Turret Optical Element Assembly for Fast Multi-Filter Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing turret-type optical element devices require time-consuming and labor-intensive operations for replacing filters, lenses, or pinhole patterns, as each type needs to be attached individually to the turret.
Innovation Solution
A turret-type optical element device with an integrally formed optical element part having multiple optical characteristic regions, allowing easy replacement by rotating a turret that includes a turret body and an element pressing part, with recesses and openings for stable attachment, enabling multiple optical characteristics to be switched with a single operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple optical elements (filters, lenses, pinhole patterns) are prepared separately and attached individually to the turret, then each optical element can be selected and replaced, but the replacement operation becomes time-consuming and labor-intensive
Solution Approach 1:
The patent combines multiple separate optical elements (filters, lenses, pinhole patterns) into a single integrated optical element part that can be attached to the turret as one unit. This merging eliminates the need to attach each optical element separately, significantly reducing replacement time while maintaining the ability to select different optical characteristics by rotating the turret to different positions.
2Adaptability or versatility
If multiple separate optical elements are attached to the turret individually, then each type can be selected, but the attachment operation becomes complex and requires multiple steps
Solution Approach 1:
The patent integrates multiple optical elements into a single optical element part with a unified attachment structure. This single part includes multiple optical characteristic regions (different filters, lenses, or pinhole patterns) that can be attached to the turret in one operation, simplifying the attachment process while preserving optical characteristic variety through turret rotation.
Solution Approach 2:
The optical element part is designed as a universal component that can provide multiple optical functions (different filters, lenses, pinhole patterns) within a single structure. This multi-functional design allows the turret to select among various optical characteristics without requiring separate attachment mechanisms for each type of optical element.
3Manufacturing precision
If multiple optical elements are replaced one by one, then each replacement can be performed accurately, but the overall replacement process becomes inefficient
Solution Approach 1:
The patent combines multiple optical elements into a single optical element part that is attached to the turret as one unit. This approach maintains attachment accuracy through a unified attachment interface while dramatically improving replacement efficiency by eliminating the need for multiple separate attachment operations. The turret rotation mechanism ensures precise positioning of the selected optical characteristic region.

AI summary
A turret-type optical element device includes an attaching part attached to a lensless camera having no optical elements on an optical path, and a turret rotatably attached to a substrate having an optical path opening and including an optical element part having at least two optical characteristic regions in which characteristics in optical characteristics possessed by an optical element are different from each other. The turret is rotated such that each of the optical characteristic regions and the optical path opening are faced each other, the optical element part itself is an integrally formed product that is detachably attached to the turret, the turret-type optical element device is attached to the lensless camera through the attaching part, and constitutes an imaging system that includes no optical elements, other than the optical element part on the turret, on the optical path.
