Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for determining surface properties, such as those of motor vehicles, are costly due to the need for multiple filters and suffer from reduced precision due to variations in filter optical properties, even when filters are specified for the same wavelengths.
Innovation Solution
A device that uses a single set of filters shared across multiple optical paths between a radiation source and detector elements, allowing for efficient use of filter means and improved precision by enabling the use of filters with different optical properties in each path, and allowing spatially resolved detection of radiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple filters are installed in individual optical paths between radiation means and various radiation detectors, then spectral components can be measured at different angles, but the costs increase and precision decreases due to filter variations
Solution Approach 1:
The patent merges the filter resources by implementing a shared filter means that can be positioned in multiple optical paths. Instead of having separate filters for each detector, a single filter means is shared across all optical paths, eliminating filter variations while maintaining the ability to measure different spectral components at different angles.
Solution Approach 2:
The filter means is designed to be universal and multi-functional, capable of serving multiple optical paths and detectors simultaneously. This single filter means can be positioned in different locations to filter radiation for various detectors, providing spectral filtering capability across the entire measurement system without requiring multiple identical filters.
2Adaptability or versatility
If multiple filters are installed in individual optical paths, then spectral components can be measured, but the overall costs increase due to large number of filters required
Solution Approach 1:
The patent combines multiple filter functions into a single shared filter means. Instead of installing separate filters in each optical path, the system uses one filter means that can be positioned to serve multiple detectors, significantly reducing the total number of filters required and simplifying the overall device structure.
Solution Approach 2:
The filter means is designed as a universal component that can perform spectral filtering for multiple detectors and optical paths. This multi-functional design eliminates the need for duplicate filters, reducing device complexity while maintaining full spectral measurement capability across all measurement angles.
