Solution Overview

Problem

In a system where a server controls multiple projectors, the server's load increases with the number of projectors, as it needs to monitor and manage their operating states, leading to inefficiencies in controlling projector operations.

Innovation Solution

A projector with a display control section that acquires display data including equipment control information from a server and controls other equipment based on this information, allowing for autonomous operation and reduced server load.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a server controls the operation of multiple projectors, then centralized control capability is improved, but the server's load increases with the number of projectors

Engineering Contradiction:
Improvecentralized control capabilityVSAvoidserver load
Core Design Contradiction:
Ease of operationVSPower

Solution Approach 1:

The control system is segmented into multiple independent control units, each projector having its own control unit that can autonomously execute control instructions. This distributes the control load from a single server to multiple projectors, reducing the server's processing burden while maintaining centralized control capability through the control unit that receives instructions from the information processing device.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A control unit is introduced as an intermediary between the information processing device and the projector. This control unit receives control instructions from the information processing device and executes them locally, acting as a mediator that reduces direct communication overhead and processing load on the server while maintaining centralized control capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a server monitors the operating state of each projector, then system monitoring capability is improved, but the complexity of the control system increases

Engineering Contradiction:
Improvesystem monitoring capabilityVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The projector's control unit autonomously monitors its own operating state and executes control instructions without requiring continuous server intervention. This self-service capability reduces the need for complex centralized monitoring systems while maintaining reliable system oversight through local intelligence.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The control unit is pre-configured with control instructions and parameters from the information processing device before operation begins. This preliminary configuration allows the projector to autonomously execute control operations and monitor its state without requiring real-time server intervention, reducing system complexity while maintaining monitoring capability.

Inventive Principle:
Principle #10Preliminary action
