Vertical Blind Motor Assembly Layout for Hidden Bracket Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized vertical Venetian blind assemblies face challenges in mounting heavy or long motor assemblies to the headrail without requiring additional brackets, which increases length and visibility, limiting installation options and increasing costs.
Innovation Solution
A motorized vertical Venetian blind assembly with an elongated motor assembly that includes a supplementary drive shaft extending parallel to the headrail, creating a space for mounting brackets and allowing for closer installation to windows, while using narrow motors and optional cover housings to protect and secure the assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the motor assembly is mounted to the rear wall of the head rail at the end location, then the motor assembly can be hidden from sight, but no space is available for mounting brackets and the blind cannot be properly supported
Solution Approach 1:
The patent extends the motor assembly in the longitudinal direction beyond the head rail end, creating a supplementary space that allows mounting brackets to be positioned without compromising the hidden aesthetic appearance when the blind is in its normal position. This dimensional extension resolves the contradiction by providing mounting capability while maintaining visual concealment.
2Strength
If additional mounting brackets are added to support heavy or long motor assemblies, then sagging is prevented, but the length and visibility of the assembly increases
Solution Approach 1:
The patent combines the motor assembly extension with the mounting bracket positioning, where the extended motor assembly housing itself serves as the mounting structure. This integration provides structural support for heavy assemblies without requiring separate additional brackets that would increase overall length and visibility.
3Ease of operation
If the motor assembly is mounted to the face end of the head rail, then mounting space is available, but the assembly length increases and covering is compromised
Solution Approach 1:
Instead of extending mounting capability along the head rail length, the patent extends the motor assembly in the longitudinal direction beyond the head rail end. This dimensional change provides mounting accessibility without increasing the head rail length or compromising the covering function.
4Ease of operation
If special combination brackets are used for mounting, then mounting and dismounting is enabled, but additional cost and inventory complexity is created
Solution Approach 1:
The patent designs the motor assembly extension to serve multiple functions: it provides structural support for mounting, enables bracket attachment, and maintains aesthetic concealment. This multi-functionality eliminates the need for special combination brackets, reducing parts inventory complexity while maintaining full mounting functionality.
