Projector Foot Pad Rotation Mechanism for Fast Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projection devices have complex foot pad structures that are difficult to operate, leading to time-consuming adjustments of the projection image angle.
Innovation Solution
A projection device design featuring a rotating component and a foot pad component, where the rotating component is arranged at the top of the housing and drives the foot pad component to rotate, allowing for easy adjustment of the projection image angle by changing the height of the housing relative to the foot pad.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional foot pad structures are used, then the projection device can adjust the projection image angle, but the structure becomes complex and difficult to operate
Solution Approach 1:
The foot pad structure is divided into multiple foot pads (first foot pad, second foot pad, third foot pad, fourth foot pad) that can be independently adjusted. Each foot pad has its own adjusting mechanism, allowing separate adjustment of different corners of the projection device, thereby simplifying the overall adjustment process and improving ease of operation.
Solution Approach 2:
The foot pads are designed with dynamic adjusting mechanisms that allow users to easily change the position and angle of each foot pad. The adjusting mechanisms include threaded rods, nuts, and connecting components that enable smooth and flexible adjustment, transforming a static complex structure into a dynamically adjustable system.
2Productivity
If conventional foot pad structures are used, then the projection device can adjust the projection image angle, but the adjustment process becomes time-consuming
Solution Approach 1:
The foot pads are pre-configured with adjusting mechanisms that are ready for quick adjustment. The threaded rods and nuts are pre-assembled in a manner that allows for rapid adjustment without requiring complex assembly steps, thereby reducing the time needed for adjustment while maintaining adjustment capability.
Solution Approach 2:
The dynamic adjusting mechanisms allow for quick and smooth adjustment of foot pad positions. The threaded connection systems enable rapid adjustment by simply rotating the adjusting components, significantly reducing the time required to adjust the projection image angle compared to fixed or complex adjustment mechanisms.

AI summary
A projection device includes a housing, a rotating component, and a foot pad component. The housing has the first and second parts. The second part has a screw hole. The rotating component has an abutting part and a driving part. The abutting part passes through and abuts against the first part. The foot pad component has a foot pad part, a screw rod part, and a driven-to-move part. The screw rod part is connected between the foot pad part and the driven-to-move part and screwed to the second part through the screw hole. The driven-to-move part is in the housing and embedded in the driving part. The rotating component rotates relative to the first part, causing the foot pad component to be driven by the rotating component to rotate relative to the second part, thereby changing a height of the housing relative to the foot pad part.
