Solution Overview

Problem

Elevator control systems lack the intelligence to efficiently manage diverse user and device requests, particularly in urban environments where varied elevator resource demands need to be effectively allocated.

Innovation Solution

An elevator control system that includes call-out units and a control unit capable of receiving multi-dimensional call request messages containing user or device identification and resource demand features, such as space size, weight, priority, and restrictive requirements, to generate dispatching commands for elevator cars, with features stored in local memory and/or cloud for efficient matching and allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional elevator control systems are used, then the system structure is simple, but the system cannot efficiently manage diverse user and device requests with varied resource demands

Engineering Contradiction:
Improvecapability to manage diverse user and device requestsVSAvoidsystem structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The call request message is segmented into multiple dimensional features including user identification, resource demand features (space size, weight, priority, restrictive requirements), and departure floor identification. This segmentation allows the control system to process and match different types of requests independently, improving adaptability while maintaining manageable system complexity through structured data organization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces multi-dimensional features for call requests, transforming the traditional single-dimension floor-based calling system into a multi-dimensional matching system. By adding dimensions such as user identification, space requirements, weight constraints, priority levels, and restrictive requirements, the system can handle diverse scenarios including passenger and device transportation, significantly enhancing versatility.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Measurement precision

If multi-dimensional call request messages with user identification and resource demand features are implemented, then dispatching accuracy is improved, but information processing complexity increases

Engineering Contradiction:
Improvedispatching matching accuracyVSAvoidinformation processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary processing by storing user profiles with their resource demand features (space size, weight, priority, restrictive requirements) in advance in local memory or cloud databases. When a call request is received, the control unit retrieves the pre-stored profile using the user identification, avoiding real-time complex calculations and reducing processing complexity while maintaining high matching accuracy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary layer in the form of local memory and cloud storage that mediates between the call-out units and the control unit. This intermediary stores and manages user profiles, allowing the control unit to efficiently retrieve and match user requirements without directly processing all raw data, thereby reducing information processing complexity while maintaining dispatching precision.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If user identification and resource demand features are collected and stored, then resource allocation efficiency is improved, but data storage and management requirements increase

Engineering Contradiction:
Improveelevator dispatching efficiencyVSAvoiddata storage requirements
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent merges multiple data elements (user identification, space size, weight, priority, restrictive requirements) into a single integrated user profile stored in local memory or cloud databases. This consolidation reduces redundant data storage and simplifies management compared to storing separate data structures for each feature, thereby improving dispatching efficiency while minimizing data storage requirements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

Instead of storing complete and detailed user information in every system component, the patent uses identification-based copying where the control unit retrieves necessary profile data from centralized storage (local memory or cloud) only when needed for dispatching decisions. This on-demand copying approach reduces overall data storage requirements while maintaining the ability to access complete user profiles when required for efficient resource allocation.

Inventive Principle:
Principle #26Copying
