Projector Segmentation for Adjustable Projection Direction

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing projectors are difficult to adjust for image projection direction and position after installation, as they require complex mechanisms to prevent inclination and shifting, limiting the range of angle and position adjustments.

Innovation Solution

A projector design where the power source accommodation section is separate from the projection section body, allowing the projection section to be moved freely for direction adjustments without moving the heavy power source, and is securely attached to a surface using a duct system, reducing the burden on the supporting mechanism and simplifying the structure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the projector is fixed securely to prevent inclination and shift, then the stability of the projector is improved, but the adjustability of the projection direction is worsened

Engineering Contradiction:

ImprovestabilityVSAvoidadjustability of projection direction

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The projector is divided into two separate sections: a power source accommodation section that remains fixed to the surface, and a projection section body that can be freely adjusted. This segmentation allows the heavy power source to be securely anchored while the lighter projection section can be repositioned and reoriented without moving the entire projector, thereby resolving the contradiction between stability and adjustability.

Principle #1Segmentation

2Device complexity

If the power source and projection section are integrated, then the structure is simplified, but the burden on the supporting mechanism increases

Engineering Contradiction:

Improvestructural simplicityVSAvoidburden on supporting mechanism

Core Design Contradiction:

Device complexityVSWeight of moving object

Solution Approach 1:

The projector structure is segmented into a stationary power source accommodation section and a movable projection section body. The power source, which is typically heavy, remains fixed to the surface and does not need to be moved during adjustment. Only the projection section body needs to be moved, significantly reducing the burden on the supporting mechanism while maintaining structural simplicity through modular design.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If the entire projector is moved for direction adjustment, then the projection direction can be changed, but the energy consumption and operational difficulty increase

Engineering Contradiction:

Improveprojection direction changeVSAvoidenergy consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

By separating the projector into a fixed power source section and a movable projection section body, only the lighter projection section needs to be moved for direction adjustment. This eliminates the need to move the heavy power source, thereby reducing energy consumption and operational difficulty while maintaining the ability to change projection direction.

AI summary

A projector includes a power source accommodation section and a projection section body. The power source accommodation section is supported by a duct and accommodates a power source circuit that converts electric power supplied from the duct. The projection section body accommodates a projection section that projects an image, and the projection section body is so supported by the power source accommodation section that a direction in which the image is projected is adjustable.
