Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current projector mounts lack quick and easy precision adjustment in roll, pitch, and yaw orientations, offer limited security against theft, and are often bulky or difficult to integrate with aesthetic environments.
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 single adjustable friction element for each axis, allowing precise positioning without the need to hold the projector, combined with a key lock for security and tamper-resistant fasteners.
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 separate fasteners into a single integrated fastener that simultaneously secures both pitch and roll adjustments. This single fastener engages with multiple adjustment mechanisms at once, allowing the user to make both pitch and roll adjustments by manipulating only one fastener, thereby reducing adjustment time while maintaining security against theft.
Solution Approach 2:
The single fastener is designed to perform multiple functions: it simultaneously acts as a security fastener against theft and as an adjustment mechanism for both pitch and roll orientations. This multi-functional design eliminates the need for separate fasteners for each adjustment, resolving the contradiction between security and adjustment efficiency.
2Ease of operation
If a single adjustable friction element is used for each axis, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple friction adjustment mechanisms into a single adjustable friction element for each axis. This single element simultaneously controls friction for multiple adjustment operations (pitch and roll), simplifying the user interface to one adjustment control per axis while the internal mechanism handles multiple functions through integrated design.
3Manufacturing precision
If axes of rotation do not extend through the device interface, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the mount structure into distinct functional components: the device interface plate that attaches to the projector, the upright support structure, and the adjustment mechanisms. By separating the axis of rotation from the device interface, each component can be optimized independently for its specific function, improving manufacturing precision while the modular segmentation manages the overall complexity.

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.
