Solution Overview

Problem

Conventional methods for representing the presence of objects, such as people or substances, in organizational settings are inefficient as they require manual updates and fail to accurately depict changes in situation or location, especially in multi-departmental environments.

Innovation Solution

An object image displaying system comprising multiple cameras and a server that identifies object positions and selects corresponding image data for display, allowing automatic updating and precise representation of object presence and situation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual message or memo methods are used to track object presence, then the system is simple to implement, but the presence information is not updated automatically and requires manual effort

Engineering Contradiction:
Improveautomatic presence updateVSAvoidsystem complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The system enables automatic presence information updates through self-service mechanisms. Sensors and cameras automatically detect object presence and location without requiring manual input from users. The system autonomously captures images, identifies objects, and updates presence information in real-time, eliminating the need for manual message or memo updates while maintaining simplicity through automated operations.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical methods (writing messages or memos) with automated sensing and imaging systems. Cameras and sensors substitute for human actions of updating presence information manually. The system uses automated image capture and processing to track object presence, replacing the mechanical act of writing and updating physical or digital notes with an automated electronic system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If conventional message or memo systems are used, then the system is easy to operate, but it cannot accurately represent changes in object situation or location

Engineering Contradiction:
Improvepresence information accuracyVSAvoidsystem operation simplicity
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system creates accurate visual copies of object presence and location through image capture. Instead of relying on text-based messages or memos that may not accurately represent the situation, the system captures actual images of objects and their locations, providing a precise visual copy of the real-world state. This ensures accurate representation of presence information while maintaining ease of operation through automated image-based tracking.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces an intermediary system consisting of cameras, sensors, and processing units that mediate between the physical object and the presence information representation. This intermediary automatically captures and processes visual data, translating physical presence into accurate digital information without requiring direct manual intervention. The intermediary system bridges the gap between simple operation and high accuracy by automating the information capture and representation process.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If multiple cameras are deployed to track object positions precisely, then location accuracy is improved, but the device complexity and cost increase

Engineering Contradiction:
Improveobject position accuracyVSAvoidcamera system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system segments the monitoring area into multiple zones, each covered by specific cameras. Instead of using a single complex camera system to track all objects everywhere, the patent divides the space into segments and assigns cameras to specific segments. This segmentation allows for accurate local tracking in each zone while reducing overall system complexity by limiting each camera's coverage area and functionality requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by optimizing camera placement and configuration for specific local areas rather than using uniform high-complexity cameras throughout. Each camera is positioned and configured to provide optimal coverage for its specific location, using appropriate resolution and field-of-view settings for that particular zone. This approach achieves high position accuracy where needed while reducing overall system complexity by not over-specifying cameras in all locations.

Inventive Principle:
Principle #3Local quality
