Projector Stand Mount With Rotary Base for Stable Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector support bases are difficult to attach to tripods due to the need to rotate the entire support base, which is cumbersome and requires heavy stationary portions to prevent falling, especially when supporting heavy projectors.
Innovation Solution
A projector apparatus with a base that is rotatable relative to a table about a first rotational axis, featuring a coupling unit with a stand mounting portion and a hinge mechanism that allows easy attachment of a stand, such as a tripod, without requiring rotation of the entire support base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the stationary portion is made heavy to prevent the support base from falling, then the stability of the support base is improved, but the ease of operation deteriorates because it becomes difficult to rotate the entire support base to attach the stand
Solution Approach 1:
The support base is divided into a stationary portion and a rotary portion that can rotate independently. The stand mounting portion is located on the rotary portion, allowing the stand to be attached by rotating only the rotary portion rather than the entire heavy support base. This segmentation enables easy operation while maintaining the stability provided by the heavy stationary portion.
2Adaptability or versatility
If the entire support base is rotated to attach the stand, then the stand can be mounted, but the device complexity increases and the ease of operation deteriorates
Solution Approach 1:
The support base is segmented into a stationary portion and a rotary portion with independent rotation capability. The stand mounting portion is positioned on the rotary portion, enabling stand attachment through rotation of only the rotary portion. This reduces the complexity of the mounting operation compared to rotating the entire support base.
Solution Approach 2:
The rotary portion acts as an intermediary mechanism between the stationary support base and the stand. It provides a dedicated interface for stand attachment and rotation, simplifying the overall mounting process while maintaining the structural integrity of the stationary portion.
3Adaptability or versatility
If the stand mounting portion is located on the table, then the stand can be attached, but the stability deteriorates because the table rotates with the base, causing play and image shaking
Solution Approach 1:
The support structure is segmented into a stationary portion that remains fixed and a rotary portion that rotates. The stand mounting portion is located on the rotary portion, which can rotate independently relative to the stationary portion. This allows the table to remain stable on the stationary portion while the rotary portion provides rotation capability, eliminating the play and shaking that would occur if the entire table rotated.

AI summary
A projector apparatus includes a table having a penetrating portion, a base coupled to the table so as to be rotatable relatively to the table about a first rotational axis orthogonal to an installation surface on which the table is installed, a coupling unit erected from the base, a projector coupled to the coupling unit, and a stand mounting portion which is disposed on a surface at the installation surface side in the base, located in the penetrating portion and to which a stand is mounted.
