Bracket structure and method of using the bracket structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bracket structures for electric curtains are complicated, inconvenient to operate, and prone to loosening due to swinging deformation of the upper track, with troublesome guide rod manufacturing and assembly.
Innovation Solution
A bracket structure featuring a bracket body with a top plate, rear plate, and locking plate, including guide portions and asymmetrical pressing abutting portions to securely fix the upper track, preventing deformation and simplifying assembly and production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a guide rod is added to cooperate with the guide groove to form a guide mechanism, then the stability of the bracket structure is improved, but the manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The patent removes the guide rod from the bracket structure entirely. Instead, the guide groove is directly formed on the locking plate body, eliminating the need for a separate guide rod component while maintaining the guiding function through the groove's geometry alone.
Solution Approach 2:
The guiding function is merged into the locking plate by directly forming the guide groove on its body. This integration eliminates the need for a separate guide rod and reduces the number of components, thereby simplifying both manufacturing and assembly while preserving structural stability.
2Ease of manufacture
If the bracket structure is simplified to remove the guide rod, then the manufacturing and assembly are easier, but the stability against upper track swinging deformation deteriorates
Solution Approach 1:
The patent employs asymmetrical design in the pressing abutting portions, where the first pressing abutting portion and second pressing abutting portion have different geometries and positions. This asymmetry allows the locking plate to effectively counteract the swinging deformation of the upper track while maintaining a simplified structure without a guide rod.
Solution Approach 2:
The guide groove is pre-formed on the locking plate body with specific geometric characteristics that anticipate and prevent the swinging deformation of the upper track. This preliminary design of the groove geometry ensures stability is built into the structure from the outset, eliminating the need for additional guide rods.
3Reliability
If the pressing abutting portions are made asymmetrical with extended pressing edge, then the prevention of upper track swinging deformation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by making only the specific pressing edge of the second pressing abutting portion asymmetrical and extended, while other portions of the locking plate maintain standard geometry. This localized asymmetry targets the specific area needed to prevent swinging deformation without requiring high precision throughout the entire component.

AI summary
A bracket structure and a method of using the bracket structure are provided. The bracket structure includes a bracket body and a locking plate. The top plate and the rear plate of the bracket body respectively form an upper hook portion and a lower hook portion. The locking plate is movably disposed on the top plate of the bracket body. The locking plate has a locking plate body and a control part, and the locking plate body has a first and a second pressing abutting portion. The upper track is placed between the top plate and the rear plate, so that the bottom of the upper track is placed on the lower hook portion, and the first hook portion of the upper track and the upper hook portion of the bracket body are hooked to each other to temporarily fix the upper track on the bracket structure.
