Solution Overview

Problem

Panel shutters with rigid shutter elements are prone to damage due to deformations, which can lead to malfunction and further damage when deformed elements contact the lintel or wall, causing potential tearing or inner layer damage.

Innovation Solution

A detection arrangement using a transmitter-receiver assembly is integrated to detect deformations in shutter elements, allowing for altered operation to prevent damage, comprising transmitters and receivers embedded in side rails to emit and receive detection signals, with a controller to trigger reactions such as stopping the door blade movement upon deformation detection.

Solution Approach 1:

The detection arrangement is installed to detect deformations before they cause serious damage. The system proactively identifies deformed shutter elements and triggers a warning signal or stops the shutter operation in advance, preventing the deformation from worsening or causing catastrophic failure.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The detection arrangement provides continuous monitoring feedback on the condition of shutter elements. When a deformation is detected, the system responds by issuing a warning signal or stopping operation, creating a closed-loop control system that prevents damage accumulation.

Inventive Principle:
