Layered Blind Screens for Independent Light and View Control

Solution Overview

Problem

Traditional blinds do not allow for independent manipulation of light penetration and view transparency, as adjusting light penetration inevitably affects view transparency and vice versa.

Innovation Solution

A layered blinds device with evenly spaced rods that can be adjusted using a spacing mechanism to control light penetration and an alignment mechanism to control view transparency, allowing for independent manipulation of radiation streams at different angles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If traditional blinds are adjusted to alter light penetration, then light penetration is controlled, but view transparency is inevitably influenced

Engineering Contradiction:

Improvelight penetrationVSAvoidview transparency

Core Design Contradiction:

Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The blind system is divided into multiple independent screens (first screen, second screen, third screen) that can be adjusted separately. Each screen manipulates radiation at different angles, allowing independent control of light penetration and view transparency. The first screen handles direct solar light, while subsequent screens handle reflected light at different angles, enabling decoupling of light and view control.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention introduces angular dimensionality by considering radiation streams at different angles (direct solar light, reflected light at various angles). By manipulating screens at different angular positions, the system controls light penetration and view transparency as independent variables, adding a dimensional aspect to traditional blind control.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

3Adaptability or versatility

If multiple screens are added to independently manipulate light and view, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improveindependent manipulation of light and viewVSAvoidnumber of screens and adjustment mechanisms

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each screen in the system serves multiple functions: it manipulates radiation at specific angles, contributes to both light penetration control and view transparency control, and works in conjunction with other screens. The screens are universal components that can be adjusted to handle different radiation angles, reducing the need for specialized components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A layered blinds device having a series of screens of evenly spaced rods held in parallel relation to one another that allow users to manipulate light penetration and view transparency as independent variables and a method for doing the same. A spacing mechanism adjusts the spacing between the screens which controls the light penetration while an alignment mechanism adjusts the alignment of the rods which controls the view transparency. The blinds can be adjusted manually or by a tracking system.
