Rotatable Projector Connection Mechanism for User Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projectors with integrated image output devices face operational challenges due to fixed DVD input section positions, leading to reduced usability when installed at positions other than directly in front of the user, such as rear or side installations.
Innovation Solution
A projector design featuring a connection mechanism with a plate-like member and rotatable member allows for adjustable positioning of the projector main body relative to the image output device, enabling the operation section to be oriented towards the user while maintaining a flexible installation configuration, and includes a rotation stopping mechanism for temporary fixation at desired angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the DVD input section is fixed to the opposite side of the projection side, then the structure is simple and stable, but the operationality is lowered when the projector is located at positions other than directly in front of the user
Solution Approach 1:
The connection mechanism incorporates a rotatable member that enables the projector main body to rotate relative to the image output device. This dynamic capability allows the DVD input section to be repositioned from a fixed opposite-side location to various orientations, including positions facing the user directly, thereby improving operationality while maintaining a relatively simple overall structure.
Solution Approach 2:
The connection mechanism is divided into distinct components: a plate-like member fixed to one device, and a rotatable member with a rotation stopping mechanism attached to the other device. This segmentation allows independent rotation and positioning of the projector main body relative to the image output device, enabling the operation section to be oriented toward the user while keeping the structural changes localized and manageable.
2Adaptability or versatility
If the projector main body is mounted on the image output device via a fixed connection, then the structure is stable, but the freedom of installation is reduced
Solution Approach 1:
The connection mechanism transitions from a completely fixed rigid connection to a semi-dynamic connection where the projector main body can rotate relative to the image output device. The rotation stopping mechanism provides stable positioning at selected angles, combining the flexibility needed for various installation positions with the stability required for secure mounting.
Solution Approach 2:
The rotatable member acts as an intermediary component between the projector main body and the image output device. It mediates the connection by allowing rotational movement while maintaining mechanical coupling, enabling the projector to be installed in various positions (front, rear, right, left) while remaining structurally stable when positioned at desired orientations.
3Ease of operation
If the operation section is positioned far from the user, then the projection can be placed at various positions, but the operationality of the projector is lowered
Solution Approach 1:
The rotatable connection mechanism enables the projector main body to be rotated so that the DVD input section, initially positioned on the opposite side of the projection side, can be reoriented to face the user directly. This dynamic repositioning reduces the effective distance between the operation section and the user, improving operationality without requiring physical relocation of the entire projector system.
