Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing projection devices require users to pause the projection and manually adjust the device to change the projection direction, which is inconvenient and can lead to collisions or impacts, especially when the device is not designed for easy rotation or miniaturization.

Innovation Solution

A projection device featuring a turntable module with a first and second turntable, where the projection module is fixed to the second turntable, allowing for independent rotation and projection functionality, enabling smooth 360° rotation without pausing the projection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the projector is moved to change projection direction, then the projection direction can be changed, but collision or impact may occur and operation is inconvenient

Engineering Contradiction:

Improveconvenience of changing projection directionVSAvoidcollision or impact

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The projector is divided into two independent machine bodies: a stationary base unit and a rotatable projection unit. The projection unit can be independently rotated to change projection direction without moving the entire projector, thus avoiding collision while maintaining operational convenience.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The projection unit is designed with rotatable joints and flexible connections, allowing dynamic adjustment of projection direction. This enables the projection unit to change orientation smoothly without rigid movement that could cause impact, resolving the contradiction between ease of operation and avoidance of collision.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If the machine bodies are rotated relative to each other to change projection direction, then projection direction can be altered, but the projection must be paused making operation inconvenient

Engineering Contradiction:

Improveconvenience of changing projection directionVSAvoidcontinuity of projection

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The projector is segmented into a stationary base unit containing the light source and a separately rotatable projection unit containing the projection lens. This segmentation allows the projection unit to be adjusted independently without interrupting the light source operation, enabling continuous projection during direction changes.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The projection unit is pre-configured with all necessary optical components and is designed to rotate as a complete functional unit. This preliminary configuration allows the unit to be rotated without pausing the projection process, as the rotation mechanism is integrated into the functional design rather than requiring operational interruption.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If a suspension arm is used to pivot the projector for rotation, then projection direction can be changed, but the suspension arm occupies a lot of space contradicting miniaturization trends

Engineering Contradiction:

Improveability to rotate projectorVSAvoidspace occupied by suspension arm

Core Design Contradiction:

Ease of operationVSVolume of moving object

Solution Approach 1:

The rotation mechanism is nested within the projector body itself, with the projection unit integrated into the base unit through compact rotational joints. This nesting eliminates the need for external suspension arms, reducing the overall volume while maintaining the ability to change projection direction.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

Instead of using a large external suspension arm for rotation, the invention implements rotation within the internal structure of the projector through multi-axis rotational joints. This dimensional reorganization allows rotation functionality to be achieved within a compact footprint, avoiding the space requirements of traditional suspension arm designs.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
