Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple synchronized stationary image capture devices are used to obtain accurate three-dimensional projectile trajectory information, then measurement precision is improved, but device complexity and computing power requirements increase significantly

Engineering Contradiction:

Improvetrajectory reconstruction accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the trajectory reconstruction process into two parts: (1) multiple image capture devices independently capture two-dimensional trajectory data, and (2) a central processing system aggregates data from all devices and performs three-dimensional reconstruction. This segmentation allows each device to remain simple while the system achieves high precision through data fusion.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a central processing system as an intermediary that receives two-dimensional trajectory data from multiple image capture devices, sorts the data into groups, and performs three-dimensional reconstruction. This intermediary handles the complex computing tasks, allowing the image capture devices themselves to remain simple without requiring significant local computing power.

Inventive Principle:

Principle #24Intermediary (Mediator)
