Adjustable Projection Screen Mounting Without Wall Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ultra-short focus projection systems, installing a large projection screen on a wall damages the wall and requires labor-intensive adjustments, making it time-consuming and destructive.
Innovation Solution
A projection screen supporting device with a bracket body, supporting assembly, and adjustable projection screen hanging assembly, allowing the screen to be installed without damaging the wall, featuring parallel standing poles, traversing poles, and adjustable hanging pieces for secure and precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the projection screen is installed by puncturing holes directly through the wall, then the installation process is simple, but the wall is damaged and cannot be reused
Solution Approach 1:
The patent introduces a supporting device as an intermediary between the wall and the projection screen. This device includes a bracket body with supporting legs that rest on the ground, and a hanging assembly that suspends the screen without penetrating the wall. The intermediary device transfers the load from the screen to the ground through the supporting legs, eliminating the need to puncture the wall while maintaining secure screen support.
2Adaptability or versatility
If the projection screen position needs to be adjusted by puncturing the wall again, then the screen can be repositioned, but the process is time-consuming and labor-intensive
Solution Approach 1:
The patent incorporates adjustable components in the hanging assembly, including movable clamps and adjustable brackets that can be repositioned along the supporting structure without requiring wall punctures. The supporting legs can be adjusted in length and position, allowing the screen to be relocated easily by simply reconfiguring the movable components of the supporting device rather than making permanent modifications to the wall.
3Ease of manufacture
If the projection screen is installed on the wall, then the installation is straightforward, but irreparable destructive marks are left on the wall
Solution Approach 1:
The supporting device serves as a mediator that eliminates direct contact between the installation process and the wall surface. The bracket body with its supporting legs creates a separate support structure that rests on the ground, and the hanging assembly attaches the screen to this intermediate structure rather than to the wall itself, thereby preventing any destructive marks on the wall while maintaining installation ease.
4Object-affected harmful factors
If a bracket body with supporting assembly is used to support the projection screen without damaging the wall, then the wall remains intact, but the device structure becomes more complex
Solution Approach 1:
The supporting device is divided into distinct functional modules: a bracket body, multiple supporting legs with adjustment mechanisms, and a hanging assembly with movable components. This segmentation allows each component to perform its specific function independently and enables easy assembly and disassembly. The modular structure reduces overall complexity by making the system more manageable and easier to install compared to a monolithic complex structure.
