Dual-Socket Motor Assembly for Roller and Non-Roller Blinds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor assemblies for blinds are limited in versatility and can only be used for motorizing roller blinds, lacking the ability to efficiently drive other types of blinds without adaptation.
Innovation Solution
The motor assembly includes a second socket on the output shaft, allowing it to securely engage and drive non-roller blinds, featuring a polygonal or rectangular cavity with a frustoconical section, and a transmission system with a coupling that ensures proper torque adaptation and fastening, enabling the motorization of various blind types without modification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a motor assembly is designed exclusively for roller blinds, then it can provide specialized drive mechanism for roller blinds, but it cannot be used for non-roller blinds without adaptation
Solution Approach 1:
The motor assembly is designed with dual sockets on its output shaft - a first socket for receiving the drive member of a roller blind and a second socket for securing a non-roller blind to the rolling shaft. This multi-functional design allows the same motor assembly to drive both roller and non-roller blinds without requiring adaptation or modification, directly resolving the contradiction by enabling versatility while maintaining a unified structural design
2Adaptability or versatility
If separate motor assemblies are provided for roller and non-roller blinds, then each blind type can receive optimized drive mechanism, but it increases inventory complexity and cost
Solution Approach 1:
Instead of providing separate motor assemblies for roller and non-roller blinds, the invention integrates both connection types into a single motor assembly design. The output shaft incorporates both a first socket for roller blind drive members and a second socket for non-roller blind attachment, eliminating the need for multiple motor assembly variants and reducing inventory complexity while maintaining specialized drive capabilities for each blind type
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
The motor assembly can seamlessly operate both roller and non-roller blinds, providing a versatile solution that eliminates the need for separate motor assemblies, ensuring efficient and adaptable blind operation.
Implementation Method 1
a rotary motor (4)
Implementation Method 2
a transmission, and in particular a reducing gear, to react and adapt the torque delivered by the rotary motor
Implementation Method 3
a coupling inserted between the rotary motor and the transmission and ensuring the proper torque take-up between the rotary motor and the transmission
Implementation Method 4
the output shaft comprising a first socket for receiving a drive member of the rolling shaft of a roller blind
Implementation Method 5
the output shaft further includes a second socket, separate from the first socket, for securing a non-roller blind to the rolling shaft
