Solution Overview

Problem

Existing projection technologies require users to perform multiple settings and operations for stacking and tiling projections, which is cumbersome and burdensome.

Innovation Solution

A projector system that determines communicable coupling with another projector and projects a guide image to facilitate the operation of partially superimposing projection images, reducing the need for manual user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manually operate operation units to perform settings for stacking projection or tiling projection, then the projection function can be achieved, but the user burden increases and operation becomes troublesome

Engineering Contradiction:

Improveoperation simplicityVSAvoidsettings time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The projector automatically detects the presence and projection images of other projectors in the environment, and autonomously determines the appropriate projection mode (stacking or tiling) without requiring manual user input. The system performs self-configuration by detecting overlapping projection areas and automatically setting the projection mode accordingly, eliminating the need for users to manually operate settings.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The projector continuously monitors the projection environment by detecting other projection images and their positions. Based on this feedback information about overlapping areas and relative positions, the system dynamically adjusts and determines the optimal projection mode automatically, creating a closed-loop control system that adapts to environmental changes.

Inventive Principle:

Principle #23Feedback

2Extent of automation

If the projector automatically detects and projects guide images, then user burden is reduced, but device complexity increases

Engineering Contradiction:

Improvedetection automationVSAvoidsystem complexity

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The patent introduces a guide image as an intermediary visual element that facilitates automatic detection and user understanding. The guide image is projected onto the projection surface to visually indicate the detected projection mode and alignment status, serving as a mediator between the automatic detection system and the user, while also aiding the system's own detection process.

Inventive Principle:

Principle #24Intermediary (Mediator)
