Sun and Rain Protection Device with Sliding Guide Rails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sun and rain protection devices are sensitive to wind and loads due to the use of flexible cables or ropes, which compromises their stability and durability.
Innovation Solution
The guide rails of the sun and rain protection device are arranged with one end movable at right angles to the longitudinal profiles and the other end slidably mounted on them, allowing for relative displacement and a stable lowering mechanism without flexible cables, utilizing guide carriages with screw drives or linear drives for adjustment, and a pivotable lever for additional stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flexible cables or ropes are used for lowering the guide, then the structure can achieve simple implementation and ease of operation, but the device becomes susceptible to wind and other stresses, reducing stability and reliability
Solution Approach 1:
The patent replaces the flexible cable or rope system with a rigid mechanical lowering mechanism consisting of guide rails that slide along longitudinal profiles of the supporting structure. This substitution eliminates the flexibility issue while maintaining the lowering function, providing both stability and reliability without sacrificing operational simplicity.
2Reliability
If rigid lowering mechanisms are used instead of flexible cables, then stability and reliability improve, but the device complexity increases
Solution Approach 1:
The guide rails serve multiple functions: they guide the transverse movement of the guide, support the longitudinal profiles for sliding motion, and provide structural rigidity. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving the desired stability.
Solution Approach 2:
The patent designs the lowering mechanism to utilize the existing structural elements of the supporting structure (longitudinal profiles) as guide surfaces. This approach creates a mechanically balanced system where the guide rails naturally follow the structural framework, reducing additional complexity while ensuring stable operation.
3Stability of the object's composition
If the guide rails are fixed rigidly to the supporting structure, then structural stability is improved, but the ability to adjust inclination angle is reduced
Solution Approach 1:
The patent implements a dynamic connection between the guide rails and the supporting structure through pivotable levers that allow relative movement. The guide rails can slide along the longitudinal profiles while maintaining rigid connection at the pivot points, enabling inclination adjustment while preserving structural stability during operation.
Solution Approach 2:
The lowering mechanism is divided into segmented components: the guide rails are separated from the supporting structure by intermediate pivotable levers. This segmentation allows independent movement of each component, enabling inclination adjustment while maintaining overall structural stability through the rigid connection of individual segments.
4Object-generated harmful factors
If the guide can be lowered completely perpendicular to the supporting structure, then water drainage is improved, but the mechanism becomes more complex and less stable
Solution Approach 1:
The guide rails are designed to be movable at their first ends (connected to guide carriages) while the second ends remain articulated to the longitudinal beams. This partial movability allows the guide to achieve a lowered position for water drainage without requiring complete perpendicular movement, thereby limiting mechanism complexity while still improving drainage capability.

Implementation Method 1
each with a vertical threaded spindle and a spindle nut interacting with the threaded spindle
Implementation Method 2
the second end of the guide rail can be articulated to the longitudinal beam of the supporting structure via a pivotable lever. One end of the lever is pivotally connected to the longitudinal beam about a first axis of rotation
