Modular Roller Blind Control Kit for Tube Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller blind control assemblies are not adaptable to different roller blind tube diameters and mounting bracket designs, requiring replacement of the entire blind assembly when changing the control assembly.
Innovation Solution
A modular kit of parts comprising driven parts with varying diameters and profiles, mounting parts with different securing formations, and a drive part with a housing and rotating mechanism, allowing selection and assembly for specific tube and bracket combinations, along with optional biasing assemblies for rotational assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a control assembly is designed for a specific roller blind tube diameter and mounting bracket design, then the control assembly can be securely mounted and function reliably, but it cannot be adapted to different roller blind tube diameters or mounting bracket designs
Solution Approach 1:
The control assembly is divided into separate modular components: a drive unit, a driven part, and a mounting part. This segmentation allows each component to be independently selected and replaced based on specific requirements, enabling adaptation to different roller blind tube diameters and mounting bracket designs while maintaining reliable connections through standardized interfaces.
Solution Approach 2:
The mounting part is designed with universal features that can accommodate multiple mounting bracket designs through adjustable securing formations. The driven part can be selected in different diameters to match various roller blind tube sizes, allowing a single control assembly design to serve multiple applications across different product lines and manufacturers.
2Reliability
If the entire blind assembly is replaced when changing the control assembly, then compatibility issues are avoided, but material waste increases and environmental sustainability is reduced
Solution Approach 1:
The control assembly components (drive unit, driven part, mounting part) are extracted as separate replaceable modules from the overall blind assembly. This allows only the specific control assembly components to be removed and replaced while leaving the roller blind tube, fabric, and mounting brackets in place, significantly reducing material waste compared to replacing the entire assembly.
Solution Approach 2:
The modular design enables selective discarding of only the worn or obsolete control assembly components while recovering and reusing the majority of the blind assembly including the roller blind tube, fabric, and mounting brackets. This extends the life of the overall blind system and reduces the need for complete replacement.
3Adaptability or versatility
If multiple control assembly variants are manufactured for different tube diameters and mounting bracket designs, then compatibility with various products is achieved, but device complexity and manufacturing costs increase
Solution Approach 1:
By segmenting the control assembly into standardized modules (drive unit, driven part, mounting part), the complexity is distributed across separate components rather than creating entirely different control assembly designs for each application. This modular approach allows compatibility with various tube diameters and mounting brackets through component selection rather than designing multiple complete assemblies.
Solution Approach 2:
The invention merges the functions of different control assembly variants into a single modular platform. The standardized drive unit can be combined with different driven parts and mounting parts to create multiple compatible configurations, reducing the total number of unique components that need to be manufactured and managed compared to having separate control assemblies for each variant.
