Poster Frame Stand With Rotatable Cover And Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame stands for posters often suffer from issues such as water and dust contamination, limited poster size compatibility, and cumbersome manipulation, especially when trying to align and insert end bars into recesses.
Innovation Solution
A frame stand design featuring a base plate and a cover frame with a rotatable connection, allowing easy insertion and removal of posters without adhesives, and incorporating a locking mechanism for secure closure and handling convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a V-shape frame stand with two hinged frames is used, then the structure is simple and easy to manipulate, but the poster is liable to be contaminated by water and dust and the poster size is limited
Solution Approach 1:
The patent applies a cover frame that acts as a protective enclosure, similar to a flexible shell concept, to seal the poster from environmental contaminants. The cover frame closes over the top opening to prevent water and dust from reaching the poster while maintaining the simple V-shape structure.
2Device complexity
If a V-shape frame stand with fixed frame size is used, then the structure is simple, but only posters with designated size can be inserted and extra tapes or adhesive are needed for smaller posters
Solution Approach 1:
The patent introduces a rotatable cover frame that can be opened and closed dynamically. This allows the frame to adapt to different poster sizes by adjusting the opening angle, enabling posters of various dimensions to be inserted without requiring additional attachment materials while maintaining structural simplicity.
3Reliability
If an A-shape frame stand with removable frame is used, then posters can be held in a taut position and without adhesive, but the manipulation is relatively troublesome especially when two end bars have to be aligned and inserted into the recesses
Solution Approach 1:
Instead of inserting components into recesses as in the prior art, the patent inverts the approach by having the cover frame rotate over the top and close onto the poster from above. This eliminates the alignment and insertion difficulty while maintaining reliable poster holding through the closing action of the cover frame.
4Reliability
If a locking mechanism is added to the frame stand, then the cover frame can be securely closed and handling is facilitated, but the device complexity increases
Solution Approach 1:
The locking mechanism is designed to be self-actuating through the rotational motion of the cover frame itself. As the cover frame rotates closed, its weight and motion automatically engage the locking elements, eliminating the need for separate manual locking operations while maintaining secure closure and avoiding excessive complexity.
