Solution Overview
Problem
Current projector mounts lack quick and easy precision adjustment in roll, pitch, and yaw orientations, offer limited security against theft, and have a bulky design, making them inconvenient for use in presentation settings.
Innovation Solution
A projector mount with a device interface and orientation adjustment structure that includes multiple axes of rotation, a geared adjustment mechanism, and a key lock system, allowing for precise positioning and theft deterrence while maintaining a compact size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate fasteners are used for pitch and roll adjustments, then security against theft is improved, but adjustment time and complexity increase
Solution Approach 1:
The patent combines multiple adjustment functions into a single integrated mechanism. Specifically, a single friction element controls both pitch and roll adjustments simultaneously, eliminating the need for multiple separate fasteners. This merging maintains security through the friction lock while dramatically reducing adjustment time and operational complexity.
Solution Approach 2:
The friction element serves multiple functions: it acts as both a pitch adjustment mechanism and a roll adjustment mechanism, while also providing theft resistance. This multi-functional design allows one component to replace what would traditionally require several separate components, resolving the contradiction between security and ease of adjustment.
2Volume of moving object
If a compact mount design is used, then aesthetic harmony and space efficiency are improved, but adjustment range and capability are reduced
Solution Approach 1:
The patent employs dynamic adjustment mechanisms that allow the compact mount to achieve full pitch, roll, and yaw adjustment ranges despite its small size. The friction-based continuous adjustment system enables unlimited angular ranges without requiring bulky mechanical structures, maintaining both compactness and full adaptability.
3Reliability
If security fasteners requiring special tools are used, then theft deterrence is improved, but ease of operation for legitimate users is reduced
Solution Approach 1:
The patent changes the parameter of security from mechanical complexity (special tool requirements) to physical principle (friction). The friction element provides theft deterrence through adjustable frictional force that can be easily controlled by hand, eliminating the need for special tools while maintaining both security and ease of operation for legitimate users.

AI summary
A mount for attaching a projection device to an overhead structure includes a device interface operably attachable to the projection device and a device orientation adjustment structure operably coupled with the device interface. The device orientation adjustment structure has structure defining up to three independent axes for adjustment of projector pitch, roll, and yaw. A single selectively adjustable friction element may be provided to enable projector position to be fixed about for any one or all of the independent axes. A gear adjustment mechanism may be provided to enable fine adjustment of projector position. Moreover, any one or all of the independent axes may pass through the projector device, preferably proximate its center of gravity so that it is self balanced on the mount to ease adjustment.
