Adjustable Third Optical Body for Projector Light Beam Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior art projectors of light beams have limitations in modifying optical effects, as the fixed position and distance of the prismatic lens restrict the variability of the outlet angle and optical effects, limiting the projector's operational capabilities.
Innovation Solution
The projector features a third optical body with independent adjustment movements, allowing it to be positioned between the first and second optical bodies or between the second optical body and the outlet lens, enabling a wider range of optical effects without increasing the projector's dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the third optical body is fixed to the frame or articulated to the first/second optical body in prior art solutions, then the projector structure is stable, but the optical effects variability is limited due to fixed position and distance
Solution Approach 1:
The third optical body is made dynamically adjustable through an independent movement mechanism that allows it to move along the longitudinal axis between different positions (first, second, and third positions). This dynamic positioning capability enables variation of optical effects by changing the relative distances between the third optical body and the first/second optical bodies, while the movement is constrained within a controlled range to maintain structural stability.
2Adaptability or versatility
If the third optical body is positioned interposed between the first and second optical body, then optical effects are enhanced, but the projector length increases
Solution Approach 1:
The third optical body is positioned and moved along the longitudinal axis of the projector, utilizing the existing dimensional space within the projector housing. By adjusting the position of the third optical body along this axis, the system achieves multiple optical configurations (interposed between first and second optical body, or between second optical body and outlet lens) without requiring additional lateral or vertical space that would increase the overall projector footprint.

Implementation Method 3
at least a third optical body defining, for example, but without limiting the scope of the invention, a prismatic lens generating an optical effect acting on the light beam (for example, splitting the light beam in several parts, or, depending on the position, variations of the outlet angle from the projector of luminous figures formed with the prismatic lens)
