Motorized Door Screen Assembly With Horizontal Pull-Bar Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing window and door cover systems, such as shades and screens, often require manual operation and lack efficient automation for light control, and do not provide effective barriers against pets, bugs, or environmental ingress.
Innovation Solution
A motorized door shade assembly with a housing, gear system, and pull bar mechanism that allows horizontal movement of a shade screen, utilizing springs and a motor for automated operation, and incorporating pet-resistant, water-resistant, and bug-proof materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual operation is used for shade and screen systems, then device complexity is reduced, but ease of operation and automation capability deteriorate
Solution Approach 1:
The patent combines the shade and screen into a single integrated assembly that operates together through one motorized system. The screen and shade are stacked and move in unison, eliminating the need for separate manual operations and reducing overall system complexity while achieving automation.
Solution Approach 2:
The motorized assembly provides multiple functions through a single system: it operates both the screen and shade simultaneously, providing automated light control, insect protection, and privacy functions. This multi-functionality reduces the need for separate manual systems.
2Productivity
If vertical up and down movement is used for shade screens, then device complexity is simplified, but speed of operation and productivity deteriorate
Solution Approach 1:
The patent transitions from traditional vertical movement to horizontal lateral movement for the screen assembly. This dimensional change allows the screen to slide quickly across the door opening, enabling faster ingress and egress while maintaining a relatively simple track-based mechanism.
3Reliability
If standard materials are used for shade screens, then manufacturing cost is reduced, but resistance to pets, bugs, and environmental factors deteriorates
Solution Approach 1:
The patent employs specialized composite materials for the screen that provide enhanced durability and resistance to pets, bugs, and environmental factors. These composite materials combine different properties to achieve superior performance while maintaining manufacturability through established fabrication processes.
4Illumination intensity
If the shade screen is extended outward, then light control capability is improved, but obstruction of view and space utilization deteriorates
Solution Approach 1:
The patent designs the retracted screen assembly to nest within the door frame or housing structure. When not in use, the screen folds or retracts into the door thickness, eliminating visual obstruction and maximizing the glass area for viewing while maintaining full light control capability when extended.
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
Enables convenient, automated light control with horizontal movement for faster access, while providing protection against pets and bugs, and maintaining an unobstructed view when retracted.
Implementation Method 1
an electric motor to open and close the shade or screen
Implementation Method 2
Two or more springs biased to pull the pull bar
Implementation Method 3
The motor operates a gear assembly to open and close a shade screen via a pull bar
Implementation Method 4
the housing contains a roller to roll and unroll the shade screen when transitioning between an extended position and a retracted position
Data Source
AI summary
A motorized door shade assembly is disclosed, including a housing containing a motor. The motor operates a gear assembly to open and close a shade screen via a pull bar. Two or more springs biased to pull the pull bar, the pull bar moving along a track system configured to lock a zipper into at least one track. The pull bar moves horizontally to open and close the shade screen.
