Innovation Solution

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

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users manually operate operation units to set up tiling or stacking projection, then projection functionality is achieved, but user operational burden increases

Engineering Contradiction:
ImproveUser operational burdenVSAvoidNumber of settings operations
Core Design Contradiction:
Ease of operationVSDevice complexity

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 (tiling or stacking) without requiring users to manually navigate menus or configure settings. The system serves itself by autonomously identifying the projection scenario and executing the corresponding mode.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The projector performs preliminary detection of other projectors and their projection images before the user completes setup. By automatically identifying the projection environment and determining the optimal mode in advance, the system prepares the projection configuration before user interaction is needed, eliminating the need for manual setting operations.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If multiple menu items are provided for projection modes, then functionality is comprehensive, but user operation steps increase

Engineering Contradiction:
ImproveProjection mode optionsVSAvoidTime to select projection mode
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The projector automatically detects other projectors and determines the appropriate projection mode (tiling or stacking) in advance, before the user needs to make a selection. This preliminary automatic determination eliminates the time required for users to navigate through multiple menu items and select the appropriate projection mode.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the projection environment for the presence of other projectors and their images, using this feedback to automatically determine the appropriate projection mode. The feedback loop between environmental detection and mode selection eliminates manual intervention while maintaining adaptability to different projection scenarios.

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If manual configuration is required for projection superimposition, then precise control is achieved, but setup time increases

Engineering Contradiction:
ImproveProjection alignment precisionVSAvoidSetup time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The projector automatically detects other projectors and their projection images, then autonomously determines the optimal projection mode and alignment configuration before user setup is complete. This preliminary automatic configuration achieves precise projection alignment without requiring users to spend time on manual adjustment operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The projector autonomously performs the detection, determination, and configuration of projection alignment parameters without user intervention. The system serves itself by automatically achieving precise projection superimposition based on environmental detection, eliminating the time users would otherwise spend on manual alignment operations.

Inventive Principle:
Principle #25Self-service
