Solution Overview

Problem

Existing projectors face challenges in achieving high-resolution imaging while maintaining a compact size, as most actuators are uniaxial or biaxial, limiting the ability to shift beams in multiple directions effectively.

Innovation Solution

A projection device with a first and second actuating module that moves optical elements in multiple directions, including perpendicular and angled shifts, allowing the image beam to be projected in various directions, thereby enhancing resolution without increasing device size or cost.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If uniaxial or biaxial actuators are used to shift the beam, then the device structure is simple, but the resolution is limited and cannot achieve high-resolution imaging

Engineering Contradiction:
Improveimaging resolutionVSAvoidactuator structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple actuating modules (first and second actuating modules) into a single integrated system that can shift the beam in multiple directions simultaneously. This merging approach achieves high-resolution imaging capabilities without requiring separate actuators for each direction, thus improving resolution while controlling overall device complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention transitions from uniaxial or biaxial actuation to multi-dimensional beam shifting by introducing actuating modules that can move the beam along multiple axes (first direction, second direction, and third direction). This dimensional expansion enables high-resolution imaging across the entire projection surface rather than being limited to single or dual directions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Manufacturing precision

If multiple actuating devices are used to shift the beam in multiple directions, then the resolution is improved, but the device size increases

Engineering Contradiction:
Improveimaging resolutionVSAvoiddevice size
Core Design Contradiction:
Manufacturing precisionVSVolume of moving object

Solution Approach 1:

The patent merges the functions of multiple actuating devices into an integrated actuating system that can perform multi-directional beam shifting. By combining first and second actuating modules with different light-transmitting elements into one coordinated system, the invention achieves high-resolution imaging without proportionally increasing device volume, as the modules share common structural support and control systems.

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If multiple actuating devices are used to achieve high-resolution imaging, then the imaging quality is improved, but the device cost increases

Engineering Contradiction:

Solution Approach 1:

The actuating modules in the patent are designed with multi-functionality, where each module can contribute to beam shifting in multiple directions when working in coordination with other modules. This universal design allows the system to achieve high-resolution imaging capabilities without requiring specialized expensive actuators for each specific direction, thereby controlling manufacturing costs while maintaining high imaging quality.

AI summary

A projection device includes: an illumination system providing an illumination beam; a light valve arranged on a transmission path of the illumination beam and converting the illumination beam into an image beam; a projection lens arranged on a transmission path of the image beam and projecting the image beam out of the projection device; a first actuating module connecting and moving a first element, so that the image beam shifts back and forth along at least one of the first, second, and third directions; and a second actuating module connecting and moving a second element, so that the image beam shifts back and forth along at least one of the first, second, and third directions. The first and second directions are perpendicular. The third and first directions form an angle of 45 degrees, so do the third and second directions. The first and second elements are different.
