Projection System Automatic User Identification Setup

Solution Overview

Problem

Existing projection systems require manual adjustments for settings like brightness, contrast, and image size, which can be time-consuming and inconvenient, especially when used by different users with varying preferences.

Innovation Solution

A projection system that communicates with a portable electronic device to automatically project personalized images based on an identification signal, including setup parameters such as brightness, contrast, and image size, using communication methods like Bluetooth or WiFi, and allows for automatic login to network services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual adjustment of projection settings is performed, then the projection apparatus can be configured for different users and scenarios, but the setup time and operational convenience deteriorate

Engineering Contradiction:

Improveprojection settings customizationVSAvoidsetup time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by automatically retrieving and applying pre-configured projection settings based on user identification before the actual projection operation. The projection apparatus automatically determines appropriate settings (brightness, contrast, image size) based on the identified user's preferences, eliminating the need for manual setup time while maintaining adaptability to different users.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The projection apparatus performs self-service by automatically identifying the user and applying appropriate settings without requiring manual intervention. The system autonomously retrieves user profiles and configuration data, processes the projection parameters, and adjusts the projection settings automatically, thereby reducing setup time while maintaining customization for different users.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If manual adjustment of projection settings is performed, then the projection apparatus can be configured for different users and scenarios, but the ease of operation deteriorates

Engineering Contradiction:

Improveprojection settings customizationVSAvoidoperational convenience

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by automatically retrieving and applying pre-configured projection settings based on user identification before the actual projection operation. The projection apparatus automatically determines appropriate settings (brightness, contrast, image size) based on the identified user's preferences, eliminating the need for manual setup time while maintaining adaptability to different users.

Solution Approach 2:

The projection apparatus performs self-service by automatically identifying the user and applying appropriate settings without requiring manual intervention. The system autonomously retrieves user profiles and configuration data, processes the projection parameters, and adjusts the projection settings automatically, thereby reducing setup time while maintaining customization for different users.

Inventive Principle:

Principle #25Self-service

3Extent of automation

If communication connection is established with portable electronic apparatus, then automatic identification and personalized projection is achieved, but device complexity increases

Engineering Contradiction:

Improveautomatic user identificationVSAvoidcommunication and control units

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The projection apparatus incorporates communication units (first communication unit for establishing connections, second communication unit for receiving signals) and control units that serve multiple functions: user identification, setting retrieval, parameter processing, and projection control. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing device complexity while achieving automatic identification and personalized projection.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The projection apparatus acts as an intermediary between the portable electronic apparatus and the projection output. It receives identification signals from the portable device, processes the user profile information, determines appropriate projection settings, and controls the projection unit accordingly. This intermediary role consolidates multiple functions into a single system, managing complexity while enabling automation.

Inventive Principle:

Principle #24Intermediary (Mediator)
