Motorised drive device for a blackout device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized drive devices for concealment devices, such as curtains, require complex and time-consuming installation processes due to multiple fixing devices and lack of easy access for maintenance and energy recharging, leading to increased costs and operational difficulties.
Innovation Solution
A motorized drive device with a single fixing plate that can be easily assembled and disassembled, allowing for simplified installation, maintenance, and access to the energy source, featuring a drive wheel and adjustment mechanism to accommodate various rod types, including round, 'I', 'H', or 'U' sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two fixing devices are used on opposite side faces of the housing, then the motorized drive device can be securely assembled with the rod, but the installation becomes lengthy and complex requiring multiple separate operations
Solution Approach 1:
The patent combines two separate fixing devices into a single integrated fixing plate that attaches to only one side face of the housing. This fixing plate includes two holding devices that extend from it, allowing the motorized drive device to be securely assembled with the rod through a single attachment point rather than requiring separate operations on opposite sides.
2Reliability
If two fixing devices are used on opposite side faces of the housing, then the motorized drive device can be securely assembled with the rod, but the installation requires several separate operations by the user
Solution Approach 1:
The patent combines two separate fixing devices into a single integrated fixing plate that attaches to only one side face of the housing. This fixing plate includes two holding devices that extend from it, allowing the motorized drive device to be securely assembled with the rod through a single attachment point rather than requiring separate operations on opposite sides.
3Reliability
If the motorized drive device is assembled with two fixing devices, then secure mounting is achieved, but access to the motorization unit and electrical energy source is complicated during maintenance
Solution Approach 1:
The patent segments the motorized drive device into two main parts: a fixing plate that remains attached to the rod, and a housing containing the motorization unit and electrical energy source. The housing can be detached from the fixing plate, allowing maintenance personnel to access the motorization unit and recharge the electrical energy source without dismantling the entire assembly or removing components from the rod.
4Ease of operation
If a guide plate with guide wheels is used to guide the motorized drive device along the rod, then guidance is provided, but the installation becomes more complex and time-consuming
Solution Approach 1:
The patent merges the guidance function into the holding devices themselves. The holding devices include guide elements that directly guide the motorized drive device along the rod during movement, eliminating the need for a separate guide plate with guide wheels. This integration maintains the guidance function while simplifying the overall structure and reducing installation time.
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
Simplifies the installation and maintenance of motorized drive devices for concealment systems, reduces costs, and enhances accessibility to the energy source while ensuring compatibility with different rod configurations.
Implementation Method 1
The drive wheel is configured to be brought into contact with a rolling surface of a rod of the concealment device, so as to move the motorized drive device along the rod
