Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical imaging apparatuses face issues such as non-convergence of light, presence of mirror images, high production costs, and ghost images due to complex manufacturing processes, which hinder the formation of sharp real images.
Innovation Solution
An optical imaging apparatus with a flat plate-shaped light-controlling panel featuring numerous light-reflecting elements arranged in a crossed configuration, where the first and second reflective surfaces are parallel and bisecting angles coincide with centerlines, reducing the ratio of light passing through once and inhibiting mirror images, allowing for sharper real image formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If light is reflected once at reflection surfaces in existing optical imaging apparatuses, then light transmission is simplified, but light is not converged to one point and mirror images are formed
Solution Approach 1:
The patent divides the single reflection surface into two separate reflective surfaces (first and second reflective surfaces) positioned at different locations. This segmentation allows light to undergo two sequential reflections, each contributing to convergence at different stages, ultimately focusing light precisely at the image formation position while preventing mirror image formation.
Solution Approach 2:
The patent introduces a spatial dimension by positioning the first and second reflective surfaces at different locations along the optical path. This dimensional arrangement enables light to be converged through multi-stage reflection, achieving precise focal point convergence that prevents mirror image formation while maintaining optical path efficiency.
2Manufacturing precision
If multiple reflection surfaces are used to converge light, then image sharpness improves, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges the functions of multiple reflection surfaces into a coordinated system where the first and second reflective surfaces work together as an integrated optical element. This merging approach achieves complex light convergence functionality while maintaining a relatively simple overall device structure, avoiding the need for separate complex optical components.
Solution Approach 2:
The reflective surfaces in the patent serve multiple functions: they reflect light, converge light to specific positions, and prevent mirror image formation. This multi-functionality reduces the need for additional separate optical elements, thereby simplifying the overall device structure while achieving precise image sharpness.
3Manufacturing precision
If complex manufacturing processes are used to form precise optical elements, then image quality improves, but production costs increase
Solution Approach 1:
The patent uses molding techniques to replicate precise optical surfaces, creating multiple identical optical elements with consistent precision. This copying approach through molding enables high-volume production of precise optical elements at reduced costs compared to individual precision machining or fabrication of each element.
Solution Approach 2:
The patent optimizes geometric parameters of the reflective surfaces (such as angles and positions) to achieve precise light convergence while maintaining manufacturability. By carefully selecting and adjusting these parameters, the design achieves high image quality with manufacturing processes that are more cost-effective than alternative high-precision approaches.
