Portable Projection System with Hinged Folding Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector systems are cumbersome and lack mobility, requiring predefined mounting and occupying valuable space, while also needing to be transportable for temporary use in various locations such as military, homeland security, and corporate functions.
Innovation Solution
A portable projection system with collapsible frame components, including hinged vertical and horizontal members, and a projector mounting assembly that allows for easy disassembly and reassembly, enabling the system to be folded into a compact configuration for transport and set up in different locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the projector is mounted on a mobile caddy in the room, then the projector can be easily positioned, but valuable floor space is occupied
Solution Approach 1:
The patent transitions from floor-mounted projection to ceiling-mounted projection, utilizing the vertical dimension (ceiling space) instead of horizontal floor space. This allows the projector to be positioned above the seating area, eliminating the need for floor occupancy while maintaining easy positioning capability through the ceiling mounting structure.
2Area of stationary object
If the projector is ceiling mounted, then floor space is saved, but the wiring and mounting are predefined and lack mobility
Solution Approach 1:
The patent divides the projection system into separate modular components: a portable projector unit, a detachable mounting bracket, and a ceiling mount assembly. This segmentation allows the system to be easily assembled and disassembled, providing mobility while maintaining ceiling mounting benefits. The mounting bracket can be attached to different ceiling locations, enabling repositioning without permanent installation.
3Adaptability or versatility
If the display system is made portable and transportable, then mobility is improved, but the structure becomes more complex
Solution Approach 1:
The patent combines the projector, mounting bracket, and support structure into an integrated portable assembly. The mounting bracket is designed to attach directly to the projector housing, and the ceiling mount components are unified into a single transportable unit. This merging reduces the number of separate parts and simplifies the overall structure while maintaining portability and ease of setup.
4Reliability
If the projector mounting assembly includes support structures, then stability is improved, but the device complexity increases
Solution Approach 1:
The mounting bracket is designed as a multi-functional component that serves multiple purposes: it provides structural support for the projector, enables ceiling mounting, allows for positional adjustment, and facilitates easy attachment and detachment. By consolidating these functions into a single universal bracket design, the patent achieves stability without proportionally increasing complexity.
