Adjustable Roller Blind Bearing Support for Slat Size Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller shutter designs face limitations in flexibility regarding roller shutter length and slat size selection, which restricts the adjustment of the winding drum's position relative to the guide rail, affecting assembly and security features.
Innovation Solution
The bearing supports are connected to the guide rail via an angle arrangement with adjustable guide means, allowing for longitudinal adjustment and fixation, and stop elements are similarly adjustable via another angle arrangement, enabling optimal positioning and use with different slat sizes without altering the structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bearing support is rigidly connected to the guide rail, then the structure is simple and stable, but the flexibility in adjusting the winding drum position and selecting slat sizes is limited
Solution Approach 1:
The bearing support is made adjustable along the guide rail through a slot-hole mechanism with positioning pins, allowing the vertical position of the winding drum to be dynamically changed according to different roller shutter lengths and slat sizes, transforming a rigid structure into an adaptable one
Solution Approach 2:
The connection between the bearing support and guide rail is segmented into discrete adjustable positions through the slot-hole positioning mechanism, enabling independent adjustment of the winding drum position while maintaining overall structural integrity
2Ease of operation
If the winding drum is positioned closer to the guide rail, then the roller shutter winds up more compactly, but the stop elements cannot be optimally positioned for security
Solution Approach 1:
The stop elements are made independently adjustable relative to the bearing support through another slot-hole positioning mechanism, allowing their position to be optimized for security while the bearing support position is optimized for winding efficiency
Solution Approach 2:
The positioning system is segmented into two independent adjustment mechanisms: one for the bearing support position and another for the stop element position, allowing simultaneous optimization of both winding and security functions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for optimal adjustment of the winding drum's position and stop elements, enhancing flexibility and ease of use across various roller shutter sizes, simplifying assembly and security features while maintaining structural integrity.
Implementation Method 1
the upper end of the roller shutter facing the winding drum is connected to the winding drum via spring leaves
Implementation Method 2
the guide and clamping bolts of the first guide means are designed as clamping screws which can be screwed into threaded holes which are attached to the angled leg of the rail, which penetrate the longitudinal slot and the screw head of which is supported on the edge areas of the longitudinal slot

AI summary
A roller shutter (2) can be wound onto and unwound from a winding drum (1) which is rotatably mounted on bearings (3) on both sides. Each bearing (3) is attached to a bearing support (4), which is connected to a guide rail (8). Stop elements (14) are attached to the bearing supports (4) and project above the winding drum (1) into the plane formed by the lowered roller shutter (2) held in the guide rails (8). When the lowered roller shutter (2) is pushed up, the upper end of the roller shutter (2), guided by spring leaves, comes to rest against these stop elements (14). The respective bearing support (4) is connected to the guide rail (8) via an angle bracket (7). The angle bracket (7) has first guide elements along which the bearing support (4) can be adjusted longitudinally along the guide rails (8) and fixed in the set position.This allows the winding drum (1) to be positioned optimally with respect to the guide rails (8).
