Solution Overview

Problem

When a large-sized sensor is mounted to a measurement target using existing mounting tools, it interferes with adjacent ropes, preventing accurate tension measurement.

Innovation Solution

A mounting tool for an elevator rope tension measurement device comprising a first holding body to hold a rope, a second holding body to hold the tension measurement device, and a connecting body to position the device away from the rope, ensuring non-interference.

1Strength

If a large-sized sensor is mounted to the rope using the existing mounting tool, then the sensor can be securely attached to the measurement target, but the sensor interferes with adjacent ropes and prevents accurate tension measurement

Engineering Contradiction:
Improvesensor attachment securityVSAvoidtension measurement accuracy
Core Design Contradiction:
StrengthVSMeasurement precision

Solution Approach 1:

The mounting tool positions the sensor in a different spatial dimension by extending it away from the rope surface. The sensor is mounted on the extending portion rather than directly on the rope, changing the measurement dimension from surface-level to extended-space, thereby avoiding interference with adjacent ropes while maintaining measurement capability

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

Solution Approach 2:

The extending portion acts as an intermediary element between the rope and the sensor. This intermediate structure transmits the rope's vibration to the sensor while maintaining spatial separation, allowing the sensor to measure tension without directly contacting the rope and interfering with neighboring ropes

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

There is provided a mounting tool for an elevator rope tension measurement device, the mounting tool being capable of preventing the rope tension measurement device from interfering with a rope disposed adjacently to a rope that is a measurement target. A mounting tool for an elevator rope tension measurement device includes: a first holding body configured to hold a rope of an elevator; a second holding body configured to hold a rope tension measurement device that measures a tension of the rope; and a connecting body configured to connect the first holding body with the second holding body so as to dispose the rope tension measurement device at a position away from the rope.
