Projector Focusing Arrangement TRIZ Cases

A helical bearing converts SMA wire-driven rotation into translation, reducing actuator length along the motion axis for smaller designs.

An actuator moves the image sensor with the target velocity to cut blur, wobble, and aliasing in fast borescope imaging.

A reflective light path and adhesive-backed foreign substance trap help preserve image clarity while supporting autofocus and stabilization.

Guide grooves set at 20° to 30° and uneven parting-line arcs keep lens barrels coupled under impact and prevent cam pin separation.

Compact open springs in the lens-module gap cut spring diameter penalty while separate magnetic forces improve pop-out motion and focusing.

Metal-reinforced guide rails and low-friction rolling surfaces reduce deformation and vibration while keeping autofocus and image stabilization smooth.

Two magnetic sensors and summed detection signals suppress noise magnetic fields to keep autofocus lens position detection accurate.

A variable-width blade driving hole and inclined driving pin reduce drop-induced deformation and prevent aperture driving failures.

A ball-supported prism and integrated drive assemblies simplify periscope lens OIS and focusing while improving stability and miniaturization.

Separate coil-magnet pairs and ball-guided lens motion enable compact OIS while limiting magnetic interference in slim camera modules.

By overlapping magnets with the tilting guide, this camera actuator saves OIS space, improves tilt accuracy, and limits magnetic interference.

Shape memory alloy wires move and support the image sensor for autofocus, stabilization, and tilt correction without springs, magnets, or coils.

Static friction holds a camera lens position without continuous SMA energizing, cutting power use while preserving stable movement.

An eight-wire SMA layout uses offset connections and inclined wire geometry to improve autofocus and image stabilization in compact cameras.

A lateral support and driver layout keeps AF and OIS actuators from protruding, preserving folded camera performance in thinner devices.

Guide groove angles and parting-line geometry strengthen barrel coupling, preventing pin separation and lens instability under impact.

By merging chip wiring into the moving substrate, this anti-shake camera module saves space, supports miniaturization, and maintains stable motion control.

A polymer actuator shifts the housing for OIS while the coil drives autofocus, reducing camera module height, drooping, and magnetic interference.

Preemptive lens movement to a preset position cuts optical zoom delay while preserving high-definition image capture in dual-camera devices.

A three-surface coil frame removes bending regions to cut lens position dispersion, simplify manufacturing, and keep the lens stable without power.

Dynamic contrast thresholds tied to focus setting and lighting trigger autofocus only when needed, reducing focus hunting and user distraction.

Adaptive focus lens drive speed uses image plane movement coefficients to improve autofocus accuracy without unnecessary delay.

A split terminal and 3D pad layout make PCB soldering easier while preventing disconnection in shock-prone mini camera modules.

A shared electromagnetic drive moves the lens and rotates the aperture blades, reducing camera module size, weight, and mechanism interference.

Alternating Ti-rich and Ti-lean layers raise spring strength, improve etching, and reduce settling in autofocus camera modules.

An elastic lens barrel and driving unit compensate for hand shake to reduce peripheral image distortion and improve image stability.

Separate focus and shake-correction actuators keep magnet-coil positions stable during lens movement, improving image stability and clarity.

Injection-molded integration of the wire layer and coil into the housing removes assembly steps, lowers cost, and improves positioning accuracy.

Piezoelectric prism tilting reduces friction, corrects hand-shake vibration, and maintains lens alignment for autofocus and zoom.

Thicker wires in a sensor-shift OIS camera improve current supply, resist deformation, and reduce heating while keeping image stabilization reliable.

A damper at the AF rotation restrictor absorbs contact shock between movable and fixing parts, reducing shake without enlarging the camera module.
