Fan-Shaped Blind Support Mount for Variable Arc Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional door and window ornamental article positioning structures fail to accommodate fan-shaped blind bodies of varying circumferential sizes, leading to gaps and eventual collapse, which compromises the appearance of the fan-shaped blind body.
Innovation Solution
A support unit with detachable stop plates and a support mount featuring an arcuate support portion that can be individually processed to fit various sizes, combined with wing panels and insert hooks for secure assembly, ensuring stable positioning and maintaining the fan-shaped blind body's appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support mount is integrally molded with a fixed arcuate support portion, then the manufacturing process is simple, but it cannot accommodate fan-shaped blind bodies of varying circumferential sizes, leading to gaps and collapse
Solution Approach 1:
The support mount is divided into multiple components: a body portion, a detachable support portion, and connecting portions. This segmentation allows the support portion to be replaced with different sizes to match various fan-shaped blind bodies, solving the adaptability problem while keeping each component relatively simple in structure.
Solution Approach 2:
The support portion is designed to be detachable and replaceable rather than fixed. This dynamic design enables the support mount to adapt to different circumferential sizes by swapping support portions, resolving the contradiction between simplicity and versatility.
2Manufacturing precision
If the arcuate support portion is fixed in size, then the manufacturing precision is easy to control, but gaps appear when the hollow-out portion size does not match, causing collapse over time
Solution Approach 1:
By separating the support portion from the body portion and making it detachable, the system can achieve precise fits for different sizes by selecting appropriate support portions, thereby improving reliability without sacrificing manufacturing precision control.
Solution Approach 2:
The support portion parameters (circumferential size) can be changed by replacing the support portion with different sizes. This allows the system to maintain high positioning reliability for various fan-shaped blind body sizes while each individual support portion remains simple to manufacture with controlled precision.
3Adaptability or versatility
If a separate support unit is used instead of an integrated support mount, then adaptability to different sizes is improved, but the assembly complexity increases
Solution Approach 1:
The support unit is segmented into modular components (body portion, support portion, connecting portions) that can be easily assembled and disassembled. This modular design provides flexibility for different sizes while keeping the assembly process relatively simple through standardized connection interfaces.
Solution Approach 2:
The body portion serves multiple functions: supporting the fan-shaped blind body, providing connecting portions for attachment, and housing the detachable support portion. This multi-functionality reduces the need for additional components, thereby limiting the increase in assembly complexity.
4Stability of the object's composition
If the support mount is fixed to the door/window frame, then the positioning stability is improved, but it cannot be adjusted or replaced for different blind body sizes
Solution Approach 1:
The support mount is segmented into a fixed body portion (attached to the frame) and a detachable support portion. This allows the body portion to remain stably fixed while the support portion can be replaced for different sizes, resolving the contradiction between stability and adaptability.
Solution Approach 2:
The support portion is designed with dynamic replaceability while the body portion maintains static fixation to the frame. This combination provides both stability (through fixed attachment) and adaptability (through replaceable support portion).

AI summary
A door and window ornamental article positioning device includes a support unit equipped with stop plates and a support mount to be mounted to a central hollow-out portion of a fan-shaped blind body having a counterweight board fixedly attached to the underside of both end sides respectively. The stop plates and the support mount are respectively provided with connecting portions and coupling cavities to be joined to each other with a restricting space formed for the positioning of the fan-shaped blind body therein. The support mount has an arcutate support portion precisely abutting against the hollow-out portion, and wing panels with insert hooks extending at both external sides to engage with insert pieces of the counterweight boards. Via the separate design, the support unit can have a proper support mount assembled thereto to fit to various diameters of the fan-shaped blind body and stably position the central hollow-out portion thereby.
