Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing elevator systems require cumbersome processes for initiating an elevator call from a remote location, involving manual input or scrolling on a mobile device to select source and destination landings, which is inconvenient and time-consuming.

Innovation Solution

A system and method using a call input device with a graphical user interface featuring moveable graphical objects on a touch screen, allowing users to select current and destination floors through touch or voice commands, with suggested options based on travel history, to initiate elevator service more intuitively and efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional mobile device input methods are used to initiate elevator calls, then the system can record source and destination landings, but the process becomes cumbersome and time-consuming

Engineering Contradiction:

Improveelevator call initiation accuracyVSAvoidtime to initiate elevator call

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system pre-loads floor options and automatically detects the current floor, so when the user needs to initiate an elevator call, the most likely options are already prepared and ready for selection, eliminating the need for manual scrolling through all floors

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system automatically detects the current floor and suggests destination floors based on travel patterns, allowing the elevator call initiation process to serve itself by providing intelligent defaults rather than requiring complete manual input from the user

Inventive Principle:

Principle #25Self-service

2Ease of operation

If manual scrolling and input methods are used on mobile devices, then floor selections can be made, but the operation becomes inconvenient and complex

Engineering Contradiction:

Improveease of initiating elevator callVSAvoidinput process complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The invention extracts the complex scrolling and selection interface from the traditional mobile device keyboard input, replacing it with a simplified graphical floor selection interface that presents only relevant floor options visually, removing the need for extensive scrolling and typing

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The floor selection interface dynamically adapts to user needs by automatically highlighting the current floor, suggesting destination floors based on historical patterns, and reordering floor options based on likelihood of selection, making the interface responsive and adaptive rather than static

Inventive Principle:

Principle #15Dynamics
