Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing external venetian blind systems require on-site assembly, which is time-consuming and costly due to the need for site-specific installation and distribution of electromotive drive elements, and lack a compact preassembly solution for the motor control unit and venetian blind motor.
Innovation Solution
An external venetian blind device with a preassembled motor control unit and venetian blind motor, where the motor control unit is integrated into the motor housing, allowing for factory pre-assembly and eliminating the need for on-site structural measures, using a compact control housing to protect electronic components and reduce material costs through a single connection cable for energy sourcing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the motor control unit and venetian blind motor are assembled separately on-site, then the installation can be adapted to external conditions of the building, but the assembly time and material costs increase significantly
Solution Approach 1:
The motor control unit is pre-assembled with the venetian blind motor in a factory setting, creating a pre-assembled unit that can be installed as a single component. This preliminary assembly action eliminates on-site assembly requirements while maintaining installation flexibility through standardized mounting interfaces on the motor housing.
2Productivity
If the motor control unit is preassembled with the venetian blind motor in the factory, then assembly time and material costs are reduced, but the device complexity increases
Solution Approach 1:
The motor control unit is physically integrated with the venetian blind motor by mounting it directly on the motor housing. This merging of previously separate components into a single integrated unit simplifies the overall system structure and reduces the number of assembly steps required during installation.
3Adaptability or versatility
If multiple cable connections are used for electrical connections between components, then the electrical connections are more flexible, but the space requirements and material costs increase
Solution Approach 1:
The electrical connections between the motor control unit and the venetian blind motor are extracted from the external cable connection domain and integrated into the internal structure of the pre-assembled unit. This extraction eliminates the need for multiple external cables, reducing space requirements while maintaining electrical connection functionality through internal wiring.

AI summary
The device (10) has a Venetian blind motor (30) including a motor housing to be fastened to an upper rail (22), and a motor controlling unit (44) including an electrical accumulator i.e. radio receiver, and arranged at the housing. An external energy source (54) i.e. solar energy source (54'), is connected with a charge controller, and a receiving element receives an external input signal to lift, lower or turn a vertically stacked lamella (14). A motor controller is fed by the accumulator, and receives a control signal from the accumulator to control and feed the motor. The external energy source is selected from the solar energy source and 12V battery such as car battery.
