Blind Roller Bracket With Interchangeable Control Mechanisms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional roller blind assemblies are limited in configuration options due to the requirement for specific components, making it difficult to change the placement of control cords from one side to the other without needing additional or custom components.
Innovation Solution
An apparatus that supports two blind rollers from a headrail in one of at least eight configurations using a bracket system with interchangeable control mechanisms and connectors, allowing for flexible placement of control cords on the upper and lower blind rollers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If specific components are designed for a particular configuration, then the assembly achieves proper functional support for that configuration, but the number of possible configurations is limited
Solution Approach 1:
The bracket is designed with multiple engagement projections and recesses that can accommodate different blind control mechanisms in various orientations. The same bracket can secure control mechanisms for upper and lower blind rollers in multiple configurations (at least eight configurations) without requiring different bracket designs, thereby achieving multi-functionality and versatility.
Solution Approach 2:
The bracket incorporates reversible engagement features where control mechanisms can be secured in different orientations (first and second orientations). The engagement projections and recesses allow the assembly to be dynamically configured for different control cord placements (left or right side) without requiring physical reconfiguration of the bracket structure itself.
2Adaptability or versatility
If control cords are installed on the same side of the blinds, then the assembly is simpler to manufacture, but additional or custom components are required if controls need to be on opposite sides
Solution Approach 1:
The bracket is designed with asymmetric engagement features including upper engagement projections and lower engagement recesses that can accommodate control mechanisms in different orientations. This asymmetric design allows control cords to be placed on different sides (left or right) while using the same bracket, eliminating the need for mirrored or custom bracket variants.
Solution Approach 2:
The bracket separates the engagement functions into distinct upper and lower sections with specific projections and recesses. This segmentation allows independent orientation of upper and lower control mechanisms, enabling flexible control cord placement while maintaining a standardized single bracket design for manufacturing.
3Adaptability or versatility
If different component sets are ordered for different configurations, then each configuration is optimized, but the quantity of components to be managed increases
Solution Approach 1:
The bracket serves multiple functions by accommodating different blind control mechanisms (first and second mechanisms) for both upper and lower blind rollers in various configurations. A single bracket design replaces the need for multiple configuration-specific bracket sets, reducing the quantity of different component sets that must be ordered and managed.

AI summary
An apparatus supports two blind rollers from a headrail in one of at least eight configurations. Each blind roller has a first end coupled to a first blind control mechanism and a second end coupled to a second blind control mechanism. The apparatus includes a bracket having a top flange for coupling the bracket to an end of the headrail. An inner face of the bracket has an upper engagement projection configured to secure at least one of: the first blind control mechanism for the upper blind roller in one of two mechanism orientations, and the second blind control mechanism for the upper blind roller. The inner face also has at least two lower engagement recesses, each configured to receive a lower engagement connector, the projection configured to secure at least one of the first blind control mechanism and the second blind control mechanism for the lower blind roller.
