Solution Overview

Problem

Existing elevator maintenance systems face challenges in accurately and conveniently inputting failure treatment results due to manual and error-prone processes, leading to incomplete data entry and hindered utilization of maintenance data.

Innovation Solution

A maintenance terminal with sequential selection input screens and a failure diagnosis server that assists maintenance workers in accurately inputting failure treatment results by displaying predicted error codes and guiding through a series of selection buttons, allowing unskilled workers to perform maintenance tasks efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual writing and hand inputting is used to input failure treatment result, then maintenance worker can freely input data, but input accuracy deteriorates and processing steps may be missed

Engineering Contradiction:

Improvefreedom of data inputVSAvoidinput accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The failure treatment result input process is divided into multiple sequential screens (component selection screen, error code selection screen, treatment process selection screen). Each screen handles a specific aspect of the input, guiding the maintenance worker through structured choices rather than requiring freehand input of complex data structures.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The maintenance terminal acts as an intermediary system between the maintenance worker and the failure treatment result recording. Instead of directly inputting data into a complex system, the worker interacts with simplified selection interfaces on the terminal, which automatically formats and validates the input data.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If manual input method is used, then maintenance worker can input data in own way, but reliability of failure treatment result deteriorates due to incomplete data entry

Engineering Contradiction:

Improveflexibility in data inputVSAvoidcompleteness of failure treatment result

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system presents preliminary organized information (component list, error code list, treatment process list) on each screen before the maintenance worker makes selections. This pre-organization ensures that all necessary data categories are covered and guides the worker to provide complete information without requiring them to remember all possible input options.

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If complex manual input process is used, then detailed data can be input, but time consumption increases and productivity decreases

Engineering Contradiction:

Improvedetailed data input capabilityVSAvoidinput speed

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The maintenance terminal automatically generates and presents the lists of components, error codes, and treatment processes based on the selected category. Instead of requiring the maintenance worker to manually search or type these detailed lists, the system self-generates the relevant information and presents it for selection, significantly reducing input time while maintaining detail accuracy.

Inventive Principle:

Principle #25Self-service

4Ease of operation

If manual writing input is used, then maintenance worker can input according to their understanding, but measurement precision of error codes deteriorates leading to incorrect coding

Engineering Contradiction:

Improvesubjective input freedomVSAvoiderror code accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The system displays standardized error codes and their descriptions as templates that the maintenance worker can select. Instead of requiring the worker to remember or type error codes from memory, the system provides accurate error code information as copies that can be directly selected, ensuring precision while maintaining ease of operation.

Inventive Principle:

Principle #26Copying
