Vibrating Lens Beam Deflection for High Resolution Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection apparatuses face challenges in achieving high resolution images when the resolution of the image to be projected exceeds the resolution of the projection apparatus, as they must remove pixels to match the lower resolution.
Innovation Solution
A vibrating lens system is introduced, comprising a control assembly and a light-transmissive assembly. The control assembly, with a substrate and a control coil, interacts with a magnetic assembly in the light-transmissive assembly to deflect projection beams, allowing for the adjustment of beam positions to achieve higher effective resolutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the projection apparatus uses a fixed lens to project images, then the structure is simple and easy to manufacture, but the resolution is limited by the projection apparatus resolution and cannot achieve high resolution when projecting high resolution images
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed lens into a vibrating lens that can dynamically adjust its position. The lens is driven to vibrate at specific frequencies and amplitudes, enabling it to deflect projection beams and achieve higher effective resolution by projecting multiple sub-images that combine to form a high resolution image, thus resolving the contradiction between manufacturing simplicity and projection resolution.
Solution Approach 2:
The patent directly applies mechanical vibration by causing the lens to vibrate through electromagnetic driving forces. The vibrating lens modulates the projection beams by deflecting them during vibration, which enables the system to achieve higher resolution than the static projection apparatus resolution would allow, while maintaining a relatively simple overall structure without requiring complex mechanical moving parts.
2Loss of information
If the projection apparatus removes pixels to match its lower resolution, then the device complexity remains low, but the loss of information occurs as high resolution image details are discarded
Solution Approach 1:
The patent applies periodic action by using the rhythmic vibration of the lens to periodically deflect projection beams and create multiple sub-images. This periodic modulation allows the system to utilize all pixels from the high resolution image without removal, as the vibrating lens directs different pixel information to different positions during each vibration cycle, thereby preserving image detail information while maintaining efficient processing through the regular vibrational pattern.
3Manufacturing precision
If a vibrating lens system is introduced to achieve higher resolution, then the projection resolution is improved, but the device complexity increases due to additional control assemblies and magnetic components
Solution Approach 1:
The patent applies universality by designing the vibrating lens assembly where the lens serves multiple functions: it acts as both the optical element for image projection and the moving element for beam deflection. The magnetic assembly and control coil work together as an integrated electromagnetic actuator that provides both the driving force and the control mechanism, reducing the need for separate complex mechanical drive systems and thereby limiting the increase in device complexity.

AI summary
A vibrating lens comprises a control assembly configured to control a light-transmissive assembly to deflect and the light-transmissive assembly located at a side of the control assembly. The control assembly includes a substrate having a first opening and a first edge region surrounding the first opening and a control coil printed on the first edge region. The light-transmissive assembly includes a bearing plate having a second opening and a second edge region surrounding the second opening, a lens covering the second opening and a magnetic assembly located on the second edge region. The lens and the magnetic assembly are disposed at a side of the bearing plate proximate to the control assembly. Orthogonal projection of the first opening on a plane parallel to a surface of the substrate away from the lens coincides with orthogonal projections of the lens on the plane and the second opening on the plane.
