Polyhedral Projector with Detachable Support Plate for Vertical Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing small projectors become unstable when placed vertically, risking falls and instability during use.
Innovation Solution
A polyhedral projector design with a detachable support plate of similar size to one of its surfaces, featuring a central fixing portion to secure a smaller surface as a bottom, allowing the projector to stand alone and maintain stability both horizontally and vertically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projector is placed vertically to enable desktop projection, then the versatility and application scenarios are improved, but the stability of the projector deteriorates causing it to fall down
Solution Approach 1:
The support plate is separated from the main projector body, allowing it to be detached when horizontal placement is needed and attached when vertical placement is needed. This segmentation enables the projector to adapt to different projection scenarios while maintaining stability in each configuration.
Solution Approach 2:
The support plate extends the projector's functionality by adding a vertical placement capability through a third dimension (height/depth). By attaching the support plate to the bottom surface, the projector can be positioned vertically on desks, transforming it from a two-dimensional horizontal placement to a three-dimensional versatile positioning system.
2Ease of operation
If the support plate is detachably attached to allow versatile placement, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The support plate is designed as a detachable component rather than a permanent part of the projector body. This segmentation allows users to easily attach or detach the support plate depending on whether vertical or horizontal placement is needed, improving ease of operation without requiring complex mechanical systems.
Solution Approach 2:
The support plate serves multiple functions: it provides stability for vertical placement, acts as a protective cover for the bottom surface when detached, and can be easily stored when not in use. This multi-functionality justifies the added complexity by delivering multiple benefits from a single component.

AI summary
There is provided a projector comprising: a polyhedral main body portion made up of a plurality of surfaces which includes a projection unit; and a support plate which has substantially the same size as that of a first surface of the plurality of surfaces of the main body portion and which is detachably attached to the first surface, wherein the support plate has in a substantially central portion a fixing portion to which a second surface of the plurality of surfaces which is smaller than the first surface is fixed, and wherein when the main body portion is placed on the support plate in such a way that the second surface functions as a bottom surface, the second surface of the main body portion is fixed to the fixing portion of the support plate, whereby the main body portion is allowed to stand alone.
