Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection devices face challenges in projecting large images without requiring a tall casing or additional brackets, as the lens needs to be elevated, which increases costs and installation complexity.
Innovation Solution
A projection device with a main casing and a supporting assembly that flips to allow the projection lens to face different directions, enabling projection onto a standing surface without a tall casing or additional bracket, using a pivotal connecting mechanism and a reflection mirror to adjust the projection path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the lens is disposed at a high position on the casing to enable large image projection, then the projection capability is improved, but the casing size in the height direction must be large
Solution Approach 1:
The supporting assembly is designed to be movable between a folded state (leaning against the main casing) and an unfolded state (standing on the surface), allowing the lens to dynamically adjust its height and projection angle. This dynamic structure enables large image projection without requiring a permanently tall casing.
Solution Approach 2:
The invention changes the projection geometry by unfolding the supporting assembly to stand on the surface, which alters the spatial dimension of projection. The projection lens can then project images onto surfaces at different angles and distances, achieving large image capability through dimensional transformation rather than just increasing casing height.
2Adaptability or versatility
If a bracket is additionally added to elevate the projector for large image projection, then the projection capability is improved, but the device complexity and cost increase
Solution Approach 1:
The supporting assembly integrates multiple functions: it serves as both the support structure for the lens and the elevation mechanism. By merging the support function and elevation function into a single integrated assembly that flips from folded to unfolded state, the invention eliminates the need for separate brackets while maintaining large image projection capability.
Solution Approach 2:
The supporting assembly is designed to be movable between a folded state (leaning against the main casing) and an unfolded state (standing on the surface), allowing the lens to dynamically adjust its height and projection angle. This dynamic structure enables large image projection without requiring a permanently tall casing.
3Adaptability or versatility
If a bracket is additionally added to elevate the projector for large image projection, then the projection capability is improved, but the installation becomes laborious
Solution Approach 1:
The supporting assembly is designed to be movable between a folded state (leaning against the main casing) and an unfolded state (standing on the surface), allowing the lens to dynamically adjust its height and projection angle. This dynamic structure enables large image projection without requiring a permanently tall casing.
Solution Approach 2:
The supporting assembly automatically transitions between folded and unfolded states through its hinge connection, eliminating the need for complex installation procedures. The structure self-adjusts to provide the required elevation and projection angle without requiring additional brackets or laborious assembly steps.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible projection onto various surfaces without the need for a tall casing or additional brackets, allowing for convenient use and cost-effective implementation while maintaining a compact form factor.
Implementation Method 1
the supporting assembly disposed on the main casing in a flipping manner. When the projection device housing is located in a folded position, the supporting assembly leans against the main casing and the projection lens faces a first direction. When the projection device housing is located in an unfolded position, the supporting assembly is flipped with respect to the main casing and is adapted to stand on the surface, and the projection lens faces a second direction

AI summary
A projection device is adapted to be placed on a surface and includes a projection lens and a projection device housing. The projection lens is connected to the projection device housing, and the projection device housing includes a main casing and a supporting assembly disposed on the main casing in a flipping manner. When the projection device housing is located in a folded position, the supporting assembly leans against the main casing and the projection lens faces a first direction. When the projection device housing is located in an unfolded position, the supporting assembly is flipped with respect to the main casing and is adapted to stand on the surface, and the projection lens faces a second direction and is adapted to project onto the surface. The projection device may project onto the standing surface without a tall casing or a bracket to be included or additionally assembled.
