Two-Piece Owl Head Assembly for Multi-Axis Camera Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scarecrow devices with motorized heads lack the ability to simplify assembly and effectively incorporate internal cameras that can sense motion and follow objects in multiple axes, limiting their functionality in capturing images of approaching individuals or animals.
Innovation Solution
A motorized two-piece scarecrow head with a built-in camera and motion sensor, featuring a swivel and tilt motor assembly, an electronic controller, and a camera lens configured as an eye, allowing the head to move in multiple axes to follow and record motion, enhancing the scarecrow's ability to capture images of proximate objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera and motion sensor are integrated into a motorized scarecrow head, then the functionality to capture and follow motion is improved, but the device complexity increases
Solution Approach 1:
The patent combines the camera, motion sensor, motor assembly, and control circuitry into an integrated head unit. The camera and motion sensor are positioned within the head housing, with the motion sensor detecting motion in the field of view of the camera. The motor assembly integrates both pan and tilt motors with shared mounting structures and control circuits, reducing the number of separate components and simplifying assembly.
Solution Approach 2:
The control circuit serves multiple functions: it processes signals from the motion sensor, controls both pan and tilt motors, and activates the camera. The motor assembly provides both horizontal panning and vertical tilting capabilities through a unified mechanical structure. The head housing serves as both structural support and mounting platform for all components.
2Adaptability or versatility
If a motor assembly with multiple motors is used to enable multi-axis head movement, then the ability to follow motion in multiple axes is improved, but the device complexity increases
Solution Approach 1:
The motor assembly is divided into distinct pan and tilt motor units, each with its own mounting bracket and control circuitry. The pan motor rotates the entire head assembly horizontally, while the tilt motor independently controls vertical movement. This segmentation allows each motor to be optimized for its specific function while maintaining overall system integration through shared control and mounting structures.

AI summary
A scarecrow includes a scarecrow body corresponding generally in shape to a body of a live animal; an assembled hollow scarecrow head of molded plastic construction corresponding in shape to a head of the live animal, the assembled head having a front face portion and a separate rear head portion fixed together to form the head, the front face portion having an aperture at an eye location of the front face portion; a camera having a lens configured as an eye and located at the eye location to appear as an eye of the scarecrow; a motion sensor associated with the camera to sense motion proximate the scarecrow; and a motor assembly mounted to the scarecrow body and the head and configured to move the head in multiple axis.
