Solution Overview

Problem

Existing elevator systems require passengers to manually input floor information, which can lead to inefficiencies and hinder the implementation of other functions due to the need for wireless connections.

Innovation Solution

Implementing a radio signal apparatus, such as a Bluetooth or BLE module, that broadcasts an identity with a floor information bit, allowing passengers' mobile terminals to automatically acquire current floor information without establishing a connection, thereby optimizing connection capacity for other functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a wireless terminal module is mounted in the elevator system to interact with personal mobile terminals, then passenger experience is improved through automatic call functions, but connection capacity is consumed and other functions are hindered

Engineering Contradiction:
Improveautomatic call functionVSAvoidconnection capacity
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent segments the information transmission from the connection establishment. The elevator system transmits floor information through broadcast signals that do not require a wireless connection, separating the information acquisition function from the connection function. This allows the wireless module to remain available for other functions like automatic calls while still providing floor information.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts the floor information transmission from the connection-based communication protocol. By using broadcast signals that carry floor information independently of any established connection, the system removes the dependency between connection establishment and information acquisition, freeing up connection capacity for other purposes.

Inventive Principle:
Principle #2Taking out (Extraction)

2Productivity

If manual floor information input is required, then connection capacity is preserved for other functions, but efficiency is reduced and passenger experience is hindered

Engineering Contradiction:
Improvefloor information acquisition efficiencyVSAvoidmanual input requirement
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent implements self-service by having the elevator system automatically provide floor information through broadcast signals. The personal mobile terminal automatically receives and processes this information without requiring manual input from the passenger, making the system serve itself in terms of information provision.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The elevator system performs preliminary action by broadcasting floor information in advance and continuously, so that when a passenger needs this information, it is already available for automatic acquisition. This eliminates the need for manual input at the moment of need.

Inventive Principle:
Principle #10Preliminary action

3Loss of information

If wireless connection is established for floor information acquisition, then floor information can be obtained, but connection capacity is consumed and other functions are hindered

Engineering Contradiction:
Improvefloor information acquisitionVSAvoidconnection capacity availability
Core Design Contradiction:
Loss of informationVSAdaptability or versatility

Solution Approach 1:

The patent segments information transmission from connection establishment. Floor information is transmitted through independent broadcast signals that do not require a wireless connection, separating these two functions. This allows the wireless module to provide floor information without consuming connection capacity, preserving it for other functions like automatic calls.

Inventive Principle:
Principle #1Segmentation

4Loss of time

If manual floor information input is required, then connection capacity is preserved, but time is lost and efficiency is reduced

Engineering Contradiction:
Improvefloor information input timeVSAvoidoverall system efficiency
Core Design Contradiction:
Loss of timeVSProductivity

Solution Approach 1:

The system automatically provides and transmits floor information through broadcast signals, eliminating the need for manual input. The personal mobile terminal automatically receives this information, saving time and improving efficiency without requiring additional connection capacity.

Inventive Principle:
Principle #25Self-service
