Solution Overview
Problem
Current methods for measuring and recording evidence in industries like law enforcement and insurance are often inaccurate and inefficient, relying on visual approximations and traditional tools, leading to potential errors in classification and reporting, especially when direct measurement is not possible.
Innovation Solution
A portable measuring device with graduated indicia corresponding to common objects, allowing for direct and accurate measurement of areas or objects of interest, including features for recording size, shape, and angle, facilitating evidence classification and recording.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual assessment methods are used for measuring evidence, then the measurement process is simple and quick, but the measurement precision and accuracy are poor
Solution Approach 1:
The patent uses photographic copies and visual records of the evidence area, incorporating scale bars and reference objects into the images. This allows the evidence to be measured and analyzed later in the laboratory setting, combining the simplicity of visual documentation with the precision of controlled measurement environments.
Solution Approach 2:
The patent introduces scale bars, reference objects, and grid patterns as intermediary elements between the measurement tool and the evidence. These intermediaries provide known reference dimensions that enable accurate measurement calculations from photographs and visual assessments, bridging the gap between simple visual inspection and precise measurement.
2Adaptability or versatility
If traditional measuring tools are used, then the device complexity is low, but the adaptability to different evidence types and field conditions is limited
Solution Approach 1:
The patent employs universal measuring approaches that work across multiple evidence types including liquid spills, powder deposits, bullet impacts, and hail damage. The system uses standardized reference objects, grid patterns, and scale bars that can be applied to any evidence type, making the measurement system highly adaptable without requiring specialized tools for each evidence category.
Solution Approach 2:
The patent changes measurement parameters by using different reference objects and scale bars appropriate to the specific evidence type and size. For example, different sized reference coins or objects are selected based on the evidence dimensions, and measurement scales are adjusted accordingly. This allows the same basic measurement system to adapt to various evidence sizes and types through parameter modification rather than requiring different physical tools.
3Reliability
If direct measurement is attempted in field conditions, then the measurement can be obtained immediately, but the reliability and accuracy are compromised due to environmental factors
Solution Approach 1:
The patent performs preliminary documentation by taking photographs of the evidence in situ with embedded scale bars and reference objects immediately at the crime scene. This preliminary action captures the evidence state before environmental factors can alter it, and the measurements are then performed later in controlled laboratory conditions, ensuring both timely documentation and high measurement reliability.
Solution Approach 2:
The patent creates accurate photographic copies of the evidence with embedded measurement references. These copies preserve the evidence dimensions and characteristics for later analysis in controlled environments, eliminating the need to physically handle or relocate the actual evidence while maintaining measurement accuracy through the copied visual record with scale references.
4Measurement precision
If detailed measurements are recorded for later verification, then the measurement precision is improved, but the ease of operation and speed of documentation decreases
Solution Approach 1:
The patent uses self-service measurement documentation where the scale bar and reference objects are automatically included in the photographs themselves. The measurement information is embedded directly in the visual record, eliminating the need for separate manual measurement and documentation steps. The system serves itself by capturing both the evidence and its measurement references in a single photographic action.
Solution Approach 2:
The patent merges the documentation function and measurement function into a single photographic process. The scale bar, reference objects, and evidence are all captured in the same image, combining what would traditionally be separate steps (photographing the evidence, then separately measuring and recording dimensions) into one integrated action that produces both visual documentation and measurement data simultaneously.

AI summary
The invention is a method and measuring device configured for measurement by comparing the an area of interest or object with an object of comparable size and/or shape. This invention may be most useful when recording and classifying evidence. The measuring device should be portable and comprised of a flat, straight elongated member with measuring indicia along one or both the measuring edges, wherein the measuring indicia corresponds with values with labels of the standard sizes of comparable objects. The measuring indicia extends along the length of the measuring edge and the labels indicate the closest sized object. Other measuring indicia along the length of the measuring edge may also correspond to standard measurement units. The method should directly correlate a measurement with a comparable object for the purpose of recording evidence.
