Double-Layer Shade Positioning for Light and Privacy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional curtains lack the ability to maintain partial light adjustment and privacy simultaneously, limiting the practicality of light control and positioning.
Innovation Solution
A double-layered, light-adjustable shade structure with staggered light shielding and transmitting parts, equipped with positioning devices and linking parts, allowing for independent adjustment of light transmission and shielding through a slider and moving block mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the curtain is fully unfolded to achieve complete light blocking, then privacy is improved, but the ability to maintain partial light adjustment is lost
Solution Approach 1:
The curtain is divided into multiple independent curtain clothes that can move relative to each other along the horizontal track. Each curtain can be positioned independently, allowing some curtains to be fully unfolded for privacy while others remain folded to permit light entry, thus resolving the contradiction between complete light blocking and partial light adjustment capability
Solution Approach 2:
The curtain system transitions from a static fully unfolded or fully folded state to a dynamic configuration where each curtain can be independently positioned at different locations along the track. This dynamic positioning capability allows the system to adapt between complete light blocking and partial light adjustment based on user needs
2Illumination intensity
If the curtain is folded to allow light penetration, then light adjustment is improved, but privacy function is lost
Solution Approach 1:
By segmenting the curtain into multiple independently controllable units, the system allows selective positioning where light-permitting curtains can be folded while privacy-maintaining curtains remain unfolded, enabling simultaneous light penetration and privacy protection
Solution Approach 2:
Different portions of the curtain system can have different states (folded or unfolded) according to local requirements. Some areas can be configured for light penetration while adjacent areas maintain privacy, allowing localized optimization of both light adjustment and privacy functions
3Device complexity
If conventional sliding frames are used for lateral movement, then structural simplicity is improved, but positioning precision and stability are worsened
Solution Approach 1:
The conventional purely mechanical sliding frame system is replaced with a hybrid system incorporating magnetic positioning mechanisms. The magnetic attraction between oppositely polarized surfaces provides precise positioning and stable holding without requiring complex mechanical locking structures, thereby improving positioning precision while maintaining structural simplicity
Solution Approach 2:
A magnetic field is introduced as an intermediary force between the curtain and the track structure. The magnetic positioning mechanism uses magnetic attraction to achieve precise positioning and stable holding of the curtain at desired locations, eliminating the need for complex mechanical positioning components

AI summary
A light-adjustable shade structure includes a top beam, a plurality of dimmable curtains, and a plurality of positioning devices. The top beam is provided with a plurality of tracks, the tracks are respectively equipped with a sliding seat connected and driven by each other. The dimmable curtains are staggered from top to bottom with a plurality of light shielding parts and a plurality of light transmitting parts, the dimmable curtains are wound and connected respectively between an upper shaft rod and a lower shaft rod to form a double-layer structure. The positioning devices are installed on the dimmable curtain to adjust the dimmable curtain to form In the transparent or light-shielding state. The dimmable curtain is pushed, pulled, or closed along the trail of the top beam, and the effect of adjusting light can be achieved by staggering or facing the light shielding part and the light transmitting part.
