Solution Overview

Problem

Elevator systems face challenges in maintaining precise positioning of elevator cars due to vibrations and twisting of information carriers, which can lead to damage and noise, especially in high systems, as existing solutions fail to effectively stabilize the carriers and ensure fault-free reading.

Innovation Solution

A device with retaining and clamping elements is used to stabilize the information carrier within the elevator shaft, employing clamping force transmission means and magnetic forces to prevent vibrations and twisting, allowing the reader to be guided closely to the carrier while ensuring precise positioning and damping of vibrations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the information carrier is held and tensioned at both ends to run vertically through the elevator shaft, then the carrier can extend through the entire shaft height, but the carrier is excited to vibrate and can strike adjacent devices or shaft walls causing damage and noise

Engineering Contradiction:
Improvelength of information carrierVSAvoidvibrations and damage
Core Design Contradiction:
Length of moving objectVSObject-affected harmful factors

Solution Approach 1:

The information carrier is divided into multiple sections with vibration isolation elements (dampers) positioned at specific intervals along its length. These dampers segment the carrier into independent vibration zones, preventing continuous vibration propagation and reducing the risk of the carrier striking adjacent devices or shaft walls.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Vibration isolation elements (dampers) are pre-installed at strategic positions along the information carrier to provide beforehand cushioning against vibrations. These dampers are positioned in advance to prevent vibration-induced damage before it occurs, cushioning the carrier against striking adjacent devices or shaft walls.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Shape

If the information carrier is held and tensioned at both ends, then the carrier maintains vertical alignment, but the strip twists in opposite directions along the longitudinal axis impairing fault-free reading

Engineering Contradiction:
Improvevertical alignment of carrierVSAvoidtwisting stability
Core Design Contradiction:
ShapeVSStability of the object's composition

Solution Approach 1:

The information carrier is segmented into multiple sections with vibration isolation elements positioned at specific intervals. These segments can independently accommodate twisting movements without affecting the entire carrier, allowing local adjustment while maintaining overall vertical alignment for fault-free reading.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The vibration isolation elements provide parameter changes in the form of controlled flexibility and damping characteristics. This allows the carrier to maintain vertical alignment while accommodating twisting movements through the dampers, preventing twist-induced reading errors by absorbing the twisting energy.

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If a detection device is arranged close to the information carrier for precise position determination, then position accuracy is improved, but the carrier vibrations cause the carrier to strike adjacent devices or shaft walls

Engineering Contradiction:
Improveposition determination accuracyVSAvoidvibrations causing damage
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

Vibration isolation elements are pre-installed along the information carrier to provide beforehand cushioning against vibrations. This allows the carrier to be positioned close to the detection device for high precision position determination while the dampers prevent vibration-induced striking of adjacent devices or shaft walls.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The carrier is segmented into vibration-isolated sections that can be positioned close to the detection device for precise measurement. The segmentation with dampers prevents vibration propagation, allowing close positioning for accuracy while protecting against harmful vibrations.

Inventive Principle:
Principle #1Segmentation

AI summary

An elevator system vibration stabilizer device retains an information carrier extending through an elevator shaft at at least one point of the information carrier and includes a retaining element and a clamping element according to an assembly method. The clamping element is connected to the information carrier at the at least one point by a clamping force transmission device whereby the information carrier is applied with a clamping force against at least one contact region on the retaining element. The retaining element is stationary in the elevator shaft. A magnet element is an alternative to the clamping force transmission device. The vibration stabilizer device is included in an elevator system shaft information system to provide a method for preventing vibrations of the information carrier.
