Solution Overview

Problem

Existing lighting systems for illuminating rooms using daylight do not allow for optimal, individual control of light distribution within multiple rooms, as they lack adjustable reflective surfaces to effectively guide and regulate light.

Innovation Solution

A device featuring a light shaft with adjustable light deflection modules, comprising lamellae with reflective surfaces, which can be manually or computer-controlled to direct and regulate light distribution to individual rooms, utilizing a vertical or horizontal light shaft with transparent or translucent sections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If fixed reflective mirrors and lenses are used to guide light, then light can be directed to rooms, but individual control of light distribution is not possible

Engineering Contradiction:
Improveindividual control of light distributionVSAvoidlighting system structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The lighting system is segmented into multiple independent light deflection modules, each controllable separately. Each module contains adjustable reflective surfaces that can be independently positioned to direct light to specific rooms, enabling individual control of light distribution while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from fixed reflective surfaces to dynamically adjustable ones. The light deflection modules incorporate movable reflective elements that can change their orientation and position, allowing the lighting configuration to be adapted individually for each room without requiring a completely complex reconfigurable system.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If adjustable light deflection modules are added to enable individual room lighting control, then optimal individual lighting is achieved, but device complexity increases

Engineering Contradiction:
Improveindividual lighting control for multiple roomsVSAvoidlight shaft system structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The light deflection modules are designed as universal components that can serve multiple functions: they can direct light to different rooms, adjust light intensity by varying the reflective surface angle, and be positioned at different heights in the light shaft. This multi-functionality reduces the need for separate specialized components for each control function, thereby limiting the increase in overall device complexity.

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

Solution Approach 2:

The adjustable reflective surfaces are nested within compact light deflection module housings that are themselves positioned within the light shaft structure. This nested arrangement allows the adjustable mechanisms to be integrated into the existing light shaft framework without requiring substantial additional space or structural complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

In an apparatus for illuminating rooms, with a light shaft (2; 2') having reflecting inner walls (3), an inlet opening (5; 45) for daylight is provided at one end of said light shaft. Subsections (11, 12, 13; 41, 42, 43) of the light shaft walls are transparent or translucent. Light deflection modules (21, 22, 23; 57) for deflecting the light in different directions are arranged in the region of these transparent or translucent subsections (11, 12, 13; 41, 42, 43), said light deflection modules (21, 22, 23; 57) each comprising a number of laminations (25, 26, 27), which have, at least partially, a reflecting surface. The quantity of light determined for the individual rooms can therefore be regulated in a simple manner, as desired.
