Rotating Clear Prism Optical Viewing Device with Interchangeable Filters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical viewing devices require cumbersome mechanical arrangements and expensive colored prisms to observe electromagnetic radiations, which are cumbersome and costly to maintain, and do not efficiently accommodate variations in observers' eyes.
Innovation Solution
The use of a single clear prism mounted for rotational movement about an axis perpendicular to the observer's line of sight, combined with interchangeable optical filters for blue, red, and yellow wavelengths, and independently adjustable prisms for each eye to accommodate eye variations, allowing for simultaneous rotation and angular offset.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If colored prisms are used to observe electromagnetic radiations, then the observation of specific wavelength spectrums is enabled, but the device becomes expensive and mechanically complex
Solution Approach 1:
The patent separates the color filtering function from the prism function. Instead of using colored prisms that require complex mounting mechanisms, the invention uses separate interchangeable optical filters (blue, red, yellow, clear) that can be easily exchanged. This segmentation eliminates the need for complex mechanical arrangements while maintaining the ability to observe different wavelength spectrums.
Solution Approach 2:
The invention extracts the color filtering capability from the prism itself and places it in separate interchangeable filters. The prism becomes a simple clear optical element, while the color selection is handled by separate filter components that can be independently chosen and exchanged, simplifying the overall device mechanism.
2Adaptability or versatility
If multiple colored prisms are mounted for successive presentation, then different wavelength spectrums can be observed, but the device requires cumbersome mechanical arrangements
Solution Approach 1:
The invention introduces dynamic interchangeability of filters. Instead of a fixed mechanical arrangement of multiple prisms, the system allows the observer to dynamically exchange different optical filters (blue, red, yellow, clear) based on the observation requirements. This dynamic adaptation is achieved through simple filter exchange mechanisms rather than complex mechanical rotations or translations.
3Reliability
If colored prisms are used to sensitise the human brain to optical phenomena, then observation of electromagnetic radiations is enhanced, but the cost and complexity increase
Solution Approach 1:
The invention replaces expensive colored prisms with inexpensive interchangeable optical filters. These filters can be easily manufactured and exchanged, reducing the overall cost of the device while maintaining the ability to enhance observation of electromagnetic radiations through different wavelength spectrums.
4Device complexity
If a single clear prism is used for rotational movement, then the number of expensive prisms is reduced, but the focal length may vary
Solution Approach 1:
The invention addresses focal length variation by allowing rotational movement of the single clear prism while maintaining consistent optical performance. The rotation is controlled to preserve focal length consistency, and the interchangeable filter system provides additional control over optical parameters to ensure manufacturing precision and observation accuracy.

AI summary
An optical viewing device is constructed having a housing with a passage extending therethrough to permit an observer to view a subject through the passageway. A pair of optical prisms are mounted within the housing and passageway, each prism designated to accommodate one of the observer's eyes. The prisms are mounted for rotation upon an axis substantially perpendicular to the observer's line of sight through the passageway. Limited inter-prism rotation is permitted to accommodate variations in the observer's left and right eyes. A filter supporting means is provided to support selected colored optical filters to be placed adjacent the opening of the housing to permit the observer to view a subject through the passageway, prisms, and optical filters.
