Segmented Light-Shielding Wall for Selective Privacy and Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic blinds control entire walls or windows, leading to enclosed spaces when in a light shielding state, and do not allow individuals in one space to view specific areas in another space effectively.
Innovation Solution
A light shielding device with a controllable wall comprising multiple panels that can switch between light transmission and shielding states, using optical path specification and control units to manage panel states based on specified positions, allowing selective visibility and concealment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electronic blind controls the entire wall or window to be in a light shielding state, then privacy is improved, but the space becomes enclosed and undesirable areas cannot be selectively hidden
Solution Approach 1:
The light shielding wall is divided into multiple independently controllable panels, allowing selective control of different regions. Each panel can be independently switched between light transmission and shielding states, enabling precise control over which areas are visible or hidden while maintaining overall privacy when needed.
Solution Approach 2:
Different panels on the light shielding wall are assigned different functional states based on local requirements. Some panels maintain light transmission for openness while others switch to shielding for privacy, creating localized quality variations that satisfy both contradictory requirements simultaneously.
2Adaptability or versatility
If a light shielding region is provided only at the line of sight of a walking person, then the state of being enclosed is relieved, but a person present in the conference room is unable to look out through the shielded region
Solution Approach 1:
The light shielding wall dynamically adjusts panel states based on detected observer positions and optical paths. When no observers are present or when viewing is desired, panels switch to light transmission state, providing openness and viewing capability simultaneously through real-time adaptation.
Solution Approach 2:
The system uses optical path detection and observer position monitoring to provide feedback for controlling panel states. This feedback mechanism enables the wall to automatically adjust between openness and shielding based on actual viewing conditions, resolving the contradiction between maintaining openness and enabling viewing.
3Adaptability or versatility
If multiple panels are independently controlled based on optical paths, then selective hiding and viewing is achieved, but device complexity increases
Solution Approach 1:
The light shielding wall system performs self-control by automatically detecting optical paths and observer positions, then autonomously adjusting panel states without requiring manual intervention. This self-service capability reduces operational complexity while maintaining high adaptability for selective concealment and viewing.
Solution Approach 2:
The control system integrates multiple functions including optical path detection, observer position monitoring, and panel state control into a single universal system. This multi-functional approach consolidates complexity into one integrated system rather than requiring separate mechanisms for each function.
