Window Blind Frame Sagging Prevention via T-Bracket Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Window blind frames secured to large windows often experience sagging or drooping due to inadequate support, particularly at the top frame element when a window blind is coupled to the frame.
Innovation Solution
A window blind frame design featuring a top and bottom two-part component with T-shaped brackets and a supporting member that connects these components, providing additional structural support to prevent sagging, along with corner brackets and cover plates for secure attachment and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the top frame element is made as a single component, then the structure is simpler, but the frame sags or droops when secured to large windows
Solution Approach 1:
The top frame element is divided into two separate components that are joined together using a corner bracket. This segmentation allows the frame to maintain stability on large windows while keeping the overall structure manageable. The corner bracket acts as a connector that reinforces the joint between the two components, preventing sagging without requiring the entire frame to be overly complex.
2Stability of the object's composition
If additional supporting members and T-shaped brackets are added, then frame stability is improved, but device complexity increases
Solution Approach 1:
Instead of uniformly reinforcing the entire frame structure, the patent applies additional supporting elements (T-shaped brackets and supporting members) only at critical locations where sagging is most likely to occur. The T-shaped brackets are positioned at the corners and midpoints of the top frame element, providing localized reinforcement exactly where needed to prevent sagging, rather than increasing complexity throughout the entire frame.
3Stability of the object's composition
If the top frame element is divided into two parts, then sagging is prevented, but manufacturing and assembly complexity increases
Solution Approach 1:
The top frame element is segmented into two separate components that can be manufactured independently using standard fabrication processes. This segmentation allows each component to be produced using conventional methods without requiring specialized equipment or complex tooling. The corner bracket serves as a simple connector that joins these two components, making the assembly process straightforward despite the divided structure.
Solution Approach 2:
The two separate top frame components are merged together using a corner bracket that provides both structural support and alignment. This merging approach allows the components to be manufactured separately (simplifying production) while still achieving the stability of a reinforced structure when assembled. The corner bracket acts as an intermediate element that combines the two components into a unified, stable frame element.
