Projection Screen Bracket with Sliding Hanging Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ultra-short focus projection systems, the installation of projection screens on walls often results in damage to the walls due to the need for puncturing and subsequent adjustments, which is time-consuming and labor-intensive.
Innovation Solution
A projection screen supporting device with a bracket body and hanging pieces that allow for adjustable and secure installation of the projection screen without damaging the wall, using slideways and connection pieces for precise positioning and locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the projection screen is installed on the wall by puncturing holes, then the projection screen can be securely fixed, but the wall is damaged and cannot be easily adjusted
Solution Approach 1:
The patent introduces a supporting device as an intermediary between the projection screen and the wall. This supporting device includes a bracket body with standing poles and traversing poles that can be positioned without puncturing the wall, while still providing secure fixation for the projection screen through hanging pieces and connection mechanisms.
2Ease of operation
If the projection screen position is adjusted on the wall, then the display position can be optimized, but the wall is punctured again which is time-consuming and labor-consuming
Solution Approach 1:
The supporting device incorporates dynamic adjustment mechanisms including sliding connections between hanging pieces and standing poles, and adjustable connection pieces that can be positioned at different locations on the bracket body. This allows the projection screen position to be adjusted by moving components rather than puncturing the wall again, significantly reducing installation time and labor.
3Ease of manufacture
If installation holes are arranged through the wall, then the projection screen can be mounted, but irreparable destructive marks are left on the wall
Solution Approach 1:
The patent extracts the fixation function from the wall itself and transfers it to the supporting device. The bracket body and hanging pieces provide the fixation capability independently, eliminating the need to puncture the wall for mounting holes. This allows the wall to remain intact while still achieving secure projection screen installation.
4Stability of the object's composition
If a rigid fixed installation is used, then the projection screen is stable, but the installation process is complex and damaging
Solution Approach 1:
The supporting device is segmented into multiple independent components including bracket body, standing poles, traversing poles, hanging pieces, and connection pieces. Each component can be independently positioned and adjusted, providing stability when assembled while simplifying the installation process compared to rigid fixed installation methods.
