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 adjustment mechanisms. This single fastener engages with corresponding receptacles that control multiple degrees of freedom, allowing the projector to be securely mounted against theft while enabling quick adjustment of multiple parameters by loosening just one fastener.
Solution Approach 2:
The single fastener design serves multiple functions: it secures the pitch adjustment, secures the roll adjustment, and provides a unified release mechanism for both. The receptacles are designed to engage this single fastener in a way that simultaneously controls multiple adjustment degrees of freedom, making the fastener universal for multiple security and adjustment functions.
2Volume of moving object
If a compact mount design is used, then aesthetic appearance is improved, but adjustment range may be limited
Solution Approach 1:
The patent employs dynamic adjustment mechanisms that allow the projector to be positioned across a wide range of angles and orientations within a compact mount structure. The pitch and roll adjustment mechanisms are designed with sufficient travel range to accommodate various projection scenarios while maintaining a low-profile compact appearance when in use. The mount can adapt to different projection distances and screen positions without requiring a bulky structure.
3Ease of manufacture
If the projector weight is not balanced on the mount, then installation is simpler, but the mount pulls out of adjustment position
Solution Approach 1:
The patent incorporates a balancing mechanism that counteracts the projector's weight to maintain precise adjustment positions. The pitch and roll adjustment mechanisms include friction control or locking features that provide counterbalancing forces to hold the projector steady at any desired angle. This allows the mount to maintain manufacturing precision and adjustment stability without requiring complex counterweight structures, as the balancing is achieved through controlled friction and mechanical advantage in the adjustment mechanisms.

Implementation Method 1
a single selectively adjustable friction element for any one or all of the first, second, and third portions of the support structure interface to frictionally resist shifting of the device interface about the first, second, or third, axes of rotation
Implementation Method 2
A projector mount with a device interface and orientation adjustment structure that includes multiple axes of rotation, a geared adjustment mechanism

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.
