Cruiser Awning Window Regulator with Curved Slide Rail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional awnings for open cabins of cruisers require manual operation for opening and closing the window panel, which is cumbersome, and the existing designs are aesthetically unpleasing and prone to operational issues due to temperature deformation of materials.
Innovation Solution
A window regulator system that includes a longitudinally curved roof frame with a lightproof roof cover and a transparent window panel that slides along a constant distance slide rail, connected to a transfer mechanism with driving and driven pulleys and wires, allowing for automatic opening and closing of the window panel without narrowing the cabin space or compromising aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a manual operation grip is provided on the window panel for opening and closing, then the window can be operated, but the operation is cumbersome and requires manual effort
Solution Approach 1:
The patent replaces the manual mechanical operation system with an automatic electrical actuation system. A motor-driven mechanism automatically moves the window panel along the slide rail, eliminating the need for manual gripping and operation while maintaining the sliding mechanism's mechanical simplicity.
2Ease of operation
If a box-type enclosure is constructed with a clear vinyl sheet and fastener, then ventilation is provided, but the enclosure projects from the streamlined body resulting in poor appearance
Solution Approach 1:
The patent employs a dynamic window panel that can slide along the roof frame between open and closed positions. When closed, the panel creates a streamlined profile matching the cruiser's aerodynamic shape. When opened, it provides ventilation while minimizing projection. This dynamic positioning resolves the contradiction between maintaining aesthetic shape and providing ventilation functionality.
3Ease of operation
If the clear vinyl sheet is made open by the fastener for ventilation, then air circulation is enabled, but the sheet deforms due to temperature difference causing operational issues
Solution Approach 1:
The patent changes the material parameter from flexible vinyl sheet to rigid or semi-rigid window panel. This material substitution eliminates temperature-induced deformation while maintaining the ventilation function through the sliding mechanism. The panel's rigidity ensures consistent operation across varying temperature conditions, resolving the reliability issue.
4Shape
If the window panel is made transparent and slidably opening and closing, then the streamlined shape is maintained, but automatic operation is not provided requiring manual grip operation
Solution Approach 1:
The patent integrates an automatic actuation system that replaces manual mechanical operation. The motor-driven mechanism automatically positions the transparent window panel along the slide rail, maintaining the streamlined shape when closed while providing automatic opening and closing functionality without requiring manual grip operation.
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 automatic operation enhances user convenience and maintains the streamlined appearance of the awning while improving the structural strength of the roof frame, ensuring smooth and quiet operation without the risk of wires being caught or causing noise.
Implementation Method 1
four wire rows are inserted into the driving box and the driven box by winding a wire around each of the driving pulleys and each of the driven pulleys provided in front and in rear, respectively, between the driving box and the driven box
Implementation Method 2
the flat driving box bilaterally symmetrically includes driving pulleys having driving shafts vertically, and the flat driven box bilaterally symmetrically includes driven pulleys having driven shafts vertically
