Non-Interference Front-Surface Opening Frame with Curved Shaft Groove
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing front-surface opening/closing-type frames face difficulties in assembly, interference with structures during opening, and risk of separation due to external forces, particularly when fixed to building walls, limiting their application to metal furniture and construction frames.
Innovation Solution
A non-interference front-surface opening/closing-type frame design featuring a fixing frame with a protrusion and inward-downward shaft groove, a cover frame with a rotating shaft and compression piece elastically supported by an elastic member, and a connection piece, allowing smooth operation and reduced vertical width for slimness, preventing separation and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cover frame is designed to pass over the base frame or fixing frame during opening, then the opening mechanism is simple, but the cover frame contacts the building structure and is interfered with, making opening difficult
Solution Approach 1:
The patent changes the opening path from a linear horizontal movement to a rotational movement around a shaft. The cover frame rotates around a shaft that extends perpendicular to the opening direction, allowing the cover frame to swing open without contacting the building structure, thus resolving the interference problem while maintaining mechanism simplicity
2Ease of manufacture
If the shaft groove is opened inward and upward, then assembly is simple, but the rotating shaft easily escapes from the shaft groove due to external force
Solution Approach 1:
The patent changes the shaft groove shape from a straight linear groove to a curved groove that follows the rotational path of the rotating shaft. The curved groove with rounded contours prevents the shaft from escaping while maintaining assembly simplicity, as the curved shape naturally guides the shaft into position during assembly
3Stability of the object's composition
If the cover frame is coupled to the fixing frame with a large vertical width, then structural stability is improved, but slimness is compromised
Solution Approach 1:
The patent relocates the coupling mechanism from a vertical arrangement to a horizontal arrangement by extending the shaft perpendicular to the opening direction. This dimensional change allows the cover frame to be coupled to the fixing frame with minimal vertical width while maintaining structural stability through the horizontal shaft connection

Function Achieved in This Case
Facilitates easy assembly and operation without interference, enhances structural stability against external forces, and allows seamless integration with metal furniture and construction frames by preventing contact with building structures during opening.
Implementation Method 1
a compression piece (220) formed sharply inward and downward from the rotating shaft (211) and elastically supported by the elastic member (30)

AI summary
The present invention relates to a structure of a non-interference front-surface opening/closing-type frame, and is advantageous in that, since a cover frame can be conveniently coupled right beneath a fixing frame, assembly of the cover frame and the fixing frame is substantially facilitated, it becomes easier to prevent the cover frame from being separated from the fixing frame by an external impact, and the vertical width between the lower portion of a rotating shaft of the cover frame and the lower portion of a compression piece is substantially reduced, thereby realizing slimness. The present invention is also advantageous in that: the cover frame can efficiently open/close the fixing frame without interference of the fixing frame; escapement of the rotating shaft from the shaft groove can be prevented while the cover frame opens/closes the fixing frame; there is no concern that an elastic member may act as an interfering element during assembly of the fixing frame and the cover frame; and it becomes easier to maintain the state in which the cover frame closes the fixing frame. The present invention is also advantageous in that, when the cover frame opens the fixing frame, the cover frame can open the fixing frame more easily with no concern that the cover frame may contact a structure, such as a building wall body, and be interfered with, thereby substantially facilitating extended application to metal furniture of industrial materials, such as picture frames and door frames, or construction window/door frames.
