Projectors TRIZ Cases

A protrusion-mounted angle conversion member keeps the phosphor rod tip from tilting when foreign matter enters the support groove.

Curved reflective and powered transmission surfaces shrink mirror spacing in a projector optical layout while preserving aberration correction and resolution.

Projected indexes and camera-detected markers create a shared reference frame, simplifying projector-camera calibration while preserving position accuracy.

Rotatable anamorphic lenses pre-distort projection images to match DCI aspect ratios, improving pixel use and brightness in dual-format cinema systems.

Visual overlay of projection and installable ranges on a space image helps plan projector placement accurately without manual measurement.

A camera-projector whiteboard uses feedback masking to block reprojected image regions, enabling natural remote annotation without visual loops.

A dichroic mirror and polarization beam splitter separate fluorescence from reflected excitation light to preserve pure projected color output.

Sensor-based surface sizing automatically scales projected human images to life size, avoiding manual installation adjustment.

Polarization beam splitting lets four LCOS image paths splice in parallel while reducing reflector-induced surface errors and easing alignment.

A back-surface diffusion region on the phosphor wheel suppresses return blue light, reducing color mixing in projection light sources.

An incident-angle-adjusted light guide and phosphor layout limits blue leakage and helps projectors maintain the target white-light balance.

Shifted image-forming cycles and synchronized dual-wavelength LCD illumination reduce projector color breakup during rapid eye movement.

Interchangeable character bodies with built-in memory expand projector story themes and audio-image content without complex cartridges or SD cards.

Time-varying P- and S-polarized blue laser output suppresses projector speckles while preserving illumination and image clarity.

Tri-color lasers, a wavelength converter, and a segmented dichroic mirror improve illumination homogeneity while preserving projector brightness.

Using CIE Yu′v′ encoding and extra primaries, this case expands display gamut, improves color accuracy, and preserves RGB compatibility.

A split-reflection optical path reuses blue and phosphor-converted light paths to shrink projector light sources and reduce speckle and fringes.

Multiple main and branch refrigerant paths improve heat transfer in compact exchangers for cooling high heat-generating elements.

A single housing with multiple lenses and laser emitters projects different or synchronized content in several directions with lower power and less hardware.

A display screen replaces motors and film slides to project seamless dynamic ambient images with lower cost and synchronized light-audio effects.

Redirected projection beams map video onto a continuous spherical dome, surrounding multiple viewers for a more immersive visual experience.

A wavelength converter and diffusion layer merge blue and fluorescent light paths to shrink projector optics and reduce speckle noise.

A meta-atom optical element creates different powers in orthogonal directions to shape beam intensity and angle in a smaller, temperature-stable package.

Combined light source output and image data correction reduces color shading and brightness unevenness when the projection range shifts.

Interchangeable reflection optics vary image shift from the optical axis, enabling short-focus oblique large-screen projection in a compact layout.

Blue light is parallelized into the light guide end face to prevent side leakage, preserve yellow-blue balance, and improve projector white light output.
