Solution Overview
Problem
Existing shading devices lack dynamic control and are often complex and expensive, failing to provide reliable and cost-effective solar protection and temperature regulation.
Innovation Solution
A shading device utilizing a combination of strands and loops, where upper strands are taut for fixed shade and lower strands are slack to modulate shade based on wind conditions, without sensors or motors, allowing for adjustable shading that optimizes solar protection and temperature regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dynamic shading control is added to shading devices, then shading adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies the Dynamics principle by transforming a traditionally static shading device into a dynamic one through the introduction of flexible links that enable automatic movement. The shading element can now adapt its configuration in response to environmental conditions (wind, sunlight), providing dynamic shading control without requiring complex motorized systems or sensors. The flexible links allow the structure to move and reconfigure itself, achieving adaptability through passive mechanical response to environmental forces.
2Extent of automation
If sensors and motors are added for climate control, then shading control precision is improved, but manufacturing cost increases
Solution Approach 1:
The patent applies the Self-service principle by designing a shading device that automatically responds to environmental conditions without requiring external control systems. The flexible links enable the structure to self-adjust its configuration based on wind forces and sunlight angles, eliminating the need for sensors, motors, and control electronics. This passive self-regulating mechanism achieves effective climate control while keeping manufacturing costs low and the system simple to produce.
3Stability of the object's composition
If fixed shading structure is used, then structural stability is improved, but shading modulation capability deteriorates
Solution Approach 1:
The patent applies the Segmentation principle by dividing the shading structure into modular components connected by flexible links. Rather than a single rigid fixed structure, the shading element is segmented into multiple sections that can move independently relative to each other. This segmentation allows the structure to maintain overall stability while enabling local adjustments and modulation of shading capacity in response to environmental conditions.
