Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for shooting scattered blood marks at right angles are inconvenient and often result in errors during blood morphology analysis, as they require separate devices like tripods and can be difficult to use when marks are spread in various directions.
Innovation Solution
An apparatus comprising a first body with a lens coupling portion and a housing portion, and a second body with a surface contact portion and insertion portion, allowing for accurate shooting of scattered blood marks at right angles without a separate device, along with optional LED lighting and a transparent measurer for size measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If tripods or mini tripods are used to shoot scattered blood marks at right angles, then shooting accuracy is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines the camera mounting function and the right-angle positioning function into a single integrated device. The camera is directly mounted on the bloodstain pattern analysis device, eliminating the need for separate tripods. The device includes a camera mounting unit with a camera and a bloodstain pattern shooting unit that work together as one system, resolving the contradiction by merging multiple functions into a unified apparatus.
Solution Approach 2:
The bloodstain pattern analysis device is designed to serve multiple functions: it can analyze bloodstain patterns, mount a camera for documentation, and ensure right-angle shooting positioning. This multi-functional design eliminates the need for separate specialized equipment like tripods, improving ease of operation while maintaining shooting accuracy through the integrated right-angle positioning capability.
2Measurement precision
If tripods or mini tripods are used to shoot scattered blood marks at right angles, then shooting accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The camera mounting function and right-angle positioning function are merged into a single integrated device. The camera is directly mounted on the bloodstain pattern analysis device, which simplifies the operation by eliminating the need to set up and adjust separate tripods. The integrated design allows the operator to perform both analysis and documentation in one setup, improving ease of operation while maintaining accuracy.
Solution Approach 2:
The device includes self-aligning features such as the right-angle positioning mechanism that automatically ensures proper shooting angles without requiring manual adjustment by the operator. The camera mounting unit and bloodstain pattern shooting unit work together to self-correct positioning, reducing the skill level and effort required by the operator while maintaining high shooting accuracy.
3Ease of operation
If shooting is performed without using tripods or mini tripods, then ease of operation is improved, but shooting accuracy deteriorates
Solution Approach 1:
The bloodstain pattern analysis device is designed to perform multiple functions including pattern analysis and camera mounting for documentation. This multi-functional design allows the device to serve as both the analysis tool and the mounting platform, eliminating the need for separate tripods while maintaining shooting accuracy through its integrated right-angle positioning capability.
Solution Approach 2:
The device incorporates adjustable and adaptable components that can dynamically adjust to different bloodstain patterns and shooting requirements. The camera mounting unit can be positioned and adjusted to ensure the camera lens is perpendicular to the target surface, providing the flexibility needed to maintain accuracy across various scenarios without requiring rigid tripod structures.
4Measurement precision
If a separate device like a tripod is used, then shooting accuracy is improved, but device complexity increases
Solution Approach 1:
The patent merges the camera mounting function with the bloodstain pattern analysis device into a single integrated system. The camera is mounted directly on the analysis device, which includes built-in right-angle positioning capabilities. This eliminates the need for separate tripods and reduces the overall number of components, thereby reducing device complexity while maintaining shooting accuracy through the integrated positioning mechanism.
