Solution Overview

Problem

Managing and overseeing equipment systems across multiple geographic locations with varying maintenance schedules and characteristics is challenging due to the large volume of data and geographical distribution, as seen in existing systems like the elevator maintenance business support system.

Innovation Solution

A graphical user interface that displays equipment locations and status using icons, with varying display characteristics based on operational conditions, and provides health scores, uptime indicators, and activity histories, allowing for interactive map views and detailed component schematics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If detailed equipment servicing data is transmitted to all monitoring access systems, then comprehensive equipment status information is available, but network traffic increases significantly

Engineering Contradiction:
Improveequipment status information availabilityVSAvoidnetwork traffic
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The system extracts only the essential equipment status information and summary data from the comprehensive data repository, transmitting only what is necessary to monitoring access systems. This selective extraction reduces network traffic while maintaining the availability of critical equipment status information.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The data repository is segmented into different data types and access levels. The system provides summarized results for general monitoring while allowing detailed data access only when specifically requested or when viewing from the central location, thereby reducing unnecessary network traffic.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple monitoring access systems access the complete data repository, then all systems have full equipment data, but data transmission and processing overhead increases

Engineering Contradiction:
Improvedata access flexibilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system implements local quality by providing different data views to different monitoring access systems based on their specific needs and locations. Each system receives customized summarized results appropriate to its function, rather than all systems receiving identical complete data sets.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The data repository system dynamically adjusts what data is transmitted to each monitoring access system based on real-time requirements, user permissions, and system priorities. This dynamic adaptation allows flexible data access while optimizing transmission efficiency.

Inventive Principle:
Principle #15Dynamics

3Loss of information

If comprehensive equipment data is displayed at all locations, then complete information is available everywhere, but display complexity and information overload increases

Engineering Contradiction:
Improveequipment information completenessVSAvoidinterface usability
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The graphical interface extracts and displays only the most relevant equipment status information at each monitoring location, rather than showing all available data. This selective display maintains information completeness for critical parameters while avoiding information overload.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system displays summarized results that provide partial information sufficient for most monitoring purposes, with the option to access complete detailed data when specifically needed. This partial display approach improves usability while maintaining access to complete information.

Inventive Principle:
Principle #16Partial or excessive action
