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

VSEngineering 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

Engineering Contradiction:
Improveinstallation adaptabilityVSAvoidassembly time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

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.

Inventive Principle:
Principle #10Preliminary action

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

Engineering Contradiction:
Improveassembly productivityVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improveelectrical connection flexibilityVSAvoidspace requirement
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.
