Solution Overview

Problem

Existing awnings lack variability in the inclination of their guide rails, which limits their effectiveness in managing rainwater runoff and adapting to changing sun positions, and can introduce stresses when the fabric is lowered unevenly.

Innovation Solution

The awning features height-adjustable guide rails with coupling elements that allow the front and rear ends of the guide rails to be moved along supports, enabling variable inclination and stability adjustments, with the option for rear ends to be pivotably attached or moved along rear supports for enhanced adjustability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the guide rails are fixed in inclination, then the structure is simple and stable, but the awning cannot adapt to changing sun positions or manage rainwater runoff effectively

Engineering Contradiction:
Improveadjustability of guide rail inclinationVSAvoidcomplexity of height-adjustable coupling elements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The guide rails are designed with height-adjustable coupling elements that allow the inclination of the guide rails to be changed dynamically. The coupling elements can move relative to the guide rails and supports, enabling the system to adapt from a fixed inclination to variable inclinations based on sun position and rainwater management needs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The guide rail system is divided into segments that can be independently adjusted. The coupling elements are separated from the guide rails and supports, allowing independent movement and adjustment of each segment. This segmentation enables the inclination to be modified without affecting the entire structure.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the fabric is lowered on one side to adjust inclination, then the awning can be positioned at different angles, but considerable stress is introduced into the shading system and supports

Engineering Contradiction:
Improveadjustability of fabric inclinationVSAvoidstress in shading system and supports
Core Design Contradiction:
Adaptability or versatilityVSStress or pressure

Solution Approach 1:

Instead of lowering the fabric on one side to adjust inclination, the system uses height-adjustable coupling elements that move along the supports to change the inclination. This dynamic adjustment mechanism distributes the stress evenly across the entire shading system and supports, avoiding the concentrated stress that would result from uneven lowering.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The coupling elements act as intermediaries between the guide rails and the supports. They provide a mechanism for adjusting the inclination without directly transmitting the full weight and stress of the fabric to any single point in the shading system, thereby reducing stress on the supports and fabric.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the front ends of the guide rails are fixed on the front supports, then the installation is simple, but the inclination of the guide rails cannot be varied

Engineering Contradiction:
Improvevariable inclination of guide railsVSAvoidease of installation and adjustment
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The coupling elements are designed to be movable both relative to the guide rails and relative to the front supports. This dynamic design allows the front ends of the guide rails to be adjusted in height along the supports during installation and operation, enabling variable inclination without complicating the manufacturing process.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The coupling elements serve multiple functions: they connect the guide rails to the supports, enable height adjustment, and provide structural stability. This multi-functionality allows the same component to achieve variable inclination while maintaining ease of installation and operation.

Inventive Principle:
Principle #6Universality (Multi-functionality)
