Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shutter slat control systems require dismantling the entire shutter to replace a single slat, are costly, and time-consuming to implement, with motorization being difficult due to complex rod and screw mechanisms.
Innovation Solution
A control system with a profile and carrier design allowing sliding connection of the connecting box, featuring open faces and grooves for easy assembly and disassembly, and modular connecting rods with sections for independent assembly, enabling slat replacement without dismantling the entire shutter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the control system uses a rod and connecting rod system with screws in the axis of movable blades, then the shutter provides stable control of slat rotation, but the screws cannot be removed and blades cannot be changed without dismantling the entire shutter
Solution Approach 1:
The control system is divided into modular components: individual connecting boxes for each slat, separate endless screws, and detachable rod sections. This segmentation allows each slat's control mechanism to be independently accessed and replaced without dismantling the entire shutter assembly.
Solution Approach 2:
The connecting boxes are extracted from the traditional integrated rod system and positioned outside the profile at each slat end. This extraction allows the connecting boxes to be easily removed and replaced by accessing them from the outside of the shutter, enabling blade replacement without full dismantling.
2Ease of manufacture
If the control system uses traditional rod and connecting rod mechanisms, then the shutter provides reliable slat control, but the implementation time is long and cost price is high
Solution Approach 1:
The connecting boxes are pre-assembled with the endless screws and rod sections before installation. This preliminary assembly simplifies the final installation process, as the modular units can be quickly attached to the slats without complex on-site assembly, reducing implementation time and costs.
3Extent of automation
If the control system uses endless screws with rod mechanisms for motorization, then the shutter achieves automated slat rotation, but the structure is difficult to motorize and remains complex
Solution Approach 1:
The motorization system is segmented into individual rod sections that can be independently coupled to motors. Each rod section corresponds to a specific slat or group of slats, allowing for modular motorization that simplifies the overall structure while maintaining automation capability.
Solution Approach 2:
The connecting boxes serve as intermediary components between the motors and the slats. They house the endless screws and provide mounting points for the rod sections, simplifying the transmission of rotational motion from motors to slats while reducing structural complexity.
