Solution Overview

Problem

In micro projectors, the audio play component is typically integrated, leading to poor sound quality when the projector is placed far from the user, as the audio position is fixed relative to the projector.

Innovation Solution

A micro projector with a separable structure where the audio play components are detachably connected to the projection component, allowing them to be placed separately for improved sound quality and flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the audio play component is integrated with the projection component, then the device structure is compact and simple, but the sound quality deteriorates when the projector is placed far from the user

Engineering Contradiction:
Improvedevice structureVSAvoidsound quality
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The audio play component is separated from the projection component into an independent detachable module. This segmentation allows the audio component to be positioned independently near the user while keeping the projection component separate, thereby improving sound quality without compromising structural simplicity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection between the projection component and audio play component is made detachable rather than fixed. This dynamic connection allows the audio component to be moved to different positions relative to the user, enabling optimal sound quality while maintaining a compact integrated structure when needed.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If the audio play component is fixed relative to the projection component, then the device structure is simple, but the flexibility in positioning is reduced

Engineering Contradiction:
Improvedevice structureVSAvoidpositioning flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The audio play component is connected via a detachable mechanism that allows it to be dynamically repositioned. When attached, it forms a simple integrated structure; when detached, it can be positioned flexibly near the user, thus achieving both structural simplicity and positioning adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

By segmenting the audio play component as a separate detachable module, the system gains flexibility in positioning while maintaining structural simplicity through standardized connection interfaces. The modular design allows easy attachment and detachment for different positioning scenarios.

Inventive Principle:
Principle #1Segmentation
