Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual operator intervention is used for camera calibration, then the operator can perform the calibration function, but the throughput is limited and consistency is poor

Engineering Contradiction:

Improvecalibration throughputVSAvoidcalibration consistency

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system enables self-service calibration by having the mobile device automatically perform calibration movements under software control. The device moves itself through predefined trajectories without requiring manual operator intervention, allowing simultaneous calibration of multiple devices and eliminating variability introduced by human operators.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the manual mechanical operation of moving devices with an automated software-controlled mechanical system. The calibration software orchestrates precise, repeatable movements of multiple devices simultaneously, substituting human physical manipulation with programmable automated control to achieve consistent results across all devices.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If a single operator calibrates one device at a time, then the calibration process is simple, but the efficiency and speed are low

Engineering Contradiction:

Improvecalibration speedVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges multiple calibration operations into a single unified process. Multiple mobile devices are calibrated simultaneously within one system framework, combining what would traditionally require multiple sequential operations into a parallelized workflow that increases throughput while managing complexity through integration.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The calibration software is designed as a universal system that can handle multiple devices of potentially different types simultaneously. The same software platform and fixture system accommodate various devices, providing multi-functional capability that increases productivity without proportionally increasing system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
