Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If 3D rangefinder technology is used to capture physical scene data, then range measurement capability is improved, but the ability to display and integrate calculated geometric entities deteriorates
Solution Approach 1:
The patent combines calculated geometric entities (vectors, surfaces, volumes) with physical 3D range data sets into a unified display system. The software module merges these different types of data representations, allowing simultaneous visualization of both measured physical scenes and calculated geometric constructs within the same 3D spatial context, thereby resolving the contradiction between measurement capability and display versatility.
Solution Approach 2:
The patent creates a universal display system that can handle multiple types of data representations (physical range data points, vectors, surfaces, and volumes) through a single integrated software module. This multi-functional approach allows the system to adapt to various analysis needs including crime scene reconstruction, accident analysis, and terrorism scene investigation, transforming a specialized measurement tool into a versatile analytical platform.
2Measurement precision
If only physical scene data is displayed, then data accuracy is improved, but scene reconstruction and analysis capability deteriorates
Solution Approach 1:
The patent performs preliminary calculations to generate geometric entities (vectors representing trajectories, surfaces representing boundaries, volumes representing spaces) before final scene reconstruction. By pre-calculating these geometric representations from the raw range data, the system prepares analytical tools in advance that simplify subsequent scene reconstruction and analysis operations, making complex investigations more manageable without compromising the accuracy of the underlying physical measurements.

Implementation Method 1
A typical apparatus may in some manner measure the round trip time-of-flight of the beam from the apparatus's emitter to the target, or the reflector, and back to the apparatus's receiver
Implementation Method 2
Laser rangefinders use a variety of techniques to measure the range from the apparatus to a surface from which the laser beam is reflected
