Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in recreating repeatable and quantifiable flaring effects in the rear-of-lens environment, limiting the ability to control flaring for creative or exposure purposes.
Innovation Solution
A system comprising a lens mount with a collar and light emitting diodes (LEDs) that can be rotated to align with or out of perforations, allowing for tunable flaring effects by controlling the emission of light between the rear surface of the lens and the image plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If rear-of-lens modifiers are used to control flaring, then flaring effects can be suppressed or controlled, but the structural design of the lens and flange depth limit the effectiveness and versatility of these modifiers
Solution Approach 1:
The patent introduces a rotational dimension to the collar assembly, allowing it to rotate between multiple positions (0°, 45°, 90°, 135°, etc.). This rotational degree of freedom enables the same physical structure to achieve multiple flaring control functions by orienting the light-blocking surfaces at different angles, effectively adding a dimensional aspect to a previously static component.
Solution Approach 2:
The collar assembly is designed to perform multiple functions: it can block light rays at various angles, create different flaring patterns, and adapt to different lens types. By incorporating multiple light-blocking surfaces at different orientations within a single rotatable structure, the device achieves multi-functionality without requiring separate components for each flaring control scenario.
2Reliability
If traditional flaring suppression tools are used, then some control over flaring is achieved, but repeatable and quantifiable flaring effects are difficult to recreate
Solution Approach 1:
The patent replaces manual positioning and trial-and-error adjustment with a motorized rotational system controlled by a controller. The controller can automatically rotate the collar to precise angular positions, ensuring that the same flaring effect can be repeatedly achieved by returning to the same rotational position, thereby substituting mechanical precision with automated control.
Solution Approach 2:
The system incorporates a controller that can monitor and adjust the collar's rotational position to achieve desired flaring effects. This feedback mechanism allows the system to learn from previous successful flaring configurations and automatically reproduce them, ensuring consistency and repeatability across different shooting sessions.
3Adaptability or versatility
If light-blocking structures are added to control flaring, then flaring control is improved, but the device complexity and number of components increase
Solution Approach 1:
The patent merges multiple light-blocking surfaces and functional elements into a single integrally formed collar assembly. Instead of using separate baffles, shields, and light-blocking components that would each require individual mounting and adjustment, the invention combines all these functions into one rotatable structure that attaches to the lens mount, significantly reducing the number of separate components while maintaining comprehensive flaring control.
