Solution Overview

Problem

Existing screen illumination devices installed on screens often provide limited flexibility in illumination direction, which can restrict user preferences for comfortable reading or working environments.

Innovation Solution

A screen illumination device with a body comprising a first and second housing, where the second housing is detachably connected to the first housing, allowing for the emission of two distinct light beams in different directions, enabling users to adjust the illumination style according to their needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single light source is used in the screen illumination device, then the device structure is simple, but the illumination direction flexibility is limited

Engineering Contradiction:
Improvedevice structureVSAvoidillumination direction flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The illumination device is segmented into a first housing containing a first light source and a second housing containing a second light source. Each housing can be independently configured to emit light in different directions, allowing the device to provide multi-directional illumination while maintaining a modular and relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If the second housing is permanently connected to the first housing, then the structural stability is high, but the user cannot adjust the illumination style

Engineering Contradiction:
Improvestructural stabilityVSAvoidadjustability of illumination style
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The connection between the first housing and second housing is designed to be detachable rather than permanent. This dynamic connection allows users to adjust or remove the second housing according to their illumination needs, providing flexibility in illumination style while maintaining structural stability when the housings are connected.

Inventive Principle:
Principle #15Dynamics
