Insect Roller Screen with Integrated Weight Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic opening screen devices face challenges with difficult installation and maintenance, large overall dimensions, and the inability to create modular screens with multiple doors due to the placement of mobile weights and wire tensioning elements.
Innovation Solution
The mobile weight is housed directly inside an upright, allowing it to move between raised and lowered positions to automatically open the screen, eliminating the need for external wire elements along the stepping plane and enabling easier disassembly and modular designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If mobile weights are housed in external lateral compartments, then the automatic opening function is achieved, but the overall width dimensions of the framework become considerable
Solution Approach 1:
The mobile weight is nested inside the mobile upright structure, with the weight housed within the upright's internal cavity. This integration eliminates the need for external lateral compartments, significantly reducing the overall width of the framework while maintaining the automatic opening function through gravitational action of the weight.
Solution Approach 2:
The weight housing function is merged with the mobile upright structure itself. The upright serves dual purposes: as a structural support element and as a containment housing for the mobile weight, thereby eliminating separate external compartments and reducing overall device width.
2Extent of automation
If external lateral compartments are provided for housing weights, then automatic opening is enabled, but installation and maintenance become difficult
Solution Approach 1:
The device is segmented into modular components where the mobile upright with integrated weight housing can be independently assembled and disassembled. The screen panel, mobile upright, and fixed upright are separate modules that can be easily connected and disconnected, facilitating simple installation and maintenance without requiring complex disassembly of external weight compartments.
3Stability of the object's composition
If wire tensioning elements run along the lower side of the screen, then the screen structure is stabilized, but the passage for user transit is obstructed and installation is complicated
Solution Approach 1:
The wire tensioning elements are relocated from the horizontal lower side of the screen to the vertical upright structures. The wires now run vertically along the uprights and connect at the upper ends, transferring the stabilization function to the vertical dimension and clearing the horizontal passage area for unobstructed user transit.
4Shape
If wire elements are concealed in fixed guides along the stepping plane, then the aesthetic appearance is improved, but the disassembly process is complicated
Solution Approach 1:
The wire tensioning elements are extracted from the fixed guides along the stepping plane and relocated to the upright structures. This extraction eliminates the need for complex disassembly of concealed wiring during maintenance, while the wires remain properly routed and secured along the uprights for a clean appearance.
5Extent of automation
If the screen device uses fixed compartments for weights, then the automatic opening mechanism works, but modular assemblies with several doors cannot be provided
Solution Approach 1:
The mobile upright with integrated weight housing is designed as a universal modular component that can be independently configured for each door unit. Multiple uprights with their self-contained weight mechanisms can be assembled together to create modular screen systems with several doors, allowing flexibility in configuration while maintaining automatic opening functionality in each module.
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 solution results in a compact, easily maintainable automatic opening screen device with reduced overall dimensions and the capability to create modular assemblies with multiple doors, simplifying installation and disassembly while maintaining automatic operation.
Implementation Method 1
The fall of the weight 16 generates the motion of the upright 11 which houses the same thus automatically opening the device
