Solution Overview

Problem

Existing projectors lack the ability to efficiently adjust their position and orientation to ensure optimal image projection on various surfaces, especially in mobile and outdoor settings.

Innovation Solution

A mobile projector with left and right moving parts and elevating mechanisms, controlled by a processor using sensors, to adjust the projector's position, height, and orientation for optimal image projection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a projector is made mobile and compact for home and outdoor use, then portability and versatility are improved, but the ability to adjust position and orientation for optimal image projection deteriorates

Engineering Contradiction:
ImproveportabilityVSAvoidposition adjustment capability
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the projector body capable of active movement rather than being static. The left and right moving parts enable the projector to autonomously adjust its position and orientation, transforming it from a passive device requiring manual setup to an active system that can dynamically adapt to different projection scenarios, thereby resolving the contradiction between portability and position adjustment capability

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The projector implements self-service through autonomous navigation and self-positioning capabilities. The moving parts enable the device to automatically find optimal projection positions and orientations without requiring manual intervention, allowing a compact portable device to maintain excellent position adjustment capabilities through self-directed movement and adaptation

Inventive Principle:
Principle #25Self-service

2Manufacturing precision

If elevating mechanisms are added to adjust height and orientation, then image projection quality is improved, but device complexity increases

Engineering Contradiction:
Improveimage projection qualityVSAvoidmechanical structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent merges the elevating mechanism with the existing moving parts structure. The left and right elevating parts are integrated into the overall moving system, where the same mechanical components that enable lateral movement also facilitate vertical adjustment. This consolidation allows the device to achieve precise image projection quality through height and orientation adjustment while minimizing the increase in device complexity by reusing and integrating existing structural elements

Inventive Principle:
Principle #5Merging (Combining)
