and ocular movement tracking sensors are integrated into one wearable unit. This consolidation improves ease of operation by providing comprehensive monitoring coverage from a single device position, while the combined design optimizes weight distribution on the head.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The monitoring system transitions from two-dimensional flat monitoring to three-dimensional omnidirectional monitoring by adding rearward-facing cameras and depth-sensing capabilities. This dimensional expansion provides comprehensive spatial coverage of the test environment and candidate behavior, improving remote monitoring effectiveness while distributing weight across multiple sensor types.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

Secure monitoring of the field of view of remotely located operators comprises capturing video and data signals representing a series of images including the forward field of view of the operator and the operator's ocular movement and may also include rearward and other operator fields of view. The images are transmitted to an operator microprocessor which, in turn, transmits the signals to a centrally located server where the signals are processed and the resulting information saved in files dedicated to respective operators.
