Rotating Mounting Plate for Roller Shutter Shaft Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roller shutter box end wall designs offer limited freedom of action during assembly, making handling and alignment of the roller shutter shaft and mounting plate cumbersome.
Innovation Solution
The mounting plate can be freely rotated about the shaft axis after initial insertion into the receiving formation, allowing for independent alignment and easy positioning of the roller shutter shaft, with radial projections and undergrip areas facilitating rotational displacement and secure fixation, enabling multiple angular orientations and easy disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the mounting plate is fixed in a specific alignment during assembly, then the positioning precision is improved, but the ease of operation deteriorates due to limited freedom of action
Solution Approach 1:
The mounting plate is designed to transition from a fixed alignment state during operation to a dynamically rotatable state during assembly. The receiving formation allows the mounting plate to rotate freely about the shaft axis before final fixation, enabling workers to achieve precise alignment through rotation while maintaining ease of operation during the assembly process.
2Ease of operation
If the mounting plate can be freely rotated during assembly, then the ease of operation is improved, but the manufacturing precision deteriorates due to potential misalignment
Solution Approach 1:
The receiving formation is designed with radial projections and undergrip areas that guide the mounting plate into the correct alignment position before final fixation. The radial projections engage with the undergrip areas to automatically establish the proper angular relationship between the mounting plate and end wall, ensuring precision is achieved before the mounting plate is fully fixed.
3Adaptability or versatility
If multiple alignment positions are available, then the adaptability is improved, but the device complexity increases due to additional fixing mechanisms
Solution Approach 1:
The system provides multiple fixed alignment positions through the interaction of radial projections and undergrip areas on the receiving formation. These positions are achieved through simple rotational movement of the mounting plate about the shaft axis, without requiring complex switching mechanisms or additional fixing devices. The dynamics of rotation combined with discrete engagement positions provides adaptability while maintaining simplicity.

AI summary
The combination has a roll loading shaft fastenable at an assembly board (15) with a gear box (10) or a drive motor. A receiving molding (23) with undercut areas (25) is formed at a front wall (7). The molding is arranged at the assembly board for retracting radial projections below the undercut areas, where the assembly board is fixed to the front wall. The assembly board is inserted into the receiving molding and freely rotated about a shaft axis (x) before the insertion into the receiving molding. The assembly board comprises multiple radially running oblong holes.
